Dear All,
Is there any detailed information (characteristics) available when using AVCC as ADC reference source (ADC12VRSEL=0000b)?
Of interest are:
AVCC test condition / Minimal AVCC for full ADC operation?
Thanks for your help,

Hi, I have a macbookpro 2015 and am unable to debug or flash the code into the launchpad. It repeatedly gives the same error . USB FET not initiallized
Part Number: MSP432E401Y
We are considering using the MSP432E401Y as a common controller for providing ethernet connectivity for several PCBAs in a complex machine design. It is critical in this role that the MSP432 be compatible with existing HW. On several PCB's we use the Delfino (TMS320F28379D) for sampling and processing sensor inputs. Specifically the Delfino'ss McBSP is used to communicate processed ADC sample information downstream for further processing. If we select the MSP432, we will need the delfino to communicate with the MSP432E401Y microcontroller.
The current application has the Delfino using its McBSP as a transmit only port configured to drive its transmit clock, frame sync and data running at 50Mbps. Is the MSP432's QSSI peripheral's receiver compatible with a McBsp transmitter and one running at 50Mhz? Looking at the MSP432 data sheet, I see no timing information on the frame sync (its shown in diagrams but does not seem to specify any timing info in the tables). Further both the data sheet and technical reference manual speak of "Legacy" modes where the max serial clock rate looks to be only 10MHz and appears to behave more like an async transfer with requirements that the SysClk must be 12X the SSI clock.
Can you speak to the McBSP compatibility as a slave receiver to a McBSP transmitter at preferably 50Mbps rates (minimum continuous speed of 24Mbps)? If it is compatible, can you recommend mode of operation and configuration settings?
BTW: We are aware of the new Delfino (F28388) with ethernet connectivity. It is very possible that it could serve the role of a common ethernet interface and we will be posting some questions we have on it soon. It NOT being production released is a real concern for us and we are investing other avenues like the MSP432. I did not want to confuse this particular post by encapsulating it inside a larger conversation (at least to start) but I wanted you to be aware and am glad to discuss the F28388 if it makes sense to you as well.
Thank you in advance for your support.

Part Number: MSP430FR6043
I am having an issue with the SPI functionality on the MSP430FR6043 when trying to map it to port PJ (pins PJ.0-PJ.3). The MOSI signal on PJ.2 works fine, but the clock does not appear on PJ.0 at all. When mapped to port P5 (P5.0 - P5.3) everything works as expected. I double check the electrical connection by setting the PJ.0 as a digital IO and sending out some pulses, which registered on the scope correctly. I repeated this test on three separate devices, with the same results. I tried both with an SPI device connected, and with the MCU pin floating. I don't think the pins on port PJ are entering JTAG mode, the SYSJTAGPIN is 0, and the device behaves the same when debugging with SPW, as well as when running off battery with the SPW programmer disconnected and the RESET pin pulled high at all times. Could there be something else preventing the PJ.0 pin from muxing into the SPI clock on the UCA2 module? Please advice. I would really appreciate having these pins specifically available for that feature, as I am working with a very tight PCB layout, and the position of the USS module and the LCD is fixed, leaving me very little wiggle room.
Attached: scope trace from pin P5.2 (working) and PJ.0 (not working), and the test code I ran. The tests were performed on a custom PCB, with either the PJ.0 pin floating (connected only to a scope probe), or connected to an SPI slave device thought a 22R resistor. Debugged with an MSP FET, over a SBW connection with only the SBWCLK and SBWTDO pins connected. Thanks for any input!

I use the I2C sample (master code) from TI. It works with a slave devive with an address below 0x3F. If I send to an device with an address of 0x7F or higher than the I2C machine of the MSP430FR5949 set the highest bit to zero. The result is an address lower then 0x3F.
The problem is I have to communicate with an RFID-IC with a address for write of 0xA6 and an address for read of 0xA7. The controller send only 0x26 and 0x27 to the slave device. It is a 6-bit address room plus R/W-bit only.
Could you help me? What have I to change in the initialisation? Could you send a sample of initialisation code with interrupt routine?
Best Regards

Hi,
We are attempting to update application firmware by using the bootloader inJTAG/SWD lock mode. The reference document for our testing is: www.ti.com/.../slau690e.pdf
The unencrypted firmware binary is first transferred via custom firmware into the memory location: 0x0002.0000 (as shown on Figure 10 of the manual above)
JTAG/SWD lock parameters are set to their default state and flashmailbox is cleaned out prior to update.
Then we configure the flashmailbox as shown below:
/* Setup the flash mailbox */ uint8_t flashMailBox[0x290]; memset(flashMailBox, 0xFF, sizeof(flashMailBox)); /* Unprotecting Info Bank 0, Sector 0 */ FlashCtl_unprotectSector(FLASH_INFO_MEMORY_SPACE_BANK0, FLASH_SECTOR0); /* Erase the flash mailbox */ FlashCtl_eraseSector((uint32_t) flashMailBox_ptr); /* Set flash mailbox start */ * (uint32_t *) (&flashMailBox[0x0000]) = (uint32_t) 0x0115ACF6; /* Set flash mailbox command to firmware update (SEC_ZONE0_UPDATE ) */ * (uint32_t *) (&flashMailBox[0x0004]) = COMMAND_JTAG_SWD_LOCK_ENC_UPDATE | COMMAND_JTAG_SWD_LOCK_SECEN; /* Enable JTAG/SWD lock */ * (uint32_t *) (&flashMailBox[0x0010]) = (uint32_t) 0x00000000; /* Set address of uploaded firmware */ * (uint32_t *) (&flashMailBox[0x01F8]) = (uint32_t) 0x00020000; /* Set length of uploaded firmware */ * (uint32_t *) (&flashMailBox[0x01FC]) = (uint32_t) sector * D_OS2SAS_SYS_FLASH_SECTOR_LENGTH + 0x10; /* Set the destination address after decryption */ * (uint32_t *) (&flashMailBox[0x0200]) = (uint32_t) 0x00001000; /* Set flash mailbox end */ * (uint32_t *) (&flashMailBox[0x028C]) = (uint32_t) 0x0011E11D; /* Program the flash mailbox */ FlashCtl_programMemory(&flashMailBox, flashMailBox_ptr, sizeof(flashMailBox)); /* Protecting Info Bank 0, Sector 0 */ FlashCtl_protectSector(FLASH_INFO_MEMORY_SPACE_BANK0, FLASH_SECTOR0);
Basically, the code above sets the flashmailbox configuration to exactly what Figure 14 in the reference manual states. We do not invoke any BSL hardware pin parameters since the firmware update is being done internally and not via JTAG/SWD or BSL.
Few questions:
Can it be assumed that the application firmware memory address destination is 0x0000.1000 as shown in the manual?
Is there an acknowledgement field for successful update via JTAG/SWD lock firmware update as there is in the Secure IP Zone Update (0xACE vs 0xDEAD)? How do we confirm it updated the firmware correctly? Is there maybe even a way to perform this update without JTAG/SWD lock since we are doing it internally (triggered by custom UART driver calling the update firmware) not by an external interface.
Regarding the GUI (MSP432P4xx Security and Update Tool) - www.ti.com/.../MSP432-SECURITY-AND-UPDATE-TOOL
On the JTAG/SWD Lock Update tab - Update Firmware within the program, How do we generate an output encrypted firmware image? Does the encrypted version of the firmware need to be the input binary to the update?
Last question, why has the tool been deprecated as of Rev D? Couldn't find the exact reference in the SLAA700A that pertains to this functionality.
Thank you,
Best,
Robert

We are using MSP430.dll to load the firmware into our device. We want to burn the fuse/set bit to the device after loading the firmware. I am not the original developer of the code that calls the dll and I am not able to locate the header for the dll.
So first question can the dll be used to set the bit, and if so what is the parameter to pass to the dll to do so.
Thanks in advance

Dear Sir,
We want to add bootloader facility in our product that requires single image bootloader facility using UART.
As we have found some reference for the same by application note of SLAA600D.
.
And we make some changes in the lnk_msp430f47177.cmd according to our uC MSP430F47177.
Our problem with the code is it doesn't reset the code and go to main() during Debug mode.
Please suggest the changes in the below code attach if any we also attach the file folder for the same.(Please visit the site to view this file)

I have two TI controllers one is MSP430f5529 and other is MSP430f5329.
I setup UART interrupt communication protocol for communicating each other(full duplex communication).
Now the 5529 code part also have a timer setup with interrupt
The problem is my timer is running in background and in the while part i send some data to other msp5329 for a certain condition.
when my program reaches to send part of uart its automatically goes to UART interrupt part. and after that return to send function
i dont know how to solve this strange problem because timer have different interrupt and uart has different.
Here is my code of MSP430F5529.
void main()
{
Timer();
uartInit();
__enable_interrupt();
while(1)
{
//certain condition
send_uart("abcdef");
}
}
void Timer()
{
TA0CCTL0 = CCIE; // CCR0 interrupt enabled
TA0CCR0 = 1850;
TA0CTL = TASSEL_2 + MC_1 + TACLR;
}

Hello
I am interested in developing an application for I2C communication with the bitbang method.
Are there any examples, or does anyone have any suggestions?
Hardware: 2x MSP432P401R Launchpad
Software: I 'm currently use the driverlib for MSP432.
Thank you in advance

Hello,
In the SimpleLink MSP432E4 SDK 3.20.00.10 v. - the httpserver example is not working to me. I have the following error message:

Hello,
I am working on MSP432#401Y Launchpad. I have loaded i2c example program which reads the temperature from on board sensor.
The example code suppose to measure the temperature and display.
However, I observed that even when the program is halted at a specific break point and I try capturing the data on pins I2CMSP432E4_PN5_I2C2SCL and I2CMSP432E4_PN4_I2C2SDA.
It displays some data on the both the pins.
As per my understanding there should not be any data when its program is halted it could be at max either continue to be HIGH or LOW
Problem-1:
Should there be some data when debugger is halted?
Problem-2:
As I see the example code it calls the I2C_Transfer function for address and returns FALSE to enter in to while loop for ever. It seems to be the error where it is not able to resolve the sensor.
Any clue? why does it return false? Am I missing any config?
if (!I2C_transfer(i2c, &i2cTransaction)) {
/* Sensor error, Could not resolve a sensor, error */
while(1);
}Question-1:
Also, I want to use I2C0 instead of I2C2 port used in example code.
Is that enough if I update the struct parameter in below struct for using I2C0 port or need to change some other code piece as well?
I could not trace any other place than the below struct where I2C port is been mentioned in example code
/* MSP_EXP432E401Y.c */
const I2CMSP432E4_HWAttrs i2cMSP432E4HWAttrs[MSP_EXP432E401Y_I2CCOUNT] = {
{
#if 1 //This is what I want
.baseAddr = I2C0_BASE,
.intNum = INT_I2C0,
.intPriority = (~0),
.sclPin = I2CMSP432E4_PB2_I2C0SCL,
.sdaPin = I2CMSP432E4_PB3_I2C0SDA,
.masterCode = 0x08
#else //Example code
.baseAddr = I2C2_BASE,
.intNum = INT_I2C2,
.intPriority = (~0),
.sclPin = I2CMSP432E4_PN5_I2C2SCL,
.sdaPin = I2CMSP432E4_PN4_I2C2SDA,
.masterCode = 0x08
#endif
}
};
Thanks
