Hi all,
I am trying to write to infoB of MSP430G2553 using,
#pragma DATA_SECTION(var_a, ".infoB")
const int var_a = 980;
But if I replace the infoB with infoC then I am able to write to infoC but not to infoB, is there any way possible to write to infoB as I have utilized the entire infoC and infoD. Can't use the infoA because of clock calibration data.
Thanks

Hi,
Looking at the datasheet, there is quite a large error across the voltage/temp range for the 32kHz crystal oscillator. But I'm more interested in the error at a fixed voltage and fixed temperature. In this case, would the error approach that of the crystal tolerance spec? We are using MSP's internal loading caps, but they are not specified with a min/max (only typ) in the datasheet, so will they have their own process variation that would increase the error? If so, any idea how much? We are using a 20ppm tolerance crystal, trying to figure out if our overall error would be near that, or 40ppm, or 100ppm, or ???
Thank you,
Erik

Hi
I've just bought brand new development kit. I've got IAR embedded workbench innstalled, however I cant upload any program to microcontroler.
Looks like there is a problem with usb driver because device manager says "USB device not recognized device descriptor failure"
The same situation occurs for my laptop and PC.
I've tried to installl this http://www.ti.com/tool/mspds

Dear all,
I am trying to use Booster Sensor 1 capacitive touch with MSP432. There are few programs are given on the net since TI has stopped supporting this device.
There are some nice sketches from Robert Wessels, year 2012. Unfortunately when I run those programs I get the following errors:
=========================================================================================

And many more which I have not bother to include. There are all in the same context.
I have his header file, but I am sure I missing something extra. Can somebody help me since I have to take care of lecture regarding the capacitive sensor using MSP432.
Thank you in advance.

Hi,,
I am using "nvsinternal" example program for my application.
Using that application i am able to write the data on to the flash memory and read the flash memory.
However i would like to write the data on to the specific memory location and read when needed.
As per the example the Base address is : 0xE0000 and sector size is: 0x4000. that means i can write the data from (0xE0000 to 0xE3FFF).
If at all i want to write the data to the location (0xE2000) then how to initialize the write address to the nvs handle while writing and reading the location.
Thank you
Regards
Kalyan.

As the flow picture, the Area is meter constant, and I get my meter constant around 25.434.
( 3.14 * 0.015 * 0.015 * 0.08 ) / 8 = 0.000007065 (m3/s)
0.000007065 * 3600 * 1000 = 25.434 (L/h)
But TI's meter constant is 12742000 (L/h), what should I do to get the correct result?
Thank you.

I get an error message "Could not determine how this design was created. Xpedition xPCB Layout cannot be invoked on this design."
I was trying to open the layout file called "MSP-EXP430FR5969.pcb" that I obtained from the TI website for this evalue board.
I was using Mentor Graphics XPedition Enterprise X-ENTP VX.2.1 layout tool.
Questions:
1. What layout tool was the file created with?
2. Does TI have another file that I could use to view the layout? I just want to know the center-to-center distance between the J4 and J5 connectors. I suppose I could measure it, but I want to be exact and the layout files would give me the exact distance.

I am pretty sure that there is little development on driver lib any more, but:
We can set a pin high, we can set a pin low and we can toggle the pin, but why is there no MAP_GPIO_setOutputStateOnPin()?
I envision the signature like this:
MAP_GPIO_setOutputStateOnPin(int Port, int Pin, bool State)

Hello,
I am trying to blink the onboard LED every one second via a Timer A interrupt, but am failing to understand the logic of specifying the exact interval of the blinking. From what I understand from the users guide, the ACLK is driven directly by the crystal, which oscillates at 32768 Hz. It also says that the TAR increments on every rising edge of the clock signal. So, my immediate thought is that the TAR should overflow after exactly one second if I set the value of the compare register to be 32768, since there is one rising edge per cycle and 32768 cycles in one second. But, with the code I have pasted below, the interrupt triggers roughly every 20 seconds or so. This leads me to believe that the number that should be in TACCR0 is *much* lower than 32768, but I don't know how to calculate it. I'm wondering where my logic is breaking down. I am pretty new to microcontroller development so please forgive me ignorance of electrical engineering related concepts. Please have a look at my code below if you don't mind. Thanks.

TACCR0 |= 0x8000; // 32768 hz, which is the oscillation frequency of aclk
// SET CAPTURE/COMPARE CONTROL REGISTER TO DICTATE BEHAVIOR OF CAPTURE/COMPARE REGISTER

unsigned char tmp = UCA0RXBUF;
// Circular buffer NOT WORKING
read_buffer.write(tmp);
// Test buffer working
tmp_buf[tmp_buf_i] = tmp;
tmp_buf_i = (tmp_buf_i + 1) % 1024;
}
}
On reading/writing I have two CircularBuffer, tested and working, that store the data that should be write/read.
I have only tested RX reading, since I'm using a GPS module that doesn't require any command.
So I took the CircularBuffer class and tested it a part, but works! And the strange fact is that those foreign characters repeat...
Is there something I'm misunderstanding with MSP430 UART API usage?
Looks like the UCA0RXBUF (copied to tmp) passed to a function changes value. Maybe is the program Stack that is misread on interrupt calls?

I'm using the MSP430 Launchpad in my Microcontroller Applications class. The end goal of my project is to press a button on a keypad and have it output to a 7-segment display using I2C. I have the keypad code working already, but I can't get anything to send over I2C. I started with the msp430g2xx3_uscib0_i2c_08.c example code provided--I assumed it would be plug-and-play (after changing the slave address, of course).
I'm including the body of the example code that I adapted from referencing a working code for the MSP430F5529. The primary problem I'm having currently is that I can't find a vector word for I2C (UCB0IV in this code) for the MSP430G2553. I've combed through a few different datasheets and have been unable to find anything that works. Does anyone have any idea what I can replace that with to get this code working for my 7-segment? Or is this method just not going to work with the MSP430G2553? (Our professor recommended bit-banging, but I'd rather take a cleaner approach if that's possible.)
Thank you!

My customer is concerned with FRAM as follows.
<Question>
He saw about the possibility of destroying Flash with the following document (MSP430 Advanced Technical Conference), but will phenomenon like the document occur in MSP430FRAM as well?
Customers sometimes experienced memory bugs like Flash events on events like ATC.
They are considering MSP430FRAM products and worry about the same symptoms as Flash does not occur.
Please let me know if it is not occur with MSP430FRAM.

Hi,
In the MSP430G2553,two values are received as an input and will increment based on the reception.
If P2.1 is low , then these two received values should multiply and store on to the RAM for every 15minutes interval and get accumulated on to a particular place, until the P2.1 goes high.
Based on these accumulated value after P2.1 goes high.I will assign the functionality based on the accumulated values range.
This is the requirement of my code and can you please share any example code or any reference code for it.
I am working on IAR workbench.

On JTAG MSP430 wiki:
MSP430 JTAG interface is not 100% IEEE 1149.1 (JTAG) compatible. For example none of the MSP430 devices has Boundary Scan Cells. We only support the required command BYPASS, but don’t support the other required commands for example EXTEST and SAMPLE/PRELOAD.
Therefore there is no BSDL file for any MSP430 devices. In addition you can not put a MSP430 into a JTAG chain together with other devices.
Customer is wondering if there is no BSDL file, how do they verify chip in their factory, can we provide a way customer can verify device on their own?
