MSP430G2744: Timer TACCR
Part Number: MSP430G2744
Hi Team,
My customer has a question as below.
- Regarding timer A3, they plan on using clock at 300us, and the interrupt they are using is TACCR2 CCIFG. Does the timing chart in Fig. 12-3 TACCR0 CCIFG timing apply to TACCR2 CCIF as well? (As in, if TACCR0 were replaced by TACCR2, does the timing chart still apply?) If not, can you provide a timing chart for TACCR2 CCIFG?
- To calculate what value to set TACCRx, is the following correct? If not, can you provide the correct equation?
- TACCRx + 1 = User's desired period [sec] / timer clock freqeuncy [Hz]
Best regards,
Mari Tsunoda

MSP430F5438A: Not working Uart! I referred to an example.

Hello, Texas Team or Experts
My MCU have to communicate RS232 with MSP430F5438A.
So, I found the example of uart loopback in CCS Resource Explorer and then I downloaded firmware.
But, there are problems. Terminal didn't work using Hercules or CCS.
Also if I set transmitData = 'a', I hook up TX(TX-GND) or RX(RX-GND) with an oscilloscope, but the data value didn't check.
where is the problem?
I designed MCU and RS232(with usb)

MSP430F6736A: Increment in amplitude
Part Number: MSP430F6736A
Hi Team,
A customer has MSP430F6736A and is using SD24_B to acquire a sine signal and SMCLK is used as the clock source for the SD24. When SMCLK frequency is 1.1MHz ADC is working properly but when SMCLK frequency is changed to 24MHz an increment is observed in the amplitude of the acquired sample.
I have attached the captures here:
e2e.ti.com/.../SD24_5F00_Samples.xlsx
I hope you can help.
Thanks in advance,

MSP430FR4133: Is there a minimal SBW implementation in C to flash MCP430 serie from other MCU?
Part Number: MSP430FR4133
Everything is in the title, i use an MSP430 in a design where i routed the SBW interface to the main MCU, in the perspective of remote firmware upgrade.
I would like to implement this now and i wonder if there is some existing implementations, the smaller the better, all i need is to flash the firmware, no fancy option bits to set or anything.
I can imagine there is probably a 15K lines implementation of the MSP FET or something in some DLL, but i am looking for something more reasonnable, i have done that in the past for differnt MCU / SOC (ST, Cypress, Atmel) and it can be done in few thousand laines or less with SWD.
Thank you.

MSP430F5438A: ASM labels in C code unpredictable behavior?
Part Number: MSP430F5438A
Hi,
To make test automation, C code requires the ASM labels needs to added in code as shown attached screen shot.
But, TI document - SLAU132Y for MSP430, Section 6.6.5 has below statement
The Label usage is in below code:
The Label is added as shown above and working as expected and not seeing any issues in testing.
This code is being used for machine critical application, So could you please confirm, the label being used in C code as shown in above screen shot will result in unpredictable controller behavior?

MSP430FR2355: i2c clock stretching...how to use this???
Part Number: MSP430FR2355
I am communicating with a SenseAir CO2 sensor at 100kHz on I2C. I am having difficulty reading back registers after I write them....I typically read back 00 or FF.....This readback seems to be associated with the R/W register set as I can get back data from the read only block of registers.....The component is acking and nacking as expected even on the data. I tried slowing the clock down to 50khz and 25khz but still have the same issue....
I am thinking it may be something with clock stretching and am looking to try it but the user guide is quite sparse on how to do this....Can anyone tell me how to use the UCSCLLOW bit?
Thanks

MSP430FR2153: Using higher frequency than 32.768 kHz in LF mode (FR2xxx)
Part Number: MSP430FR2153
Hi experts,
Is it possible to connect a 38.4kHz crystal to XT1 with MSP430FR2153 (FR2xx series Clock System)?
My customer wants to do UART communication, but the device to connect to is fixed at 4800 bps. We believe that if we input a 38.4kHz crystal to ACLK=BCLK, we can theoretically communicate with an error rate of TX=±0%, RX=±6.25%. (This is when the accuracy of the crystal is ignored.)
I understand from the user's guide "NOTE: XT1 in HF mode configuration" that the input cannot exceed 40 kHz.
Best regards,

MSP-EXP430FR5739: Current draw too high - are there benchmark currents for example projects?
Part Number: MSP-EXP430FR5739
Other Parts Discussed in Thread: ENERGYTRACE,
Other Parts Discussed in Thread: ENERGYTRACE,
Hi,
I have been writing code for a new product using the part above. Functionally, the device is fine, but my code, which spends almost all of its time in a LPM4, is causing current draw of 2.4mA. This far too high, and can't be right. I've tried many example projects and they all take a large current like this.
I have also been unable to use EnergyTrace due to an error message "error communicating with FET USB1". All of the jumpers on the board are present, but the current doesn't change much whether they are there or not.
Do you have any "expected" currents for the particular example projects available for this board (so that I can test them) or could you test them for me please?
I am using a Keysight 34450A on 100mA range across the VCC jumper.
Can you tell me why the EnergyTrace doesn't work for me.. I've tried changing settings but nothing seems to work?
thank you

MSP430F5659: Reading 3 sensor outputs at the same time
Part Number: MSP430F5659
Hi Team,
Hope you are well!
I have the following requirements needed
- Some alternative to multiplexed ADC (need to communicate with at least 3 sensors with output for ADC)
- Low power usage
- At least 64KB flash and 16KB SRAM
- With standard peripherals such as: UART, I2C (one other sensor is I2C), and DAC (this will be connected to the feedback node of buck converter circuit in order to control the output voltage)
I was looking at the MSP430F5659IPZR as an option. For this MCU, it looks like the ADC channels are also multiplexed? Is this correct?
I’m not sure whether this would be fast enough for what we need. Say I need to read 3 sensor outputs at the same time – would this be possible?
Any recommendations are appreciated!
Thanks,
Connor

EVM430-FR6047: value of Number of pulses
Part Number: EVM430-FR6047
I have a question about the value of Number of pulses.
When we compared the measurement results when this value was set to 10 and when it was set to 20, we found that at a high flow rate of 4000 l/h, the 10 setting resulted in a larger variation.
Is this due to the fact that there are fewer values to correlate with the ADC?
Is there a recommended value for the number of pulses for accurate measurement? Please let me know if there is a minimum value that should be set higher than this, etc.
