MSP-EXP430F5529LP: Programming MSP430FR2633 using MSP-EXP430F5529LP

I think you need a captivate programmer (CAPTIVATE-PGMR) to read the data and then I can help you know what happens and how to adjust.

Now we have connected the CAPTIVATE-PGMR and able to read the data on captivate design center. But unable to detect the touch 

I would suggest you refer to this doc:https://www.ti.com/lit/ug/slau857a/slau857a.pdf?ts=1695102906651&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FMSP430FR2633

I think you need to change the threshold at here:

Yea i have changed the threshold value

Below is the current config.c code

I can't get what happens through the code, can you use the data logging function to log the data? You can find how to do that in the doc shared by me before.

Hi Eason Zhou,

Thank you for your response.

I've referred the doc you have shared for data logging function, same way have set the data logger in the GUI. The bar chart doesn't display any data.

Currently, we are utilizing the MSP430FR2633 to detect touch input on the TIDA-00343 touch panel. According to the user guide, we expected the delta value for the buttons to be around 50. However, it's concerning that we're seeing values ranging from 0 to 3 instead.

Could you please advise us on the next steps we should take to address this issue? Your guidance in simplifying and resolving this discrepancy would be much appreciated.

Below code for the data log is present in the CCS

Looking forward to your assistance.

Also have referred the doc https://www.ti.com/lit/ug/tidubj7/tidubj7.pdf?ts=1695295189872&ref_url=https%253A%252F%252Fwww.google.com%252F and updated the conversion count, conversion gain and counter filter beta value. There isn't any progress in the touch detection

Can you share your PCB design. It looks like that the signal is too small. You may need to change the hardware design.

we have used TIDA-00343 and wired it to MSP430FR2633IDA.

Before using the TIDA-00343 design, we used the TIDM-1021  reference design in mutual capacitance mode with buttons 1, 4, and 7 set for touch detection. Button 4 worked fine, but buttons 1 and 7 didn't work at all. When we pressed buttons 3, 6, and 9, it showed a strange negative touch response.

1. I think you need to make the wired trace to be as short as possible. Otherwise this sensivity will be influenced.

 2. Please put some picture to help me know what happens. Otherwise, I also don't know why "When we pressed buttons 3, 6, and 9, it showed a strange negative touch response."

Below is the connection made for both TIDA-00343 and TIDM-1021 reference design

Hi Pallavi,

What part you want it work? TIDA-00343 or TIDM-1021? I am a little confused.

One is for mutual mode, one is for self mode. Please make sure the used IO is different?

Can you give a summery of the problem you meet? Signal is small or the signal is negative?

I see you remove the resistor, I think it will affect TIDM-1021.

What about start from the code for these EVM?

Before touching, I suggest you add a cover on the PCB. otherwise the signal will be too strong.

Eason

I want to work with TIDM-1021 in mutual mode
thank you the suggestion to add cover on pcb. Will try and get back to you
