TIDA-01486: TIDA-01486 and EVM430-FR6047

Part Number: TIDA-01486

Hello,

I am designing TIDA-01486 to get better signal from 1 pair of piezo transducer on metal pipe (clamp on application). Following the below thread:

https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/835040/ccs-evm430-fr6047-tida-01486-mistakes

I have downloaded the updated software to control PD1 and PD2. We are not using MUX/Analog switch in our design therefore we do not need S1,S2, S3 and S4. Our plan is to first cross verify, is the updated software working fine and we want to see PD1 and PD2 should toggle from 0 to 1 or vise versa. I also managed to create new image file by replacing the 4 files (hal_system.c, hal_system.h, hmi.c and hmi.h) from updated software. Flashing has been done perfectly fine but I could not see toggling of PD1 and PD2, it is only a sinusoidal wave even without powering the EMV430-FR6047. I should suppose to see digital signal 1 or 0 on PD1 and PD2.

Please let me correct if I am wrong, I am connecting the oscilloscope probe on connector J6 pin 16 for PD1 and connector J5 pin 9 for PD2.

Hi,

The software update that you are using is for 2 transducer pairs. However, I believe you are only using one correct? Which transducer pair have you selected in the GUI? From the post you linked:

Yes I am using one pair of transducer and on the GUI I have written 1 in the block of User Param #10

Hi,

If you are only using one transducer pair, why do you need this software update?

Evan

Hi,

Without software update, how could I control PD0 and PD1. I assume, default software has nothing to do with PD0 and PD1.

In my design, we are controlling opamp to switch on and off via PD0 and PD1. We are not using Analog switch or MUX.

Hi,

That's a good point. However, for development you should be able to hardwire both the PDs to "enabled" as I believe the PD feature is just to save power.

The software patch you are referring to seems like the right starting point, however I'm not sure why it's not working for you. In order to debug this we would need to dig into the code. Unfortunately, I don't have time to do that right now.

Post back if you have other question. I hope that help. Sorry for my lack of quick fixes!

Regards,

Evan
