MSP430FR6989: ESI channel will be error triggered after restart

jianyang lin

The device is connected to the sensor to test, and the channel will be error triggered after restart. Using the TSM_Auto_cal() generated by FlowESIGUI software (), the ESITSMx value is different each restart.

Then I tried to write directly with the ESITSMx generated by TSM_Auto_cal (), but it would cause the channel to be error triggered. For example, if I use 0, 1 and 2 channels, the 1 and 2 channels will be error triggered.

How to solve this problem?

Hi Jianyang,
Where do you get the FlowESIGUI? I don't think it is provided by TI. If you have any software issue, please refer to the ESI flow meter example code. The code is here. www.ti.com/.../tidc583. Please try this one.

Best regards,

why say FlowESIGUI is not provided by TI. Can you try to test?

Hi Jianyang,
1. This device needs to calibrate the TSM and DAC value each time it power up. When you restart the MCU, you need to run the calibration process again.
2. The calibration data(TSM & DAC) may be slightly different each time.
3. How do you directly write to the TSM? Can you share your code?

Best regards,
