Part Number: MSP430FR6989 Other Parts Discussed in Thread: MSP-EXP430FR6989
Hi all,
I tried to test firmware TIDM-3LC-WATERMTR with kit MSP-EXP430FR6989. But when i tried to test, the signal from ESICH0, ESICH1, ESICH2 was very strange. I use coil 100uH…
I see not only the calibration has something to do. As well explained in: https://e2e.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/942282/tidm-lc-watermtr-tidm-lc-watermtr-the-magnet-is-near-the-lc-sensor-problem
"To minimize…
Hi Juan,
The only reference design for water flow meters with MSP430FR6989 can be seen at https://www.ti.com/tool/TIDM-LC-WATERMTR . Is this what you are looking for?

Hi Kai
I can't find the slaa138a in the on line. What I have saw before are two solutions in TI:1. MSP430FW427 http://www.ti.com/tool/TIDM-WATERMETER-LCSENSOR
This solution will be low cost than MSP430FR6989 with the SIF module but have less performance…
Sebastian,
Sorry for my delay. The issue with this method is that TIDM-LC-WATERMTR uses a USB HID bridge to communicate with the GUI. On the FR6989 launchpad, this is using a USB serial port and does not support HID. You could likely use the TIDA…
Balint,
The ESI interrupts are shown in the MSP430FR6989 users guide in table 37-7.

Also, the TI Design below shows the software flow in section 5 where Q6 flag is checked. You should be able to use this…
Hi,
Based on your description, you are using PCB coil as the inductors in the TIDM-LC-WATERMTR . The PCB coil can create a stronger electromagnetic field than the regular one. However when you have two PCB coils on your board, especially when you placed closely…

Hello, I'm testing a device that uses an ESI module to read rotation disk from a watermeter. I'm not the author of the device. We have some problems with losing synchronization…

I download a FR6989 LC ESI design code,in the software, there has a LC_Threshold_TSM_CAL value
so how should i set the LC_Threshold_TSM_CAL value ? what is the rule to…
Hi Robert,
I've had to say 'oops' many times myself, I certainly understand, especially when doing research. I read that ADI App Note, they had some detailed designs for sure.
So, back to the TI design, I'm wondering if the WATERMTR Ref…
