Other Parts Discussed in Thread: MSP430FR6989, LDC0851, MSP430FW427, MSP430FR5989
I am developing a water meter with NB-IoT modem. So far I can see following solutions from TI.
- MSP430G2211 (LC + discrete logic + dual comparators on chip, based upon slaa138a) to dected four phase as a generic flow meter sensor.
- MSP430FR6989 ESI flow meter design
- LDC0851 for flow meter
Since this product is cost-driven, slaa138a is preferred, but I can not find its source code. Where can I find it?
MSP430FR6989 is expensive than G2211. Is there any low pin count MSP430 with ESI on chip, just small enough to use as a sensor output
LDC0851, I can not find a proper design for flow meter, since its design is a little different from MSP430G2211. with only one channel.
Does anyone have experiences on these designs?
