BQ76PL455A-Q1: bq76PL455A-Q1 Example Code WriteReg/ReadReg() nDev_ID parameter?

Dick Lin

Part Number: BQ76PL455A-Q1

Hi,

What's the nDev_ID I should pass into both WriteReg() and ReadReg() function giving the fact that our design is two bq76PL455A-Q1 connect to separate MCU UART port without in a serial daisy-chain? Does the unique device identifier actually matter in this case?

nDev_ID = 0;
nSent = WriteReg(nDev_ID, 13, 0x10, 1, FRMWRT_SGL_NR); // set number of cells to 16

Thanks,

Dick

Hi Dick,

If you are using two different MCU's,both of the bottom devices should be "0".

For a different UART port, i would think it would be the same as long as the two have distince variables, etc. Both devices (and any daisy chaining) would start from device 0.

I haven't seen this setup before, but should be ok i think.

Hi David,
No, there is only 1 MCU. Two BQ76PL455A-Q1 connect to 1 MCU different UART port.

Thanks,
Dick

Hi Dick,

Thanks for the clarification.

Technically, i think it would work. Just make sure the code is sufficiently "separated" for the two to make sure they do not get mixed up.
