setSOC1Thresholds(SOCI_SET, SOCI_CLR) fail

Open Kabron287 opened this issue 4 years ago • 2 comments

Hi there! I arize the problem again. This problem still exists in both libraris: SparkFun_BQ27441_Arduino_Library and Battery_Babysitter To reproduce, just run BQ27441_GPOUT_BAT_LOW.ino You'll see that SOC1SetThreshold() funtion allways return 64(0x40).

I observe this on three bq27441 chips.

My uC ATSAMD51 in WIO Terminal.

Update Just test it with Arduino Pro Micro with the same result. SOC1SetThreshold() funtion allways return 64.

the datasheet indicates that 66us is needed between i2c transactions. On faster processors this does not seem to be met with this library.

add delayMicroseconds(66); before the return in i2cWriteBytes and i2cReadBytes.

that fixed the problem for me.
