Hi,
I have connected my AD2 to a BMI160 breakout board (https://www.amazon.com/6-axis-BMI160-Gravity-Accelerometer-Electronic/dp/B07RYG99F5).
My connections are as follows:
V+ --> VIN of breakout
GND -> GND of breakout
SDA -> DIO 1 -> SDA of breakout
SCL -> DIO 0 -> SCL of breakout
SA0 of breakout -> GND
I have verified the above connection works fine to communicate with BMI160.
But when I use AD2 to communicate with it, I see the "I2C bus error. Verify the singal pullups."
Following is my script:
// Pmod GYRO - BMI160
const adr = 0x68;
if(Clear()!=true) return "I2C bus error. Check the pull-ups.";
if(Write(adr)!=true) return "Device NAK";
if(Read(adr, 0x00, 1) != 0xD1) return "Device ID mismatch";
Any help is appreciated. You can see in page 102 of (https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmi160-ds000.pdf) , it already has external pull-ups.
What am I missing here?
