Hello, I am trying to connect an arduino nano to a mma8451 accelerometer this week. However, it stopped after I uploaded the official example (maybe stopped at recognizing the sensor). This example successfully functioned last year. I have swapped different boards, wires, sensors, and pins. Does anyone know what might cause this happen? Or is there anyway I can test the functionality of the sensor?
In this library .cpp, this line (84) will stop everything if it equals 1.
while (readRegister8(MMA8451_REG_CTRL_REG2) & 0x40)
;
The datasheet says MMA8451_REG_CTRL_REG2 does not exist, but CTRL_REG2 does, and further says:
Modification of this register’s contents can only occur when device is STANDBY mode except CTRL_REG1 ACTIVE bit and CTRL_REG2 RST bit.
Whatever that means. Maybe your have an out-dated library or sketch?
Maybe, inside a copy of the .cpp, you can print the contents of the ...REG2?
Maybe soldering the header pins to the sensor module will help.
