Hi, I ported PCA9865 functions over. I am trying to access it on the STM32F4Discovery. I am getting timeouts on both B6,B7 and B8,B9 pins. On B6,B7 I get
INTERNAL ERROR: Timeout on I2C Write BUSY
INTERNAL ERROR: Timeout on I2C Write SB
INTERNAL ERROR: Timeout on I2C Write Transmit Mode 2
INTERNAL ERROR: Timeout on I2C Write Transmit
INTERNAL ERROR: Timeout on I2C Write Transmit
at line 5 col 48
this.i2c.writeTo(this.a, [PCA9685_MODE1, 0x0]);
on B8,B9
INTERNAL ERROR: Timeout on I2C Write Transmit Mode 2
INTERNAL ERROR: Timeout on I2C Write Transmit
INTERNAL ERROR: Timeout on I2C Write Transmit
at line 5 col 48
this.i2c.writeTo(this.a, [PCA9685_MODE1, 0x0]);
Any advice on debugging?
