Other Parts Discussed in Thread: TPS65917EVM
I am currently testing TPS65917EVM.
I have two questions.
First, which pin should I use for Vref? (IO_VIN)
Second, I have connected I2C SCL line to J7, I2C SDA line to J10, connected power supply to P16 and connected USB to MPS430.
I used 0x48 for my slave device address and 0x23 for my register address.
However, It seems like Acknowledge isn't generated by the slave and I have no idea why.
Any IDEA is appreciated.
I will look forward to your reply.
