Hi,
I have a problem regarding the operation of the Piccolo I2C sending data.
I want to write some data out the I2C port to a digital resistor (AD5248) located on the PCB, and I'm really stuck. I am looking at the signals on a scope to verify what is send by the I2C, and I see that it works fine for the first byte transfer (a total of 3 bytes). I see the start, only 1 byte of data, followed by a stop.
The big problem is that nothing happens after that. Same routine, 1 clock, 1 data byte (the address byte), and nothing.
1) I'm using I2C interrupt.
2) I am using the FIFO transmit.
3) I put pull up resistors on the SDA and SCL (as TI request)
Please Advice what to do
Thanks,
