Part Number:TMS320F28027
We're attempting to address an I2C slave device and have found that SCL is always high and SDA is always low right out of the boot state. We're running the code from flash and using the ControlSUITE templates.
At the very top of my main function, I added this code: while(1==1); So none of the rest of the code is doing anything and the CPU simply spins.
Then I hooked up a scope to GPIOs 32/33. I don't know much about I2C, honestly, but doesn't the I2C spec say that both signals are supposed to be high by default? I don't find any information in the data sheet regarding jumpers that might alter this behavior.
Thanks!
Mike
