I have encountered an issue with the programmable xbee's pin 7. Initially I was attempting to use I2C and found the communication was not behaving as expected. I attached SDA (Pin 7) to an oscilloscope and found logic low was only reaching 0.85 volts, not the ~0 volts that I expected. The trace on the board goes directly between the two SDA pins on the devices and is pulled up with a 10K resistor to Vcc (3v). Out of curiosity, I removed I2C in CodeWarrior and set Pin 7 to a GPIO output without a pull. Then in the beginning of main I use gpio_set(PIN7, 0) to set the pin low and found the same results. The pin was only going down to 0.85 volts. Is there some setting or conflict that could cause this symptom?
Thanks in advance!
