On the mega, the SPI pins are 50 - 53, that is what the SD card *should* be using. They could also use the ISCP pins, but that shield does not have ISCP so if it is not connected to the SPI pins, there will be no connection. - Topic: No SD Card being reportedYou Reply: [quote="sbirdranch"]Mine does not use the double row of pins on the mega.

- Topic: APC220 and pyserialYou Reply: I figured out how to get the APC220 working by translating a few forums.
I had to put ser.setRTS(0)
The problem now is that there is is significant lag when communicating. sometimes it might take a few seconds, sometimes nothing happens for a long time.
Is there any setting in these parameters that could make a difference?
(port=None, baudrate=9600, bytesize=EIGHTBITS, parity=PARITY_NONE, stopbits=STOPBITS_ONE, timeout=None, xonxoff=False, rtscts=False, writeTimeout=None, dsrdtr=False, interCharTimeout=None)
I am using baudrate 19200 right now.
From the arduino serial, I always get the communication with minimal delay, so once again, I think it might be a setting in pyserial that is causing this.
Thank You.
