Will SD Card library interfere with a SoftwareSerial port?


I have a system where a number of devices are sending messages to my device via XBEE. The XBEE radio is connected to pins 10 and 11 and a SoftwareSerial is created to communicate with it. I save the messages to SD card as they arrive. However, for the duration of time that I am communicating with the SD card, will incoming messages be destroyed?

If you are using an Uno, pins 10 and 11 are SPI pins and can't be used for software serial if you are using a SPI device.

The SD card is a SPI device.

You can use software serial on other non SPI pins and the SD will not interfere. SPI pins are 10, 11, 12, and 13 on Uno.

Thank you, that's exactly what I needed to know :)
