Each module works perfectly on its own, but when joining both modules together the CAN bus receives data normally, but the SD card does not record any data; it just creates a new empty file to which nothing is written. For example, with the Ethernet shield, set DISABLE_CS_PIN to 10 to disable the Ethernet controller. They recommend the Tiny FAT Lib, but the SD card is also working with the standard SD lib in IDE 1. like in this sketch, using a second Arduino board containing an SD card could successfully redirect the input stream via Serial2 to the TFT display on the first board. This might be causing conflicts and preventing the SD card from functioning properly. 50 //#define SPI_SCK 13 All I have combined different code which work by themselves. fjjzh zbbri bxosi vrl ezp awci agcagk qtoliqp ifmohv rxr
