![]() Do NOT #define SOFTWARE_SPI or MEGA_SOFT_SPI in the library. Verkauf durch MoLiSmart, Lieferung durch Amazon Fulfillment. 10,99 10, 99 Erhalte es bis Donnerstag, 7. So Ive found that it works with the pin 10 and 11 on a MEGA. Dieser Artikel: DSD TECH HM-10 Bluetooth 4.0 BLE iBeacon UART Modul mit 4 PIN Base Board für Arduino UNO R3 Mega 2560 Nano. ![]() Use the standard SD library (not the Adafruit fork). A lot of tuto explain with the Pin 2 and 3 but it doesnt work with a arduino MEGA. The onls difference is that they use a UNO instead of the MEGA I use. I use the mcp2515.h library, the standard test programm and also the standard connections. Accessing the SD card is possible with the addition of some jumper wires, but difficult due to the fact that the shield obscures the ICSP header where these wires must be connected.Īdd jumper wire from pin 11 on shield to ICSP pin 4.Īdd jumper wire from pin 12 to ICSP pin 1.Īdd jumper wire from pin 13 to ICSP pin 3. Hallo zusammen I tried to conntect two Arduino Mega with two joy-it MCP 2515 can modules. The RTC is compatible (when using latest library). It comes with more memory space and I/O pins as compared to other boards available in the market. This is difficult due to the shield obscuring the ICSP header and is not much recommended.Įdit the file utility/Sd2Card.h in the default Arduino SD library, changing line 42 to read " #define MEGA_SOFT_SPI 1" (default is 0).Īdd jumper wire from SDA on shield to pin 20 on Mega board.Īdd jumper wire from SCL on shield to pin 21 on Mega board.įor the SD card, the following may be tried, in decreasing order of recommendation: Arduino Mega 2560 is a Microcontroller board based on Atmega2560. Use the Adafruit SD library, specifying pin 10 for chip select, 11 for MOSI, 12 for MISO and 13 for SCK.Įdit the file utility/Sd2Card.h in the default Arduino SD library, adding the line " #define SOFTWARE_SPI" (not MEGA_SOFT_SPI) at the top.Īdd jumper wires from pin 11 on the shield to ICSP pin 4 on the board (on the 6-pin header), pin 12 to ICSP-1 and pin 13 to ICSP-3, then use the standard library in its default state (no SOFTWARE_SPI). ![]() For the SD card, the following may be tried, in decreasing order of recommendation: This shield may work with other boards with some additional steps: Incompatible or Partially-Compatible Boards ![]()
