hudakz 1:6f8ffb2c2dd7 2 * An example showing how to use the mbed CAN API:
hudakz 0:1b9561cd1c36 3 *
hudakz 3:87a128bca8f5 4 * Two affordable (about $2 on ebay) STM32F103C8T6 boards (20kB SRAM, 64kB Flash),
hudakz 1:6f8ffb2c2dd7 5 * (see [https://developer.mbed.org/users/hudakz/code/STM32F103C8T6_Hello/] for more details)
hudakz 0:1b9561cd1c36 6 * are connected to the same CAN bus via transceivers (MCP2551 or TJA1040, or etc.).
hudakz 0:1b9561cd1c36 7 * CAN transceivers are not part of NUCLEO boards, therefore must be added by you.
hudakz 0:1b9561cd1c36 8 * Remember also that CAN bus (even a short one) must be terminated with 120 Ohm resitors at both ends.
hudakz 1:6f8ffb2c2dd7 9 *
hudakz 0:1b9561cd1c36 10 *
hudakz 1:6f8ffb2c2dd7 11 * The same code is used for both mbed boards, but:
hudakz 0:1b9561cd1c36 12 * For board #1 compile the example without any change.
hudakz 3:87a128bca8f5 13 * For board #2 comment out line 21 before compiling
hudakz 0:1b9561cd1c36 14 *
hudakz 3:87a128bca8f5 15 * Once the binaries have been downloaded to the boards reset both boards at the same time.
