    The following prepares to run the example with apbuart3 with UART TX output on GPIO35 and UART RX input on GPIO36. Connect a terminal to apbuart3 and set 115200 BAUD. When using GR716-BOARD, and the serial communication program Minicom, the following can be used: $ minicom -D /dev/ttyUSB2 -b 115200 Clock enable apbuart3.

  • Page 39: Spi Master Controller

    (SPIMCTRL) typically named spim0 and spim1. These four controllers operate independently. GR716-BOARD has SPI flash memory connected to the SPI memory controller spim0. The SPI controllers (spi0 and spi1) are not connected to any SPI slave devices on the GR716-BOARD.

  • Page 40: Spacewire

    The driver is general enough to work with most I2C peripherals such as temperature sensors, ADC, DAC, etc. 8.4.8.1. GR716-BOARD current measurement GR716-BOARD has two current measurement devices with I2C interface. The I2C bus of these devices are not directly connected to the GR716. However, the buses are available on the expansion headers which allows to connect the current measurement by fitting jumpers on the connector.

  • Page 41: Can

    The example assumes that the GR716 CAN external signals are connected to CAN transceivers. They could be connected to the same external CAN bus.
