Arduino UNO CAN bus shield connection

[Ree Wang]

Hi, DevZone,

I am trying connect nRF52480 Preview DK and an Arduino UNO CAN Bus shield.

What I did is:

1) I directly hook CAN Bus shield on the top of nRF52480 Preview DK. 

2) configure SPI PIN number corresponding to Arduino SPI PIN number.

    nrf_drv_spi_config_t spi_config = NRF_DRV_SPI_DEFAULT_CONFIG;
    spi_config.ss_pin   = SPI_SS_PIN;
    spi_config.miso_pin = SPI_MISO_PIN;
    spi_config.mosi_pin = SPI_MOSI_PIN;
    spi_config.sck_pin  = SPI_SCK_PIN;

    spi_config.irq_priority = APP_IRQ_PRIORITY_LOW;
    spi_config.orc          = 0xCC;
    spi_config.frequency    = NRF_DRV_SPI_FREQ_4M;
    spi_config.mode         = NRF_DRV_SPI_MODE_0;
    spi_config.bit_order    = NRF_DRV_SPI_BIT_ORDER_MSB_FIRST;

3) modify a CAN bus library...

I would like to know if 1) and 2) are correct?

Appreciate for any comments!

Hello,

It would be easier if you stuck to one of your previous cases, instead of creating new ones, such as one of these:

Did you try out the different modes, such as ovrebekk suggested in the first link?
