Async SPI port interface — implement these for your platform. More...

Detailed Description

Provides non-blocking, callback-based SPI transfers alongside the existing blocking API in syn_port_spi.h. The callback fires from ISR context.

** **

static void on_spi_done(uint8_t bus, SYN_Status result, void *ctx) {
    syn_port_spi_cs_deassert(0, cs_pin);
    // Process rx_buf
}

syn_port_spi_cs_assert(0, cs_pin);
SYN_SPI_Xfer xfer = {
    .bus       = 0,
    .tx_buf    = tx_data,
    .rx_buf    = rx_data,
    .len       = 256,
    .callback  = on_spi_done,
    .user_data = NULL,
};
syn_port_spi_xfer_async(&xfer);
