TuyaOS SPI (tkl_spi)

Demo: …/examples/driver_spi/example_driver_spi.c

Pattern

#include "tkl_spi.h"
#include "tal_log.h"

#define SPI_ID  0

void app_spi_send(const uint8_t *buf, uint32_t len)
{
    TUYA_SPI_BASE_CFG_T spi_cfg = {0};
    /* role/mode/freq/bitwidth — from demo */
    if (tkl_spi_init(SPI_ID, &spi_cfg) != OPRT_OK) {
        TAL_PR_ERR("spi init fail");
        return;
    }
    tkl_spi_send(SPI_ID, (uint8_t *)buf, len);
    tkl_spi_deinit(SPI_ID);
}

API

Function	Role
tkl_spi_init	open master
tkl_spi_send	TX
tkl_spi_deinit	close

Confirm CS/SCLK/MOSI/MISO pins and SPI id with the user. Full-duplex transfer may exist on some platforms — check vendor headers if needed.
