Tuyaopen/onchip Qspi

TuyaOpen On-Chip QSPI (master)

When NOT to use this skill

A catalogued QSPI LCD on the board goes through the display skill — board_register_hardware() + the tdd_display_qspi driver handle it. Use this on-chip skill only for a raw / custom QSPI device not in board-context.

On-chip — no Kconfig, no TDD

• Platform-provided. Do NOT write CONFIG_ENABLE_QSPI. No app_default.config change.
• No board_register_hardware(). Call tkl_qspi_* directly with TUYA_QSPI_NUM_<n>.
• Confirm which QSPI port + wire mode (1/2/4) + pins with the user; record as onchip:qspi<n> in used-peripherals.json.

Platform spec — read, don't hardcode

.tuyaopen/ide/platform.json → peripherals.qspi.spec: wireMode (1/2/4-wire support), role, type (flash/lcd), mode, freq range, and ports[].pinGroups (CLK/CS/IO0–3 pins). Read these for the chosen port instead of assuming.

Init

#include "tal_api.h"
#include "tkl_qspi.h"

#define QSPI_PORT   TUYA_QSPI_NUM_0

static void qspi_event_cb(TUYA_QSPI_NUM_E port, TUYA_QSPI_IRQ_EVT_E event)
{
    if (event == TUYA_QSPI_EVENT_TX) { /* TX complete */ }
}

void app_qspi_init(uint32_t freq_hz)
{
    TUYA_QSPI_BASE_CFG_T cfg = {
        .role           = TUYA_QSPI_ROLE_MASTER,
        .mode           = TUYA_QSPI_MODE0,          /* MODE0..3 */
        .type           = TUYA_QSPI_TYPE_LCD,       /* or TUYA_QSPI_TYPE_FLASH */
        .freq_hz        = freq_hz,
        .use_dma        = TRUE,
        .dma_data_lines = TUYA_QSPI_4WIRE,          /* 1WIRE / 2WIRE / 4WIRE */
    };
    tkl_qspi_init(QSPI_PORT, &cfg);
    tkl_qspi_irq_init(QSPI_PORT, qspi_event_cb);
    tkl_qspi_irq_enable(QSPI_PORT);
}

Command + bulk data

A QSPI transaction is a TUYA_QSPI_CMD_T (per-phase wire width) followed by an optional bulk tkl_qspi_send. Note the SDK spells the function tkl_qspi_comand (one m) — use it verbatim.

void app_qspi_write(const uint8_t *frame, uint32_t len)
{
    TUYA_QSPI_CMD_T cmd = {0};
    cmd.op         = TUYA_QSPI_WRITE;       /* or TUYA_QSPI_READ */
    cmd.cmd[0]     = 0x32; cmd.cmd_size = 1;
    cmd.cmd_lines  = TUYA_QSPI_1WIRE;       /* command on 1 line */
    cmd.addr[0]    = 0x00; cmd.addr[1] = 0x2C; cmd.addr_size = 2;
    cmd.addr_lines = TUYA_QSPI_1WIRE;
    cmd.data_lines = TUYA_QSPI_4WIRE;       /* payload on 4 lines */
    cmd.dummy_cycle = 0;

    tkl_qspi_comand(QSPI_PORT, &cmd);       /* SDK spelling: no second 'm' */
    tkl_qspi_send(QSPI_PORT, (void *)frame, len);
}

API Reference

Wire modes: TUYA_QSPI_1WIRE (std SPI) / TUYA_QSPI_2WIRE (dual) / TUYA_QSPI_4WIRE (quad).
