ESP-32 S3 Cannot initialize multiple spi devices (host_id not initialized)

Hi,
When i'm trying to initialize multiple devices, i get the error:
spi_master: spi_master_init_driver(200): host_id not initialized
ESP_ERROR_CHECK failed: esp_err_t 0x103 (ESP_ERR_INVALID_STATE) at 0x4037d06c
file: "src/board/board_spi.cpp" line 35
func: void NFC_SPI_Init()
expression: ret


Unsure what's wrong in my code, i tried modifying the host values but i still get an error or a black screen / rfid reader not working,
any help might be appreciated:

Why did you comment out spi_bus_initialize?

Because it's initialized in the lgfx config and i'm unsure if i should initialize it twice, should I ?

If I read your code correctly, it's not: you're using SPI2_HOST there, not SPI3_HOST. You either need to move your devices to the same SPI host (if your devices share SCK/MISO/MOSI lines) or initialize each SPI host separately (if they do not).

I"m unsure about a second initialization, when i uncomment the spi_bus initialize with this code:

Code: Select all

void NFC_SPI_Init(void) {
   
    esp_err_t ret;

    spi_bus_config_t spiBusConfig;

    spiBusConfig.miso_io_num = NFC_SPI_MISO_PIN;
    spiBusConfig.mosi_io_num = NFC_SPI_MOSI_PIN;
    spiBusConfig.sclk_io_num = NFC_SPI_SCLK_PIN;
    spiBusConfig.quadwp_io_num = -1,
    spiBusConfig.quadhd_io_num = -1,
    spiBusConfig.max_transfer_sz = 64*8;
    
    

    spi_device_interface_config_t spiDeviceConfig;

    spiDeviceConfig.clock_speed_hz = SPI_MASTER_FREQ_10M;
    spiDeviceConfig.mode = 0;
    spiDeviceConfig.spics_io_num = NFC_SPI_CS_PIN;
    spiDeviceConfig.queue_size = 7;
   

    ret = spi_bus_initialize(SPI3_HOST, &spiBusConfig, SPI_DMA_CH_AUTO); 
    ESP_ERROR_CHECK(ret);
    ret = spi_bus_add_device(SPI3_HOST, &spiDeviceConfig, &s_spiHandle);
    ESP_ERROR_CHECK(ret);

    gpio_pad_select_gpio(NFC_SPI_CS_PIN);
    gpio_set_direction(NFC_SPI_CS_PIN, GPIO_MODE_OUTPUT);
}

class LGFX : public lgfx::LGFX_Device
{
    lgfx::Panel_ILI9488  _panel_instance;
    lgfx::Bus_SPI       _bus_instance;
    lgfx::Light_PWM     _light_instance;
    lgfx::Touch_GT911   _touch_instance;
  public:
    LGFX(void)
    {
      {
        auto cfg = _bus_instance.config();
        cfg.spi_host         = SPI3_HOST; 
        cfg.spi_mode         = 0;
        cfg.freq_write       = 40000000;
        cfg.freq_read        = 16000000;
        cfg.spi_3wire        = true;
        cfg.use_lock         = true;
        cfg.dma_channel      = SPI_DMA_CH_AUTO;
        cfg.pin_sclk         = 18;
        cfg.pin_mosi         = 13;
        cfg.pin_miso         = 19;
        cfg.pin_dc           = 16;

        _bus_instance.config(cfg);
        _panel_instance.setBus(&_bus_instance);
      }
I get the error spi: spi_bus_initialize(756): SPI bus already initialized.
ESP_ERROR_CHECK failed: esp_err_t 0x103 (ESP_ERR_INVALID_STATE) at 0x4037d06c
file: "src/board/board_spi.cpp" line 33
func: void NFC_SPI_Init()
expression: ret

abort() was called at PC 0x4037d06f on core 1

When i comment it, there are no error message but nothing is displayed and when i comment the NFC_Init() func the display is working fine. I'm wrong somewhere with the bus usage but don't know where

I think you need to track down where SPI2 is initialized, then. It doesn't appear to happen anywhere in the code you posted. EDIT: SPI2 instead of SPI3.

You mean by declaring a spiclass and storing it somewhere ? I effectively didn't try that but that wouldn't be compatible with the way of using the lgfx lib right ?

No, I mean by going through all your code and see where it initializes (or even touches) the SPI2 host. Something seems to be doing that, making your init fail as the SPI2 host already is inited. EDIT: I meant SPI2, not SPI3.
