Hello, I’m using a C library that sends raw LoRa data esp32-lora-library , the library works fine when i use it with an ESP32 dev board + SX127X , but when i include it inside the wireless stick lite project, it keeps throwing “E (313) spi: spi_bus_initialize(628): SPI bus already initialized.”
i’m using ESP-IDF and this is the pin configurations for the Heltech board:
#define CONFIG_CS_GPIO 18
#define CONFIG_RST_GPIO 14
#define CONFIG_MISO_GPIO 19
#define CONFIG_MOSI_GPIO 27
#define CONFIG_SCK_GPIO 5
The error comes from the initialization function’s lines which try to initialize the spi and register it.
int lora_init(void)
{
esp_err_t ret;
/*
* Configure CPU hardware to communicate with the radio chip
*/
gpio_pad_select_gpio(CONFIG_RST_GPIO);
gpio_set_direction(CONFIG_RST_GPIO, GPIO_MODE_OUTPUT);
gpio_pad_select_gpio(CONFIG_CS_GPIO);
gpio_set_direction(CONFIG_CS_GPIO, GPIO_MODE_OUTPUT);
spi_bus_config_t bus = {
.miso_io_num = CONFIG_MISO_GPIO,
.mosi_io_num = CONFIG_MOSI_GPIO,
.sclk_io_num = CONFIG_SCK_GPIO,
.quadwp_io_num = -1,
.quadhd_io_num = -1,
.max_transfer_sz = 0
};
ret = spi_bus_initialize(VSPI_HOST, &bus, 0);
assert(ret == ESP_OK);
spi_device_interface_config_t dev = {
.clock_speed_hz = 9000000,
.mode = 0,
.spics_io_num = -1,
.queue_size = 1,
.flags = 0,
.pre_cb = NULL
};
ret = spi_bus_add_device(VSPI_HOST, &dev, &__spi);
assert(ret == ESP_OK);
/*
* Perform hardware reset.
*/
lora_reset();
/*
* Check version.
*/
uint8_t version;
uint8_t i = 0;
while(i++ < TIMEOUT_RESET) {
version = lora_read_reg(REG_VERSION);
if(version == 0x12) break;
vTaskDelay(2);
}
assert(i <= TIMEOUT_RESET + 1); // at the end of the loop above, the max value i can reach is TIMEOUT_RESET + 1
/*
* Default configuration.
*/
lora_sleep();
lora_write_reg(REG_FIFO_RX_BASE_ADDR, 0);
lora_write_reg(REG_FIFO_TX_BASE_ADDR, 0);
lora_write_reg(REG_LNA, lora_read_reg(REG_LNA) | 0x03);
lora_write_reg(REG_MODEM_CONFIG_3, 0x04);
lora_set_tx_power(17);
lora_idle();
return 1;
}
I’ve no idea where else the spi get initialized, and the library is working with other boards!!
