ESP32-C3， esp-idf 4.3.5，控制CH623。GPIO14控制SPI_CS，GPIO15控制SPI_SCK，GPIO16控制SPI_MOSI,GPIO17控制SPI_MISO，GPIO4控制NRST，GPIO12控制IRQ。写一个读取身份证信息的程序

好的，以下是基于ESP32-C3和esp-idf 4.3.5的读取身份证信息的程序：

#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/gpio.h"
#include "driver/spi_master.h"

#define PIN_CS   GPIO_NUM_14
#define PIN_SCK  GPIO_NUM_15
#define PIN_MOSI GPIO_NUM_16
#define PIN_MISO GPIO_NUM_17
#define PIN_NRST GPIO_NUM_4
#define PIN_IRQ  GPIO_NUM_12

#define CMD_READ_DATA 0x30

static spi_device_handle_t spi;

static void spi_init() {
    esp_err_t ret;
    spi_bus_config_t buscfg = {
        .mosi_io_num = PIN_MOSI,
        .miso_io_num = PIN_MISO,
        .sclk_io_num = PIN_SCK,
        .quadwp_io_num = -1,
        .quadhd_io_num = -1,
        .max_transfer_sz = 4096,
    };
    spi_device_interface_config_t devcfg = {
        .clock_speed_hz = 1000000,
        .mode = 0,
        .spics_io_num = PIN_CS,
        .queue_size = 1,
    };
    ret = spi_bus_initialize(SPI2_HOST, &buscfg, 1);
    ESP_ERROR_CHECK(ret);
    ret = spi_bus_add_device(SPI2_HOST, &devcfg, &spi);
    ESP_ERROR_CHECK(ret);
}

static void ch623_reset() {
    gpio_set_direction(PIN_NRST, GPIO_MODE_OUTPUT);
    gpio_set_level(PIN_NRST, 0);
    vTaskDelay(pdMS_TO_TICKS(1));
    gpio_set_level(PIN_NRST, 1);
    vTaskDelay(pdMS_TO_TICKS(20));
}

static void ch623_send_cmd(uint8_t cmd) {
    uint8_t txbuf[2] = {cmd, 0};
    uint8_t rxbuf[2] = {0};
    spi_transaction_t t = {
        .length = 16,
        .tx_buffer = txbuf,
        .rx_buffer = rxbuf,
    };
    spi_device_polling_transmit(spi, &t);
}

static void ch623_read_data(uint8_t *buf, size_t len) {
    uint8_t txbuf[len + 1];
    uint8_t rxbuf[len + 1];
    txbuf[0] = CMD_READ_DATA;
    memset(txbuf + 1, 0, len);
    spi_transaction_t t = {
        .length = (len + 1) * 8,
        .tx_buffer = txbuf,
        .rx_buffer = rxbuf,
    };
    spi_device_polling_transmit(spi, &t);
    memcpy(buf, rxbuf + 1, len);
}

void app_main() {
    gpio_set_direction(PIN_IRQ, GPIO_MODE_INPUT);
    spi_init();
    ch623_reset();
    ch623_send_cmd(0x07);
    ch623_send_cmd(0x08);
    uint8_t buf[256];
    ch623_read_data(buf, 256);
    for (int i = 0; i < 256; i++) {
        printf("%02x ", buf[i]);
        if ((i + 1) % 16 == 0) {
            printf("\n");
        }
    }
}

这个程序的基本流程如下：

1. 初始化SPI总线和SPI设备。
2. 复位CH623芯片。
3. 发送0x07和0x08两个命令，初始化CH623芯片。
4. 发送0x30命令，读取身份证信息。
5. 将读取到的信息打印出来。

这个程序的具体实现细节，可以参考注释和CH623芯片的数据手册。
