esp32C2串口不够用(esp_log_set_vprintf)使用任意IO模拟串口解决

#define GPIO_OUTPUT_IO_0    10
#define GPIO_OUTPUT_PIN_SEL ((1ULL << GPIO_OUTPUT_IO_0))

// 模拟串口0初始化
void iouart0_init(void)
{
   
    gpio_config_t io_conf = {
   };
    // disable interrupt
    io_conf.intr_type = GPIO_INTR_DISABLE;
    // set as output mode
    io_conf.mode = GPIO_MODE_OUTPUT;
    // bit mask of the pins that you want to set,e.g.GPIO18/19
    io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;
    // disable pull-down mode
    io_conf.pull_down_en = 0;
    // disable pull-up mode
    io_conf.pull_up_en = 0
