【已解决】关于axyu模组的adc使用
Posted: 2023年 Jul 23日 08:53
求助我该如何初始化axyu模组的adc脚，具体是哪个adc的通道几。我使用的是下面这个来初始化和读取数据 显示报错 -4不支持。
Code: Select all
#define ADC_CHANNEL 1
STATIC TUYA_ADC_BASE_CFG_T sg_adc_cfg = {
.ch_list.data = 1 << ADC_CHANNEL,
.ch_nums = 1, // adc Number of channel lists
.width = 12,
.mode = TUYA_ADC_CONTINUOUS,
.type = TUYA_ADC_EXTERNAL_SAMPLE_VOL,
.conv_cnt = 1,
};
STATIC VOID_T app_bat_task(VOID_T *args)
{
OPERATE_RET rt = OPRT_OK;
INT32_T adc_value = 0;
/* ADC 0 channel 2 init */
while(1){
tal_system_sleep(2000);
TUYA_CALL_ERR_LOG(tkl_adc_read_single_channel(TUYA_ADC_NUM_0, ADC_CHANNEL, &adc_value));
TAL_PR_DEBUG("ADC%d value = %d", TUYA_ADC_NUM_0, adc_value);}
}
VOID_T app_bat_init(TUYA_GPIO_NUM_E pin_id)
{
// sg_bat_pin_id=pin_id;
OPERATE_RET rt = OPRT_OK;
/* init bat gpio
TUYA_GPIO_BASE_CFG_T key_cfg = {
.mode = TUYA_GPIO_PULLUP,
.direct = TUYA_GPIO_INPUT,
.level = TUYA_GPIO_LEVEL_HIGH};
TUYA_CALL_ERR_LOG(tkl_gpio_init(pin_id, &key_cfg));
sg_bat_pin_id = pin_id;*/
TUYA_CALL_ERR_LOG( tkl_adc_init(TUYA_ADC_NUM_0, &sg_adc_cfg));
THREAD_HANDLE bat_task_handle;
THREAD_CFG_T thread_cfg = {
.thrdname = "bat_task",
.priority = THREAD_PRIO_6,
.stackDepth = 2048
};
TUYA_CALL_ERR_LOG(tal_thread_create_and_start(&bat_task_handle, NULL, NULL, app_bat_task, NULL, &thread_cfg));
}
