Question

How can I convert additional regular conversion?

I'm using MCSDK_v5.4.3 but I don't know how can I convert additional ADC channel.

Below is ADC initialization code. added channel 9 and 10.

But I can't convert channel 9 and 10.

How can I convert ch.9 & 10.

Some sample code will very helpful to me.

Thanks

Are you saying this code converts channels 2 and 8 just fine but doesn't convert 9 and 10? Seems odd.

Make sure you're initializing the pins for channels 9/10.

I added initializing code for 9 & 10 and pin assignment also as below.

void HAL_ADC_MspInit(ADC_HandleTypeDef* hadc)

{

 GPIO_InitTypeDef GPIO_InitStruct = {0};

 if(hadc->Instance==ADC1)

 {

  __HAL_RCC_ADC1_CLK_ENABLE();

  __HAL_RCC_GPIOC_CLK_ENABLE();

  __HAL_RCC_GPIOA_CLK_ENABLE();

  GPIO_InitStruct.Pin = M1_CURR_AMPL_W_Pin|M1_CURR_AMPL_V_Pin|M1_TEMPERATURE_Pin|ADC_9_Pin;

  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;

  GPIO_InitStruct.Pull = GPIO_NOPULL;

  HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);

  GPIO_InitStruct.Pin = M1_CURR_AMPL_U_Pin|M1_BUS_VOLTAGE_Pin|ADC_10_Pin;

  GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;

  GPIO_InitStruct.Pull = GPIO_NOPULL;

  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

 }

}

What I want to ask is how can I use below functions related regular conversion.

such as

uint8_t RCM_RegisterRegConv(RegConv_t * regConv);

uint8_t RCM_RegisterRegConv_WithCB (RegConv_t * regConv, RCM_exec_cb_t fctCB, void *data);

uint16_t RCM_ExecRegularConv (uint8_t handle);

bool RCM_RequestUserConv(uint8_t handle);

uint16_t RCM_GetUserConv(void);

void RCM_ExecUserConv (void);

RCM_UserConvState_t RCM_GetUserConvState(void);

Thanks
