VREFBUF not working on STM32WLE5JC
Hello everyone,
I'm trying to set up VREFBUF as an internal reference at 2.5V, but the configuration isn't working. I've seen there were issues with this (VREFBUF Enable Problem - STMicroelectronics Community), but even after rearranging the function 'HAL_SYSCFG_VREFBUF_HighImpedanceConfig(SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE);', it doesn't work properly. I'm using the STM32WLE5JC on the 'Lora E5 mini' development board. Here is my code:
void HAL_MspInit(void)
{
/* USER CODE BEGIN MspInit 0 */
HAL_SYSCFG_VREFBUF_HighImpedanceConfig(SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE);
/* USER CODE END MspInit 0 */
/* System interrupt init*/
/** Configure the internal voltage reference buffer voltage scale
*/
HAL_SYSCFG_VREFBUF_VoltageScalingConfig(SYSCFG_VREFBUF_VOLTAGE_SCALE1);
/** Enable the Internal Voltage Reference buffer
*/
HAL_SYSCFG_EnableVREFBUF();
/** Configure the internal voltage reference buffer high impedance mode
*/
HAL_SYSCFG_VREFBUF_HighImpedanceConfig(SYSCFG_VREFBUF_HIGH_IMPEDANCE_DISABLE);
/* USER CODE BEGIN MspInit 1 */
/* USER CODE END MspInit 1 */
}
Any idea what I can do?"
