Code Get Stuck

Hi,I am using STM32L072 LoRa discovery kit and enabled UART with DMA. Some times my code gets stuck in HAL_UART_Receive_DMA( ....) function at the line SET_BIT(huart->Instance->CR3, USART_CR3_EIE);This is called at the begining of the code. It wont r...

Sub-GHz and ADC DMA integration errors

Hi All,I'm using STM32WL55JC board which include Sub-GHz, ADC and DMA peripherals (and many more of course)I run "ping pong" example to create Sub-GHz communication sucssfully, also run "ADC_SingleConversion_TriggerTimer_DMA" and changed to circular ...

Resolved! About Data transmit with Usart1 using DMA

Hi.I am using STM32WL55.I set USART1 with DMA tx and DMA rx.I tried to transmit some data as follows.  printf("[*] Program Ver 0.2.0.0\r\n");  printf("\r\n");  printf("Net> ");"[*] Program Ver 0.2.0.0\r\n" and "\r\n" are transmitted.but "Net> " is di...

Resolved! How to use ADC sensor with Ping Pong Application

Hello everyone, I am trying to read adc value from microphone. I am using FFT to get 100 Hz to 2 kHz or more to detect tone. In my project, I can use dma for get adc value and then I use DSP CMSIS. I can do this with my new workspace (with out anythi...

stm32wl55jc adjust adc dma sample rate for microphone

I am using stm32wl55jc1. I want to use accelerometer at 50khz and microphone at 2khz (2048). I am trying to make fft. With pooling adc method, I can do that easily. with 500 micro second delay. for(int i=0;i<128;i++) { microSecond=micros(); HAL_ADC_P...

Hi, I'm trying to transmit information between two NucleoWL55JC1 boards using LoRa modulation, i.e only the SUBGHZ_PHY layer. I want to set up the peripherals and middleware with CubeMX and use the HAL SUBGHZ functions in the code section.

Unluckily, I haven't found indications as to which of this functions to use for a basic transmit/receive application. In the HAL documentation and inside the stm32wlxx_hal_subghz.c file the functions are described independently but there is no cont...
