STM32F407 USART6 DMA not receiving data

I have configured 2 UARTS both are configured to using HAL_UARTEx_ReceiveToIdle_DMA.My init functions:HAL_UARTEx_ReceiveToIdle_DMA(&huart3,aRxBuffer, RXBUFFERSIZE);   __HAL_DMA_DISABLE_IT(&hdma_usart3_rx,DMA_IT_HT);       HAL_UARTEx_ReceiveToId...

Power supply without regulator

Hello,I am currently working on my end of year project. I first realized my project under a development kit then now I realize the PCB.I am currently facing a problem. I have an STM32L073RZ which I must supply. As a power supply, I have a Li-SOCl2 ac...

I have a STM32H7 project and want to use the DMA for peripheral data transfer with an external static DMAREADY input

When using an EXTI input to trigger a DMA request, there is only the possibility to trigger on falling or rising edged of the input. But my peripheral has only an output which is active when data are ready for read or write. This output is static and...

FDCAN Tranceiver on STM32G0B

Hi all,I have a CAN 2.0 network up and running with a F407 and some F103. I added a board with a G0B (fdcan). I couldn't get my hands on a FDCAN-tranceiver. I tried to get it working in classic mode (from repository example) with a CAN2.0 tranceiver....

Is there an API that allows you to send data greater than 8 bytes through the CAN communication protocol?

I would like to build an application on an STM32 microcontroller (the one integrated in the NUCLEO-L432KC) that allows to transmit a message of 192 bytes or more if possible on CAN BUS.At first, I was thinking of a mechanism that in the transmission ...

STM32F407VGT6 PWM Input mode and PWM Generation mode

Hi everyone!In my project, I use TIM2, TIM3, TIM4, TIM5, in each Timer module I choose PWM Input on CH1, and PWM Generation on CH3 function. My goal is to generate PWM pulse at channel 3 and feed back to PWM Input on CH1 to measure Duty cycle and fre...

STM32H7 FMC SDSR busy bit is not documented or doesn't exist?

I've come across the following code in system_stm32h7xx.c, present in all example projects in STM32CubeH7 FMC_Bank5_6_R->SDCMR = 0x00000009; tmpreg = FMC_Bank5_6_R->SDSR & 0x00000020; while((tmpreg != 0) && (timeout-- > 0)) { tmpreg = FM...

I want to make an if conditional that BLE is paired (connected) or not. I mean I want to build a code "if BLE connected, do something." What BLE API should I use?

UART_FLAG_TXE is not set while a lots of ADC interrupt are issued.

Hi,I am using 4 ADC channel to read MIC circuit with STM32G030C8T6I am using ADC interrupt service to read ADCsI set ADC as follow:Clock Prescaler: Async clock mode divided by 32 Scan conversion Mode: enableContinuous conversion mode: enableADC_regul...
