Problem receiving CAN message with Interrupt callback

I´ve a problem receiving a CAN message with interrupt. When I poll with the same settings the message is received correctly.I´m using STM32CubeIDE with a STM32F103RBT6.When I poll:if (HAL_CAN_GetRxFifoFillLevel (&hcan, CAN_RX_FIFO0) > 0){     HAL_CA...

HI. I have a STEVAL-IDB008V1M development board. I am trying to make a BLE scanner, to read data from 15 BLE beacons. I cannot find much help and when using the GUI, It comes up with message "No device detected", and no FW, etc. Please help. I am upset,

Please help me in this regard. I have to have a prototype ready by Friday.

How should I use argument "Channel" in function: HAL_SDADC_InjectedGetValue(SDADC_HandleTypeDef *hsdadc, uint32_t* Channel)

Hi!I'm trying to make 16-bit ADC measurement works but I have some trouble understanding the argument Channel. First I have these SD-ADC channels.SDADC1 have:IN4 = Single zero referenceIN6 = DifferentialIN8 = DifferentialSDADC3 have:IN6 = Single zero...

Hi I wish to use stm32f746 DISCO SAI and WM8994 in I2S mode without DMA as I wish to directly transfer code from a 407 project that works and don't want to involve DMA as there is no need. Thanks Andy. Any

How can I use audio on STM32F7508-DK board ? There is a WM8994 connected to SAI2, but I couldn't find any example of audio using SAI, neither audio example for this board. And the driver for the WM8994 is not provided.

I watched many examples on other boards, but they are always using I2S so I couldn't transposate to my case (SAI).For now, I just would like to connect inputs (Jack IN1 or mems microphone IN2) to the output to understand how it works (maybe first via...

STM429I-EVAL1 Joystick Interrupt by ISR

Hello,I am using a STM429I-EVAL1 board. With this I try to trigger an interrupt by pressing on the joystick, which is on the board. The interrupt is executed correctly a few times, but then it aborts. You can't tell when, it can abort after the 10 ti...

[ NUCLEO-L552ZE-Q ] Why "EXTI Line 14 interrupt " not "EXTI line 13 interrupt"?

I tried this tutorial"https://www.stmcu.com.cn/ecosystem/chip/chipfamily-STM32L5-4", it was not in English. bu the illustration is clear, I tried it in STM32CubeIDE version 1.4.0 on Ubuntu 20.04.1 LTS. When I went to the last step - Setting NVIC_S an...

Keeping PA15 low during the init

Hi community,I'm using STM32F303RE, in that I'm using PA15 as a GPIO which is connected to a Relay, but I recently found out that the PA15 is a JTDI pin which is being pulled up internally, so whenever the STM32 resets, it gets high and after GPIO_in...

Reboot necessary after OTP write?

I am using the STM32L432KCU for a project. I intend to use the OTP area for writing persistent device information (serial number, encryption keys, etc).Is a reboot necessary after writing to the OTP area?Can the OTP region be written to 32 bits at a ...
