STM32 MCUs Products

Not able to Restart MCUs after enabling WWDG timer.

Hi, I am using STM32F413ZH Discovery Board and trying to reset MCU from the WatchDog timer. So I found there are two WatchDog timer in FreeRTOS IWDG and WWDG. and one example I created with toggling the LED in that I enabled the WWDG timer. after tog...

STM32F303 CubeMX injected conversion of ADC rank 2 do not work

Hi,I'm using the STM32F303 and CubeMX with low layer.I try to read two ADC-values with the injected conversion. In CubeMX i defined two ranks to read the values from the ADC. For rank 1 everything works fine and in the JSQ1 register contains the righ...

We can use the usb CDC (Virtual Com Port) and 2*USART together? i need when connect the MCU to PC show 3 ttyACM (CDC,UART1 and Uart2), i use MCU STM32F042x4.

Note: when i use the CubeMX and configure the pins for USB cdc and the UART1/2 show warning conflict

Interfacing STM32F412 and using DFSDM with 32Msample/S 1-bit Delta Sigma ADC

Hello,We need to use analog front-end providing a 1-bit Delta-Sigma interface (clock output + I channel and Q channel) with STM32F411 or STM32F412, initially we planned to use the STM32F411 but i noticed that the STM32F412 has a DFSDM peripheral wh...

STM32l071 USART1, FE interrupt generated, but I didn't clear it's status flag, Will it be interrupted all the time?

STM32F103 Npulses example

Hello. In order to drive a stepper motor with CanBus, I want driver a L6208. I would use a timer to generate Npulses. I've read AN4776 (General-purpose timer cookbook ) but I don't understand somethink, I can't run the timer.Any people have example c...

I am using SX1261-2 radio with stm32l433. The radio provides multiple interrupts such as RX_done, TX_done etc. How do I make sure (need help with syntax) that my MCU wakes up only if there is only a RX_done interrupt and not other interrupts.
