The MCU is STM32F401CB.VDD is 3.3V.A few buttons are connected to PA0 (configured as EXTI rising/falling interrupt).When a button is pressed, the IRQ always comes.When a button is released, the IRQ comes rarely, if at all.There's a filtering cap and ...
Hello everybodyI am a student trying out some things with the evaluation board STM32F769I-EVAL.First, I think it is important to say that I have nearly no experience with STM controllers.So, let's look at my problem. The main aspects I am looking at,...
Hello, I work on STM32F407.I want to start the PWM 1 on the rising edge of the main PWM and start the PWM 2 on the failling edge of the main PWM. But I don't know how I can detect the rising/failling edge...Can you help me please ? Thanks a lot.
Posted on June 13, 2018 at 21:06 Hi, I am using Nucleo-144 connecting CAN RX/TX PD0/PD1 to external CAN transceiver, PEAK. The function is pretty straight forward. Prepare data then call HAL_CAN_AddTxMessage() to transmit. CAN_TxHeaderTypeDe...
Hello everyone,I have a development board with the MCU specified in the title. I have used Keil to create a project and flash my board. According to what I understood from the documentation I read and by looking at the startup code:MCU is by default ...
Hi All,I am working with the STM32F302R8. I want to set the system clock as the PLL through derived from the HSI. I want a clock of 64MHz which I should have set through the appropriate registers.I think I have set all I need however, after the RCC c...
Developing code / debugging 2 days ago and all was well.This morning I attempted to flash the mcu (using ST-Link / V2) and it reported back that the Processor failed to halt.Switched to my J-Link and it reported that the MCU was in an Active Read Pro...
I am working with G071 neucleo board. I am trying to debug a program that writes and reads for EEPROM emulation. However, it does not work as expected in dubug mode. The example program provided by ST for Flash runs well in run mode ( Without debugge...
Hello,I hope someone can help with this riddle.We just started working with our custom board, based on stm32h743 (untill now we worked with eval stm32h743-eval board).The internal memories, GPIOs and other interfaces works OK, but we have the followi...
I am working on erasing sectors sequentially in my MCU, from Sector 2 through Sector 7 (the size of flash where my firmware will live). I have found that sequential sector erases will occasionally fail, and any attempt to erase a sector of size 256k...
