I am using STM32F103RCTx and STM32CubeIDE for developing a small application.I am tuning a vacuum pump DC motor using PWM signal with TIM1 CHANNEL_1. But I hit a small problem when I start debug the board. The motor is running from the time the IDE s...

With STM32CubeIDE and freeRTOS for STM32F429 chips, the IDE generate code using freeRTOS V10.3.1. I could setup heap5 with SDRAM enabled and won't be affected by later regenerating code when changing .ioc file. The cmsis_os2.c file works fine. Both t...

I have been using STM32CubeIDE for quite some time. It's a great tool. How ever, I have been experiencing a bug in project settings since I updated to 1.6.1.Usually, I put my code in a separate folder, thus I could build up a project using existing c...

Thanks for reply. I do use the HAL functions to control PWM signal. The board runs normally by itself. What bothers me is that when I am debugging the board.

Thanks for sharing the info of MCU's reset states.The motor runs when I am holding reset button. The PWM pin output 2.33V when RESET pin is low. Maybe I need to add some extra circuit to make it work.

Don't know the tool chains you are using. Just show how I did in STM32CubeIDE using STM32F429.In you flash.ld file, define a memory area that store your cached data./* Memories definition */ MEMORY { CCMRAM (xrw) : ORIGIN = 0x10000000, ...

As far as I know, CCM has only one limitation: DOES NOT support DMA. If you are to use “O3" compiling option, be careful with the optimized code's behavior. In "O3" mode, some variables may be accessed directly from register rather than the memory. I...

Try to initialize this GPIOC, GPIO_PIN_13 to HIGH and LOW state individually. If this pin is initialized HIGH and LED off, with LOW and LED on, the check your code. If PC13 initialized HIGH and LED is on, the your Bluepill's user LED is not working i...
