For a couple of days now I have been trying to get some visuals on a ILI9341 LCD screen.I'm working on a STM32F723E-DISCOVERY board. The LDC screen works with an 8080 controller. According to the manual of the device the internal IM bits define wethe...
i want to generate variable duty PWM using TIM1 & DMA but it not work.uint16_t variable_duty[10] = {0,1000,2000,3000,4000,5000,6000,7000,8000,9000}; HAL_TIM_PWM_Start_DMA(&htim1,TIM_CHANNEL_1,(uint32_t*)variable_duty,10); HAL_TIM_PWM_Start_DMA(&hti...
Hi,I want to use a double precision input parameter for an inline assembler function, for exampleint32_t Double2Long(double a) { int32_t c; asm ( " vcvtr.s32.f64 s0,%[in] \n\t" " vmov %[out],s0 \n\t" : [out] "=r"...
HiUsing STM32 Cube MX, I can select a data bus of 32 bits for PSRAM (FMC interface) on STM32F723IEKx MCUs. however I do not see a list of supported transactions for such a bus in the paragraph "12.5.2 Supported memories and transactions" in the RM04...
Hello,Currently, I'm working on a project in which the boat-loader is already present. Now, in the boat-loader, there are several things which I'm not using i.e Systick clock, DMA etc. So, I want to De-init all the unnecessary peripherals to run the ...
For a hour I'm breaking my head. How it this possible? What's going here?unsigned max_prio = 5; __set_BASEPRI(max_prio); __DSB(); __ISB(); uint32_t basep = __get_BASEPRI(); printf("basepri=%u\n", basep); //>>>>>>>>>>>> it prints 0 ! Using the At...
I have an EXTI interrupt with a shared handler, EXTI15_10_IRQHandlerNormally there should be only pin 15 interrupt.So I did this:void EXTI15_10_IRQHandler(void) { if ((EXTI_D1->PR1 & (1<<15)) != 0) { my_handler(); EXTI_D1->PR1 = ...
Hi,Im trying to resurrect this project from 2015 (Software AWD control for RC Cards using 4x brushless motors):https://github.com/hammerfet/BrinirControllerIve built his VS2013 solution and got all that side working fine. However, next is to determin...
hi stm,i am using multiprocessor communication uart mode in STM32F303VC. i am not able to communicate UART2 at 312500 baud rate. i am using external oscillator of 10 MHz . please suggest what should be the clock setting for that.thanks,roushan
Can anyone from ST let me know when and if the STM32H7A3RIT (64-pin part) will be available. This is an important part that can be extremely useful in a large range of applications allowing much smaller form factor for the application than the parts...
