Hi everyone, I'm trying to capture a PWM signal's duty cycle and period using a timer (TIM3 in this case) in PWM input mode. However, when I run the following code, I see no updates in the CCR1 and CCR2 registers, which should have the values of my ...
I am using stmf413xx to talk to M25P16 via SPI. I have working code that can send and receive data to flash via SPI but when I transition to HAL (I want get to interrupts eventually) it no longer works.The code that works iswhile ((SPI3->SR & SPI_FLA...
Hi,I am currently playing with a G071 nucleo board for possible use in a future project. I have trouble achieving datasheet power figures.At 16Mhz (regulator mode 2) using HSI, in run mode I get 1.20 mA with a While 1 loop. This is 0.1 mA above data...
Hello,I am having a bit of a problem with using the ADC on the STM32L072 in combination with the External Trigger and the DMA.I have just two conversions set not continuous mode and not discontinuous, but the DMA is set to take 32 results.If I trigge...
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...
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 = ...
