I'm trying to implement a 10 us delay using TIM2. This delay is inside an EXTI interrupt handler.I am not getting a return at the end of 10 us.In the clock configurator, I used the max PLL clock possible, 64 MHz. Is this OK? I don't know what else to...
Hi I am working on a small project where I need to sample couple of ADC channels.I am using STM32F405RG. ADC1 is running in continuous and scan mode with DMA. I am using ping pong buffers to send ADC data through USART. After gathering some data I pl...
Hello,I am trying to use the memcpy function to transfer data from the ADC data buffer to a separate data buffer, but when I call memcpy, only the first 1400 of 6000 samples gets copied, while the remainder of the buffer does not get updated. I notic...
Hello!Dealing as newbie with STM32 MCUs, I'm focusing on projects of STM32Cube_FW_H7_V1.8.0 packet.As my goal is to develop on STM32H735G-DK, I'd need an application or an example which uses STemWin library. Unfortunately I can't find such a combina...
Hi all,I'm trying to program my Nucleo L432KC in pure asm, but even after following the data sheets and using the correct memory addresses I can't get any of the pins to turn on (nor get the onboard LED to ignite). Is there something key I'm missing ...
HSI or HSE ?carefully read the pictures
I'm using STM32F103(blue pill). Usart1 connection with pl2303. My codes right hereuint8_t data; /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { HAL_Delay(1000); if(HAL_USART_Receive(&husart1, &data, s...
STM32F303VCT6 don't have MCO-PLL divider ?but gpio have 50 MHz band.; how i output 72 MHz ?
DearI have configured ADC3 using MXcube:In my main I tried this: LL_ADC_ClearFlag_ADRDY(ADC3); LL_ADC_Enable(ADC3); /* USER CODE END 2 */ /* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { LL_ADC_ClearFlag_EOC(ADC3); LL_ADC_ClearFlag_E...
The first non-comment line in every LL source file is:#if defined(USE_FULL_LL_DRIVER)This is above any #include lines, which means that if you want to use LL drivers, you must define USE_FULL_LL_DRIVER in your project settings.To avoid a proliferatio...
