I am using the stm32f411 with clocks set to run at 64MHz. I am trying to read two adc channels triggered by timer 3 cc1 also using DMA2 stream 0 for data transfer.Tim3 CC1 is set for toggle on match. The adc is set for external rising edge.I want to ...
Hello,In my project I need to sample single PWM pulse with ADC (Current and Voltage). I'm using STM32L451CCU.I have configured timer 15 to produce PWM signal with channel 1 and used channel 2 as the clock source for triggering timer 2 through ETR1 , ...
I'm going way out on a limb and designing a small uController board based on the STM32H7A3. I've been prototyping the software for a while now on a STM32 Nucleo H7A3 and a STM32 H7B3 Disco board. The Nucleo board uses the 64 Mhz HSI clock but calls...
I have the following : HAL_SPI_Transmit(&hspi2, &txBuf[0], 1, 50); HAL_SPI_Receive(&hspi2, &rxBuf[0], 1, 50);I have the following code .... STM32L476 is a spi 3 wire master. The Transmit appears (logic analyzer) to be working fine, however I am ...
I have a very strange issue with an STM32F405RG/407VG regarding the RTC: it only works, when I am in debugging mode and add the “hrtc�? struct into live expression and the instance handle is open!My code is pretty simple: I have 2 globals:RTC_TimeTyp...
Hi all,in my project I reconfigure SWD pins to work as inputs and therefore I can't debug/upload new firmware using software system reset. And here's my question - how to modify Startup Script (attachment) so that ST-LINK/V2 would upload (or debug) n...
Hello,I would like to know if there is a possibility to readback the MPU confiugration for each configured region? HAL only provides a setter function. If I take a look into the internal implementation, it seems that regions get overwritten, when I ...
Hi, I am trying to detect a 3v PWM frequency with my STM32, I have my live expresions setup for my variables, but the values do not budge from 0. Im sure it is something up with my code. Any help would be appreciated cheers.
Hi!I am using ADC1 to convert two channels continuously. The two channels are VrefINT and Temperature sensor. However, for some sampling rate I find that ADC1->DR contains only temperature data and for other sampling rate, ADC1->DR contains only Vref...
