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...
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...
Good afternoon.I have configured SPI2 on STM32L476RG as Master Half Duplex, clock = 4MHz, CPOL = 1, CPHA = Edge 2. I am connected to a Pololu 2736 demo board (LSM6DS33). The timing diagram for the part shows resting clock as high (CPOL = 1) and MIS...
I want to read and write application code with comments in STM32 MCU flash or external memory.When I read flash from STM32 MCU I want comments also present there in code.How can I do this? It is possible with MCUs inbuilt memory or need external m...
Well, I know that this is the most commonly asked question these days, but let me please ask it. Maybe it will help me and future readers of this post.I was working with STM32 MCUs for a quite long time, works great and it is planned to use new versi...
