Hello, I'm experiencing a problem with PB6 pin on STM32G474 MCU when any type of reset occurs. The pin goes low for the whole duration of the reset pin being low, and stays low to around when the FDCAN is initalized. This is a significant issue, as ...
Hey guys. I'm trying to use the SPI1 interface on the aforementioned nuncleo board, but no luck whatsoever.I want to transmit 2 3Byte commands to a dac device. The first one is 48,0,0 and the second one is 55,255,255. My code is: uint8_t msg_Tec[3]...
Hi,I have question, I wanted to check whether a condition has reached below threshold level. How many check do I need to do whether it has reached the level below. Does it need to be three check or do a 20 check and average out to see if it below tha...
Hello,I am developing an application on STM32H563 MCU and NUCLEO board.I have the following problem when trying to configure USART2 RXFIFO threshold.In particular, on a transmission completed event, inside the ISR, I need to configure the RXFIFO thre...
Hi!I'm using STM32H745 dual core. The reason behind it is as I have to do very fast measurement on one core (M7) and the rest of the slower things on the M4. The M4 is mostly used for communicating with the external world. I have setup SPI3 and SPI4....
I'm looking at https://www.st.com/resource/en/application_note/an4187-using-the-crc-peripheral-on-stm32-microcontrollers-stmicroelectronics.pdf. It says:Two examples are described, with the measurement of execution time:• CRC_usage example: how to co...
I am using ADC regular simultaneous mode with stm32f427It works nice with the pulse signal is comming after dma start(HAL_ADCEx_MultiModeStart_DMA)but if the signal is comming before calling ADC dma start code it going to infinityhow to solve this?i ...
Hello,I am trying to generate a pulse-triggered waveform continuously by using DAC and DMA in STM32H735RGV6. To do this, I have opened DAC OUT1 with the following configuration.After that, I set up the TIM12 with the following configuration and expec...
Greetings,This is a revival of this question but refocused on the actual line of code iteself. Also, I thought that I may have better luck on this board instead.We have a problem where a certain call of memcpy overwrites/corrupts memory elsewhere, bu...
Hello, we are a manufacturer company that uses STM products. We developed a device using stm32f410 and stm32f446 products 2 years ago. We have a few processors from this old series, stm32f410 and stm32f446, and they work without any problems. However...
