Given an MCU (say an STM32H755ZIT) and a function (say SPI2_MOSI), how can you find which pins may be configured as SPI2_MOSI, short of clicking on every pin in the Pinout View of the MX Device Configuration Tools?
I'm using the STM32H753ZIT6 NUCLEO Board. For some reason the User LED's are on by default even without any code on it. I tried to press the reset button but it would just blink the led's. I read on another forum to short the BOOT0 and Vdd pins but w...
Hello,I would like to configure PA11 as an EXTI pin. I know that there exists the hardware limitation that there cannot exist two pins with the same pin number in different ports configured as an EXTI pin (I.E., I could not configure both PB11 and PA...
We are on the second generation of prototype here. On the first generation I had an MCU fail for reasons I couldn't trace. This was from a set of six. I have now powered seven of the second generation two have had MCU failures. The second failure w...
Good day Folks,I am hoping you are able to shed some light on this odd XSPI clock behaviour. I have connected XSPI2 to a W25Q64 Flash in QSPI mode.There are 'preamble' clocks present prior to the NCS being asserted. I've noticed that the number of p...
I want to create and application on a STM32H745XI-DISCO. I am not using M7 core only M4.Reference manual says that upto 864kB of SRAM and 2MB of flash are available.I will receive the application sw via Can. My bootloader will save it RAM and after ...
Good afternoon, I have some questions for reading multiple channels of the ADC in continuous mode and map the results in the DMA. I have been able to monitor the voltage coming from a potentiometer and map it into the DMA and i can see the values in...
Hello everyone New STM32 user here, more specifically STM32 U545 RE-Q. I am kind of new and i would like to start acquiring some data with the STM32 ADC, triggered by a timer, and send the data to the DMA so that i can use the CPU for other stuff. D...
As mentioned in the topic subject, I would like to implement I2C Slave device which will simulate the BQ769x2 device. For development I'm using STM32F4 Discovery board, but the final product will be deployed on STM32L0.Master device is first trying t...
Hello,there seems to be a problem in function SD_read with reading data in DMA transfer mode to cached buffers.I've enabled cache handling with#define ENABLE_SD_DMA_CACHE_MAINTENANCE 1but there is a serious problem with calling SCB_InvalidateDCache_b...
