Hi, I am writing a driver for the AD5262 digital potentiometer, which uses SPI type serial but requires a 9 bit data format. I would much rather use the HAL SPI library (which has worked on similar AD family pots) and not use bitbanging. However the ...
Hey,I use STM32H745ZI, I want to create an area for shared memory between the cores, I chose AXI SRAM because I need access as fast as possible for the M7 core.The shared memory is intended solely for shared information between the cores.I have two q...
On STM32F401 or any STM32,how can I read back the status of IWDG, ensuring that's it's running, as a safety measure?As I know direct counter value is not accessible, that would be ideal to see that it's not stuck. How to detect if LSI (thus IWDG) sto...
Hi all,I'm new on STM32H747XI-Disc0. I ve started learn step-by-step everything from basics. So, I'm sorry for my basic questions...According to my tutorial timeline, today I ve started to learn UART communication. I tried to type a small example :- ...
Hi ST Community,I'm using the B-L475E-IOT01A card and I have a problem. As soon as I run my code in Debug mode, I get the HardFault Handler (SIGTRAP) error. I want to use the HTS221 temperature sensor and I'm using the BSP for this sensor (hts211.h)....
I'm looking for an OTA feature using IAP method on STM32H563 using USART communication. I wanted to know, if there is any IAP library available in C for the same along with the documentation, which I can make use of.Regards,
Hi everyone,I am using an STM32h7 to program an STM32L151 using the system bootloader through usart.When I ask for the supported commands, I get that the erase command is between them but, surprisingly, when I try to use it I get a nack.Then I read t...
is it possible to configure external voltage reference in stm32l496vgtx? this feature is there belongs to this board.
Hello forum members,I am working on a project where I need to establish communication between a GUI and an STM32H745 microcontroller over USB. Specifically, I want to send a memory mapping address along with corresponding data from the GUI to the STM...
