At system reset, static memory is zeroed. I want static memory to be entirely left alone by the system. I want the memory to have what I put in it, not clobbered. Granted, I have to retain power to the device, but static memory should be able to r...
I am working on a project where the requirement for the microcontroller is to communicate over the CAN bus. The STM32G0B1KET6 is having FDCAN controller inside. It mentions in the datasheet that "The CAN modules are compliant with ISO 11898-1 (CAN pr...
I am using STM32H747i-DISCO board to create multicore MDK-ARM project using STM32cubemx and Cubemx will create the project with both cores under same project file, but when i build that project it will show multiple main file error. How to create a p...
Hi,I need help about LUT configuration of a custom display. I am using STM32L4R9-Disco board. The LUT for the display is given in .xlsx format. However, I am using another display of size 454x454 with that board. Is there any way to generate LUT for ...
Many ST documents says that FT pins are 5V tolerant only in (Digital) Input mode. They are not 5V tolerant when configured in Analog mode and analog peripheral like ADC or OPAMP is connected to it. But are they 5V (or more precisely Vdda + 3.6V toler...
Hi, I am working on a project for STM32F746ZGT6 that uses the RTC clocked from the LSE.In some cases I am seeing an issue where the LSE appears to start (LSERDY reads as 1 within the call to HAL_RCC_OscConfig from the peripheral libraries) but it app...
Hi,I picked up a X-NUCLEO-BNRG2A1, and I am trying to communicate with it through a Nucleo-U575 Board. I basically generated a project template through CubeMX for the STM32U575 and included the BlueNRG-2 (X-CUBE-BLE2) Pack to include Bluetooth HCL/AC...
I have an STM32F429ZI Nucleo board (for SPI master and UART to check everything's working alright) and an EVB-LAN9252-SPI board(for SPI slave).I have to check if the SPI is correctly working, but it seems that I can't debug or check on the slave's si...
The configuration and operation settings are as followsH/W : STM32F429<====TW9912<====AV CAMERATW9912 is renesas video decoderThe pixel clock was confirmed to be 54mhz. Verified vsync/hsync operation.There was no problem with the tw9912 settings.Ques...
Hi there,I remember the stack starts from the top, which means the earlier local variable will be located at a higher address space. I have the following code in the main() function in ARM-MDK IDE: uint8_t v1; uint8_t v2; uint8_t v3; LOG_DBG("&v1[%p...
