Hi,I am testing the ECC on DTCM on the STM32H7A3ZI. At start of day I initialize all of DTCM apart from a single test location. I have a test which reads from that uninitialized location and successfully provokes the SRAM ECC interrupt, correctly r...
Does anyone know if the PGA OpAmp in the STM32 has the ability to interface with a differential input - like a Strain Gauge Wheatstone bridge? I'm not convinced its going to work because my signal is going to swing +/-50mV, and the OpAmp does no loo...
We are using STM32H743 Controller in one of our LRU (Line replaceable unit).Since February end, The LRU System Test equipment cannot load the programming (.bin ) file to many units. This is the first time this specific failure mode has appeared. This...
Hi,I have an issue on MIPI Display with our custom board, information as below, Core: STM32U599NJH6Frame Buffer Address: 0x200D0000 (Internal SRAM)MIPI Driver : ST7797Resolution: 400*400Reference example : STM32Cube_FW_U5_V1.6.0\ STM32U5x9J-DK\ DSI_V...
Greetings,During the power-on and power-off processes of the STM32F407 chip, the GPIO used as the DAC output will be pulled high for 8ms. The goal is that the GPIO should remain low when there is no DAC output. Adding an external pull-down resistor h...
Hi, We are working on railway projects where we are looking for SIL 2 microcontroller. As per our analysis we found out that we need to integrate the X-CUBE-STL package to make it to SIL 2compliance. And we have found out that it should have supporte...
Hello,I updated my development kit with the example IOT_HTTP_WebServer from the example selector in STM32 IDE. Then I needed to upgrade the firmware on wifi module, which seemed to work. I think I can connect to wifi, but I cannot open a webpage when...
Hi, good morning to all. I'm in the process to design an application based on STM32U5G9ZJT6Q. My first question, please, is: is it possible to have this STM32 drive three different displays, and possibly have TouchGFX manage the whole three ?In my ca...
I've been struggling with a variety of issues with FreeRTOS/LWIP/DHCP/MDNS, before I've even got to implement my application code (which will be a UDP app). I've read all of the documents that have been linked in the forums, I've gone through the off...
I'm writing a small HAL of my own for the STM32F1 and I noticed that sometimes the DMA would read in the wrong order for seemingly no reason. After several tests, I came up with this code: const std = @import("std"); const microzig = @import("microzi...
