Hi @, I am trying to configure the display with the H7 series, and the connections are accurate, I've tried more than one LCD to check if the problem is in the display but there is not response from the display side. I wonder if the MIPI DSI initiali...
Hi!I have STM32F469 and I am analysing how to connect an USB port to it.My MCU will act as a device. PC will be the host.My MCU has power supply equal to 3.3V which is created via LDO which is independently powered (not from VBUS, from host’s USB).MC...
本批在测试一款STM32F407VET6，在测试中发现设备授权码丢失的问题。1. 授权码的工作机制设备生产通过软件发授权指令给到设备写入授权码，设备收到该指令后读取 FLASH ID ,然后进行加密，把加密后的数据写入 OTP 区(0x1FFF7800) , 编程成功后读出来验证是否写入成功，如果成功则重新启动，否则返回失败。2、问题分析通过单步调试，FLASH ID 是正确的，但是读出来 OTP 的数据有一部分变为全零了，所以数据比对不通过。
i use LCD-TFT display in microcontroller STM32H757.i need to store framebuffer data in extern sram(S61WV102416BLL)i use stm32H757i_evk board. i download example code, all example code use External sdram(IS42S32800J) to store framebuffer.i not use Ext...
Hi,i a trying to figure out, why my fdcan is not sending databytes. It only sends the id.And i think i found a bug. Or maybe its just me having not enough knowledge to comprehend it.In the function "FDCAN_CopyMessageToRAM" there is a part, where the ...
Hello,i am currently working with MATLAB/Simulink and followed this tutorial: https://www.youtube.com/watch?v=535gxJa72v0.When I tried to bring the Pulse Generator to its maximum with Digital Write, surprisingly it already stopped at 25kHz. After som...
I want to use DMA with ADC1. For this I made the following configuration (file attached). I have an error when calling the HAL_DMAEx_List_InsertNode() function. The error code is HAL_DMA_QUEUE_ERROR_OUTOFRANGE. I don't see where the problem comes fro...
Hi , I am using STM32L072 of 192Kb series controller. For our project we need FOTA and we are stuck at CRC calculation. As of my knowledge ST needs FFMPEG format for CRC. How to read FFMPEG format of a binary file ? Currently we are using JFLASH tool...
Hello,I am developing a project using STM32H742VIT6.I have tentatively tried to configure SPI on PA4-7 outputs and USART1 TX on PA9 simultaneously. However, when I try to implement this configuration on STM32CubeMX, it automatically places USART1 TX...
I am seeing this issue on around 20% of new MCU's.I am programming brand new STM32G474's through the internal bootloader over SPI. When put into bootloader mode, 20% of the MCU's wont respond with the synchronisation byte. I have played around with t...
