Hi, have any of you communicated with a display based on the ST7735S controller? Based on this library: https://github.com/afiskon/stm32-st7735 I converted it from SPI communication to 8080 parallel control, but display does not work properly, while...
Hi,where do you set programmatically (perhaps through a preprocessor directive) the option to lock the micro to prevent read/download of the flashed code but while obviously still allow for firmware updates?Also I could not seem to find any such opti...
Hello, i am trying to use system bootloader in STM32F411 for software update via USB. I use a freertos in my project.Workflow is here: By sending a "BOOT" via Virtual Com Port USB, MCU executes folowing code: SpoilerUSBD_Stop(&hUsbDeviceFS);uint32_t ...
Hello,I am using the STM32H743ZI2 controller with Cortex-M7 and firmware version 1.11.2 for a project where I am capturing camera data through DCMI and sending it over Ethernet using UDP to software that receives the data and builds a video stream.Ho...
I am currently trying to program this external memory using the external loader sub-project created when a project is created for the ST32H7R7. I have been able to successfully write the drivers for the external flash and I have also been able to por...
Hellowe're using MB1550 eval board with mb1379 daughter board and HDF5640-AF-V2.0 (OV5640 on a FPC) to test camera function. We'd like to tests another sensor, i'll design another FPC with our supplier but i need HDF5640-AF-V2.0 drawings to have the ...
I generated code using CubeMX that should permit me to transmit over SPI1 using DMA for RX and TX, as well as CPOL = 1 and CPHA = 1. I very slightly modified the auto generated CubeMX code but see nothing in the SPI CR1 or CR2 registers, nor the DMA2...
I'm using STM32H757I-EVAL and trying to implement SDMMC.However, I get some errors in these parts of code.At first, the error happened SDMMC_cmdAppCommnad.But now I can see the error SDMMC_CmdGoIdleStateI did change frequnecy of sdmmc, enable hardwa...
I am completely baffled by an issue I’m having with the STM32H7 using the SDMMC and a micro SD card. I have the F7 working and two H7 platforms that both have the same data timeout problem.The STM32F767ZI Nucleo board working OK with the SDMMC and a ...
Hi, I would like to test out the UART bootloader functionality for the demo board STM32F469I-DISCO. I am using reference documents AN2606 and Demo board schematic. I am assuming I need to follow below steps to achieve this.Please let me know if I am...
