Hi, I designed a board with uC STM32H743 that works with a 480x800 display connected through the LTDC peripheral, I don't quite know how to use the LTDC, I don't have ram for the buffer of the entire display. What I can do is fill the background with...
Hi, this is my first post so I will try to provide as much information as possible. Any help is greatly appreciated! I will try to provide any missing details.What I'm Trying To DoI am trying to erase sector 1 using the HAL provided APIsTried HAL_FLA...
Hi,We would like to use the standard USB DFU supplied with a STM32H747IGT6 with our own Vendor ID (VID) and Product ID (PID) instead of the default STM VID and PID. We are entering USB DFU mode by pulling the boot mode pin hi. We can run the DFU thro...
Posted on September 14, 2017 at 06:05Hi,I got the following error when I try to run an example of RTX_Blinky from Tutorial: Cortex-M7 STM32 F7 Discovery Kit.The example software zip file is from www.keil.com/appnotes/docs/apnt_280.asp.C:\Keil_v5\ARM...
Hi,I am developing and exploring a register programming based SPI driver. I took my time to read the datasheet and analyze the SPI startup sequence. For testing, I am using pre-programmed SST25VF080B memory IC. I wrote a simple and low speed (less th...
Hi, My application has a bootloader, recently, I allocated a large block of memory on top of SRAM to protect the data from system resets, this causes the highest address of user stack changes, when this highest addresses of user stack are different i...
Hello all, I developed a UDP server/client with the objective to send and receive data simultaneously. The code has some problems in the way its written (e.g., unnecessary loops, variable definitions inside a loop...), but I'm only interested in solv...
Hello, When programming an ELF file into a new STM32L431 chip(blank FLASH) for the very first time, the program does not start running automatically. It only runs correctly after a full power-off reset.However, after this initial procedure, new ELF f...
Hi All, I need to design an PCB with STM32C011F6 (TSSOP20 package) that will have few inputs, few outputs and an ADC input (0V-3.3V). I have seen the hardware design guide which talks about integrated oscillators of 48MHz and 32Khz but I'm not sure ...
Hello,I'm trying to snprintf into a data buffer, but the application dies precisely on this call. I'm not using nanolib because I want exceptions. My CMake file looks like this: Notice that I added the -u printf_float to the linker flags. Is this not...
