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...
If my data is more than one 32-bit word and I have to write it one 32-bit word at a time to the FIFO, is it possible that the USB controller could send just the first 32-bit word? Is there a way to stop that from happening?Thanks```USBx_DFIFO(1) = se...
We are developing a device using the STM32H743.We are setting up the GPIO during initialization, but I am wondering about something.What is the GPIO output before initialization? Is it high impedance?Or does it change depending on the circuit connect...

I have to interface the nucleo-u083rc with ads1293 to get ecg data. I have provided the code from stm32cubeide and also the ioc picture. I have connected the D4 pin(MCU) as DRDYB pin and SPI1 and I use channel 1 from the sensor. Please help me with t...
SpoilerHi Friends, I have a problem using the DAC with the DMA. I have configured the DAC's DMA in normal mode and I want it to generate an interrupt at the end of data transmission to let me know that it has sent all the data to the output. The dat...
FYI,you can build, load, start and debug also the "Appli" project (not just as FSBL).The linker script (selected as default) "STM32N657XOHXQ_LRUN.ld" loads and executes in the same way.In order to avoid this warning about "LOAD segment with RWX permi...
Dear sir, dear missis,I'm working with an STM32L053r8 on a step by step know-how. My interface with the bootloader runs fine, and I am able to cover the main features provided through this interface. The issues I try to cover now is the right underst...
Hi,in the MCU selector app, in the Example selector, there is a long list of examples, all using acronyms (see screenshot below). Some are obvious like "ETH" but most are not.Some questions:1) Where can I find a table/list that explains what each of ...
I am using stm32h745zit3, with the flash is IS34_35ML04G081. I have initialize the below parameter but after writing in to the flash and reading the data but some bytes are corrupted. Please help to resolve this issue. uint8_t buffer[2048] = {0}; i...
