Parallel signaling using fsmc

Okay so I'm trying to use FSMC in order to control 16 bitlines and a (custom) clocksignal for driving multiple LED drivers. (the final goal see "data-signal")My first goal was to be able to drive the 16 bitlines, this works as expected. (see "without...

if i use uart dma channel handler for receiving the data by using the uart i received whole but every byte of data got double why

void DMA1_Channel6_IRQHandler(void){ /* USER CODE BEGIN DMA1_Channel6_IRQn 0 */ /* USER CODE END DMA1_Channel6_IRQn 0 */ // HAL_DMA_IRQHandler(&hdma_usart2_rx); /* USER CODE BEGIN DMA1_Channel6_IRQn 1 */ /*Checking the proper USART Port*/  //if (hdma...

stm32lL011 20 led lighting.

I have one stm32lL011 20 pin chip. And nothing more than just this chip, it's a bare chip. How can I turn on a led using a touch button? I don't know what to do, can you write me step by step what to do?Thank you all =)

Custom External Quad SPI Loader

Hi everyone,I am trying to create an external loader for my project by ST's "How to create an external QSPI loader MOOC" lesson. Actually lesson's github repository have microcontroller and quad spi flash configurations that I use.  I just change som...

STM32F407 Backup SRAM backup regulator needed ?

Hii would like to use the backup SRAM of the STM32F407 MCU to share boot flags between the bootloader and main firmware.The flag should be used to signal a "boot into bootloader" requested by the main firmware.To boot into the bootloader the main fir...

How to integrate the M24512 EEPROM in stm32f303?

STM32F302R8 - Not giving DAC output.

I am using the STM32F302R8 for motor control application. Need to do pulse-by-pulse current limiting.I have a BLDC drive board that has a comparator that can be used to give shutdown signal to the PWM. For this purpose, I need to give the comparator ...

Can I use Python to program STM32?

I purchased a controller board from HiWonder, who use your STM32 MCU. I asked them if I can use python to program the STM32 but they do not know. Can I use python to program your microcontroller? Do I need to download specific software?

How do I receive an arbitrary number of bytes over a slave SPI peripheral using DMA?

If I want to receive a known number of bytes I can use the library function: HAL_SPI_Receive_DMA()But I would prefer it if when nSS falls to check how many bytes have been transferred and interrogate the DMA buffer.An alternative is to poll, using F...
