can I send UART-bootloader commands through non-remapped pins for STM32?
I am using ESP8266 to flash STM32F107 and TX/RX of esp is connected to PA3/PA2 but On chip bootloader receives commands from PD5/PD6 so can i use PA3/PA2 to flash STM ?

My own bootloader for STM32H750, is this possible?
Hi,We have devellopped our own bootloader for the different families of STM32. This is based in one sector of the flash while it is able to reprogram the other sectors. Now I am working with a STM32H750 but this one has only 1 sector... I might alrea...
HAL_SPI_Transmit on F0, F1, F4, F7
Hi!I have module for transmit dates to SPI Interface.Data is - pointer to data buffer uint8_t.In F1 & F4 all will be ok.But in F0 & F7 modules will send *((uint16_t *)pData) (see modules below)Program for F1 or F4 will not work on F0 & F7.Where error...
STM32HAL I2C Slave Interrupt Not Acknowledging After First Set of Data
I am trying to communicate with a Nucleo_L476RG development board through I2C from an Arduino Uno. However I am having difficulty communicating more than one data frame. The first frame will accept the address and the data, afterwards it will not ack...
No LL CAN code in F7 Cube ?
I downloaded the latest F7 Cube package, V1.15.00, to get the LL CAN driver code for the F74x But there is none.And the F74x is not that new, I think this is not supposed to change. Is it so ?Guess I need to switch to the SAME70 XPLD board.

What is the right way to read several ADC channels in autonomous way?
I have a STM32L011-Nucleo board, and I'd like to make a simple code to read two ADC channels independent to the main code (interrupt or DMA mode).HAL library is a bit confusing for me so I'd be glas to see the right set of functions to use.So first I...
