STM32 MCUs Products

I keep getting Ethernet transmit underflow on stm32f7xx series processor.

Additionally, the receive marks the buffer ownership to the DMA in a for loop. This also creates a timing problem between the hardware DMA and the receiving task freeing buffers.is there a better code for ethernetif.c?if ((heth.Instance->DMASR & ETH_...

Intentional receive complete UART DMA interrupt after specified timeout

I have configured a UART to receive in DMA mode where the size of the buffer is around 64 bytes. So, basically the HAL_UART_RxCpltCallback() DMA receive complete interrupt will only fire when 64 chars are received. Is there a way in STM32 through wh...

Is it possible and how to use other GPIOs than ADC_INxx as analog inputs ?

The Reference Manual of the STM32L1 talks about "Up to 40 external I/OS can be used far data acquisition purpose in conjonction with the ADC interface".The ADC_INxx pins number is smaller...I saw that we can root pins with the "Routing Interface" per...

STM32 with Atollic (C++ project)

My task is to change our current microcontroller solution to STM32, for this i choose to use Atollic True Studio. My goal is to keep the current software and only replace the hardware access (which is the only mcu specific part). Since all the librar...
