RM0433, Rev 4: STM32H743/753/750 reference manual missing DMAMUX SIG_ID table

Section 16.4.5 talks about the DMAMAX​ request generator but I cannot find a definition for what the SIG_ID bits mean.DMAMUX1_RGxCR and DMAMUX2_RGxCR reference SIG_ID but I couldn't find a definition of these bits.

RM0433, Rev 4: STM32H743/753/750 reference manual missing MDMA TSel table

Section 13.5.12 talks about TSEL[5:0] but I couldn't find the mapping for the Trigger Selection bits.

Did someone use DP83848 in RMII mode on custom board?

I would like use the DP83848 in RMII mode due to the number of available pins in the project.LwIP supports DP83848 with MII only and for RMII just the LAN8742A.The folllowing pins of DP83848 are not connected:RX_CLK, TX_CLK, RX_DV, COL, RXD_2, RXD_3,...

The µC STM32F051Kx has only one SPI and of course only one CS (chip select). It is possiblie to use another and configure it as CS?

Is possible to programm the STM32f051 through RS485 or UART?

I am designing right now using STM32051. Using the only SPI interface for my project, I am struggling how to use the NSS for two slave, that the chip give me only one NSS.It is possible to load my Programm to the chip using the RS485? How could I rea...

[How to] Touch Sensor front panel: how to choose the right cover glass.

Designing a touch sensor is not an easy task. The touch sensor front panel you choose is more important than you think.In touch sensor design there is a high level of complexity and many design choices to consider. Complex physical phenomena and cost...

LTDC does not work with RAM

Hello.When I loaded the array into Flash (used const) It was displayed on the screenBut as soon as I use RAM to store the image it stops displaying, I see a black squareI also can not fill the color programmatically LTDC just does not react

UART DMA TX FIFO sends only single buffer worth of data

Hi,I'm trying to send data via UART6 TX DMA on STM32F429-Discovery board. All is well, if I send packets of size less than 16 bytes (FIFO buffer size). However, if packet size is larger than 16 bytes, only first 16 are sent and the rest of the data i...
