reading arrow key from UART
Hello, has anyone ever used UART to read arrow key? I tried using STM32 MCU on CubeIDE, but can only get two characters ASCII number 27 and 91 and couldn't get the third character which is supposed to be 'A' for Up key, 'B' for Down key, 'C' for righ...
STM32H753XI. When 2 DMAs are working and writing data from SPI1/2 to SRAM1/2 the received data has errors. When only one DMA is working the received data has no errors. Why?
I am using STM32h753XI.The MCU uses 2 SPI channels (SPI1 and SPI2) in slave receive mode.The MCU uses 2 DMAs channels (DMA1 stream0 and DMA2 stream0) to read the data from SPI1 and SPI2 and write it to SRAM1 and SRAM2 respectively.The input SPI sclk ...
BOR vs PVD Detection Logic
We have seen PVD triggers when there is transient load of 1A added on the 3.3Vdc (loaded additional to our design through electronic load) and it triggers when the transient load dips the 3.3V for duration of ~450 micro seconds.We have seen BOR trigg...
Resolved! STM32F051 ADC Vref problem
Hi there!I need your help before i became crazy. I configurate (with DMA) 9 ADC input plus one for Vrefint channel of my STM32F051 discovery, Now my problem:i read a wrong value of Vrefint channel the value is equal a Ing1. But if i configure ony Vr...
Resolved! STM32L432 use both usart1 and usart2 receive missing data
Hi,I write the firmware using STM32L432 (NucleoL432-KC) used usart1 and usart2 with DMA RX/TX and received idle line.The usart1 and usart2 using pin of the same port (PORT-A)The problem is lost receive data if I receive data on both port at the same ...
