STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
How fast is DMA on STM32H7 mcus? I didnt find any description on how many ticks takes one transaction. I linked DMA to a timer, transfer from memory to port. With system clock 480 MHz and timer DMA request frequency 40 MHz it doesnt seem to work fast...
I'm trying to use the idle line interrupt in combination with dma to send and receive data from the serial port to my STM32F417VG based board.I got as far as being able to send with dma successfuly and also reveive data via the idle line interrupt. T...
Hi everyone. It's my first time posting here. I'm learning how to program STM32, especifically an STM32F303RE Nucleo Board using HAL libraries. These are my resources to learn: Mastering STM32 from Carmine NovielloSTM32F303RE User Manual and Datashee...
there is maybe a mistake at the page 99 in the RM0090 Reference manual document: the bit area 12 is valid or not?
this may be little weird asking to the big guys. But I'm learning how to produce hard fault so as to debug it again using registers. Also I tried initializing np with NULL. but still no success/* USER CODE BEGIN Header */ /** **********************...
I'm using a STM32H747 DISCO boad and I just want to use the M4 CPU. When start, the M7 configs the Clock and does nothing since then. There is only a simple case running on the M4 CPU. The case takes 200ms on M4 while it took only 20ms on a Risc-v@30...
I am working on STM32u585. The STM receives data on SPI bus, cipher data and store cipher data on microSD.Then the microSD is read on PC and data has to be deciphered for human reading.What is the best mean to perform this ciphering process ? Can the...
I am trying to send commands to a Netion display which needs ASCII and then termination of 3 hex 0xFFs.I tried this: HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET); char Cdata[11] = "bt6.val=[1]"; HAL_UART_Transmit(&huart1, Cdata...
I set up the VREFBUF (using CubeMx) to use the internal voltage reference, with a SCALE of 2.048V. When i probe the Vref pin i see a voltage of around 2.2-2.3V, it changes slightly after ever power reset. It is a custom board with a G061c8 micro. The...
