I have few doubts as follows:1. Each MEMORY MAPPED ADDRESS is how many bytes wide? 1 or 4 bytes (I think it as 1 byte).2. The ST datasheet for stm446xx says the SRAM is of 128Kb size then,start and end addresss is 0x20000000 to 0x2001FFFF but, bit ba...
I need cheap microcontrollers that have six usart and uart.Do you have your recommends ?
Hi!I'm trying to lock internal flash on STM32L4RZI MCU from writing, to disallow software to write on itself.I use ST-Link utility, and when I lock at least one sector(In option bytes window), The flash is erased and then lock the wanted sector. I t...
On PIN/BALL defintion table of H7 MCU datasheet, these are a lot of alternate function pin names, such as TIM15_BKIN, TIM15_CH1N. Where can I find the detail describtions for these pin names?
As I am trying to write the data into board flash memory, Is ther any example code to write the 64bytes of data into board flash memory.I have tried the below shared code but its not showing the result I want.flashAddress = 0x08040000void Write_Flash...
Hello, trying to get DMA transfer to work.This does work fine: //INIT DMA static void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE(); /* Configure DMA request hdma_memtomem_dma1_stream1 on DMA1_Stream1 *...
hello everyone,how can I solve this problem, I'm stucking here, I can't understand where is the problem, this error is duplicated 4 timesthank you
hi dear.I built a custom board based on the Stm32f796i-discovery Board.I am trying to link TouchGFX but I can not write image to External Flash Memory (MX25L5124G).The MX25L512G_STM32F769I-DISCO.stldr file is located in the External Loader folder of ...
Hi,I'm working with DMA on an STM32F745. I have enabled a DMA interrupt for Transfer Complete on SPI RX, when the data is ready to be read. To do this, I set the TCIE bit in the DMA_SCR register. In the interrupt routine I read the data and I disable...
