I have 2 different mini thermal printers with RS-232 TTL interfaces. Different manufacturers, but I suspect the interface is identical or very similar. Both manufacturers state TTL interface.On the other side I have STM32 MCU with 1 free SPI.My limit...
Hello,The COMParator have option of connection him output to TIMer IC.But timer IC is after edge detection unit.How can I connect the output of COMPx to TIMx in input capture mod (internaly)?
Hi, I’m new to STM32.With STM32F730R8T6 MCU;I want to see the data using CAN protocol and UART protocol while sending data using UART protocol.At the same time, I want to see the data using CAN protocol and UART protocol while sending data using I2C ...
I faced strange behavior on STM32L431CC. I was trying to sequentially add data to archive and at some point the CPU failed to program 8 bytes at address 0x8032018 (8 byte aligned) and at address 0x8034100. I read data from the memory and it is clear ...
There is some way to read directly the byte that are send via SPI and not the int8 that is generate by the function?int8_t buffer[BUFFER_SIZE] HAL_SPI_RECEIVE_DMA(...,(uint8_t*)buffer,...,...)
Can the STM32L4S9AII6 MCU SPI1 be configured as slave and accept a 8-60MHz clock from master? Section 52.2 (page 1852) of the STM32L4S9AII6 reference manual says "Slave mode frequency up to fPCLK/2.", but with the system clock configured in MxCube as...
Dear community membersWe are using Quad SPI in stm32l476 while having a memory to read data but we are facing an issue. Garbage values when entering memory mapped mode.why is that?Thank you.
So I am setting up the DMA for USART1 tx on a STM32F4 on each transfer, and busy wait for it to be done (no interrupt) by polling TC. DMA2_Stream7->NDTR = len; DMA2_Stream7->PAR = (uint32_t)&(USART1->DR); DMA2_Stream7->M0AR = (uint32_t)str...
