stm32 - Can the STM32H743's FMC drive a 16-bit 8080 bus faster …
2020年2月25日 · I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller. I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC. The transfer frequency does not depend on whether DMA, MDMA or CPU-loop is used. This make me think that the DMA/MDMA/CPU-loop is not the limiting factor.

Can the STM32H743's FMC drive a 16-bit 8080 bus faster than 1.6MHz when clocked at 480MHz? I'm using the FMC of the STM32H743 to drive a 16-bit 8080-bus LCD controller. I've tried using DMA, MDMA and a CPU-loop to transfer data to the 8080-bus, via the FMC.
Can't transmit with SPI (stm32h743). Configuration issue
2018年8月7日 · I am trying to code the stm32h743 for spi communication and i can't seem to transmit. I am using PA5 as SCK and PD7 as MOSI. I read the procedure required that is in the reference manual (49.4.9 reference manual) and wrote the code below but it doesn't transmit 0x3 (checked with oscilloscope).
STM32H7 SPI communication: FIFO management problem
SPI Slave is a Nucleo STM32H743 in simplex mode, clocks at maximum (sysclk 400MHz, hclck 200Mhz, APB clock 100MHz) SPI master is another identical Nucleo in simplex mode, clocks divided by 2: sysclk 200MHz, etc... and spi_ker_clk = 100MHz; SPI master with a prescaler of 16 ie. clock SPI around 6MHz. CRC enabled. Data frame 8 bits. FIFO ...
IEEE 1588 PTP Clock Source in STM32H743 - Stack Overflow
I'm trying to get PTP timestamp on STM32H743 Nucleo board. There is no proble with LwIP and ethernet driver so far except for PTP. I followed the instruction( 58.9.7 Programming guidelines for IEEE 1588 timestamping) on reference manual (RM0433) as follow.
How can I debug a HardFault on my STM32H743 when the …
2023年3月13日 · I am currently trying to track down the reason for a HardFault that sometimes occurs on my STM32H743. I was able to narrow down the culprit to a section of code of about ~200 lines. Now of course I would like to nail it down to the exact location. Some information that may or may not be relevant: I am programming the chip using C, using the ST HAL.
