Hi everyone,I recently revamped a product with a STM32F427 with a new STM32H745. Both cards have an external RAM of 16Mbyte. In the STM32F4 the data bus is 16bit width while in the SRM32H7 the data but is 32bit width. Both cards are set to go to the ...
In the ancient times, RM0316 used to contain also 'F302, but that changed long ago. Yet some relics remained, causing confusion: and a couple of more, related to these two, easily found by textual search.JW
I have configured Octospi for Single SPI mode in CubeMX and am attempting to use HAL_OSPI_Transmit() to write 48 bits to my device (as I would using a basic SPI peripheral). But the code fails. The OSPI is in the HAL_OSPI_STATE_READY mode, but needs ...
Hi allI'm using a Nucleo U575 board for reading a GNSS module. I configured the USART2 port with DMA (in circular mode, port 0 as it's peripheral to memory), Request is USART2_RX, Interrupts for USART2 and GPDMA1 are enabled and it works just fine. I...
Hello all,I am trying to read temperature with the G030. At the moment there is quite a large difference between actual temperature and temperature read by the MCU (true temperature around 23.5 degC while MCU reads 32 degC)ADC_Init code:static void A...
For testing purpose i am transmitting an array of 8 bytes with . But still the FIFO transmit ERROR flag in HISR is always getting set. Please do help!
Hi,The stm32u5's internal flash has feature "10 kcycles endurance on all Flash memory. 100 kcycles on 256 Kbytes per bank".Please advise the memory address of "100 kcycles on 256 Kbytes per bank".Thanks,QiZhang
I create a simple blocking delay timer using simple looping and run in STM32H7a3ii. The program was linear, no code optimization, no interrupt. Without any changes of the blocking delay timer function, i found that when the blocking delay timer place...
