Stange performance comparison between STM32F427 and STM32H745
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 ...
Resolved! RM0316 (i.e. 'F303) - 'F302 relics
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
How to configure Octospi for Single SPI mode using MX and HAL
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 ...
HAL_UART_DMA_Pause() does not pause the UART receiving bytes
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...
Resolved! G030 temperature sensor results (very) inaccurate
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...
Resolved! Hello, I am working on UART Transmit using DMA for STM32F401RE board.I have written code for register level operations.I am using DMA1 with MSIZE of byte and MBURST of 16 beats, total data of 48 bytes. Getting FIFO transmit Error. What is the issue?
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!
