Hello,I just bought a STLINK-V3 because of its faster USB interface to speed up debugging with STM32CubeIDE. Unfortunately I cannot get it working. With some settings the target is not found with others there are errors during flash programming. Does...

STM32F746/AtollicI want to receive periodically a certain number of bytes from an ADC via SPI using DMA.Since there is no Tx line, I thought it would be correct to set the SPI at SPI_DIRECTION_2LINES_RXONLY and to program a DMA for Rx. I called this ...

With an STM32F764 I want to receive 33 bytes from 11 daisy-chained 24 bit ADCs via SPI in read-only mode. The received data looks okay but there are 37 to 39 bytes in the buffer. Also with other byte numbers I receive 2 to 6 bytes more than expected....

Hi,with my recent download of CubeMX I have got emWin version 5.44. Are there newer versions for the STM32F7 family? I would be interested in version 5.48 or higher because of the changed MENU widget function.RegardsJan

Hello,I have an STM32F746 in an own PCB design. A 128 Mb DRAM IS42S32400F is connected to the FMC pins, similar as on the STM32F746G-DISCO board. I can write and read data but there are errors which occur in a systematic way:I start writing 16 bit da...

Now it works. I have added a dummy Tx DMA for the number of bytes I want to receive:/*DMA 1 / channel 0 / stream 0 transfers data from external ADC to sample registers*/ __HAL_RCC_DMA1_CLK_ENABLE(); /*DMA clock*/ hdma_spi3_rx.Init.Cha...

It works! I had missed that.

Thank you. So is there a bug in SPI_DIRECTION_2LINES_RXONLY?I changed it to SPI_DIRECTION_2LINES and programmed a Tx DMA but so far I couldn't receive any bytes.In HAL_SPI_Receive_DMA I found:HAL_StatusTypeDef HAL_SPI_Receive_DMA(SPI_HandleTypeDef *h...

Just to close this topic, I replaced the IS42S32400F by a MT48LC4M32B2P and everything works fine - without knowing why.

Yes, DISCO works fine with the same project, except that SDCKE0/SDNE0 are moved from PH2/PC2 to PH3/PC3.This is my setup for FMC and SDRAM:/* FMC initialization */ void FMC_Init(void) { FMC_SDRAM_TimingTypeDef SdramTiming; //Perform the SDRAM1 me...

STLINK-V3 support in STM32CubeIDE?

How to avoid unnecessary clocks when receiving data (simplex) from SPI with DMA?

Why do I receive the wrong number of bytes from SPI with HAL_SPI_Receive_DMA?

Latest STemWin version?

Data is written to SDRAM at the correct address and at a wrong address with 32 byte offset simultaneously. What could be the reason for this?
