Hello,Using HAL_UART_Receive_DMA() function and expecting an N length message, so have set the buffer length and transfer size to N.The communicating equipment sometimes adds an extra character / or drops a character which is taking my DMA out of syn...

Hello,Are there any resources similar to AN3364, that describe the migration directly from F4 to F0?Thanks.

Hello,Has anyone seen ADC noise generated by the 50 MHz RMII clock (PA1) affecting the measurement on ADC1_IN0 (PA0)? (approximately 100 codes in 4096).If so does anyone had a fix to suppress it?All other ADC channels used do not have the same level ...

Hello,I've been trying to write my own HAL to replace the STM32 HAL and recently I have been trying to write an LwIP interface, with guidance from this forum and the examples provided by ST and other users.My Individual files compile fine, including ...

Hello,Just wondering if anyone knows the reason for the duplicate writes to the following registers in the HAL Ethernet code please?ETH->MACCRETH->MACFCRETH->DMAOMRETH->DMABMRIn the example shown below (from HAL code) the DMA0MR register is written t...

Thanks Omar for replying. A couple of questions please?After I do HAL_DMA _Abort() how do I restart the DMA and UART interrupts?Is this done in HAL_UART_Receive_DMA()? Or do I need to reinit the UART and DMA again?Is the DMA pointer reset to the star...

Hi Karl, thanks again for taking the time to reply. With respect though (and not wanting to be inflammatory) changing to half / full complete and circular IMO does not actually solve the problem, it just means the problem would manifest in a similar ...

Hi Karl,As I said in my original post, I have used HAL_UARTEx_RecevieToIdle_DMA which isn't satisfactory as the communicating equipment inserts idle conditions periodically inbetween bytes - makes the problem worse.I am currently using HAL_UART_Recei...

Are you using the same buffer location for transmit and receive? Or are you somehow copying the data to another buffer before transmitting?

@waclawek.jan Thanks for your helpful answer.I would only disagree with the following statement (if it was in regards to my question, that is)"F0 and 'F4 are at the very opposite ends of the spectrum, it does not make sense to migrate an application ...
