Hi.I have a big buffer with Chirp data for testing that about 30000 of int16 length and I can not get right result from FMAC IIR filtering operation. The operation configured in polling for read and write.I calculate a bandpass IIR DF1 filter coeff w...
My data has zeros every 2 bytes.it's like this: 0x55 0x55 00 00 0xaa 0xaa 00 00 0x33 0x33 00 00 ......I want to remove these zeros with address increment feature of DMA.I wrote a configuration for stm32f107 DMA and removed these zeros without problem...

what is the meaning of this line in bootloaders?
if
(((*(__IO uint32_t*)StartAppLocation) & 0x2FFE0000 ) == 0x20000000)
Thank you.

I use STM32F4
I set MCO1 to PLL Clock and set output prescaler to 5 and I have 6MHz on my MCO1.
There is no problem in it, But when I enable LSE with HSE together, I have no signal on MCO1 pin.
Code:
...
I changed the code to work with interrupt and I think the read and write to/from FMAC is ok now void HAL_FMAC_OutputDataReadyCallback(FMAC_HandleTypeDef *hfmac)
{
ptrOut+=100;
loadedToBuf_O=100;
HAL_FMAC_ConfigFilterOutputBuffer(hfmac,ptrOut,&l...
Thank you. I will test it. Before test I have a question and that is when I trig the Timer faster than the DMA operation, Is there any problem? for example, one data transfer with DMA take 10n Second and the timer trig in 5n Second, So how many times...
Ok. I think I understand what you said. I have never used this mode for memory to memory operation.The data buffer is large and triggering DMA with timer will take a long time, I think. Also I am worried about DMA with ultra fast timer triggering tha...
