Hi,We have now a problem with some boards, H7A3ZI or H743ZI , when switching off : RTC stops working !RTC is powered on VBAT with a standard CR2032 and was working as it should on about 500 boards since more than a year. Now (some) batteries loosin...

Hi,Just yesterday on my H743VIT6 (rev. V ) on the running TFT : picture faded away...white screen.I just happened to look at the display , thinking ...ok, maybe one of the thin wires just broke now...TFT (small, 1,8" , ST7735 on 3,3V) connected /sold...

I have a problem, but dont know, how to solve...when this function ( mp3dec_decode_frame(..) ) is used, get hard fault. ok, but cannot debug , because no step into function is possible, hard fault is always next step.Now the prerequisites : this func...

1. I just can say: with F411, also F4 series, on I2C , with 16b working fine; with 32b - i didnt get it work correct.Maybe chip problem, because sometimes it working correct, most (!) time it puzzled data, sync was in middle of 32b - unusable. (I use...

You will not mess up anything, as long as you start the (circular) DMA - and never stop it.If dont need data....just dont use them, but dont stop the running DMA process.It will be correct until...ever or a strong spike destroys the cpu. If you just...

Hi,>1. read in rm :So you can set here 32b data, but the SPI has only 16b shifter, so it needs 2x load with 16b to send /receive a 32b word. (On "bigger" chips you could use SAI , can set data 8...32 bits. But here only 8...16.)Maybe you could set th...

Why not set the buffer as two dimensional array ?(The DMA dont care about, how you call the members in the array.)Then have A in one and B in other "one line" :uint16_t ADCdata[16][2] ;A in [0..15][0] , B in [0..15][1] .

Right, i seen.But the not working board has a hardware problem...maybe bad solder /contact ...you have to find.
