6.7.0. STM32H745 doesn't have "Power Regulator Voltage Scale 0" in the list

2022-12-10
I selected LDO power supplyBut frequency is still limited to 400MHz.

SOLVED!!! BUG IN DOCS!!! ETH Transmit Ring Buffer doesn't wrap around (STM32H745ZI)

Issue is that:ETH->DMACTDRLR, // Channel Tx descriptor ring length register (ETH_DMACTXRLR)ETH_DMACTDRLR_TDRLopened a bug:https://github.com/STMicroelectronics/STM32CubeH7/issues/198current description:TDRL[9:0]: Transmit Descriptor Ring Length This ...

STM32L151VE ADC reads 20% lower value on one of the ADC inputs (channel 18, pin B12)

2019-03-13
Not sure if I messed something up. Signal is okay (on the pin). No differences with layout compared to other inputs. ADC is at full speed (16 MHz).On image it is sensor 22 (reads ~2500). Sensor 23, 24, 25 all read normal values (~3000).Voltages on al...

STM32L151VE ADC in sequence reads higher value for the 1st rank

2019-03-13
ADC consistently reads higher value for any channel which is 1st in the sequence. If I query this channel 2nd time as rank 2 (immediately after high value) then it reads normal value. Value is high by about 10%.Tested on stable input many-many times....
