I receive the error "NODE_F207ZG not found" when using Nucleo-L552ZE-Q board and can not work around this error.
i am running this board as a Nucleo-144 in the IDE. The same programs runs on the following boards without a problem: Nucleo-F401RE, an Arduino Mega 2560, and the Ada Fruit Grand Cental. There is nothing, i can find on the web regarding this messa...
i2c clock; how to config ?
in RM0008 Rev 21page 775Bits 5:0 FREQ[5:0]: Peripheral clock frequencythe description of the frequency divider is extremely unclear. there is no formula for where the input is, how it is divided, where the output is. what if I want to set strictly 50...

On the STM32U5xx, keep ADCx->CCR PRESC = 0, do not use the prescaler.
I'm using the ADC1 and ADC4 with PLL as kernel clock (MSIS 24MHz pll'ed to 32768 Hz watch crystal / 2 x (11 + 2163/8192) / 24) = 5.632 MHz). The ADC1 in combination with the MDF "looses" every second sample. The ADC4 never gets ready. The errata shee...
Nor-flash external loader problem.
Hi,I followed the "How to create an external API loader MOOC" videos and after some struggle I managed to get it working for a board using the H7 with an Infineon S25FL127 memory.When I tried to do the same using a board with the G4 and with the same...
