Quick question concerning L0 internal EEPROM...From RM0377, page 79:Write to data EEPROM...DescriptionThis operation aims at writing a word or a part of a word in the data EEPROM. The usermust write the right value at the right address and with the r...

... leads to "funny" results:STM32L011 with 16 kB of flash, HAL inits and LED toggle in main, DEBUG, no optimization:93% of flash usedI had not expected it to be that bad! Okay, I will probably not use too much HAL, will use Release version with opt...

Heyho,there's lots of info in the datasheets and the AN2867 about the specs of the HSE / LSE oscillators with passive crystals...But I'd like to have some "measurable" *** specs, so that I can compare a real life custom board, which means:voltage lev...

Heyho,for a new project I need an MCU with 2 channels of 16bit / 50kHz ADC.It looks like the F373's sigma delta ADC (SDADC) might be good enough (it will be calibrated for accuracy anyway).But I haven't found any info about the SDADC's digital low pa...

Heyho,I had probably some race condition, just want to make sure:the buffer switching in DMA's Double Buffer Mode (DBM) (both for DMA and BDMA) occurs immediately with the Transfer Complete (TC) interrupt?So when the DMA's TC ISR is entered (which ta...

UM2407, page 17 - use the MIPI-10 debug connector, but first check the jumper.I have that board, but I haven't tried that!

Tutorials aside, people should read datasheets.In the sensor's DS, I only see a 4k7 pull-up in each schematic.Compare that to the STM's pull-up, so no surprise here.

"This feature is not available for all timers."So I guess each timer has it's own break inputs, and you can probably stop only that specific PWM.

Memory-mapped mode doesn't even work with a clock rate of 20 MHz (or anything else below the 47 MHz mentioned in the datasheet) ?The ringing you see on the scope might come from your scope measurement itself, always use a spring tip for GND, not the ...

Check the datasheet not the RM, search for "PC2".Datasheet of H733, should be the same for H723/H725.See note 4.Even worse, see again note 4 for HyperBus, max freq with PC2 is 47 MHz:Dear ST, this should not be in smallest print in some footnotes, bu...
