Both 'U5 ADCs contain the LFTRIG bit; however, I could not find in either 'U5 datasheet the Tidle value above which this bit has to be switched on.JW

In this thread:2nd post by @andy_long (between my 1st and 2nd post) is missing. Note, that in my 2nd post I am quoting from that missing post (> This is only reproducible if it is run continuously for an hour. and > Meanwhile, could you please answe...

Schematics say, it is populated on Rev.B and Rev.E, but not populated on Rev.C and Rev.D:If it is populated on Rev.E, UM1472 fails to mention that in the revisions changelog:And in any case, absence of R31 in Revs. C and D should be mentioned in con...

The STM32G0 ADC calibration in Cube/HAL performs 8 iterations of the calibration process, each time reading out the calibration factor and accumulating it, then dividing by 8 (i.e. taking their average) and writing it back to the calibration factor h...

We have dozens of tags ("labels") e.g. in the STM32 products subforum. This might be an useful tool to select relevant group of posts. However, the window, where the "labels" are selected is too small, displaying only perhaps half a dozen of tags at ...

Write a simple "blinky" (toggle a pin) for the STM32 and observe, whether the "blinking" stops when you attempt to enter the bootloader.Write a simple software which mimics the bootloader, i.e. with clock set to HSI, sets up UART at the expected baud...

As @Tesla DeLorean said above, in 'H7, GPIO access time from processor is dominated by traversal through the many buses and their interfaces. JW

Are there signals on other bootloader pins? Can you program the STM32 in other way (SWD)?JW

How is globalSeconds defined?The most straighforward thing to do is to toggle a pin at the place where globalSeconds is incremented, and observe using oscilloscope/logic analyzer.JW

In 'U5 ADC, what is Tidle value to switch on LFTRIG

Missing (censored?) post

DiscoF4 - is R31 populated on RevE or not?

Why does 'G0 ADC Calibration in Cube/HAL perform averaging in software?

Please make the "Labels" window usable
