I have a small application, but I have over a 100 texts. Quite a few are duplicates. But even without duplicates it's a lot of scrollingIf I want to change the translation of a word I would need to scroll through the list manually. It's easier if I c...

I have a text field that's left aligned and rotated by 270 degrees so that the first character is at the bottom.If I change the language where the text is longer the first character shifts down.This is not what I expect.I expect that a text that is ...

I have an idea:Use a us precision timer to create a pulse on a GPIO pin at a precise interval. For instance 1.000001 secondConnect the output to the timestamp pin.Start the timer and clear the rtc at the same timeLog the raw timestamp data from the t...

It looks like a 6-axis sensor with a separate magneto sensor. There are 9-axis sensors that feature build-in sensor fusion that might be better.My smartphone compass sucks. I frequently have to calibrate it and sometimes it points in the wrong direct...

Not a direct answer to your question, but one possibility is to get the timestamp with a regular timer and combine it with the RTC to calculate the subseconds part yourself.In the past I made a data logger that used a sub milli second timer to log ev...

That's going to be difficult, because I use a custom board. I do have a development board (STM32H735G-DK), but this one doesn't have a USB-A receptacle. I can strip the code I have right now, but pins might be different. Is that ok?Also the problem i...
