Let me start by saying:Yes I know the STM32 Finder exists, no it doesn't help me find what I needYes I've seen this thread but I do not want to get into manually coding a script to try and find parts if I can avoid itYes I have used the CubeMX and no...

Per the title really - I've just tried to install the Linux version on a raspberry pi running Raspbian / Debian 11.7 'Bullseye' and, well, NOTHING happens.If I click 'SetupSTM32CubeProgrammer-2.16.0.linux' nothing happens at all, if I select "execute...

I have an STM32G071CBTx with a rotary encoder wired to GPIO pins PB5 + PB7 (LPTIM1_IN1 and LPTIM1_IN2), but for some reason it will never count down no matter which way the encoder is turned.I have checked the encoder waveforms and they are as expect...

I'm sure I'm missing something here but for the life of me I can't see it.TIM2 CH1+CH2 are in use as encoder inputs but I believe I should still be able to generate a basic PWM output on CH3 at the same time?Code is all generated by Cube IDE and it r...

Is there any way we can actually stop the Cube from deleting pin names just because we change the pin function?I had hoped that "pin locking" would do it but no, if I spent ages naming all the signals on my MCU to line up with my hardware and then re...

It's not only advanced & GP timers though - LPTIM1 on G071 can do encoder mode but other GP timers cannot - and I've not audited the entire range to see if LPTIMx on other MCU's can do encoder mode or not.The encoder feature seems to be somewhat inco...

Lots of timer channels that have 2-pins are up-count only, for example G071 has TIM1,2,3,4,6,7,14,15,16,17,and LPTIM 1 & 2 but only 4 timers out of that lot can actually work for encoder inputs (TIM1,2,3,4) hence my question.

Well I'm going to answer my own question - by trawling the HAL library, the LL header files and the docs I've arrived at this which does appear to work correctly:/* LPTIM1 init function */ void MX_LPTIM1_Init(void) { /* USER CODE BEGIN LPTIM1_Init ...

Well I suspected that might be the case but it's disappointing that the documentation doesn't make it clearer given how complex the timers are these days.

Thanks for taking the trouble to come back & report on the fix - much appreciated!

STM32 part with the most avialable rotary/quadrature encoder inputs

Can't install V2.16.0 in Debian/Raspbian Linux - installer insta-quits

LPTIM not counting down in encoder mode, always counts up (G071)

G071 TIM2 CH3 PWM output not starting

Please stop Cube from deleting pin names just because I changed the pin function

Re: CubeIDE 1.9.0 has a heart attack on "loading compatible MCU's" - out of memory / huge delay / non-responsive
