Arduino for STM32

Hello all,

Just to update on this issue. I have solved it already. It seems I missed out to provide modifications on my LMIC library. Problem does not occur beause my my operating system. The cause of the stall is when the program is trying to connect with the LoRaWAN network server. I just add the ...

I have modified it on stm32CubeProg.sh

I added p=none:

${STM32CP_CLI} -c port=${PORT} p=none ${MODE} ${ERASE:+"-e all"} -q -d "${FILEPATH}" ${ADDRESS} "${OPTS}"

I received this error message:
-------------------------------------------------------------------
STM32CubeProgrammer v2.10.0 ...

The program compiles now. I uploaded it using Upload Method: STM32CubeProgrammer(Serial)

It got some issues on running the program:

Maybe because of the default port setting. I wonder where can I modify it. I need a parity bit of "none". Thanks for your help ...

STL C++ abs() is as described in this link:
https://en.cppreference.com/w/cpp/numeric/math/abs

so as stated by the log: abs(uint32_t) does not exist.
Simply cast like that:
return (abs(((long long)getEpochTime() - (long long)inReference)))

Moreover subtract 2 unsigned number is not advised ...

This variant I make is also the one I use in the deprecated stm32 core version 1.5.0.

I want to update it now to the official stm32 core, but I think I need to edit a lot of things, maybe I have more dependencies on that earlier version. I appreciate your help with this.


I've made a PR with ...

The variant_generic.h error has been resolved. I use the guide sent by ag123 . However I got some new errors coming from RTC and LowPower.

In the old version, my firmware use stm32duino Low Power & RTC ver. 1.0.3, now I upgraded to the latest version 1.2.0.

What do you think is the problem here ...

You should not create new directory, your variant should be added in this folder:
https://github.com/stm32duino/Arduino_Core_STM32/tree/main/variants/STM32L0xx/L072R(B-Z)T_L073R(B-Z)T_L083R(B-Z)T

The L0 hal conf is also not correct as you duplicate it.

The PR example provided by @ag123 should ...

And the change made in the boards.txt? As your issue seems linked to wrong entry.

I already git push the boards.txt. Kindly refresh the repo.

I follow your suggestion to use the official and updated Arduino STM32cores. I also make my own variant. I editted the boards.txt to have it on my board menu. I receive this error. I wonder how to fix it. Thanks in advance.
