Re: Board pinout editor

... I want to create an association specific to a single project I'm working on, not the generic pinout. Then I will use a printout of that PNG as a guide to solder the right wires to many boards Maybe something like in main.ino: #include "./MyPinDefs.h" in MyPinDefs.h (a Tab of main.ino)...

Re: Blue Pill running slow

Another resource is the stm32-base.org pages. Thanks to tomtom381 About The purpose of the STM32-base project is to provide you with a simple and easy to use base project for working with STM32 microcontrollers. More information on why this project came into being can be found on the about page.

Re: WHICH CORE?!

Hi the question is simple but the answer is hard: which core? official or Roger's core? Not hard: Official is the professional choice with STM Corporate support. Core built on their professional libraries. Official core provides a supported codebase beyond ArduinoIDE if needs require a migration pa...

Re: charging lipo batteries

Charging li-ion algorithm is pretty simple and you can find it on many web sites. ... Yep, that is what ag123 was saying by giving the PDF documentation for the algorithm + flowchart. No doubt, it is straight-forward and the dedicated IC's are cheap, but my point is if your power requirements match...

Re: charging lipo batteries

LiON is good if a management IC is incorporated and such logic could be managed by a microcontroller if the uC is awaken periodically to monitor the remaining charge. However, I have been using LiFePO4 for years and no overly complex charging regimen is required. They can be float-charged! This mean...

Re: Blue Pill running slow

Thank you so much Ray. I've spent the last couple of days following the links that you gave - and then the links from the links - and then the links from the links from the links..... You are welcome. I' am old-as-dirt and my style is the same: old school; so I rarely directly answer, preferring to...

Re: Moving at a snail's pace....

... In this millenium I've not done much programming but after retiring I discovered that there was only so much plumbing, carpentry and gardening that I could cope with and looked for something more challenging. I decided to try to integrate my Nikon DSLR with a home-made LED flash with some extra...

Re: How to use STM32 boards with Arduino IDE and how fast ESP32 vs STM32 are they? (incl. surprise)

... the hard part is always the calibration. unfortunately, a lot of times, after calibration, what would normally be done is to make tables out of them so as to use cheaper mcus without an fpu and perform (linear) interpolation to tell the values, in particular as most sensors do not require micro...
