Arduino for STM32

As a "rule of thumb", do not leave the ArduinoIDE open and your USB enumerated to an Arduino board. This goes also for Windows when using non-Microsoft com drivers. Bad things will happen sometimes and mess with your head. The internet has numerous stories of such dark skies surrounding Li...

... In the meantime a way around it is to fix the temporary build folder that can be set in the IDE config file. This is so that it won't need to rebuild all the object files with each change. For 10 years I have used the "slow" excuse as the primary reason to upgrade my notebook and I am...

There are identical formfactor cells that are rechargeable

Recently I found an example on net that shows a time interrupt function based on HardwareTimer, that worked as expected on DB. On the other side, the Arduino’s analogRead is ridiculously slow, taking 40% of processing time, and 3% of analogWrite. Opinion and generalized observation: Too many Arduin...

kurtow187: Interesting. However I have multiple IDE installations on Win10 and "no issues noticed." Same (as one would expect) with Linux. Such "extended" compile/link times may be nothing more than Windows "constipation." The Arduino IDE is JAVA-based and each IDE-vers...

Or, one could throw hardware at the problem: https://learn.adafruit.com/adafruit-tca9548a-1-to-8-i2c-multiplexer-breakout In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. The software-only solution is less costly,...

This question has been asked and answered so many times... https://www.stm32duino.com/viewtopic.php?t=1071 https://www.stm32duino.com/viewtopic.php?t=986 ... and more times that I can count on the old forum and on Arduino.cc. https://forum.arduino.cc/t/why-does-even-a-very-simple-sketch-use-400-byte...

Using wire no device can be found and using softwire I get message that mostly all addresses are found.

IMO: STM32duino is not the best choice when doing low-level, low-power projects. As Arduino is created through wrappers and creative coding tricks, it has some inherent overhead. Rather, the better choice would be to toss Arduino'ish thinking and get down to a professional level of programming rathe...

STM32F103 Internals.jpg The STM32F103xx has a matrix internal connection (actually several different buses), flexible but not every internal connection to any external connection. The STM32Arduino core respects the internal matrix. The reference manual RM0008 is the authority. 2.2.1 System Architec...
