Re: 73 de SP5IOU

Welcome. While the "old" forum and this carry the same STM32duino.com URL, they are separate sites. Roger's old site crashed and could not be completely recovered. It is now STM32duinoforum.com This site is hosted and managed by STM Corporate; Frederic is the primary admin. Magic Morse: https://www....

Re: yet another issue, really sorry PWM related.

... PB1 4 5 work correctly, those are on Green and blue leds, PA11 PA15 are on red. It might be that the leakage voltage is just enough to keep the reds lit and the green and blue not lit.... ... I dunno... or its just those pins. LED Vf.jpg Normally, I use the output port pin to "sink" the LED wit...

Re: i2c MPR121, Need help trouble shooting whats wrong...

... I dunno because i resoldered this chip a few times from transferring off the other boards maybe I cooked it :/ Clearly you are working at a high-level of prototype assembly (nice board BTW.) I hope my comments regarding lib testing did not offend; too often I go off-track with a generalized tea...

Some working examples w/ caveats:

They compile error free on Roger's core, I do not guarantee them to work as

Sadly normal functions dont appear to be working as when i try to run my project the project hangs for up to 30 seconds during the wire begin stage... it ether hangs for good or or might start the rest of the program. ... ...

Re: Variant.h pin definitions unclear?

The variant file you linked to defines A2 #define PA4 A2 ... which just means if someone codes A2 (Arduino-centric) as a pin_name the preprocessor translates that to PA4 (proper name) STM-401.png Have you followed the wiki on building a variant? It is a good guide to how files are "glued" together. ...

Re: EEPROM emulation how to increase size?

If using STM's official core: https://github.com/stm32duino/wiki/wiki/API#EEPROM-Emulation If using libmaple (Roger's) then search the old forum or consult the Example: https://www.google.com/search?&q=eeprom+site%3Astm32duinoforum.com ... and you can search this forum in the upper-right Search box.
