 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

I have all the NUCLEO's Peter has published code for and am trying my hand at creating some PCB's for the L431 but struggled a bit when it came to determining just what functions are available on what pins for the different varients. Accordingly, I have taken all the pinout information I could glean from different threads and merged into a single document. 2019-03-07_151051_STM32L4_Pin_Designations.pdf I have not yet confirmed these are absolutely correct but would appreciate any feedback if I have made any errors in translation from Peter's threads. panky. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

A 2nd question if you don't mind me "tagging it on" IF you're not using the RTC function of the L431 do you actually need the 32.768Khz Crystal? |

The Armite L4 uses the 32KHz clock to discipline the main RC processor clock. Without it the main clock will go to an extreme and timing of things like DS18B20 will be wrong. TIME$ will not work and all TIMER counts will be inaccurate. UARTs and I2C will work as they use a separate clock. |
