STM32 MCUs are not used on any -Arduino boards, so their restrictions aren't as widely known and less straight -forward compared to common Arduino compatible boards. There aren't any standard -pin mappings either. - -General considerations -====================== - -The port is currently designed for and tested with STM32F103xB series -MCUs, but it should work with any STM32F103 series MCUs with minimal -changes. - -Unlike Arduino-based boards, typically there is no automatic reset on serial -connection with STM32 boards. Please use `restart_method: command` with the -STM32F1 port. - -Fixed pins -========== - -When using USB, the PA11 (D-) and PA12 (D+) pins are reserved. The USB -code assumes that PA12 (D+) has a fixed pullup resistor attached to -it. - -SPI uses pins PB13/PB14/PB15, but the pins can be used as general I/O -if SPI is not used. - -Digital I/O -=========== - -All pins that aren't part of the fixed set can be used for digital I/O. Pins are -referred to by their primary name, e.g. `PA1`. Do not try to use Arduino pin -aliases in your configuration. See ST's datasheets for more details. The -[STM32Duino](http://wiki.stm32duino.com/index.php?title=Blue_Pill) wiki has more -info on the popular "Blue Pill" board. - -Analog inputs -============= - -All ADC-capable pins can be used as analog inputs with the same naming as -digital I/O pins. Small packages MCUs (e.g. LFQP48) have 10 channels (PA0-PA7, -PB0-PB1), while larger package devices have 16 channels (PA0-PA7, PB0-PB1, -PC0-PC5). - -SPI -=== - -SPI uses pin PB13 (SCK), PB14 (MISO) and PB15 (MOSI). The clock speed range is -0.15..18 MHz. Chip select pins do not have any restrictions. |
