## Summary:
This repo contains the "Hardware" files to support STM32 based boards on Arduino version 1.8.x (some older versions may also work) including [LeafLabs Maple, and Maple mini](http://www.leaflabs.com/about-maple/), and other generic STM32F103 boards.

## Background & Support:
* Based on https://github.com/bobc/maple-asp, which is in turn based on LibMaple by Leaflabs
* **Please read the wiki (https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki) for full details**
* See also my blog: http://www.rogerclark.net/stm32f103-and-maple-maple-mini-with-arduino-1-5-x-ide/
* **NEW: Main support site for using STM32 boards with the Arduino IDE: http://www.stm32duino.com/**
* Original LeafLabs "Docs:" http://docs.leaflabs.com/docs.leaflabs.com/index.html

## Known issues
* Use of static variables inside functions greatly increase the code size becuase additional code is needed for thread-safe handling of these statics.
If this is a problem for your application, please edit platform.txt and add -fno-threadsafe-statics the compiler.cpp.flags

## Purchase info:
### Entry level boards
* [Ebay search for "arduino maple"](http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_BIN=1&_nkw=arduino+maple&_sop=15) (currently costs <$5 with shipping)
* [AliExpress search for "leaflabs maple"](http://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20150607085526&SearchText=leaflabs+maple)

### Bigger boards (You need to load the stm32duino bootloader)
Some suppliers have this board e.g.
* [ STM32F103VET ](http://www.ebay.com.au/itm/1PCS-STM32F103VET6-ARM-STM32-Minimum-System-Development-Board-Arduino-M77-/301433302819)
* [There is also a STM32F103ZET board which also works, however they are not always available. They have been listed as "STM32F103ZET6 Minimum System Development Board ARM STM32 Cortex-m3 M75"](http://www.ebay.com.au/itm/1pcs-STM32F103ZET6-Minimum-System-Development-Board-ARM-STM32-Cortex-m3-M75-/291305557264)
