s32duino Core

This is a library for STM32F0 chips.

WARNING: This is still a WIP Project. It probably contains quite a few bugs and I'm not sure if going to continue developement

Chips available:

Supported chips

• STM32F030F4

Getting Started

1. Download the latest version from https://github.com/david-sawatzke/s32duino
2. Unzip it into [Arduino]/hardware folder
3. Install Arduino Zero from the board manager for the arm-none-eabi-gcc compiler

Differences

• There are no pin numbers, each Pin is named according to the datasheet, e.g. PA4, PA5
• Pins have the PinNumber type (If using a library, you can see if it uses an int for pins and just cast it to int. You will get a few warnings, but it'll probably work)
• A double has 64 bits and an int has 32 bits
• Programming can only be done via blackmagic debugging probe

Code Size

As this library doesn't use a HAL, the compiled binaries are comparable to the AVR core:

• Blink: 1956 Bytes
• DigitalReadSerial: 2072 Bytes
• ToneMultiple: 2188 Bytes
• Autoscroll: 3044 Bytes
• ArduinoISP: 4120 Bytes

Troubleshooting

If you have any issue to download/use a package, you could file an issue on Github.
