# New Firmware! Now with actual current sensing!
|
|
This firmware is much better than the old one. tested up to 40A / 60V, no dead board so far :)

## Hoverboard-Board-Hack
|
|
|
|
This repo contains open source firmware for generic Hoverboard Mainboards.
|
|
The firmware you can find here allows you to use your Hoverboard Hardware (like the Mainboard, Motors and Battery) for cool projects like driving armchairs, person-tracking transportation robots and every other application you can imagine that requires controlling the Motors.

#### Hardware
|
|
|
|
|
|
The original Hardware supports two 4-pin cables that originally were connected to the two sensor boards. They break out GND, 12/15V and USART2&3 of the Hoverboard mainboard.
|
|
Both USART2 & 3 can be used for UART and I2C, PA2&3 can be used as 12bit ADCs.

|
#### Flashing
|
|
To build the firmware, just type "make". Make sure you have specified your gcc-arm-none-eabi binary location in the Makefile. Right to the STM32, there is a debugging header with GND, 3V3, SWDIO and SWCLK. Connect these to your SWD programmer, like the ST-Link found on many STM devboards.
|
|
|
|
Make sure you hold the powerbutton or connect a jumper to the power button pins while flashing the firmware, as the STM might release the power latch and switches itself off during flashing.

#### Examples
|
|
|
|
Have a looh at the config.h in the Inc directory. That's where you configure to firmware to match your project.
|
|
Currently supported: Wii Nunchuck, analog potentiometer and PPM signal from a RC remote.
|
|
If you need additional features like a boost button, have a look at the while(1) loop in the main.c
