prerequisites: install ST-Flash utility.click Load Code (or press F8) to flash the firmware.click Build Target (or press F7) to build the firmware.if you are asked to install missing packages, click Yes.in Keil uVision, open the sideboard-hack.uvproj.press the 'PlatformIO:Build' or the 'PlatformIO:Upload' button (bottom left in vscode).open the folder in the IDE of choice (vscode or Atom).To build and flash choose one of the following methods: Method 1: Using Platformio IDE To unlock the flash, check-out the wiki page How to Unlock MCU flash. If you have never flashed your sideboard before, the MCU is probably locked. The 3V3 can be either obtained by connecting the pin to the ST-Link programmer or powering the sideboard with 12/15V. Connect GND, SWDIO and SWCLK to your ST-Link V2 programmer. On the sideboard, there is a debugging header with GND, 3V3, SWDIO and SWCLK. Of course the firmware can be further customized for other needs or projects. VARIANT_HOVERBOARD: In this variant the sideboard is communicating with the mainboard of a hoverboard using the FOC firmware repository.An RC receiver with iBUS protocol can be connected to the AUX serial Rx pin (see schematic) VARIANT_HOVERCAR: This variant can be used for Hovercar build.VARIANT_DEBUG: In this variant the user can interact with sideboard by sending commands via a Serial Monitor to observe and check the capabilities of the sideboard.This firmware offers currently these variants (selectable in platformio.ini or config.h): The MPU-6050 pinout and orientation of axes is shown in the follwing figure:įor more details see the MPU-6050 datasheet and MPU-6050 registers. Interrupts on gesture events such as Tap on all axes or Orientation change.Accelerometer and Gyroscope raw data output.The MPU-6050 determines the board orientation by combining a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die, together with an onboard Digital Motion Processor™ (DMP™), which processes complex 6-axis MotionFusion algorithms. The sideboard brain is an STM32F103C8T6 with the pinout shown in the follwing figure:Ī very important component of the sideboard is the IMU MPU-6050 from Invensense. Below the pinout of the LED boards is shown. The LED boards consist of colored LEDs (blue, red, green, orange) used for design and to inform the user about the current hoverboard state. On the back of the board, two Photo Interrupter Optical Switches can be found, originally used to detect if a human is standing on the hoverboard. Additionally, two ports are used to connect to the LED boards. The original sideboard hardware supports one 4-pin cable that originally was connected to the hoveboard mainboard. ► If you have a GD32 sideboard check-out the repo hoverboard-sideboard-hack-GD The hoveboard comes with two identical sideboards that can be flashed with this firmware. This repository implements the firmware for the hoveboard sideboards.
