# HapGrab
## 1. Description
- Interface for Grab-and-move 3D interacetion and haptic feedback
- [Video Demo](https://vimeo.com/784200640)
## 2. Features
- Bluetooth Serial (Send and receive data) [[1]](#1)
- Get and calculate flex sensor angle value [[2]](#2)
- LCD display control [[3]](#3)
- 6DoF Acc/Gryo Sensor
- Haptic feedback [[4]](#4)
- 3D Generative art on openFrameworks
## 3. Specimen
### 3-1. Hardware
Check out fritzing file for more information.
- ESP32 Dev Module (runs on 3.3V)
- ILI9341 TFT LCD Display
- Flex Sensor
- Qwiic 6DoF LSM6DSO
- Lilypad Vide Board
- ~~Qwiic Haptic Driver DA7280~~
### 3-2. Power Module
- 18650 Li-ion Battery
- Li-ion power module
- DC/DC Stepup module
- Toggle switch
### 3-3. Software Requirements
- TFT_eSPI library (by bodmer) modified for ILI9341 and ESP32 (this project) [Go to repo](https://github.com/chanulee/TFT_eSPI)
- Qwiic 6DoF LSM6DSO Library [Hookup Guide](https://learn.sparkfun.com/tutorials/qwiic-6dof-lsm6dso-breakout-hookup-guide)

## 5. Memo / Trial & Error
- Set to ESP32 Dev Module in IDE.
- Button on right side of the microusb port should be pressed when uploading code. Press the other button to reboot after uploading.
- You should set COM port as "send" on the device when you connect to ESP32 (Windows).
- Quit openFrameworks app (ofApp) that gets serial data before uploading data to ESP32.
- Haptic feedback of LilyPad Vibe Board feels a little bit weak on wrist. But still stronger than Qwiic Haptic Driver DA7280.
