# Profilometer Probe
|
|
|
|
|
## Firmware for profilometer probe
|
|
|
|
|
|
|
|
|
|
### Build
|
|
|
|
|
|
|
|
|
|
- Build using Makefile inside root folder
|
|
|
|
|
- Flash onto hardware using flash option for make command `$ make flash`
|
|
|
|
|
|
|
|
|
|
### Supported HW:
|
|
|
|
|
- Nucleo L432KC
|
|
|
|
|
- Arducam 5MP Plus
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### HW Setup
|
|
|
|
|
|
|
|
|
|
Before running code, connect camera module to microcontroler through pins described in .ioc file (open with STM32CubeMX) or in table below.

### Usage
|
|
|
|
|
|
|
|
|
|
- After turning on device, it initializes camera module and starts to capture JPEG images and continuously sends them through UART.
|
|
|
|
|
|
|
|
|
|
- Currently only supports JPEG images in resolution 320*240
|
|
|
|
|
|
|
|
|
|
- UART Baud Rate is set to 115200 Bits/s
|
|
|
|
|
|
|
|
|
|
### Test Script Usage
|
|
|
|
|
|
|
|
|
|
- Build test app using provided Makefile and then run the executable
|
|
|
|
|
|
|
|
|
|
- App will then start saving files received by uart to filesystem
|
|
|
|
|
|
|
|
|
|
### In progress
|
|
|
|
|
|
|
|
|
|
- Implementing tinyUSB UVC to send JPEGS instead of UART
|
