-# ProfilometerProbe
+# Profilometer Probe
 ## Firmware for profilometer probe
-### Current state:
-After making and flashing, device will begin continuously sending JPEG images using UART
-### Currently in progress:
-Implementing tinyUSB UVC to send JPEGS instead of UART
+
+### 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.
+
+| Name        | Nucleo L432KC | Arducam 5MP Plus |
+| ----------- | ------------- | ---------------- |
+| SPI SCLK    | A4            | SCK              |
+| SPI MISO    | A5            | MISO             |
+| SPI MOSI    | A6            | MOSI             |
+| SPI CS      | D3            | CS               |
+| I2C SCL     | D1            | SCL              |
+| I2C SDA     | D0            | SDA              |
+
+You can connect optional Debug LED to A1 pin in Nucleo board.
+
+### 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
+
+### In progress
+
+- Implementing tinyUSB UVC to send JPEGS instead of UART
