## Lab 1: Verification

This lab follows my efforts of flashing, verifying, and interfacing with the hardware kit introduced in Lab 0

### Part 0: Flashing firmware

To begin, I plug in my board to my PC and download the U2F file

Per the instructions, I then hold the boot button and quickly press the reset button. Shortly after, the storage device appears as avaiable with the name `RPI-RPI2`

After simply copying the file and waiting a few minutes, the storage device dissapears, and re-appears with the name `CIRCUITPY` as expected

I can now move on to verify the radio activity functions correctly.
### Part 1: Verify Radio

To get started with radio verification, I power on my board with board in proximity with my classmate Gatlin. My board is on the left

#### Send

After downloading and copying the send code I test this out by pressing the power button on my device. I can verify success by seeing the other board light up with the LED

#### Receive

I then copy the receive code to my board and open up the python serial connection (process elaborated on below)

On Gatlin's board, I press the power button a few times. The results here show success, as the LED color changes between red, blue and green, and packets are shown to be received in the python terminal.

### Part 2: Serial Console

To verify serial access capabilities with my featherboard, I will be following the linux instrutions provided

#### Determine the port

With the board connected, only one serial port appears. This is a good start

![port-check](./port-check.png)

#### Connect

I now run the `screen` command on the serial port with the baud rate given from the tutorial

![screen-cmd](./screen-cmd.png)

This is successfull, and I drop into the circuit python interpreter with ease!

### Reflections

The overall process here of interfacing with the RP2040 featherboard and basic interactions with the radio and python interpreter were straightforward. This is convienent compared to my prior experience with embedded controller, and the need to often compile and push lower-level code to build features.
