# Hardware Bring-Up Checklist
|
|
|
|
## ESP32 Cargo Controller
|
|
|
|
### Compile
|
|
|
|
* Firmware compiles successfully
|
|
* Required libraries installed:
|
|
|
|
* ArduinoJson
|
|
* OneWire
|
|
* DallasTemperature
|
|
|
|
### Upload
|
|
|
|
* Board: ESP32 Dev Module
|
|
* Serial monitor opens at 115200 baud
|
|
* Boot message appears
|
|
|
|
### WiFi AP
|
|
|
|
Verify ESP32 creates AP:
|
|
|
|
* SSID: XterraController
|
|
|
|
### HTTP API
|
|
|
|
Test:
|
|
|
|
```
|
|
http://192.168.4.1/status
|
|
```
|
|
|
|
Expected:
|
|
|
|
* JSON response
|
|
* Battery placeholder values present
|
|
* Relay states present
|
|
* Sensor health present
|
|
* Network status present
|
|
|
|
### Relays
|
|
|
|
Test endpoints:
|
|
|
|
```
|
|
/relay/starlink/on
|
|
/relay/starlink/off
|
|
/relay/fridge/on
|
|
/relay/fridge/off
|
|
```
|
|
|
|
Verify:
|
|
|
|
* GPIO16 controls Starlink relay channel
|
|
* GPIO17 controls Fridge relay channel
|
|
* Relay logic is correct
|
|
* If relay behavior is backwards, update relay active-high/active-low logic
|
|
|
|
### DS18B20 Sensors
|
|
|
|
Verify:
|
|
|
|
* Sensor bus initializes
|
|
* Missing sensors do not crash firmware
|
|
* Connected sensors report temperatures
|
|
* Sensor fault state works
|
|
|
|
### UART
|
|
|
|
Verify:
|
|
|
|
* UART initializes
|
|
* ESP32 does not crash without Pico connected
|
|
* Serial JSON protocol works once Pico or USB-UART test is connected
|
|
|

## Pico Dashboard
|
|
|
|
### Pico Boot
|
|
|
|
Verify:
|
|
|
|
* Pico 2 W boots
|
|
* MicroPython or CircuitPython environment works
|
|
* Main script runs
|
|
|
|
### Display
|
|
|
|
Verify:
|
|
|
|
* ST7796S initializes

|
* Screen fill works
|
|
* Text drawing works
|
|
* Rotation/orientation is correct
|
|
|
|
### Touch
|
|
|
|
Verify:
|
|
|
|
* FT6336U initializes
|
|
* Touch events are detected
|
|
* X/Y coordinates match screen orientation
|
|
* Bottom navigation zones match expected touch positions
|
|
|
|
### Buzzer
|
|
|
|
Verify:
|
|
|
|
* Active buzzer turns on
|
|
* Active buzzer turns off
|
|
* Buzzer does not block UI loop
|
|
|
|
### UART to ESP32
|
|
|
|
Verify:
|
|
|
|
* Pico sends status request
|
|
* ESP32 responds with status response
|
|
* Pico parses response
|
|
* Pico updates app state
|
|
* Pico sends relay command
|
|
* ESP32 toggles relay
