Axiometa genesis

Collected findings from experiments with axiometa genesis board.

Environment: PC Win11, Powershell, Visual Studio Code
Controller: ESP32-S3
Main board, modules: Axiometa genesis
Programming: Toit jaguar

1. setup controller with Toit jaguar

• Connect USB from ESP32-S3 OTG to PC
• press BOOT button
• flash jaguar: jag flash -cesp32s3 -p COM8 --name GENESIS
• check flashing: jag scan GENESIS

• toit app test-esp
• run example: jag run .\test-esp.toit
  • onboard led blinks slowly
  • if boot button is pressed then the led blinks faster
• monitor output: jag monitor -a -p COM8

2. checking AX22 modules

The main board has places for 8 AX22 modules.
It carries useful information: The GPIO port numbers are printed on the module positions.

The genesis eletronics kit contains more than 20 AX22 modules.
Attention when occupying module space #1: Port 2 is identical to ESP boot button.

first AX22-module configuration

1. ✅ LDR -0005
2. ✅ DHT11 -0011
3. ✅ RGB-Led -0006 *3x LED (RGB)*
4. ✅ TrafficLight -0024 *3x LED (RYG)*
5. ✅ NeoPixelMatrix -0028 *15x RGB*
6. ✅ Buzzer -0012 
7. ✅ KeyboardKey -0027 *1x RGB*
8. ✅ ToggleSwitch -0022

• toit app test-config1.toit tests the modules and prints out results on monitor.
  • run monitor: jag monitor -p COMx
  • run toit app: jag run .\test-config1.toit

Second AX22-module configuration

1. ✅ D-Pad 0016
2. ❌ MicroPhone 0009 ? (total insensitive)
4. ✅ Vibration Switch 0025
5. ToF 0015 VL53L0CX
6. Accelerometer 0030 MPU6050
7. ✅ KeyboardKey 0027  1x RGB
8. ✅ NeoPixelMatrix 0028 15x RGB

• toit app test-config2.toit tests the modules and prints out results on monitor.
  • run monitor: jag monitor -p COMx
  • run toit app: jag run .\test-config2.toit

BLE remote camera

While playing around with the AX22 modules, I came across the VL53L0CX and immediately thought about implementing a smartphone camera shutter. When searching for BLE information, I was overwhelmed by the complexity. Since I had no experience with BLE and wanted quick results, I ordered a small BLE hardware switch BT1818 for my initial experiments.
It took a while, however, before our own experiments bore fruit. Information and tools from nRF, and of course, a particularly clever artificial Frenchman named Claude, were particularly helpful.
The first implementation in Toit test-camera uses only the AX22 keypad module and triggers it at the push of a button.
Start scan on smartphone (it has to support BLE!) and pair BLE Camera. If successful, volume up is sent when the button is pressed, which triggers a photo capture in many camera apps.

The basis for sensor-controlled smartphone recordings is in place and now the various modules of the Axiometa genesis board can be used according to your own inspiration.
