Progression
DTO 1
The workpath of the DTO1 for this sprint is the following:
- Redessign board connections to use ESP-01
- Search for libraries and examples to see how to publish messages
- Develop publisher logic
- Test connection with a mosquitto server
- Test connection with NodeMCU
DTO 2
The workpath of the DTO2 for this sprint is the following:
- Redessign board connections to use ESP-01
- Develop publisher logic
- Test connection with a mosquitto server & Debug
- Test connection with NodeMCU
MQTT Broker
The workpath of the MQTTBroker for this sprint is the following:
- Analysis & documentation
- Subscriber and publisher mocks with mosquitto
- Debug channel for testing
- Subscriber channel for testing
- MCP Led bar
For turning the number into a binary channel representation, it has been created our own representation function using: 2^(n) - 1
The video can be found in the presentation slides.
RPi w/ ChibiOS
The workpath of the Supervision Station for this sprint is the following:
- Analysis & search for documentation of ChibiOS and RPi
- Led blink test
- LCD Screen test
- I2C test
It has been tested the ChibiOS and it has been found that the SDCard given to us had an error. Also, it has been done the documentation for making easy to start developing the Supervision Station in the next sprint. The video can be found in the presentation slides.
