Coding Dojo - The learning remote control
The document outlines a coding dojo session focused on developing firmware for a learning remote control using C++. It details the agenda, expectations, and specific requirements for coding exercises, including signal detection and pattern recognition. The session emphasizes collaboration in a non-competitive environment, with structured practice and reflection segments.
Coding Dojo - The learning remote control
- 1.
- 2. Coding Dojo Mindset ● We are here to learn ● Safe place outside of work ●Need to slow down ● Focus on doing it right ● Noncompetitive, collaborative, fun environment
- 3.
- 4. Agenda ● 19:00 19:10 Introduction ● 19:10 19:30 Intro ●19:30 20:00 Practice Session Part 1 ● 20:00 20:10 Break ● 20:10 20:45 Practice Session Part 2 ● 20:45 21:00 Retrospective
- 5. The learning remote control ● You are writing the firmware for a learning remote control. ● You put it into a 'listening' state... ●...to capture the signal from another IR remote control ● Your firmware must find a repeating pattern of pulses
- 6.
- 7. Other requirements ● on_start_learning_mode to simulate the user initiating a training operation ● on_signal_change called repeatedly to simulate a continually repeating input signal ●Return a list of pulses representing the detected pattern (or none)

- 11. The following will hold true ● The first invocation of the on_signal_change method will be the start of the pattern. Note that nanos_elapsed will be 0 for this first call. ● The first invocation of the on_signal_change method will always be for a LOW to HIGH transition (rising edge, is_high is True). ●The pattern will be made up of at least 1 HIGH/LOW pulse. ● The pattern will be made up of less than 26 HIGH/LOW pulses. ● The pattern will be made up of ideal pulses (i.e. no jitter, fuzzyness, or drift).
- 12. Practice session ● One laptop with a functional dev. env. is connected to a projector ● Two developers pair program on the laptop. The others are watching the code changes. ●Every 7 minutes, one developer leaves the laptop and the next one from the room takes his place.

- 14. Retrospective ● What surprised you? ● What happened as expected? ●What do you plan to use at work?
