I addition to Micha's question, I have several others that really affect how well the emulator can assist Lua app development.
1. Beyond just playing audio files, it appears that AudioFileBox control shows no audio files to browse for, despite the fact that there are audio files in the Audio and Audio/<lang> directories for the emulator.
2. Is there a way to simulate sensors and telemetry from those sensors (perhaps from telemetry downloaded from an actual flight log on a real TX)?
simulating Sensors or Telemetry with DS-24 Emulator in JetiStudio is easy done. Program P1 or P2 Movement as Input Signal in Lua. Give a short look at Jetis 09_input.lua Example. You will find this in Jetis Lua API.
Not quite the same . The input signal is just ONE PART of the overall whole -- also need representation of the sensors as it would appear on the real radio (i.e. the RPM or current sensor from a Mezon 90, or the relative altitude from an MAlti, etc.) so that we can test the form interaction of picking the sensor, having the output from that sensor, etc.
In short, I want the emulator to behave more like a "real world" TX, using, for example, the log data from a prior real-world flight.
