In order to use the sound feature on the new KISS ESC32A you will need this tool
Start the Editor (as a Chrome App it needs prior installation), select the firmware you want to embed the sound and flash the ESCs afterwards.
You will need to upload 8 or 16bit WAV files which will be converted to 8bit/8kHz.
Replace the sound files by some of your own taste. Atm. the firmware can contain max. 12 sounds at an overall total length of 9.12 seconds and are played as follows
The above examples are used for status messages and will be played in this order.
1 and 2 = messages about used hardware after plugging in the lipo
3 and 4 = status messages after arming/disarming
5 – 7 = messages about the used protocol
8 = fill word to complete the message like “Dshot detected”
9 – 12 = possible remote controls
So a sequence could sound like this:
”Hello World”  “Let’s fly”  “Cool stuff”  “incoming”  “Ready to Rumble”
 “Yeeeha!”  “Oh, Really?”
Tip: Take simple voice or music samples, keep/cut them as short as possible to minimize file size. Avoid sounds or music with too much complexity or noisy backgrounds.
