Quoted from DickHamill:connect your desktop computer to the wav trigger using a usb cable and the adapter to the 6-pin header you installed above
The FTDI Basic (and other FTDI adapters) have 6-pinout: DTR, RX, TX, VCC, CTS, GND, and a 5v/3.3v selector switch.
Meanwhile, the WAV Trigger 6-pinout: GRN=(unmarked), TX, RX, 5VIN, (nothing) GND=BLK
Are the RX/TX lines actually to be reversed in the cable, or only in usage (TX to RX, RX to TX) ?
Is the FTDI voltage switch to be set to 5v, or 3.3 ?
Once powered up in the LOAD switch position, I flashed the new WAV trigger code.
Then, disconnect the FTDI, disconnect the power barrel plug, connect a speaker to the audio output barrel connector (this speaker works with a PC, and sounds to play through the speaker).
I press the test button and hear nothing. The flash drive contains the entire list of Meteor sound files, as provided on github, first sound file is 001_Spinner.wav, and there is also this file made with the configuration program:
#VOLM -21
#SPKR 1

This file was generated by the Robertsonics Configurator v2.00
for use with the WAV Trigger firmware. It is only required if
you wish to over-ride default settings. You may add your own
The above file "wavtrigr.ini" is located on root folder of the flash card.
I have tried the test button with #VOLM all the way up to 10, no sound.
What else needs to be done for the WAV trigger board, powered, by itself, with a speaker, to produce the test sound?
Next, I see the WAV trigger is being connected, apparently, from the RoyGBev board from the pads marked J7 WAV TRIG 1..6 to the WAV trigger board 8-pads (some of them), just above the FTDI serial pads, and not to the "trigger" inputs.
So, what is the correct wire correspondence from RoyGBev to the WAV trigger board??
Thanks in advance.
Anyone have any idea why no sound? The file
