Demo mode working!
Leds working!
When switch the circuit on Normal mode … i hear the sound “Ready”!
My problem appears when i try to connect the SpeakJet IC with Serial Interface.
When i send the following commands (in linux concole) to test the serial connection i hear randomly beeps, passes:
echo “\0” > /dev/tts/1 (serial control mode)
echo “V” > /dev/tts/1 (Ready test)
echo “X” > /dev/tts/1 (out of serial control mode)
I can’t hear the “Ready” sound and nothing worthwhile…
My serial connectivity configuration is: 9600 baud, no parrity, 8bits 1 stop bit
Not much activity over there. If you were connecting to a BB II, you might get more help here. But not many Linux (or Speakjet, for that matter) posts here.
But, I connected the RCX line to PC serial cable only once for test.
I hope I did not destroy the SpeakJet! Demo mode and the other functions still works…
It appears that you have wired the DB9 plug wrong. Pin 5 is the ground, and it should be on the other side of the plug. I do not know if the thing will be able to use the raw RS-232 voltages from the PC, but it’s wired wrong for sure.
Even if you don’t intend to stack it on top of an Arduino, it is easily connected to whatever you want. I bought one after getting my breadboard working!
