Texas Instruments C614 Synthesis Code

To continue, click on the Run Internal icon again. The LEDs should flash during MELP synthesis (Extra, extra, read all about it) and should flash in a different pattern after MELP synthesis.

The MELP1 program can run on either the demo box or the code development board. The latter has only two switches (SW1 and SW2) while the former has ten switches (SW1 to SW10), four LEDs, an LCD, an EPROM socket and a flash card socket.

Upon power-up the 614 should say Extra, extra etc and the LEDs should flash in alternating pairs. When the LED pattern becomes a rolling one the program is sitting in a loop and scanning SW1 and SW2. Pressing SW1 launches the MELP synthesizer into 11 character phrases. Pressing SW2 begins a more complex sequence of events. One MELP phrase is synthesized and then the 614 goes into midsleep mode (the LEDs will cease flashing). This sleep mode can be exited by pressing SW1, after which another character voice will be synthesized. Finally, if an EPROM is plugged in and it contains MELP speech data (at address 0x0000) then this data will be synthesized before the program returns to the tight keyscan loop.

At any time during speech you can press one of the port F keys (SW3 to SW10) to skip to the next phrase. This feature is not available when running the code on the demo box.
