Hi Ioannis,

Well the program is an example provided with the software compiled for 628A (I believe):
“
loop:
High 0 ' Turn on LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds

Low 0 ' Turn off LED connected to PORTB.0
Pause 500 ' Delay for .5 seconds

Goto loop ' Go back to loop and blink LED forever
End
“

And the schematic is simple and the circuit works fine with “readymade” code so I guess its ok.

Thanks.
