I am generating what I believe to be the correct frame sync pulses too. I'm connecting to the wrong inputs on my scart lead? Everything I've read shows this as being correct though.Can someone check if I calculated the correct values to use at 3volts? How accurate do the voltage levels need to be? I chose the closest standard values, is this accurate enough? I'm using the wrong resistors to mix the signal.How accurate does the timing need to be? I'm using the timer interrupt on the PIC to start each line 64uS apart. I've posted the diagram at the end of this post showing the timing on the two pins for my test and as far as I can tell I'm generating the correct sync timing and the other signal is just some stripes for testing. I'm thinking one of three things could be wrong :. I'm connecting to the TV input via a scart lead connecting the video signal to pins 17 and 20 on the diagram on this page.īut I get no picture at all on the TV. The only difference is that my circuit needs to run at 3v instead of 5v due to using a PIC24 so I've recalculated the necessary resistor values and the closest ones I can find seem to be 220 and 470 ohms. )using a similar method to the circuit described half way down this page. I'm trying to generate PAL tv signals using a PIC24FJ64GB002 (datasheet:
