The voltage i applied was within 4.8v to 5v for both crystals. i dint bypass capacitor. I fixed it the same was it was in the circuit diagram. But what i observed was that with the 20mhz crystals, pin 9 and 10 was reading 0.95v while with 3.5mhz crystal it was reading 0.65v and 0.95V
Hi, please am new in this forum. I tried the pure sine wave inverter on breadboard but not working with 20Mhz crystal. when i use 3.5Mhz crystal, it worked without connecting to the transformer. i have bought several 20Mhz crystal but still gave the same result. i programmed the pic using the...
