So i have been working on the talkie walkie and this time around, I have done something totally different. I am using a different SI5351A module and a different LCD screen. And here in lies the problem. To many changes at once and none of them wanted to work out the bag. Firstly I normally use a 16×2 lcd and I2C backpack. Cannot fit that in the case so its an 8×2 and regular parallel connection. Second thing is I used the Eat A Fruit style si5351, where i normally used the ones from QRP Labs and the drama there is the different crystals used and the fact that I was still using a very old version of the SI5351 library. So i upgraded it, and broke all my code, fixed all my code and now it actually works. Oh one last thing about the LCD, seems there are 2 different types of 8×2’s one with 16 pins and one with 14 pins. I think i smoked the 16 pin one, before my PSU went into current limiting. Not sure what the deal is, but anyway, after much messing around, this part of the project is actually working.
