I'm diving into the LCR fray here. I haven't read all 182 pages, but I have read the past 25 or so. It sounds like the AY-AT board with the rotary encoder is the one to get at the moment. Thanks especially to madires for all his work on this project! It is truly amazing!
I'm fairly new to electronics mods although I have built many projects over the years. I apologize if these questions are so basic.
I want to run the M-firmware, so it looks like I need to make the mods shown here:
https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/msg1286025/#msg1286025
My questions are these:
1. The AY-AT kits that I'm seeing don't have the IR sensor. It's not that I really NEED that, but it would be cool to have. Is there a way to add the IR to that board?
2. The kits that I'm seeing come with a monochrome LCD display. Is it possible to swap out for a color LCD/OLED or is that not recommended at this time? If color is okay to use, which display is best for this application? The ILI9341?
3. I can't tell what ATMega chips are coming with the kits that I'm finding. It looks like maybe a 328P The posted specs are rather limited. Do I need to worry about this? What is the most recommended chip at this time?
4. Likewise, I can't tell what crystal comes with the kits. Is it simply a matter of swapping out for a 20Mhz? The ATMega won't mind? I'm guessing not since the specs at
http://www.microchip.com/wwwproducts/en/ATmega328p indicate that it supports 20Mhz. Just want to make sure.
Thanks in advance for any assistance!
