Hello, I am interested in those Servo Triggers you guys sell but I thought it would be fun to make them myself as it is open source. I have an Arduino Uno here which can program the Attiny84a, no problem, right. My conflict is the code that is provided. It is in .c format. I can open that in the Arduino IDE but cannot get it to compile as it gives me this error:
Arduino: 1.8.11 (Windows 10), Board: "ATtiny24/44/84, ATtiny84, Internal 8 MHz"
D:\Desktop\ServoTrigger\ServoTrigger.ino: In function 'void __vector_5()':

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
My question is how do I allow this code to compile in the Arduino IDE so I can use an Arduino UNO to program these attiny84a chips. Thanks!
That code was written for Atmel Studio, not Arduino. It looks like they are playing some linker games in order to get things to fit in the tiny84. Best bet would be to download Atmel Studio and build it there.
Ok, I got Atmel Studios 7. I opened the solution, it asked me to upgrade or something so I said yes. I do not have a programmer but I do have an Arduino Uno with an ATMEGA328P chip. I uploaded the example ArduinoISP code to the Uno with no code changes.
Now in Atmel Studios, I went to Project>Device>ATtiny84A.
Then, I created an external tool with the arguments:
I connect the Arduino Uno pins 5v, GND, and 10-13 to the ISP pins on the ServoTrigger board.
What happens now is annoying.
System wide configuration file is "D:\avrdude-6.3-mingw32\avrdude.conf"
Using Port : COM3
Using Programmer : arduino
Overriding Baud Rate : 115200
avrdude.exe: stk500_recv(): programmer is not responding
avrdude.exe: stk500_getsync() attempt 1 of 10: not in sync: resp=0xef
This goes on all the way to 10 and just says thank you at the end...
But then I remove the 10uF cap, it works. But sometimes it does work with the capacitor… It’s confusing. Sometimes I also need to click the Arduino reset button while uploading. Then it uploads. So just hitting the reset button on the Arduino fixes that problem. BUTTTT the next problem:
Once getting it to upload I get this:

Double check chip, or use -F to override this check.
avrdude.exe done. Thank you.
I even override the check with -F and it uploaded again just without the check. It still seems to have not programmed the attiny84a though… So I am lost.
Turns out, there was a short on the SCK pin. dunno how or where. I also had a second board, the 16MHZ SMD clock was not soldered on correctly… (My first time with SMD) The third board I think I just locked up with the fuse bits. Oops, luckily I bought 9 extra Since I knew I was going to screw up. Anyways, I got it to work as long as I solder a lot nicer and use the Arduino IDE to burn the bootloader fuses then use CMD to flash the compiled hex code.
