I have a mini pro 3v3, 8mhz that i wanna use as icsp to program a 328p that has a 20mhz running. the 328p is running at 5v and has miso, mosi and rst connected to a level shifter to the mini pro.
Now my biggest problem is the programming. From what i have seen you should add 10uf to the mini's reset so it won't reset right? but i found some tutorials that did not do that. What do i do? Also i heard that you have to burn the bootloader because it sets the fuses correct? Another thing is that is has to be modified so it knows its running at 20mhz because it wont work if i dont.
I saw a tutorial where they programmed a 328p standalone using a uno, he presses shift "upload using programmer". But the configuration at that time is set to the uno or mini in my case. So how do i let the IDE know that it has to take in mind that the 328p is running at 20mhz?
hope this makes sense.
