Re: Trouble programming a ATMEGA88P with Arduino Mega 2560

I checked the Testpoint with my oscilloscope and yes it gives 12V for about 250ms. These are my configurations I made to the sketch: // User defined settings #define MEGA 0 // Set this to 1 if you are using an Arduino Mega (default = 0) #define DEFAULTMODE ATMEGA // If running in non-interactive mod...

Re: Trouble programming a ATMEGA88P with Arduino Mega 2560

I tested the shield with 3 misfused atmega 88ps and I tested to write high and low, and then just low. All with the same result. I have before also tested to oszillate the misfused 88p with another 88p where i set the fuse to let it output its clock signal on pin 14 (checked with oscilloscope) but i...

Re: Trouble programming a ATMEGA88P with Arduino Mega 2560

Hi
I have now ordered an Arduino uno. I had not much time the last two weeks but ill try out this one.
The values seemed to vary each time I tried to read the fuses, but sometimes they stayed a few times.
I'll make a screenshot as soon as I come back home.

Trouble programming a ATMEGA88P with Arduino Mega 2560

Hello! I got my HV Rescue Shield 2.1 yesterday (Thank You :) ) and soldered it together. However I have a problem getting it to work. Like mentioned in the title I want top reset the fuses of a ATMEGA88P (the host board is a Arduino Mega 2560), but the Arduino Board keeps reading in some random Numb...
