Hello. I recently bought a GQ-4X programmer. I'm trying to program an atmega88 20PU. First off all, I did not found it in the library, only "atmega88*isp" and "atmega88V*isp". I did all the pin connections and the power on at the chip and got nothing. I know I have to use avr isp conection. So, the only thing a need to do is conect the pins (miso, mosi etc) and power on the target right ? This chip is not new and has been already programmed before. Any help will be appreciated. Sorry my english. I'm doing the best to make you understand.
Regards.

Ok. I'll build a circuit. Thank you for helping me.

The GQ-4X is supporting standard ISP programming.
If your chip is not in circuit, try to built up a simple circuit, include Vcc, GND, clock crystal etc.
If it still does not detect the chip, then the chip may be ISP disabled. Then you need to find a parallel programmer to enable it.

Thank you for replying this. I don't know if my chip is isp enable and I even don't know how to do this . The chip is not new. I just have connected the pins (miso, mosi, vcc, ground and reset) and tried to program. If get a new chip it will be more easy to do ? I have the configuration off the fuse bits to use with ponyprog, but a bought this GQ-4X programmer thinking it would be much more easier to do this.

Can you confrim your chip is ISP enabled?
Do you know if your chip set to use internal clock source.

Thank you for your attention. Can you give e the right configuration ? I'm using the latest version.Regards

The chip must be ISP enabled in fuse setting.

Also, the chip clock need to be set to internal. Otherwise you need a external cyrstal connedted to chip.
