Hi, I'm looking for a Sub PCB.
PM me if you've got a lonely one.

Hi WT,

To be complete, all you need to flash the C, is the onboard power supply (5V reg and caps), the oscillator circuitry (crystal and caps) and the reset circuitry (classical RC components), plus the connectors.

If your C board is complete, you just need to provide the digital power supply. That can be, as said, a simple 9V battery.
In this case, all you can test is the detection of the C with the JTAG interface and the good flashing control test.
With the LCD display , IR receiver and wake switch, you can test the main functions. For a complete test, you will also need the encoder.

The IR receiver is mandatory, as it is wire to a NMI input.

You can simulate the wake switch with a touch of a screwdriver.

Cheers,
Trung

Thanks Maousse for clarification.

I just complete the uC board only need to solder IR receiver to it.

Manu, Ceeve & Maousse just said it all
You can "emulate" the IR receiver (faking its presence) by piggybacking a 10K resistor on the IR connector bewteen the signal pin and the +5V.

Cheers

I finished the U-controller board and power supply. All of the power supply work as they should be. 5V on the u-controller board is working fine, led is turn on.

However, when I connect the program board and try the ponyprog2000 with steps from Cheff;
on Security and Configuration Bits when I hit read button
the program try to read and error occur
"Device missing or unknow device (-24)"

Am I missing something? How should I check what went wrong.

I use google to translate the ponyprog2000 file from French to English, so I can understand it. It is not perfect. May be I miss some points in there. Please help.

Connect your programmer board to your parallel port, but not to the target board (the C board)
Lauch pronyprog, your C settings (AVRmicro and ATmega64) should be recalled.
Click on the "mechanics wrench" icon, just on the right of the printer icon.
The setup dialog opens, check your settings wrt the pdf file, and click the "probe" button.
What is displayed ?

Hot news :
Two of the french diyers had the same problem (unknown device).
It happened that it was a bad db25 connector, at least for one of them, to be confirmed for the other...
Is yours the right one ?
It must be a MALE DB25 connector on the programmer, and a FEMALE one on the computer. Check if the pin one of the connector matches the pin one on the programmer pcb and on the computer...

I agree with Cheff, had the same issue with my initial tries...verify that you have good contact in the connection with the PC port,....hope your cable is not too long as well...and sometimes if you are using serial port this may not let you use parallell conection.
I had all these problems, but you know...if it does not work, revert to basics, it's easier to identify causes.

It's confirmed for the second guy.
Wrong DB25 connector.

FYI, on a PC, a female DB25 is the parallel port, a male DB25 is a serial RS-232 port, but this connector has been simplified to a male DB-9.

The programmer is designed to be directly plugged on the PC parallel port, no need to use a cable between the PC and le JTAG interface.

Cheers,
Trung
