Hi All,

I am looking for a simple programmer for AT89C55WD so I can build it.
I searched the internet but couldn't reach any valuable information. there is only one programmer at microchip website which is really expensive to me.
I also found a parallel programmer on internet but my PC doesn't support this interface anymore.
any suggestions ?

I'd agree with pickit2, the MiniPro is a good way to go.

Then you can use it on any other future project that comes along.

Why ?
It is cheaper to buy the MiniPro TL866cs and upgrade it to TL866A
plus you get all the adapters thrown in.

Whats the difference between TL886cs and TL866A, seem the same on aliexpress.com?

The only supported device I could finf did not include any of the 18FxxKxx series, did I miss something?

the TL866A has a icsp port TL866CS does not, but is upgradeable to a TL866A if wanted to do
some extra work to change firmware and adding a icsp connector.

The 18FxxJxx and 18xxKxx are programed the same way. the K devices are just newer.
But then you do have a Pic Programmer, don't you. if your using Pic devices other than just the one off.

For a list of devices is here. Note: there maybe a newer list of devices. wink or add your own devices, if you know where to look.

I guess that true in principle (modified SPI) it doesn't seem to be true in detail. In their infinite wisdom, Microchip have issued separate programming specs for the J and K series.

I have bought a Pickit3 specifically because it claims to support 18F26K42. If I could find a PK2DeviceFile.dat with 18F26K42 (although I did find for 18F26K22) I'd stick with my trusty Pickit2.

just asking, why are you using a 89c55

also, this one seems simple enough to build (this should work with a serial <-> usb converter)
