Problems with K8048

Hi… i’m using K8048 programmer and when i’m trying to write demo.hex on PIC16F84A an error pops up.

write error at: 0000 
wrote 280A 
Read: 3FFF

I took my power supply from my router (and it output’s 12V & 500 mA).
What should I do?! should I rebuild the serial cable?

Hi

I had the same problem and for me it was my USB->Serial adapter, i try’d it on my old labtop with build in Serial and it worked just fine

Greets 8)

3FFF -> Empty location

It’s looks like a hardware problem, there is no comminication between the software and the inserted PIC controller.
Don’t use an USB cable !

I’m already using serial cable… if i remember right, there was the same problem with PIC 8 too.

Try another power supply.
