...hmm I'm quite new in this area and I have a problem with a pic programmer that I got from the link given below .
**broken link removed**
and I'm using a pic16f84-04 as the schematic suggests. To program the pic I've used the IC prog from "http://www.ic-prog.com/"
And my problem is when ever I try to burn my hex code in to the pic i get this error. Verify failed at address 0000h !
i'm kind of skeptical to the programmer as it is so simple...maybe it doesnt work..?? I dont know could anyone help me..
by the way i'm using winxp,amd 2000xp+
Thanks mate the page was swedish but luckily I'm a swed so that was easily sorted... I tried the Picup programmer same thing it failed writing to the pic.
Could anyone perhaps suggest a very simple pic programmer with as few wires and componets as possible..that of course works...for pic16f84
place it in the same cataloge as ic-prog.exe and run ic-prog.
goto settings->options->Misc and check the box where it says "enable NT/200/xp Driver"
click ok and the program will restart and install the driver.
...already done..that...if i try without the cable in the serial port I get a different message "chip is copyprotected"....I'm trying with a different pic programmer...also from JMD hopefully this one does the job. if any one have a good pic schematic...could you plz posted here.
And by the way I can read the chip sucessfully...hmm i dont know if that says something.
I got to say that in all the time I've been programming pics, I've not had a problem.
I've used the JDM design with IC-Prog, no problem there.
I suggest you check that the mclr pin is raised to around 13v when in program mode, if it isnt then the pic aint gonna be programmed and you will get verify errors. Also check that Ic-prog is set to verify after programming..........
pin 4 is the mclr pin, it hould have around 12-13v on it wrt to pin 5 (gnd) in program mode........the 12-13v is derived from the com port of your pc, look at the circuit, all will be revealed
yes I got the JDM 2 programmer to work and I burned the pic with ic-prog......
Now that I'm at it...is there a way connecting the servos to the rs232 ...i.e getting the power from the seriall port...cause that would be smother..right? But as I understood so far...the seriall port can oscillate..up and down in voltage...thus I need to have a fix 5v from it...how do I do that?
this is the controller I built (not my design though)...
The ps2 port and game ports are a nice source of 5v according to one of the specifications they can take 250ma each, however you should check on the hardware you use, like the parport current, there are about 5 differn't current levels.
