Yes, you need a common ground connection between the two devices.

Thanks a lot for your help - I was just hoping I could mash the circuits together but looks like I will need to build a whole new c ...

Do you have a ground connection between the Gnd pin on the Memec
and the Vss pin (i.e., ground) on the PIC ?

No, do I need this, do I need to put a line between the ground of the PIC and the groun ...

Post your compiler version. It's a number such as 3.191, 3.249, 4.020,
etc. You can find it at the top of the .LST file, which is in your project
directory. Don't post any numbers that come a ...

Hi All,

I have some problem with some A/D code I have written. I have 1.2ish Volts applied to AN1/RA1 on my PIC18F2550. I did not use AN0/RA0 ( is this a problem )

Now all I get is various rando ...

Hi All,

I am compiling the serial/USB example and I have now managed to get it uploaded to the PIC and also my USB circuit is working as when I plug it into the USB port of my PC the PC installs a ...

Start with needing some decoupling on the Vdd-Vss connection close to the PIC. Something like 100uF, paralleled with 0.1uF.
The, you will need to comment out the lines in the source, dealing with US ...

Hi, the first thing i would do is change C3 to somthing more like a 470uf cap, see how you go then.

Have fun , Mark

470uF ? not 470nF ? Just a non-polarised capacitor?

Thanks

Hi All,

I built this small USB circuit for my PIC18F2455 - I have now been able to compile and upload the examples to the PIC. However nothing happens at all in windows, no drivers get installed, n ...

Hi All,

I am using a ART2003 programmer which is specifically targeted to the PIC18F2455 chips. If I use a simple C program then WINPIC800 will load up the program to the PIC fine, but as soon as I ...
