Here is a link to where I bought these crystals. [url=https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&storeId=10001&catalogId=10001&productId=324267]Jameco They d ...

Thanks for your reply, but I'm not sure that I understand you. You are giving the formula for capacitors in series; I don't have any in series. I am just running each leg of the crystal to ground thro ...

I've heard similar things from other people about crystals being flaky. Still, I have trouble blaming the crystal alone. Back when I was just learing electronics, when something wouldn't work, I would ...

This is slightly off topic, being mostly about crystals, but I know that a lot of you guys have extensive experience and I'm hoping you can help me.

I am running an 18F2455 using a 20MHZ crystal wi ...

Just playing around, I have had good luck with nothing more than a single pull-up resistor. First, tie the pin to power though a high value resistor (around 1M). Then just drive then pin low and time ...

I am also missing the file. To get the examples working, I modified the inf file provided by microchip with their CDC code. All that needs to be changed is the PID & VID so it matches what is comp ...

CCS just recently added the CDC examples and drivers, maybe a month or so ago. Update to the latest version and it'll be in the same place you found ex_usb_hid.

For a virtual com port you want a Communication Device Class (CDC). CCS has a driver, usb_cdc.h, and a couple examples, ex_usb_serial.c and ex_usb_serial2.c.

This is different for each device.

From the help file:
A list of all valid options has been put at the top of each devices .h file in a comment for reference. The PCW device edit utility can modi ...

Alright, I emailed them.

I changed the XINST fuse to NOXINST and now everything works perfectly. I would still be interested in why this is though, and why CCS makes XINST the default for a new project if it breaks eveything. ...

Can someone please explain this error message to me?

The Extended CPU Mode configuration bit is enabled, but the program that was loaded was not built using extended CPU instructions.

Whenever I ...

When I move #use delay before the #fuses then the RS-232 only receives garbage (a mix of 0x00 and 0x80). When I then add setup_oscillator things return to working just like before I made any changes. ...

Thanks for your input. I've read before not to waste time in interrupts, but this program was just a quick hack to try and demonstrate my problem with. It also seems that the interrupt never gets call ...

I am working on my first 18F project, and it's giving me a lot of trouble. I am running into several problems, and I'm not sure if they are related or not. When I program the PIC, delay_ms() doesn't s ...
