Thanks. Is there a way to tell if the request was made successfully? I think I seen a snoopy program on one of the forum posts.

Been looking over some articles about USB 2.0 and found that a host will supply 500mA of current to connected devices. It also says that this current may be requested by a "high-power" devi ...

How can I configure the WPFP besides just using WPFP or NOWPFP? I only want to write protect the beginning blocks of flash. I am using the following code to allocate a flash location for reading and ...

Haha, you know when I was trying to get a program to post for you I was trying that out. I was using the ex_usb_serial.c file itself and the device used in that example must have less RAM. It worked ...

Here you go. Based on the ex_usb_serial.c code.

#include <18F26J50.h>

#device adc=10

Seriously, isn't there any documentation around with instructions on how to configure the USB? Or does CCS just expect you to use their default configurations?

I need a 1024 array of 16-bit variables in my USB application with the PIC18F26J50. I am getting the "Not enough RAM for all variables" compile error. I tried modifying the PIC18F_usb.c fil ...

I got a chance to go back to a Windows 2000 32-bit computer and everything seems to be working fine on there if I use the low-speed configuration. There must be something wrong with the Windows 7 64- ...

Yes, I seen someone mention the speed issue in another post. I figure I'd give it a shot since it was listed as an option in table 2-5. Wink

Windows did seem to at least kind of recognize it thou ...

Another look and the only difference between the high and low speed setting I listed above is that Windows device manager actually changed the name from SERIAL DEMO to "USB to UART" in low s ...

Just put some code together to use USB on the PIC18F26J50. It is basically just the ex_usb_serial2.c example code included with PCWH, but without the debug code and eeprom. I get a connection with m ...

Just got a new ICD-U64 and all works good. For some reason the whole 3V-5V and 3V only thing is just a little confusing. Have no time to wait for a hardware Rev update. Unless it can be done myself ...

Just tried to hook up the ICD-U40 up to a PIC18F26J40. Opened up CCSLOAD and found my part in the list and it failed to detect my part. I then disconnected the part and ran diags. VPP sits at 4V. ...

Sounds like you are going to have to do a customized ISR for the RS232 that checks the CCP1 interrupt flag and then calls a math function from inside that ISR.

You might be able to check the CCP1 i ...

did you setup the ADC?

setup_adc_ports();
