Flash Memory Program ming Specification. This document includes the programming specifications for the following devices:. The low-voltage ICSP method is slightly different than the high-voltage method and these differences are noted where applicable. Both supplies should have a minimum resolution of 0.

The first issue is with Timer2 - I have the system set to use an internal oscillator of 8mhz which I have verified - both with my scope as well as looking at OSCCON bits which indicate it is set to internal 8mhz.
What I am seeing is a hz interrupt with the above settings which indicates it is using the 8mhz direct into the timer I have the ISR toggling a led and it is toggling every 5ms. The second issue I have is with the AD converter - I have supposedly set it to use the internal reference at 1x which would be 1.
Below is a relatively simple version of my code that gives the results I have indicated. Any ideas what I am missing?? The 18F14K22 is also supported by the PicKit2 programmer. With the 16F, the timing was correct. Ttelmah Joined: 11 Mar Posts: Posted: Mon Nov 29, am.
How do you verify 8MHz with your scope?. Everything you have said, implies a system clocking at 32MHz. Best Wishes. Ah, that appears to be it - I had configured the int. On the output from CLKOUT, I had missed the part pg19 that indicates "the frequency at the pin is the frequency of the internal oscillator divided by 4". I did find a misprint in the data sheet for any others using this processor - pg , register ADCON1, bit should read "Negative Voltage Full speed ahead - back to getting this working to keep the hummingbird feeders from freezing during our cold snaps here - yeah, a hand warmer and bubble wrap works, but this is MUCH more fun!

This new family of devices offer all of the advantages of the well recognized PIC18F High Performance MCUs; 8-bit, C compiler optimized architecture and an industry leading peripheral set now available in a low pin-count option. These devices also feature the SR Latch mode which supports capacitive sensing applications. The addition of nanoWatt XLP technology make these devices ideally suited for battery powered applications or designs where power consumption is constrained. Finding the right compiler to support your device is simple:. Using an intuitive interface, it enables and configures a rich set of peripherals and functions specific to your application. MCC is AVR is expected soon!
