Yes, expected the inaccuracy. As our process is finished in ~10 hours this inaccuracy is no issue.

We are seeing with this code irregular values in the first line and no issues in the second line....

Those fuses let the 2550 run at 48 MHz, we coded a sample program and measured again with our oscilloscope


DebugLoop:
TOGGLE PORTC.1
PAUSE 100
GOTO DebugLoop

Which showed a ~40 ms pulse on...

I chickened out, if I use this construct:


T1CON.0 = 0 ; Turn OFF Timer1

Hi Darrel,

my fears came truth. I've inherited the codebase and suspected that those parts need updates as I visited your page and saw that updates were released after 2003 :rolleyes: BTW: The...

Hi Darrel, thanks for your fast reply. Thanks for your libs!

See the attached ZIP for the code

The PIC is a 18F2423 Device ID Revision = 00000007

No, it really definitly is running on 20 Mhz,

Fuse PLLDIV_5_1L provides internal 4MHz which is used to to drive the 96Mhz internal PLL which gets divided to 48Mhz for USB via _CPUDIV_OSC1_PLL2_1L...

Hi,

when we measure a voltage divider and have activated the timer for ELAPSED.PBP from Darrel Taylor, every 40th measurement or so is way off. When we never call start_timer from that file our...

We have
