I wish I could help, but I never did get the new "sleep_ulpwu()" function to work on my chip. I used the manual coding that I showed earlier in this thread and it works fine. Perhaps CCS h ...

It seems the forum moderator thought I was spamming, but I really do have a Pyxos EVK kit that is just sitting in my garage. Certainly someone here can put it to good use. My offer still stands. Yo ...

I have an offer.

I was lucky enough to be selected as a beta tester for the Pyxos networking chips. I received their Pyxos FT EVK evaluation kit ($350) and helped them debug their tech manual, et ...

Thanks Ttelmah,

That's a relief since I already had 50 boards made using the TX pin to drive a fet.

I know it was probably posted before, but I seem to have difficulties getting the search engin ...

PIC18F1320.
PCWHD version 4.071.

I am using the hardware uart for serial receive, but I am not doing any transmitting. I use an interrupt (INT_RDA) to capture the incoming serial, so I have to st ...

Wow! That's quite a few bugs! Thanks! We will report it to CCS. I guess I'll stick to my manual coding for now. I was hoping the new compiler would work for me because I was running into difficu ...

I have a problem with the new sleep_ulpwu command.
Compiler version=PCWHD 4.071

I wrote the following code before getting an upgraded compiler that had the sleep_ulpwu command:

#include <12F ...

So now I can see that:

sleep_ulpwu(10);

is exactly the same as:

output_high(PIN_A1);
delay_us(10); // charge cap for 10us
code to make A1 an input, enable the ULPWU bit, and enable the int ...

Thanks all.

I didn't know I could access the latest manual, and that .LST file will be great for double checking my register assignments.

I'll give it another shot with this new info.

Can someone provide me with some insight as to what the Sleep_ulpwu() does differently than sleep()?

I ask this because my complier version is 3.249 and doesn't have the function. I spent several ...

Additional research for those interested in low power consumption.

There have been many posts from people asking how to make a PIC wake up from sleep. Most answers usually involve the use of a wat ...

Way overkill. I'm sure there is a $0.50 part out there somewhere.

I remember seeing an article about pulsing an IR led at 40kHz and then measuring time to reflection using a common IR detector tha ...

Does anyone here know what the latest technology is for hand motion detectors? Need ultra-low current consumption for battery powered unit. Similar to the automatic paper towel dispensers showing up ...

ding! Light just turned on. I forgot about that.

In the mean time I've been reading over a tutorial for assembly. I'm sure it will benifit me in the end for quick bit manipulations.

Thanks, ...

agreed. When I was talking about PBP it was with regard to the ability to have a low phase variation between captured edges. For some reason, polling the pin would give a horrible result.
