Awesome. I think that was it. This board has a 3.3V switching power supply running the micro. I also have a 4.7V zener on the power supply output because I have seen some pretty wicked spikes at...

I hit erase, and it says

Erasing...
Erase device complete

but then I fail a blank check

pic is running at 3.3V

using PBP 2.6C (I know..upgrade!) inside MPlab8.7

Hello,
I having a heck of a time reprogramming a board with a 12F615 on it. The first program will download and verify just fine. After that, there are errors in different program memory...

Thank you for the link. Looks like I've got some reading to do.

No I have not seen that before. from what I can see, and I didn't read it all, it looks like example code to make the chip play mp3s.

oh well, at least I can make piano tones at the moment. time...

Hello. Here is an update.

I bought the VS1103 breakout board from sparkfun. I hooked up power, ground, and the Midi Uart data going into the chip. and...nothing. then the project sat, and sat,...

I'm looking for a midi synth chip to add to my (picbasic) cap sensor piano project. Anybody have a favorite that is readily available? So far, I've found:
CS9236
Vs1103
And the
ATSAM2195
...

Thanks everybody. I was slowly realizing the same thing on my own, but it's nice to hear from you guys.

I'll look into the MCP1703, or other low Q LDOs

hmm... I'm nowhere near microamps, I'd love to be in the uA range. I'm powering the board at 12V, and using the pic's internal 5V shunt regulator. I've got a 510 ohm resistor between the power...

I verified that I'm am indeed running at 4MHz. and I set the nap period to 7, and the chip becomes unresponsive for long periods of time...
then I set the nap period back to 0 and commented out...

wierd..I AM loading 8 bits into those registers..I swear. it's just not coming through

I have this project at work (can't really post the complete code)where I'm using the ECCP on a 12HV615 to output a PWM signal that changes the duty cycle with a button press. I had the chip blazing...

no suggestions. OK. so that was a pretty long winded post. Sorry. but anyway, I'm moving away from the idea of hacking up my old keyboard and I'm thinking that I could spit out midi messages to a...

this project started about 2 years ago. I had a large piece of perf board, a super simple, relaxation oscillator, non-interupting, 1-channel cap sensing routine running on a 16F628A, and a 16 to 1...

yes! I got it working. Thanks for pointing me to the pic multi calc program, what a life saver. I used it for figuring out my interrupt timing, but I didn't see that it also did EUSART settings. ...

thank you so much for the insight. that got rid of the erratic readings. I was able to set a threshold, and not update the average during a button press, and also count the amount of time that the...

Hey DT,

I've used your averaging routine on some of my non-interrupting (start timer, pause for 50mS, stop timer), relaxation oscillator, cap sensors, and it's worked great. Now I've graduated...

OK. I'm missing something here. How do I make sure I have the latest PICKIT2 device file? will I be able to program the 16F1823 in MPLab, or just the stand alone program?

on Microchip's ...

so, this is a continuation of the thread started by ero, named 'Capacitive Touch Button by using ADC channel (the CVD system)' that I sort of hijacked. HankMcSpank helped me out a ton. Many thanks...

Hank, awesome. you -seriously-made my day. I'm picking up the 12F1822, and 16F1823s this afternooon, and I should be up and running in no time. will I have to modify my DT file like you did a...

Hank I'd love to see how you set it up. Thanks

Thanks everybody. I love this forum.
Looks like I will get a 12F1822 for my low pin count micro, and a 16F1823 for my higher pin count micro. I was kind of put off by the lack of examples here.

ero, Martin, or anybody

I've been trying to do this with a PIC16F819, with only mediocre results. My 819 has a 10 bit A2D, while I see that you are trying it with a 8 bit A2D, so theoretically,...

look into Darrel Taylor's 3 channel software PWM code - it's interrupt based. I'm not sure if it's ready to run on a 18F4550. Your main loop would look something like this:

FOR x = 0 to 255 STEP...
