Hi all,

I am using a PIC24F04KA200 with 4.104. I successfully generate a PWM with pulse width (duty cycle) and period as programmed. However this only works until a period of ~16.4ms. Faster than t ...

Reinstalled the compiler... Everything worked the way it is written in the listing of my original post. I guess something in Windows went to hell :(

Do I need a #use standard_io statement for the port I want to use? That's now the way I changed it. Going to go try it now...

Anybody? Bueller?

Plz, I really got to have this app working!

I'm hoping this is something silly, 'cause I'm stumped. I'm using 4.099, have the following test project:

#include <24F04KA200.h>

// Do some configuration
#fuses NOPROTECT, FRC, OSCIO, NO ...

Hi all,

I'm using the PIC24F04KA200 device and have the 4.099 compiler. setup_spi() broke during compile, which was odd - that had worked on other MCUs... Then I noticed that the header file for t ...

Yes, I did. Refer to http://www.faqs.org/faqs/ai-faq/genetic/part6/ for more details.

Breno,
Your're right, F88_CS does indeed need to be declared. It is a variable equivalent to a pin on the F88 chip, of your choice. When I pasted the code in, I removed some lines that were applicati ...

Hi all,
I'm trying to create a system that interfaces to a digitizing altimeter and displays altitude information. As is the norm, my altimeter uses Gray code (aka Gilham code) as the output. However ...

Ahh, I see now. Well that clears things up. Thanks for your help guys.

Of course not, I simply meant that the minimum the design would have needed is 200 kHz. It can go higher, but not lower, hence the full speed 400k I2C spec is the ticket. In any case, I got it on a br ...

Sorry, I didn't put the clock of the PIC... its 40 MHz, thus allowing for the afore-mentioned 10 MHz SPI. I would really like to have a sampling rate of 200 kHz with the I2C sensor I'm using, so its h ...

Hello all,
I am stuck having to use SPI and I2C on the same PIC18F458 device. Based on info from previous postings, I am using 10MHz SPI using the dedicated hardware lines, and will use I2C on some o ...

Yes, Doug's simulated resistor concept is exactly what I'm looking for. I will try to implement this in a 40 MHz PIC and external A/D, that should be fast enough. Thanks for all your help.

I'm actually looking to sink quite a few amps. The DC-DC needs to be walked over its range of 0-7A. I'm a bad analog guy :( If anyone has more details, I'd love to know!
