I'm thinking for the sake of less components on-board, the extra ROM use won't be a huge concern. I will look into the USB bootloader, thank you all for the suggestions, this has been very helpful.

Hello,

I'm trying to get some input from the community, as there are a few ways to go about this. I'm building a PCB which will use a PIC micro. I haven't yet chosen which PIC, but it will likely b ...

compiler 4.033
pic18f14k22

I feel like this should be possible, but I've tried everything that makes sense to me and searched the manual up and down, there seems to be no simple solution.

I'm t ...

Perfect, thanks. Using your equation I figure 'mode' will need to be 210 in order to achieve as close to 38Khz as possible.

(32000000 / 4) / 1 / (210 + 1) = 37914.7

I'm trying to set up a pwm output of roughly 38Khz and I'm just a little confused about how to set up timer2.

In the data sheet, it says to set up and enable timer2 in order to start the PWM output ...

Oh great, I always thought this was determined by ASM rather than the PIC.

Thanks again.

How do I know how many cycles an instruction will take? In that link, you mentioned that BSF and BCF each take 1 cycle, but GOTO takes 2. Is there a resource or document that lists each instruction an ...

Thanks for the help. I'll look into using fast_io to save a couple cycles.

cheers.

Based on that I'm still missing many clock cycles.

.................... output_high(LED);
01E0: BCF F92.5
01E2: BSF F89.5
.................... output_low( ...

I don't think it takes 12 clock cycles to run a simple output_high instruction.

I'm running the 18f14k22 at 64Mhz. The problem is, my program is as simple as:

#include "18f14k22.h"

Check page 48 (pdf pg.60) in the CCS manual. It is possible to create a pointer to a constant. What is your compiler version?

I'm not sure if it will be any help, but I honestly don't know enough about USB c ...

can you check/ clear the buffer? What device are you using?

You can always use 1 PWM, connect all H-bridge inputs to transistors whose bases are controlled by 10 seperate 1/0 ports and the emitters are fed by the pwm output (amplified?), then write an algoryth ...

I back up all of my work daily. I'll definitely post my program as a 'working code' once I get a few commands done. Right now it's still a jarbled mess of test functions that were lazily thrown togeth ...
