I wrote all of the stuff from scratch. this time i did it. it works well.

i will tell something about App Inventor who wants to make projects over bluetooth modules. Keep in mind that App inventors ...

This the hc05 that I'm using. it has BC417 chip. I use voltage divider for logic l ...

Hello everyone,

I am on a project that should be interface over android bluetooth hardware.

I used PIC16F876A and HC05 bluetooth module.

I can receive single characters, there is no problem ...

compiler version 5.015
mcu/dsp : dsPIC33F

i want to know something about variables and calculations.

example:

float k;
int16 x, y, z;

x=12546;
y=15098;
z=x+y;

k=(float)z/2; ...

i found that. in the dspic33fj128gp802.h stack size is 31. but when i compile my program, in the statistic page the stack size is 128 and its %100 full.

so i do this after Fuses lines

#build (st ...

Ok, i add an 1M resistor across to the crystal, 15pF capacitors still there.

the dsPIC work fine.

but when i set any interrupt (TIMER2 RS232-recieve etc..) and when the interrupt is comes the d ...

if I use 1M resistor across the crystal, there are no need for the 15pF-22pF ceramic capacitor?

I don't know what am I do or what's happend but at now it works perfectly with these Fuses

#include <33FJ128GP802.h>

#device ICSP=1

#FUSES NOWDT //No Watch Dog Time ...

There is any information about that 1M Resistor across to the crystal. in my opinion thats not necessary because i used a while ago 18F4431 10Mhz crystal to get 40Mhz with PLL. i didn't need that resi ...

I just want to know the code wich do; 10Mhz external crystal to with PLL up to 80MHz to use at 40MIPS that dsPIC33FJ128GP802.

i tried many things, i lost my brain but i can not find any solutions. ...

I tried some things like that;

i changed the

#use delay(clock=80mhz, crystal=10mhz)

to

#use delay(clock=10mhz, crystal=10mhz)

the #FUSES HS, PR_PLL are the same

with this it works ...

#include <33FJ128GP802.h>

#FUSES NOWDT //No Watch Dog Timer
#FUSES NOWRTB //Boot block not write protected
#FUSES NOBSS //No boot seg ...

should i use a cooling system on it? my system will work only 10min per fly the quadcopter.

but my main question is how to configure the Fosc to 80Mhz to use the dspic with 40mips ?
i have 10mh ...

compiler version 5.015

I'm going to use this dsPIC33 on my quadcopter. I planned to do this with 18F4431 but it's really slow while calculating float variables.

so my question is about how to u ...

Hello,

don't tell me read the datasheet of the PIC18FXX31.
I read it. but there is no way to use on CCS C.

from the index i found these functions.
