there it is, add

lcd_init();

inside main, before the while(1)

I'm on my phone, so I don't have access to the lcd code, but I think that the lcd needs to be initiated, I think is lcd_init(), check in the lcd.h file

I don't know why, but I solved it changing the Master Address to 0x60, and the Slave answer at the address 0xB0. Really weird, probably because I'm using a invalid address for the slave or something l ...

The value of TEMPORARY is 0 when the program starts and is reset to 0 when you press ENTER.

So, you start your program and temporary=0

Press 3 ==> temporary = temporary*10 + key ==> ...

Sorry, I posted in a hurry and wasn't able to finish.

Let's say that the value you read from the keys is stored in a variable named KEY.
I'm assuming that you have a keypad with numbers 0-9 and at ...

so you need to get data from the keypad

You'll need a ENTER key to tell the program when you're done entering numbers
create a variable to hold the data and with each number pressed, do something ...

I'm using a PIC18f2550 as a master and a dsPIC30f3013 as a slave, and the interrupt in the slave never triggers.

I started 2 new projects leaving the code at its bare minimum.
The oscilloscope sho ...

Try pasting the code I posted inside the main. The delay should be clock=40M
The pic must start slow and in the code you must increase the speed. so, do it like this:

//put all your fuses here ...

the safest bet is using an OPAMP as voltage follower such as the classic lm741, or a lm324 (four 741 in one IC)

Could it be that the divide by 10 on peso adds many cpu cycles so there is a noticeable delay between the low and the next high. Removing the divide means the the high and low are very few CPU cycles ...

shouldn't the functions be outside of Main?

Hi, I'm running a dsPIC33FJ128GP802 with this code:

#include <33FJ128GP802.h>

#rom 0xF80006={0b1111111101111000} //FOSCSEL
#rom 0xF80008={0b1111111100011011} //FOS ...

an easy way to do it is to check the buttons every 10 ms, and activate the leds when the program detects the button presed twice in a row... something like:

int left_led;
do{
d ...

Hi everyone.

the 33FJ128GP802.h has definitions por all the pins from port B, C, D, F & G, but this pic only has ports A & B, so I can't use port A, and don't know how to add it.

the por ...

Thanks Mauro! that's exactly what I was looking for, the clock in the 33f is a real pain in the neck. Now, what I can't do, is configure the pre, post & clockdiv, the 33f assembler is waaay too mu ...
