why not make each persons code the correct 16 bit number for the doors that thay have access too. if a person has acces to all doors his code would be 65535. you could use some type of encryption sche ...

Hi Ritchie,
My understanding is that you would require a 16bit word to be stored for every user. You could manitain a 2-D array for this.

This will give you a table with ...

These are 2 separate problems.

i wrote an bootloader and he works fine. today I want to compile again and i get an ERROR

For the ORG error - do a search for INVALID ORG ra ...

Are you sure this is where your problem lies? It compiles fine for me. I don't know what you have declared your variables as, but I declred them as ints.

int grados, centenas, num1, decenas, unida ...

Aha! The problem only occurs when I use the debugger, as you implied Neutone. When I download the code and run the actual RS232 over hyperterminal it appears to work fine.

Try including these lines

setup_counters( RTCC_INTERNAL, RTCC_DIV_256 | RTCC_8_BIT);
setup_adc_ports( RA0_RA1_RA3_RA4_ANALOG );
setup_adc(ADC_CLOCK_INTERNAL);

ensure your are connected to the ...

Here is a condensed sample of the code I have been using. Although I am only reading one ADC channel, the problem remains.

NOTE: if either ISR is removed the problem goes away. So I'm thinking the ...

Hi Neutone,
I am just reposting this so that you know it is from me. I didn't realise I was posting as guest the last time.

Sorry, I do actually have a call in the ISR to 'cmd=getch();'.

I shou ...

Oscarlj,
Can we see more/all of your code as I cannot follow the relationships between your variables here.

One thing which looks suspect however are the follwoing 2 lines:

if(s)
c = s[i ...

I tried your suggestion Neutone - the problem is still present.

I have noticed that I have a second ISR (#int_rda) - when I comment this ISR out the A/D conversions work fine. Strange as I am not ...

I am developing code using a 16F877 chip which has an interrupt routine which interrupts every second and sets PIN_C0 high and then low. A short time after the interrupt routine is called it will rea ...

Hello everyone.
I need a simple code to set up for 4Mhz internal oscilator for 16f88 mcu

I guess it is no the same as it would be for any other PIC, eg:

#include <16F88.h>
#use delay(clo ...

Hi Neutone,
I haven't tested this code but it is just an idea. In theory it should work.

if(packet!=0){

for(i=7;!bit_test(packet, i);i--) ;
// i has found first errored bit

Is the data being read from the eeprom be the ascii code, or is it in hex..???

arun

It shouldn't really matter what form it is stored in the eeprom. Any format whether hex, char or decimal i ...

Hi Leonardo,
Before issuing an i2c_stop you need to issue a no-acknowledge with your last communication before the i2c_stop. For example after doing a series of i2c_reads (issuing an 'acknowledge' ea ...
