is this also possible if i use Timer0?
i ask this, because if it is possible, i can use the programm in the flowcode examples (digital clock)

isnt it possible to let the pic sleep for a specific time?
something like this :
sleep(3600); //sleep 3600 seconds

Hi! I want to do the following: i want to check a device if an error occured or not... this should last for about 20minutes... when the 20 minutes are over the pic18F1320 should be set into sleep mode this sleep mode should last for 6hours then the pic should wake up and check again the device I don...

Hi all! I have a very special problem: i try to receive two characters with my rs232 component. First i try to check if the first incoming character is an 'a' or 'b' or 'c'. If it is one of the following characters, i try to check the second character if it is an 'a' or 'b' ... or 'o'. At the moment...

I have a special problem: in my first programm, i try the following: i try to send one characters (a) via rs232 (i use the rs232 marco) now i try to receive this characters, and if it has been received correctly, i want to flash a led this programm works fine now to my 2nd programm: when i try to se...

i changed now the oszillator frequenzy to 4MHz i use the internal oscilator, (output on RA6 and RA7) when i measure the frequenzy on these outputs, i measure a frequenzy of 313Hz... how is this possible? What is my mistake? I also added some pics, and my programme codes this is the frequenzy on RA7,...

i use the internal oscilator from the pic (19Mhz) i send one character via rs232 ( 'a' ) to a max232 and then to the hyperterminal of a pc i watch the outputs/inputs with an osciloscope (one scope at the tx output of the pic one scope at the max232 output) the programm works fine, also the character...

My problem is:
i set the baud rate in the rs232 component properties to 9600
when i compile the flowcodefile in the c-file stands:

#define FC_RS232_SPBRG_VAL 127

and if i check my baudrate via a scope then i have 16 baud...
what did i do wrong?

regards, andi

Hi all! Here is my problem: http://img511.imageshack.us/img511/8315/unbenanntuu9.jpg as you can see in the picture, i first set the variable "test=0" Then i check if an interruptflag is enabled (IRVST) If the interruptflag is enabled, i whould like to set "test" to 1 i tryed this...

juhuuu
now it works!

very big thanks!!!

for what do this numbers or directives stands for in the flowcode assembly file?
they are listed at the bottom of the file

with my assembler programm, i whould use the LVD (Low Voltage Detect) Funktion in MPLAB, it works, but when i try to use the same code in flowcode it does not work... here is my assembler code i try to use (this code works in MPLAP): //with these lines, i initialise the LVD trip point MOVLW 0x1B ; E...

hi, i tryed to implement an assembly code in my flowcode programm, but just "movlw" is working
if i try "movwf", "andwf" or "btfss" flowcode creates an error...
What do i do wrong?
(i use flowcode student version)

Ron is correct - you can add any C code you like to the "student/home" version. yes, i know that... but i decided to use flowcode cause of the existing implementation of RS232, cause i am not as good as other people in programming... can you give us then maybe a c-code from the RS232 plea...

Hi,I have a problem with ADC! Here is a picture from my flowchart http://img184.imageshack.us/img184/5386/picflowcodema2.png I devined Variable ADC_Value as Byte and Input is on A0 After sample (Makro=Sample ADC), i store the high-byte and return ADC_Value (Makro= Read as Byte) Then i check if ADC_V...

I have exactly the same problem

Hello Andi As long as the radio connection is working correctly then you do not need a physical connection. It is possible to pass variables by using the RS232. Eg send an instruction byte and then a data byte. The receiver would read instruction byte and then know what to do with the data byte. th...

hi all! To make clear my problem, i will try to describe my current project: I have 2 electronic devices which each is controlled by a pic. The first electronic circuit sends transmitts data via rs232 to a radio module. This modul sends the data to a 2nd radio module which receives the incoming data...
