The compiler really has nothing to do with learning about a UART. You need to start with the datasheet and look for information on the basic underlying process, which is serial to parallel conversion on receiving, and parallel to serial conversion on transmit. Wikipedia is getting better and better at providing useful information and links.hello.,
i need tutorial for Serial UART using interrupt and C18 Compiler.
please provide me link to understand this..
...
i tried but didnt get suitable tutorial..
thats why i posted here...
As long as your chip is supported by your proteus version. You can do simulation. You can also cover a lot of debugging using the MPLAB software simulator. The C18 compiler is kind of outdated. It is better to use the XC8 compiler. If you will be using a free version anyway. To me it looks like you want to do a lot without accepting a to have a learning curve. It is better to start simple like not using interrupt in the beginning.it was helpful...but the its application is not clear that where we use this in real time applications.
for transmit and receiving data ,we have to write code separately for tranmitter and receiver..???
is it possible to see simulation on proteus for this , after writing code.?
You may not be ready for this tip, but you should know and understand the operation of a FIFO (First In First Out) buffer. For a serial UART they are often implemented in the form of a circular buffer.Writing code for UART is straight forward. Learn to do this yourself. Don't rely on someone else's code to do this. Read the manual.
Transmitter code:
wait until transmitter buffer is empty
send data
Receiver code:
wait until data is received
read data
#include <P18F458.h>
void SerTx(unsigned char);
void main(void)
{
TXSTA=0x20;
SPBRG=15;
TXSTAbits.TXEN=1;
RCSTAbits.SPEN=1;
while(1)
{
SerTx('Y');
SerTx('E');
SerTx('S');
}
}
void SerTx(unsigned char c)
{
while(PIR1bits.TXIF==0);
TXREG=c;
}
TXSTAbits.TXEN=1;
RCSTAbits.SPEN=1;
Rich (BB code):and also tell me how much important to config PIC.??
Because if you do not set the configuration words correct(according to your hardware config) it will not work. I have not been much active in this forum the past 10 days. So I just wonder. Have you done some simple "hello world" programming like turning a port connected to a LED on, and then get the LED to blink
I'm sorry I linked a bad webpage. This one looks promising:just use TX and SPEN,is it possible that this code will work to transmit and receive.
