serial communication and lcd problem

[m7md007]

dears,


i am currently on a project that have a variable such that let us assume that the variable
conv=0b01011101

1- i want display the value of conv on the lcd
(so that to be in the lcd 01011101 )
i tried to write
lcd_putc(conv);

but it didn't work

how can i do that

2- my second problem that i want to send the value of variable conv serially to another pic
(so that to transmit the bits 01011101 serially to the other pic )


can any one help me
can any show me a simple ex how to do that?

good luck

while I'm waiting for the bird to be burned....

1) if you want to display the data in BINARY, search this forum, as someone wrote a small progrm to do that....

2) to send it to say another PIC or PC, either look at the examples int he examples folder or read the FAQ section of the onscreen help file( press F11 when project is open).

You should have what you need in less than 1/2 hours of reading....

... time to uncover the bird.

Dear temtronic i really appreciate your sarcasm.

But i am new to ccs c for pic.
If you can be more specific in your answer and show me how do it in a real beginner level and show me the steps
i will be grateful.

Thank you in advance.

You need to write a loop that rolls through the bits of the variable testing each bit and then sending the proper char.

You can use if() { } else {}
you can use the CCS bit_test() function
you can use ()? : ;

What you want is pretty easy... but like all the others might say, it would not be in your best interest for me to write the code for you as you wouldn't learn yourself for it.

We're happy to guide though.

p.s. you don't need to PM us to help, I was already looking at this thread. Cheers.

first of all
thank very much for your reply

your advise was on my mind but i thought that there is a dirct way to show the binary bits for the variable on the lcd

second what about sending the bits serially to another pic

good luck

thank u for your reply
i will try to write the code for print the binary printing in the lcd

i am programming a pic 16f877a in ccs pcwhd 4.057

for my project i take an input from the keypad and depending on the input i make simple calculation and the result saved in a 8 bit variable called conv

then i want to send the 8 bit variable serially to another pic that display conv in the lcd in the binary form

that is the brief summery of my project

Why are you using 2 pics?

Doesn't an 877 have enough pins to do the LCD and the other stuff?

the two pic's are connected to each other through an rf wireless module so this module take the data serially from one pic and trasmit it wireless and the rx module receive the data and gave it serially to the second pic

for that to happen i must first let the pic communicate with each other serially and then i will instal the rf module

in a brief word the two pic far from each other

[bkamen]

then for your cabled version, consider using MAX221 (or equivalent) RS232 level translators over your long cable...

and then remove them when going wireless.

Can you be more detailed?
I am still a beginner.
note: please be patient with me.

Thank you bkaman

I solved my problem.

I did the code to display the binary.

and for the serial I defined a char called it conv_a
