schematic and codes...
Hi!
Just a begginer to pic programming, I have a pic16F628A and I'm trying to find a code & schematic for this mcu to use the internal clock and recieve data from hyperterminal that will lit Led1,Led2 and Led3. Hope you can help and thanks in advance....
regards,
mbox

Welcome to the forum !Originally Posted by mbox
Here is the deal, offered to all newbies. Write some code and we will help you make it work. Some here may do handovers, most do not, but most are willing to share their experience and knowledge. Why no handouts, because you learn very little from them, whereas if you struggle, you learn, and before long you are helping others. So that said let's get busy with some code.<br> So for starters do this, write a program to turn on those LEDs either by changing a port status or just make a loop to flash them in sequence, it doesn't have to be pretty, or even work, but it should show you made an effort to.

hi!
thanks for the reply.. I have this simple code that will lit the LED1,LED2 and LED3...using Pic16F682A. But I Want to control them to hyperterminal. Can you show me how to enable the RX on RB1?
[codes]
CMCON = 7 ' PortA = digital I/O
VRCON = 0 ' A/D Voltage reference disabled
TRISB = %11110000
begin:
high PortB.0
pause 100
low PortB.0
pause 100
high PortB.1
pause 100
low PortB.1
pause 100
high PortB.2
pause 100
low PortB.2
pause 100
goto begin

You cannot connect pic directly to the PC Rs232 port! You will need a maxim 232 as an interface.
Read the manual where you will find some example of Tx and Rx.
When You have setup your hardware, than remember you will send bytes via RS232 so your pic will need to decode the bytes sent via hyperterminal and act upon it. For instance I can set all 8 ports B to ON sending via RS232 "255" or set them all to OFF sending a "0".
Hope it will help you

Correct only if you are using the hardware serial from the PIC.
If you plan to use SERIN or SERIN2 then all you have to do is use inverted mode.
It is all in the manual

That's a start . . . .
now add a byte variable and a word variable, give them names meaningful to you, like LED1 or OUTPUTLED1 or MBOXVAR1, right now they will just be there, not doing anything, and compile to check for errors.
edit: Set your port latch before the Tris register, that way when the tris turns the port to outputs, they will be set at the desired state, next we will work on config statements.

Good morning!!!
This is my update code, adding 2 variables, when complied it says 85 words used.
[codes]
CMCON = 7 ' PortA = digital I/O
VRCON = 0 ' A/D Voltage reference disabled
TRISB = %11110000
PortB = %00000000 ' Turn pins to low state
Led1 var byte ' Led1 as a byte(8 bits) variable
myvar var word ' myvar as a word(16 bits) variable
begin:
high PortB.0
pause 100
low PortB.0
pause 100
high PortB.1
pause 100
low PortB.1
pause 100
high PortB.2
pause 100
low PortB.2
pause 100
goto begin

thanks for the guidance,
