Help/Explanation needed

Hi all. I'm new to this forum and to PicBasicPro and need some help.

This is my code:
TRISA = 0
Main:
Pause 250
High PortA.0
Pause 250
High PortA.1
Pause 250
Low PortA.0
Puase 250
Low PortA.1
Goto Main
End

(Tried this as well: Symbol LED = PORTA.0, High LED AND PORTA.0 = 1)

My expectation is that PORTA.0 will go high, then PORTA.1 will go high while keeping pin 0 high. But this is not the case. When I make any pin high, the rest go low. Is this the correct bahaviour?

I underdstand PortA = 7 will cause pins 000111 to go high, but surely portA.x should not affect the state of the other pins? or am I wrong?

I'm using a PIC16F676 with PicKit 2 Programmer.

Thanks in advance

Welcome to the forum.

The PIC you are using has analog on PORTA. You will need to make it digital.
Add this near the top of your code

Code:

---

ANSEL=%00000000
CMCON=%00000111

---

And this thread will be some good reading
