Do not know what I'm doing wrong.

Post by foppa »

Do not know what I'm doing wrong.
probably a piece of cake but I do not see the error.
When I press the button, the LED will light up and it does in the simulation of flow code.
but in reality it is the opposite, the LED goes off when I press the button
've had to work but can not remember how.

Hi John,
On your control panel, right click on the LED and select External properties.
Check that Polarity is set to Active High and not Active Low.

Also on your hardware.
With LED:
Connect o/p of microcontroller to the current limiting resistor e.g 470 Ohms or whatever value you wish to use.
Connect other end of resistor to anode of LED.
Connect cathode of LED to 0V

With the switch:
Connect the switch between +5V and i/p pin.
Connect a pull-down resistor (E.g 4k7 to 10K) between i/p pin and 0V

What is your osc speed?
Any speed greater than 4MHz, its best to run with HS for osc selection rather than XT.
This is not what is casing the issue you posted about.

If your still stuck can you post a flowchart and a circuit diagram of your hardware please.

Realizing that it was badly connected on the pull-down resistors
after I read what you wrote.
Was linked 10K between I/O pin and 5V :oops:
But now I have connected it to the I/O pin and 0V
So now it works as it should.
Should build on my project.
Thanks for your help

John :D

Can you look at my file and tell me why output
AO, A1 AND A2 will not go to high.
this led is use 5v.
because it is not necessary to use resistor for them

Hi John,
What version of Flowcode V5 are you using?

Professional, Student/Home or free?
