I am looking for some help I have just started to use this software but the penny has still to drop. Any way what I am looking for is to find code examples to use but cannot find any. I want to be able to turn a number of outputs on and off by using a push to make switchs, each time I press the switch I want the led to change state but can not seem to find any examples to assist me. I can get the led to light when Ihold the switch down but it goes out when it is released. Could anyone assist me with a example peice of code.

Hi steve22, you ought to have a list of demo programs in your instalation of flowcode but you need to go through them one at a time
as they are listed with a number. I have attached one of these demo files here, this one uses a switch to cycle through a number of leds
, these leds represent an increasing count so you can see the progression each time the switch is pressed.

Hi
I was going through these samples but none really addressed what I was trying to get. As I dont have much of a grasp of it just yet .In affect what I was trying to do was understand the workings of the 4013 d type flip flop and to create a working peice of code. .

I am not trying to go as far as the code listed. I was trying to get to grips with what was happing behind the program, this is why I was lookig for a simple coding example of press button light lights press button again light goes out.

Sounds like a college assignment...
There are lots of videos, example files and tutorials on our website - please look there for some ideas.

After getting output though port B through a screw terminal and connecting wires from the terminal to a keyboard encoder I was able to see letters from the encoder in notepad. When I tried to compile my multi-click test program it failed even though it worked in the simulation. I received the following errors:
File name: Z:\Flowcodesaves\PICstickfinals\PICmulti-click_axisEPROMs1s2test.c
Generated by: Flowcode v3.2.2.40
Launching the compiler...

Any help would be greatly appreciated.

Hi Jeff,
What chip are you using. Also please could you post up your FCF file and I will have a look at the problem for you.

Sorry I neglected to attach the FCF and failed to metion I'm using a PIC 16F877A I should know better.
Thanks,

Hello Jeff,
The problem was caused because you have an unused RS232 component in your program.
To view the component use the View -> Attached components menu.
You can then use the RS232 drop down menu to delete the component from your program.
Your program should then compile correctly.

I removed the RS232 and was able to compile successfully, only to find that my program which accepted input for my multi-click switches in simulation doesn't do so after burning to the PIC. I broke my program into steps to find the segment causing the issue. I successfully tested the hardware inputs right before burning the section in question with a simple input/output program to confirm it isn't the problem. Attached is the section in question. Any ideas?
Thanks,
Jeff
