Random number -> Corresponding LED lit (n00besque content contained)

[Archangel]

We really need to see the entire code esp. the lookup tables.

It worked perfectly for me ....any reason you have not copied the code verbatim?

Re LED1 never lighting, what happens if you comment out the random aspect & simple make mybyte = 1 (where 1 is the LED you're not seeing lighting up etc)...this should light the suspect LED up all the time & proves both the wiring/LED at least.

Re the same LED lighting in succession, I'd approach this by getting some debug/hserout info of 'mybyte' onscreen....else you're grasping in the dark. (no pun intended!)

I did run another program to ensure all the LEDs are hooked up and working. They all work using the cut and pasted look up tables provided.

Hank, when you say it worked perfectly did you use the schematic I provided? The last time I chased a problem with these LEDs, it turned out to be the circuit not the code. If you look here http://www.picbasic.co.uk/forum/show...ght=wood+chuck you'll see what I mean.

Here are the look up tables.

lookup mybyte,[%000001, %000010, %000001, %000100, %000001, %010000, %000001, %100000, %000010, %000100, %000010, %010000, %000010, %100000, %000100, %010000, %000100, %100000, %010000, %100000], gpiostate
gpio= gpiostate
lookup mybyte,[%111110, %111100, %111010, %111010, %101110, %101110, %011110, %011110, %111001, %111001, %101101, %101101, %011101, %011101, %101011, %101011, %011011, %011011, %001111, %001111],tristate
trisio= tristate

I don't currently have the knowledge to display my number on screen but if the LED is lit by another program, proving it does work, then looking at a number will only tell me that the LEDs number never comes up.

I wonder if someone could explain the
"MyByte=(MyWord//6)+1" part? // = Remainder (Modulus)? It isn't clear to me what this is doing and how it is extracting the 6 variables.

I need to randomize 8 LEDs and would like to understand it better.

Thanks

If you do the math with a calculator you'll, in my opinion, never understand modulus. Use paper and pencil for some small numbers and you'll see how modulus works.

I believe to randomize 8 LEDs all you need to do is change the 6 to an 8. Like
Random myword
mybyte=(myword//8)

Depending on how you use mybyte depends on whether or not you need to +1 after myword//8.

I'm sure someone will chime in and say I've messed up but there you have it.
