FRDM-K22F:  Working with arrays

Question asked by brian cavanagh on Apr 6, 2018

Hi, I'm looking for an example of how to use arrays in my code. 

 

What I currently have is a CD4094 8-bit shift register connected to the FRDM-K22.

I'm using PTE0 as a clock, and PTE1 as my Data pin.

All the outputs of the shift register are tied to leds so I can confirm it works.

Below is a picture of the shift register if anyone's interested. 

 

This is more of a fun project for me.  I'm using KDS 3.2.0 and PE.

 

 

 

Below this statement is how it would be connected, IF, I was using an ATtiny 13.

 

Also included is the code for the ATtiny below that.  The syntax used to create the array I assume is different than in KDS.  My biggest problem is correctly writing the code PRIOR to "int main(void) {...", i.e. initializing the array,

followed by what to write within  "int main(void) {...}" in order to use the array.

 

I did try, however, I haven't been successful.

 

Thanks,

 

Brian
