Ok thanks alot. So i have 2 options of code to use
1 - the lookup table
or
2 - the bitshift function
is one better then the other or just personal preference? I will be using the i2c driver for my display and this RPM stuff is just the start of it. I now need to find out the best way to flash the last "on" LED in 11111000 if a variable has been set to 5 or if the variable has been set to 6 flash the last "on" LED in 11111100.
