Thanks for http://www.referencedesigner.com/ for the tutorials

• 24_bit_counter -> Show 4 MSB of a 24 bit counter using the internal 12Mhz FPGA clock Link
• Prescaler -> Taking the 12Mhz clock of the Icestick and reduce it's speed to turn on and off a LED. Link
• Multiple Prescalers -> Using the previuos example, reuse the same module one for each led to prescale 4 different periods. Link
• 4 bit counter -> An improved counter using the previous 22 bit prescaler Link
• 4 bit register -> Maintains the state of 4 register to turn lights on and off Link
• Initializer Link
