AndyRate

An AVR rate calculator

Enter the target AVR crystal frequency and the desired output time period/frequency and the show a table of valid timer settings for each prescale value along with the actual timer output and error. The values shown are

• OVF8 - 8 bit timer overflow reload value
• CMP8 - 8 bit timer compare value
• OVF16 - 16 bit timer overflow reload value
• CMP16 - 16 bit timer compare value

Output values have been tested against the gold standard, Jack Tidwell's AvrCalc
