I recently purchased a FRDM-KL05Z and am using Codewarrior 10.4 with Processor Expert to do my developing. I would like to develop a guitar tuner and am familiar with creating a Processor Expert project and adding/editing components. I have worked through the sample programs provided through Freescale and Codewarrior that involve the ADC and have had great success. Can anyone tell me what PE components I would need to receive an external analog signal (GPIO?), convert that signal to digital (ADC?), and if I need a clock input or is that already taken care of by the ADC?
Thanks in advance,
