Man Zhang · Journal of Xingtai Polytechnic College · 2013
This paper introduces the design of a guitar tuner which is easy for beginners.The design takes FPGA as the core,by picking up the strings sound signal with the pickup,then amplified and input AD7991 chip with analog to digital conversion.At last,communicate with FPGA through the I2C interface,to achieve the frequency regulation.
