一个纯硬件SPI的ISD17xx驱动,只用到了其中放音功能,录音、擦除功能没有使用,所以这些函数没有加上去,如果你要用加起来应该很简单的. 程序用M8做的实验,电路中有一个LED和一个按键,实际产品用的M64,编译器用的IAR-A pure hardware SPI, ISD17xx drive, of which only used playback functions, recording, erase function is not used, these functions do not add to, add up if you want to use should be very simple. Procedures to do experiments with the M8, the circuit There is a LED and a button, the actual products used in M64, the IAR Compiler Used
