The PCA9674/74A is a drop-in upgrade for the PCF8574/74A providing higher Fast-modePlus I2C-bus speeds (1 MHz versus 400 kHz) so that the output can s...
单片机音乐中音调和节拍的确定方法:调号-音乐上指用以确定乐曲主音高度的符号。很明显一个八度就有12个半音。A、B、C、D、E、F、G。经过声学家的研究,全世界都用这些字母来表示固定的音高。比如,A这个音,标准的音高为每秒钟振动440周。 升C调:1=#C,也就是降D调:1=BD;277(频率)升D调...
