Digital audio experiment test engineering, the program demonstrated through the I2C bus pair TLV320AIC23 chip control, various audio loop, multiple sampling frequency, DMA audio acquisition and output, etc The test. There are detailed instructions in the program. TLV320AIC23 control HDL module Freedev_aic23 7 The register provides read and write two ports connected to the digital audio chip's AD and DA channels, each time Read and write a 32-bit wide data, which is the sampling value of 16 left channels and 16 right channels. every The subdata is the result of a sampling. If the sample rate is 48K, then each data interval is 1/48000. On this project, we can output our special processing data, such as the sine wave data, as well Can output (LOUT) sine wave signal.
