This CL adds the driver support for the WoV module which inludes the following files: - wov.c - wov_chip.h - apm.c - apm_chip.h It also supports the console commad "wov" which can test different configuration and audio quality by entering different parameters. The detail description of WoV console command is listed below: ------------------------------------------------------------------------ [Note]: Before changing any of settings, please make sure the operation mode is on the "OFF" state. (ie. run the command wov cfgmod off first) . > wov init Initialize WoV interface, including pin mux and interrupt registration etc. > wov mute <enable / disable > mute enable / disable. > wov cfgsrc <mono | stereo | left | right> set audio source, ex: wov cfgsrc left, means audio source from left MIC. > wov cfgbis <16|18|20|24> set audio resolution, ex: wov cfgbit 16 means audio resolution are 16bits. > wov cfgsfs <8000|12000|16000|24000|32000|48000> set audio sampling frequency rate, ex: wov cfgsfs 48000 means audio sampling rate are 48Khz. > wov cfgbck <32fs|48fs|64fs|128fs|256fs> set I2S bit clock rate, ex: wov cfgsfs 48000 and wov cfgbck 32fs means audio sampling rate are 1536Khz (32*48000). > wov cfgfmt <i2s|right|left|pcma|pcmb|tdm> set I2S but format, ex: wov cfgfmt right means audio I2S format are Right-Justify. > wov cfgmod <off|vad|ram|i2s|rami2s> set audio operation mode ,ex: wov cfgmod i2s means audio output via I2S bus. > wov cfgtdm <0~496 0~496 0~3> set TDM time slot, the first values is left channel delay counter, the second is right channel, and the 3rd is startup counting condition. (chosen LRCK raising or falling edge) . [Note: this command is just working on cfgmod equal to tdm] > wov cfgget retrieve above settings. > wov vadsens (currently not support, reserve for next version) > wov gain (0~31) set audio data gain value, ex: wov gain 10 means setting audio digital gain are 10dB. > wov cfgdck <1.0 | 2.4 | 3.0 > set digital MIC PDM clock rate. ex: wov cfgdck 2.4 means PDM clock are 2.4Mhz. ----------------------------------------------------------------------- This CL also adds the chip ID (0x24) for npcx7m7w. So the console command "version" can show the chip is npcx7m7w. BRANCH=none BUG=none TEST=No build errors for make buildall. TEST="BOARD=npcx7_evb make"; Flash the image on EVB; Test WoV function with console commands described above.
