Re: how to extract audio volume level meter from audio stream ( PC(host) to Xmos device) ?
Hi infiniteimprobability, you mean, if sent calculated mutliplier by host (default ), samplesIn_1[ ] will be saved input channel audio volume (actual sample ) value, if sent decibel volume value by host, then samplesIn_1[ ] will be saved input channel audio decibel volume value is it right? thanks

one more thing, what means? the following code, thanks! if (timeafter(t_now, t_trig)){ unsigned mac_h, mac_l; {mac_h, mac_l} = lmul(left_vu, MUL_PWR_100_DIV_2P32, 0, 0); left_vu = mac_h; {mac_h, mac_l} = lmul(right_vu, MUL_PWR_100_DIV_2P32, 0, 0); right_vu = mac_h; t_trig = t_now + (DECAY_TIME_UNIT_...

Re: how to extract audio volume level meter from audio stream ( PC(host) to Xmos device) ?
Thanks for you information, mon2
int left = (int)samples_out[0];
int right = (int)samples_out[1];
you mean that samples_out[0] and samples_out[1] are left and right audio volume value. Is it right ?

Re: How to read/write flash in endpoint0( )
What ports/pins is your flash connected to? If your USB endpoint is running on a core on tile 1, then calling fl_connect(ports) will try to connect to the flash device using ports on tile 1. Be aware that (for example) XS1_PORT_1E names a port within a tile, but on tile[0]: XS1_PORT_1E and on tile[...

Re: which library or module should be included for read mac or serial number from OTP
hi, lib_otpinfo is the current library to use (eg. for storing ethernet MAC addresses). What compiler error do you get? It may or may not be related to this but we would need to see the details to help further. Thanks, infiniteimprobability, I'd downloaded lib_otpinfo library, I can compile success...
