fht_adc.pde
guest openmusiclabs.com 9.5.12
example sketch for testing the fht library.
it takes in data on ADC0 (Analog0) and processes them
with the fht. the data is sent out over the serial
port at 115.2kb. there is a pure data patch for
visualizing the data.

Aggiornamento In realta' il Jtag USB funziona anche sui moduli cinesi Il problema risiede nell'ID USB della porta Jtag. Nel modulo...
