+# How to use this
+
+ * Display on PB8/PB9 for SCL/SDA
+ * Analog is on PA7
+
+First, use FFT, then look in the middle for the highest bin @.  This is the # of pixels from the left side of the screen you are.
+
+Then edit ttest.c, 
+
+```
+	g_goertzel_omega_per_sample = (47.0/256) * 3.1415926535*2.0*65536;
+```
+
+where 47.0 in this case is the bin # from the FFT.
+
+Change this, `make test`
+
+Then copy the values:
+const int32_t g_goertzel_omega_per_sample = 75599;
+const int32_t g_goertzel_coefficient = 870257651;
+const int32_t g_goertzel_coefficient_s = 1963246708;
+
+into the top of adcgoertzel.c
