help with understanding the code

Post by nova »

In the function tune_rf is the "pll_rfin_pin" a digital input coming from the pll(some kind of lock function pin)?

when "set_resistor(BANDWADJ2_RES, 0);" is used, is the ramp signal at it's maximum or its min amplitude?

in the function tune_rf_band does the pll get programmed to start at the center frequency and then the min frequency?

final two questions

once the bandwidth is stored in memory does this value change while the microcontroller is running or is this value constant?

also does the ocr1a and ocr1b values change once stored in memory and the program is running on the microcontroller?
