Menu

very brief description of the function of the push buttons, encoders and encoder buttons

There are two menus with different menu points where the use can adjust settings, Menu1 and Menu2. Menu points are displayed in the two boxes at the bottom right of the TFT display. The upper box belongs to Menu1, the box in the middle belongs to Menu2. The lowest box shows the setting of the parameter, either that of the corresponding Menu1 OR Menu2 point. Which one is shown, is indicated by highlighting the menu point with white letters on blue background. Once you use it, it will become clear, I think.

There are five buttons B1 - B5 and three encoders E1 - E3, each encoder with an additional pushbutton EB1 - EB3

BUTTON	TEENSY PIN	BUTTON NAME in code	DESCRIPTION
B1	pin 33	button1	band-
B2	pin 34	button2	band+
B3	pin 35	button3	change mode
B4	pin 36	button4	menu point-
B5	pin 37	button7	menu point+

ENCODER or BUTTON	TEENSY PIN	BUTTON NAME in code	DESCRIPTION
E1 = encoder	pin 16 & 17	tune	tune / change frequency
EB1 = encoder button	pin 38	button5	toggle tune step [1Hz, 100Hz, 500Hz, 5kHz/9kHz]
E2 = encoder	pin 1 & 2	filter	filter bandwidth
EB2 = encoder button	pin 0	button6	SNAP carrier function OR menu1 toggle button
E3 = encoder	pin 4 & 5	encoder3	Volume / other settings from Menu2
EB3 = encoder button	pin 8	button8	menu2 toggle button

I will try to give a very brief overview over the functions of the buttons:

B1 / B2:

• switch band up/down

B3:

• change demodulation mode

B4 / B5:

• step up/down in menu points

E1

• tune encoder / change frequency

EB1

• toggle between tune steps

E2

• set filter bandwidth

EB2

• SNAP function to snap to a carrier (+- 4Hz accuracy)
• when you are in specific menu points (which require a YES/NO decision), the function changes to this decision (for example: Save Eeprom, Load Eeprom, IQ Auto, Reset codec, Show spectrum)

E3

• sets all the settings from Menu 2 (eg. audio volume, RF gain and many many more . . .)

EB3

• toggles settings from Menu 2, when appropriate (LMS type, type NR, X or E in NR)

One question remains:

How can you change between Menu 1 und Menu 2 ?

• turn encoder E2 --> you are in Menu 1 and can choose between menu entries with buttons B4/B5

• turn encoder E3 --> you are in Menu 2 and can choose between menu entries with buttons B4/B5

• turn encoder E2 again --> you are in Menu 2 again . . .
