time, date, and the maximum temperature for tripping temperature (including cooling fan). When you press the MENU button we get to the sub-menu to set the parameters. This mode works as the key SET, while you click on that for about 3 seconds displays the values of temperature sensors. Main Menu Management amplifier consists of the following items: Volume (Volume) Attens (Gain) Bass (Bass) Treble ( Treble) Balans F (Front speaker balance) Balans R (rear speaker balance) and as previously described, the movement through the menu buttons UP / DOWN (keys and remote), but adjusting keys LEFT / RIGHT (and the tuning knob). Turning counterclockwise - simulates pressing the LEFT. When rotating clockwise - simulates pressing the RIGHT. Versatile has not turned out (but I decide this problem.) Here is a diagram and pattern of the printed circuit board assembled tuning knob on the basis of the engine: In the end, I got reliable operation and industrial walkover.īut the negative point still remains, it is different microcontroller firmware for different types of tuning knob (motor industry). I will not describe the "war" with these.
Valkoder not worked steadily and missed pulses (the reason was because of the bounce). Realizing that not everyone has the opportunity to find an engine, I ordered the industrial walkover, and when he came, I started experimenting with it. Program for processing to be simple and very good work. Walkover earned immediately and as it turned out, then has another advantage - it does not bounce (he has not physically). Since it (the engine), I had decided to apply it, and as it turned out for good reason. Climb over the Internet, I found that suited me - it's the tuning knob on the basis of the stepper motor from the old 5 inch floppy disk drives. Here it is:Īt the beginning of the development I did not have the industrial walkover, had to think of something. circuit board for the keyboard at first I did not want to provide, since it depends on the design of housing and personal preferences, the placement of buttons and everything else. This is done to avoid triggering an accidental click on these buttons especially if you use the remote control. MUTE buttons and LOUDNESS about 1 second. Key button practiced the program almost immediately, but the depression and the response to the STANDBY requires pressed for about 3 seconds.
LEFT / RIGHT - increase / decrease in the relevant parameter that is displayed on the LCD. UP / DOWN - Move to the previous / next menu or submenu The main pressing the SET button you can see the temperature of radiators, the information is displayed within 2-3 seconds. SET - as mentioned above, it is save the new settings in the submenu. For the new settings have been saved, you must click on SET. Pressing this button In this mode, you return to the main menu amplifier control without changing the settings. MENU - button to enter the sub-menu, it is possible to set additional parameters, such as time, date, temperature operating temperature sensors control radiators Disconnects the power amplifier and its power supply, processor module operates in standby mode
MUTE - Mute (shutdown occurs gradually rather than abruptly ). The keyboard is built into an array of 12 buttons (4x3):
