Log in or register, to view the original Good time of day.It is necessary to write a sketch for connecting Arduino nano and TFT display 2.2 SPI 240x320.The essence of the device is one of the analog entries of the arduino we control the voltage from 0.1 to 1.2V coming from the external device (the voltage is constantly changing).The display is a scale of 12 segments, each of which is illuminated when it reaches a certain voltage.Description of work: 1 .We press the SB1 button for 3 seconds - the device is turned on, the black display inserts the white letters of HELLO for 3 seconds.After 3 seconds, the work display is enabled.2ndThe SB1 I SB2 buttons play the role of the shields of transition between the MOD1 and MOD2 objects.(After each device is activated, the cursor is placed on the MOD1.ThreeThe cursor on the object MOD1, shortly pressed the SB1 button, then on the output OUT1 appears the logic 1.This output position remains until we again press the MOD1 object with the SB1 button, after which the output again appears 0 (simply, the MOD1 object is the fixation button to turn the HL1 lamp on or off).4 .The SB3 button (the shot to the right) moved the cursor to the MOD2 object.Press the SB1 button on this object shortly.The signaling system has been activated.The essence of the mode is that it is attached to our 12-segment scale, when it reaches the 4 segments and more on the output OUT2 appears a sequence of 1.0,1 ... (HL2 indicator begins to blink, a second bright, a second break ...).The HL2 indicator shines until the scale decreases below 4 segments.When the HL2 indicator falls below 4 segments, the HL2 indicator starts shining again when the 4 and more segments are reaching.To turn off the alarm mode, we shortly press the SB1 button on the MOD2 object.and 5.By pressing the SB1 button for 3 seconds, we completely disable the device.Measurement of voltage at the entrance: On the Arduino entrance is the voltage that we control (from the external sensor) that varies from 0.1 to 1.2V.Our task is to measure this tension within 0.2 seconds.as many times as possible, and the highest value that was recorded in 0.2 seconds to be displayed on the scale without delay.Tension on the scale: The scale has 12 segments.The change in the number of sealed segments is logarithmic.Stage of segments: 1 to 0.1b 2nd 0.12b 3) of 0.14b 4) of 0.17b 5) of 0.21b 0 0 0 0 0 7) of 0.35V 8) of 0.45v 9) 0.58b 10) 0.73b 11) 0.92v 12)> 1.16b Use of real-time schedule: This schedule is linked to a scale.In the right part of the neck is a red circle, the position of which is attached to the segment that is at the moment enlightened (the top).When the voltage changes at the entrance, the number of lighted segments changes and accordingly, the red circle moves up or down after the top segment.The left side of the red circle is a line that shows changes in tension over the last 3-5 seconds.
