پاسخ : ساخت یک پروپ همه کاره

بادرود از شما و طرح کارآمدی که آپ فرمودید مهندس عزیز کلید های BUT1 و BUT2 در مدار کارشون چیه ؟ولتاژ کار مدار ( بعد از آیسی رگلاتور) چقدر است؟ فایل نرم افزاری مدار را در سایت آپ بفرمایید. ودر کل یه توضیح کوچک راجب پارامتر های قابل اندازه گیری توسط این مدار . ضمنا PCB مدار را آپ بفرمایید.باسپاس همواره سبز و پیروز باشید.

پاسخ : ساخت یک پروپ همه کاره

خواهش میکنم
شما اگه یک کلید بگیرید و کلید دوم (فرق نداره اولی کدومه) کارکردش عوض میشه . مثلا توی حالت اول یک پروپ هست که 1 یا 0 بودن تشخیص میده
یک بار دیگه بزنی تبدیل میشه به فرکانس متر
بار بعد ولت متر - تولید فرکانس 38 کیلو - تولید pwm - تولید فرکانس های مختلف که اگه فقط یکی از کلید هارو بزنی فرکانس از 1 هرتز تا چندین کیلو تغییر میکنه - تست پورت سریال روی باد ریت های 1200 / 2400 / 4800/9600 که با فشار یکی از کلید ها حروف A تا Z برات میفرسته
خازن سنج داره که خازن های ظزفیت پایین نمایش میده
تست دیود داره
تایمر داره
کانتر پالس داره
زمان شمار داره
......
PCB اون هم آپ کردم لینکش مشخصه

Prob	Logic Probe	The logic probe shows 'H' for high (over 3.7 volts), 'L' for low (below 0.8 volts) and '-' for floating in the first display location. If a pulse is detected (0.5 usec minimum), the second location flashes a 'P'.
PULS	Logic Pulser	The logic pulser shows the pulse rate (5, 50, 500, 5.0) in the last 3 locations. The first location shows the sensed logic level as a dash in the bottom or top of the digit. When button #1 is held down, a series of 0.5 microsecond pulses are generated in the opposite direction and the center segment is lit. Pushing button #2 cycles thru the 4 pulse rates. The selected pulse rate is saved on power down.
FrEq	Frequency Counter	In the frequency counter mode, hitting button #1 switches the display to the next 4 digits of the count. For instance, the display shows '12.57' for a frequency of 12,576 hz. Holding down button #1 shows '2576' - the lowest 4 digits. If a decimal point shows, the value is in Khz, if the decimal is flashing, the value is in Mhz. Hence, a frequency of 42,345,678 hz is displayed as 42.34 with a flashing decimal. Holding down button #1 in this case will display 5678.
Cnt	Event Counter	In the event count mode, the display shows the lowest 4 digits. Button #1 switches to the next higher 4 digits while held down. Button #2 resets the count.
VoLt	Voltmeter	The voltmeter uses the power going into the probe as a voltage reference. The current implementation shows only an approximate voltage - about 2% high. This can still be very useful for most measurements. Do not connect the probe to voltages that exceed 5 volts under any conditions.
diod	Diode Junction Voltage	This is just the voltmeter function with 10k resistor feeding current to the probe tip. When a diode or transistor junction is connected from the tip to the ground lead, the drop voltage is displayed.
Cap	Capacitance Measurement	When a capacitor is connected from the tip to the ground lead, and button #1 is pushed, its value is displayed. Values from .001 uf to about 500 uf are displayed. The larger the capacitor, the longer it takes to measure. A value of 100uf takes a couple of seconds.
Coil	Inductance Measurement	When an inductor is connected from the tip to the ground lead, and button #1 is pushed, its value is displayed. Values from 0.1 to 999.9 millihenries are displayed. Note: this function assumes that the DC resistance is not more than a few ohms. Also, if the unit gets 'stuck' in this mode, jumper the tip to ground to free it.
SIG	Signal Generator	This mode generates a 500hz square wave at about 0.5 volts. The signal is only generated while button #1 is held down.
ntSC	Video Pattern	Generates an NTSC video frame with a white dot pattern.
9600	Serial Ascii	Each time button 1 is pushed, the letters A-Z followed by cr/lf is generated. Auto polarity sensing. If the signal injection point is originally high, then normal (zero start bit) ascii is generated. Otherwise, the other polarity is done. New feature: Button #2 cycles thru 1200, 2400, 4800, 9600 baud.
Midi	Midi Note	Sends note number 60 (middle C) on any of the 16 midi channels. Holding button 1 sends 'note on'. Release of button 1 sends 'note off'. Button 2 cycles thru the 16 channels. The midi channel number is stored.
R/C	R/C Servo	Generates 1ms to 2ms pulse for r/c servos. Button 1 increases pulse, Button 2 decreases pulse. Defaults to 1.5 ms each time mode is entered.
[ ]	Square Wave	Generates 1 - 9999 hz square wave. Button 1 decreases frequency, Button 2 increases frequency.
Prn	Pseudo Random Number	Generates 10khz digital PRN series.
ir38	IR LED	Generates 1 millisecond on and 2.5 millisecond off of 38khz square wave. When connected to IR LED, used for testing IR receiver modules.
PWM	Pulse Width Modulation	Generates variable pulse width 3-97 percent of a 6khz (approx) digital signal. Button 1 decreases pulse width, Button 2 increases pulse width.
StOP	Stop Watch	Button 1 starts/stops timer. Change of state on probe tip also will start/stop timer. Button 2 resets timer. Timer counts in 1/100 seconds from 0-99 seconds, then counts in 1/10 seconds from 100-999 seconds, then counts in whole seconds from 1000-9999 seconds (about 2 hours 46 minutes).
