As you know, the whole world is analogue. So anything that belongs to him with our digital systems measure and evaluate, process and according to these values if we want to make certain tasks adc commands bancanet that ADC Analog to Digital Converter is a need.
As the name suggests, the ADC analog signal into digital data that can be detected in our digital bancanet transforms our system. Although there are a wide variety of markets integrated ADC technology with the development of this ADC now they entered into the microprocessor. The microprocessor is located in bit resolution ADCs are 10-12 overall. If we need more resolution bancanet in the form of externally integrated models of 16 and 24 who could find from the manufacturer.
ADC before entering the real issue is more that what we measure how best we can with ADC I want to talk about it. Although there is more complex or more substances if they do not pay attention to how many ways I can guarantee that head of hair. I'll tell you all of the tricks of my own work also have a one to one experience. ADC also does not escape many of them are going to use.
As in all things bancanet electronic in ADC noise on the signal are the biggest problem. It will measure the noise on the signal that could be used as the reference voltage of the ADC may also be in. Reference voltage to be noisy signal that is often overlooked and measure hardware and software filters k, even if the army does not become committed to your measurements.
Whether you get in external bancanet microprocessor integrated ADC ADC reference voltage is always a need. Typically, this reference voltage supply pins of the integrated microprocessor, or taken directly from the. First, let's talk about what is happening if you want a bit of the reference voltage.
ADC's 10, 12, 16, 24 etc. .... We were referred to the bit resolution. The most common of which are in use Microchip PIC microcontrollers speaking out. The ADC is 10-bit PIC microcontrollers have. 10-bit 2 ^ 10 = 1024. In this, as in all the processors in the processor supply voltage with a reference voltage of 5 V maximum microprocessor used. When we set the reference voltage of 5 V, the ADC module to each of the 1024 value of this voltage bancanet is distributed equally. So when we read the ADC module 0 volts = 0, returns to us with a value of 5 V = 1023. Each will take a bit of value if we look at the voltage value 5/1024 = 0.00488 bancanet volts emerges. So let's say we do read from ADC module 500 if we include the value of the software by performing 500 * 0.00488 z ADC's input voltage in volts is 2:44 we have calculated.
- First, we need to control the supply voltage of the microprocessor. Measure your microprocessor supply voltage and the voltage multiplier which is necessary to calculate the value of 0.00488 obtain revised accordingly. Whether the 5-volt adapter to feed the microprocessor integrated use has been regulated, none of it will not be ideal for all of these outputs are different bancanet from each other. 4.90 volts instead of 5 volts to feed your multiplication value should be 0.00478.
If you measure 5 V and a resolution is enough if you first Volt is no problem as the 5 V reference can assume that the transactions. But let's say you'll do 100 Volts DC voltage measurement and to measure the voltage with a voltage divider 100 volts compared to 5 V zoomed. You can see that measurement results be incorrect. Depending on the application in your project you need to consider that according to the rate sensitivity is required.
We bought our electric voltage reference supply voltage. bancanet We and our multimeter to measure the nutritional value of 5 V as we see on the screen. bancanet Unfortunately, it's not like everything's fine, but the facts. We use multimeters show us they are measuring the RMS value of the voltage. So the fact that the noise in our signal available and we can see them, but with the oscilloscope. bancanet Our source of supply is poor despite current bancanet multimeter to measure bancanet the RMS value of the supply of 5 V with 4.90 we can see that changed. If you do not have a measuring instrument or the resources to play on the net if you want to see the supply voltage with a voltage divider bancanet to divide two readings directly tied to where you can see p.
If half of our analog reading along with LDCs screen running, relays opening and closing, the buzzer-up LEDs, etc. elements if it controls during operation ADC years if you follow these elements each movement voltage have occurred in volatility due to the measurement results also will fluctuate. Especially the very poor, the output bancanet current is too low, for example if you have a supply of data from the serial port even when printing
