Currently, we can see how to read an exterior analog signal using a PIC microcontroller and display the digital output conversion on an LCD display. These signals need to be changed into digital before being treated by the microcontroller. Analog to Digital ConversionĪnalog to digital converter is essential in an embedded system because, while these systems deal with digital values, their surrounds usually involve various analog signals. These microcontrollers are somewhat inexpensive and can be bought as kits or pre-built circuits that can be designed by the user.
PIC microcontrollers are programmed and replicated by circuit wizard software. The applications of PIC microcontrollers mainly involve in various electronic devices like electronic gadgets, computer control systems, alarm systems.ĭifferent types of PIC microcontrollers exist, while the finest is probably found in the GENIE range of programmable microcontrollers. The production line can be controlled by a preprogrammed microcontroller with timers. The term PIC stands for programmable interface controllers, which can be pre-programmed to carry out a huge variety of tasks. ADC in PIC Microcontroller Analog to Digital Converter in PIC MicrocontrollerĪnalog to digital converter in PIC microcontroller is discussed below. Please follow the following link for Types of analog and digital sensors with applications.
Some examples of analog devices are temperature, light, touch, accelerometer, and microphone for recording of audio. This allows us to interface all types of analog devices with a microcontroller unit. To rectify this problem most of the microcontrollers have an analog to digital converter units which will convert from a voltage to a number so that it can be handled by a digital system like microcontrollers. So we cannot directly measure voltage from microcontrollers. For example, if i/p is greater than 2.5v then it will be read as high (1) and it is less than 2.5v then it will be read as low (0).
