How to use PIC12F675 Microcontroller

Before using a microcontroller in a system or application, it must first be programmed. So, first and foremost, we must program the PIC12F675 controller.

The entire procedure for programming the PIC12F675 is as follows:

• First list all the functions to be executed by this controller.

• Next write these functions in ‘IDE software’ using a relative programming language (use ‘C’ language in MPLAB  IDE ).

• After writing the desired program compile it for error elimination

• For a successful compilation IDE application generates a HEX file for the written program

• Choose the programming device (usually ‘PIC kit 3’ or ‘PIC kit 2’) which establishes communication between PC and PIC12F675 

• Connect the programming device to the microcontroller appropriately

• Run the HEX file dumping software which is related to the chosen programming device

• Choose the appropriate program HEX file and burn this HEX file in PIC12F675 flash memory

• Disconnect the programmer and connect the appropriate peripherals for the controller

After plugging in the electricity, the controller runs the HEX code stored in the memory (which is a written program) and generates the desired response.


PIC12F675 Ultrasonic Proximity Detector Circuit Diagram

The ultrasonic proximity detector circuit  PIC12F675 detects a distance of about 30 cm to 3 m mounted on the microcontroller.

The rotating time of the radiating ultrasonic wave reflected from any object is used to calculate ultrasonic distance. The design is as basic and tiny as feasible, thanks to the Microchip PIC12F675 microcontroller and integrated hardware functionalities, and the circuit is mounted on a PCB board.

The reflected wave connects the signal amplified with the  NE5532  to the input of the PIC12F675 microcontroller's inbuilt comparator (pin 6).

An internal reference is set to the comparator and the decision level is modified inside the PIC12F675 Microcontroller. Changing its value (VRCON recording) makes adjusting the circuit's sensitivity to the input signal a breeze. The sensitivity is now tuned to the lowest feasible value thanks to the adoption of a high-quality operational amplifier in the IO1 position.

R6 is attached to the internal A/D converter's input, which continuously monitors its present position. It is utilized as a decision level for measuring the ultrasonic wave's reflection duration, and the software limits it to a range of around 30 cm to 3 m.

The microcontroller output (pin 7) and then the output transistor T1 will open if the reflected wave is set or detected at a lower range/distance, for example, to control the relay, buzzer, or any other system. LED D1 turns on the output, which remains open for the duration of the obstacle detection period within the set distance.

The ultrasonic sensor circuit is designed with DIP and SMD type 2  PCBs . SMD source asm and hex software files come in two flavors: double-layer and single-source.
