Just want to connect the programmer to my dev board, leave the chip in place, Useful for programming one off chips but you have to insert and remove theĬhip that you are programming moving from the programmer to the development Test the microcontroller program while the programmer is still attached.Ĭleverly uses the serial port to provide a high voltage programmer that does The programmer should isolate the microcontroller so you can High voltage programmer (but see bootloading). The serial port generates higher voltages and this fact is usedīy programmers such as a JDM pic programmers. Logic levels are nominally 5v so usually these programmers require use of anĮxternal power supply to generate the higher voltage. Voltages from the parallel port or USB port are not that high. The 13.5 volt level complicates the interface circuit since the The pin is (MCLR) 14V but on some newer PIC micros this is lowered to 13V so be Source : PIC application note ICSP (DS30277) To suitable logic levels for the microcontroller - most levels are ok as theyĪre, but for 'normal' (or high volt) programming of a pic microcontroller theįollowing voltage at the MCLR pin is needed: The pic programmer translates digital logic levels from the PC To the microcontroller and read it back for verification. Microcontroller using the PC's parallel,serial or USB port. Future embedded system laboratory session could be designed around ATMel lines of Microcontrollers.A pic programmer is a circuit which interfaces the PC to the

Laboratory session with the development board and software demonstrated in this article is unambiguous. Our years of experience in the teaching of microcontroller course and the active involvement of students as manifested in complete in-depth hands-on laboratory projects on real life problem solving.

Each of the experiments was carried out using BK300 development board, PICKit3 programmer, Proteus 8.0 software. This is to help students connect their theoretical knowledge with the practical experience. Also, developments of software code, circuit diagram simulation were carried out.

In this paper, we solve the problem of student comprehension and skill development in embedded system design using microcontroller chip PIC16F887 by demonstration of hands-on laboratory experiments. Microcontroller system is one of the vital subjects offered by students during the sequence of study in universities and other colleges of science, engineering and technology in the world.
