  1. MicroprocessorsA practical approach. 16-08-11 1

  2. Subjects • Goals for this module • Results • Subjects of the module • Plans • Questions 16-08-11 2

  3. Goals • Students are able to build, program and document a little microcontroller system. • microcontrollers sensors /actuators 16-08-11 3

  4. The practice is obligatory • Attending the practical lessons is obligatory. • Not possible to attend the practice? contact dhr Stokkink • Failing to attend more then 2 practical lessons, there will be no grade! • During the practical lessons the logbook will be assessed 16-08-11 4

  5. Assessment • The logbook will be looked at as an assessment • Home-orders will be assessed sufficient or insufficient. • All home-orders must be sufficient in the end. 16-08-11 5

  6. Responsibilities • The student is responsible for the hard-en software, there are more groups who must use it. • Defects must be reported immediately. 16-08-11 6

  7. Subjects. • Architecture PIC16F690 • Hardware /software practical • Delays / Flash led / • Digital input /counters • Analogue input/ analogue sensors • PWM/ motorcontrol • Other processes 16-08-11 7

  8. Subjects week 1 • Architecture. PIC16F690 and PIC family • Features • Pin out • Device overview • Memory organisation • Clock sources • Digital Output 16-08-11 8

  20. Practical • Each week an introductory assignment • At the beginning of the week the home assignment must be shown on the test board. Is must be through a flowchart and the program in your logbook. • Software is free at www.microchip.com en http://www.bknd.com/cc5x/ • Download datasheets and bring them to the lessons. • Assignments can be found at http://lesmateriaal.saxion.nl/stk 16-08-11 20

  21. Assignment 1 • Install MPLAB • Installing CC5x c-compiler • Questions, assignments • Example program • Simulation • Test 16-08-11 21

  22. MPLAB IDE 16-08-11 22

  23. Home assignment 1 • Connect a LED and resistor to RC4-RC7 and test each LED with a program • Make a program and simulate, that has a function to give a value 0-255 to the LED’s 16-08-11 23
