Step-by-step PICSimLab tutorials: PIC microcontroller projects, spare parts and virtual instruments, with example XC8 code.
Store Data in PIC16F877A EEPROM with PICSimLab RAM forgets everything at reset; the PIC16F877A’s internal data EEPROM does not. This tutorial keeps a running counter in EEPROM: every button press increments it, the value appears on LEDs, and after a reset the counter continues where it left off — the classic test that non-volatile storage…
PIC16F877A Timers and Interrupts in PICSimLab Delay loops waste the CPU and make timing drift whenever the code changes. The grown-up pattern is a hardware timer raising an interrupt at a fixed rate. This tutorial blinks an LED from a Timer0 interrupt on a PIC16F877A in PICSimLab, and shows how to verify the timing with…
PIC16F877A UART Serial Communication in PICSimLab Serial output is the embedded developer’s printf: once the UART works, every later project gets easier to debug. This tutorial sends and echoes text from a PIC16F877A in PICSimLab at 9600 baud, 8N1 — and it starts with the one prerequisite that most beginners miss: the desktop simulator needs…
Read a Potentiometer with the PIC16F877A ADC in PICSimLab Analog-to-digital conversion is where a simulator earns its keep: you can turn a virtual knob and watch the digital result change instantly. PICSimLab’s Potentiometers spare part provides four potentiometers, and the PIC16F877A has a built-in ADC — this tutorial connects one to the other and shows…
Multiplex a 7-Segment Display with PIC16F877A in PICSimLab Four-digit 7-segment displays are wired with shared segment lines, so the firmware lights one digit at a time and cycles fast enough for the eye to see a steady number. PICSimLab’s 7 Segments Display spare part exists in exactly this form — four multiplexed displays (or a…
Read a Matrix Keypad with PIC16F877A in PICSimLab A matrix keypad teaches row-and-column scanning: drive one row at a time, read the columns, and work out which key is pressed. PICSimLab provides a Keypad spare part, so a PIC16F877A project can practise the full scan loop in simulation, with no wiring mistakes possible. What you…
Drive an HD44780 LCD with PIC16F877A in PICSimLab A character LCD is usually the second project after the LED blink: it proves you can drive a multi-pin peripheral with real timing. PICSimLab includes an LCD hd44780 spare part, so you can wire a text display to a PIC16F877A, print messages from XC8 code and debug…
Blink an LED with PIC16F877A in PICSimLab Blinking an LED is the “hello world” of microcontrollers, and it is the fastest way to prove your whole PICSimLab workflow works: board selection, project generation, compiling with XC8, loading the hex file and running the simulation. This tutorial uses a PIC16F877A, the most documented PIC in PICSimLab,…
