PIC32MZ tutorial -- Timer Interrupt
An interrupt is an internal or external event that requires quick attention from the controller. The PIC32MZ architecture provides a rich interrupt system that can manage up to 190 sources of inte

PIC32MZ tutorial -- Change Notification
In my last post I implement "Key Debounce" with port polling, port polling is not very efficient. And this time, I will use change notification instead of port polling. It generates interrupt and
-
PIC32MZ tutorial -- External Interrupt
In my older blog "PIC32MZ tutorial -- Key Debounce", I shows how to acheive key debounce with port polling. At this moment, I write an application which uses External Interrupt. Therefore, only ge
-
PIC32MZ tutorial -- UART Communication
At this moment, I accomplish the interface of UART communication for PIC32MZ EC Starter Kit. This interface configures the PIC32MZ for communication with a host PC at 115200 baud. There are five f
-
PIC32MZ tutorial -- Core Timer
Core Timer is a very popular feature of PIC32 since it isa piece of the MIPS M4K core itself and is common to all MIPS processors. Most RTOS's timer are based on core timer. This timer has a f
-
PIC32MZ tutorial -- 32-bit Timer
The microcontroller is PIC32MZ2048ECH144 on the PIC32MZ EC Starter Kit. This microcontroller has four 32-bit synchronous timers are available by combining Timer2 with Timer3, Timer4 with Timer5, T
-
PIC32MZ tutorial -- Input Capture
Today I accomplish a simple application for PIC32MZ EC Starter Kit. This application uses Input Capture feature of PIC32MZ. The Input Capture module captures the 32-bit value of the selected Time
-
PIC32MZ tutorial -- Hello World
Today I implement "Hello World" on PIC32MZ EC starter kit. The application of "Hello World" only lights up a LED. There are three LEDs on the starter kit board -- LED1 and LED2 and LED3. At the mo
-
PIC32MZ tutorial -- Key Debounce
Today I accomplish a application on PIC32MZ EC Starter Kit. The feature of application is to light up LED when key released and put out LED when key pressed. LED is the Starter Kit LED1 connecting

PIC32MZ tutorial -- Output Compare
Output Compare is a powerful feature of embedded world. The PIC32 Output Compare module compares the values stored in the OCxR and/or the OCxRS registers to the value in the selected timer. When a

PIC32MZ tutorial -- Blinky LED
Today I finish the "Blinky LED" application on PIC32MZ starter kit. This application let LED1 blink with 0.5HZ frequency. The pseudo code is like LOOP: LED ON Delay 1 second LED OFF D

PIC32MZ tutorial -- OC Interrupt
In my previous blog "PIC32MZ tutorial -- Output Compare", I shows how to apply Output Compare without interrupt to generate PWM signal. I also tried the Output Compare interrupt. I selected OC to

PIC32MZ tutorial -- Watchdog Timer
Watchdog is a very necessary module for embedded system. Someone said that embedded system operates without watchdog enabled just like the car without air bag. You should always enabled watchdog a
