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 match occurs, the Output Compare module generates an…

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 be PWM mode without fault pin (OCM = "110&qu…

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 generates interrupt and starts debounce when the f…

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 functions in the interface -- Uart_Init(), Uart_Getc(),…

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, Timer6 with Timer7, and Timer8 with Timer9. The 32-bit…

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 to RH0. Key is the Starter Kit push button SW1 conne…

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 moment, I only light LED1 on RH0. Every…

http://www.cs.indiana.edu/~geobrown/book.pdf An example of a basic timer is illustrated in Figure 10.1. This timer has four components – a controller, a prescaler (PSC), an “auto-reload” register (ARR) and a counter (CNT). The function of the prescal…

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 as possible as you can. The PIC32MZ Watchdog Timer (WDT…

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 Base registers when an event occurs at the ICx pin.  T…
