Using pk2cmd to transfer a hex file onto the dsPIC30F4011
Since upgrading to MPLAB X, I’ve had difficulty using the PICkit2 from within the IDE, so I’ve mainly been using the PICkit2 helper application to transfer my compiled hex files to the dsPIC. However, there is another handy way of … Continue reading
PWM generation with the dsPIC30F4011
This is a simple example of PWM waveform generation using the dsPIC30F4011 microcontroller. This chip has three PWM channels (pins 33-38), each channel consisting of a pair of pins which can be configured in various ways. The code below enables … Continue reading
Printing text from the dsPIC30F4011 to a PC via UART
This is a simple example of sending text from a dsPIC30F4011 microcontroller to a PC via the UART. This program toggles an LED on RD0 once every second. Each time the LED is switched on or off, the word “Hello” … Continue reading
Creating a new XC16 project in MPLAB X
These are the steps I use to create a new MPLAB X project for a C program compiled with Microchip’s XC16 compiler: From the File menu, select “New Project…”. The new project dialog box will appear. Choose Project: Select “Microchip … Continue reading
Next programming workshop: 2-4pm Thursday 30-8-2012
I’ m planning to run another programming workshop next Thursday, 30th August 2012. This workshop will build on the dsPIC basics that we covered in the previous workshop. Basically, I’d like to give a short guided tour of what I … Continue reading
