Seth Stoothoff recently published a detailed tutorial on Instructables, for a chipKIT Parking Obstacle Sensor. The project uses a chipKIT Pro MX4 dev board from Digilent, and a Maxbotix Ultrasonic Range Finder.

The obstacle sensor uses an LCD to display the distance in inches, cm, or mm depending on the "units" variable selected in the code. It also

Did you know that chipKIT boards can also be used as generic embedded controllers? chipKIT-compatible boards can be programmed not only with MPIDE or UECIDE, but also in several other IDEs using programming languages such C, C++, Pascal or Basic. When using another IDE such as MPLAB X, the chipKIT bootloader may become erased or over-written, which is fine, if you plan to stick with that

So you have a chipKIT Pi, which you have dutifully attached to a Raspberry Pi, and you'd like to deploy it "in the field" (with the cows). That's fair enough. What you'd like to be able to do, though, is upgrade the firmware on the chipKIT Pi without having to go into the field (those cows are scary, man!).

So how would you do that? You can't program the chipKIT Pi without pressing the RESET and BOOTLOAD-EN buttons (and you're not about to train cows to do that for you), so what are your options?

Well, UECIDE has the answer for you.

chipKIT lovers rejoice! Incorporating peripheral interrupts into your sketch has never been easier. In a previous post, we discussed how you can schedule operations to run periodically in your sketch by using the Task Manager, but for certain applications (such as audio sampling) you need more exact timing than the Task Manager can provide. In such cases, you can use hardware interrupts.

Today's post shows how you can use the built-in ease-of-use of the

I have just finished writing up a new tutorial on using the Nokia 5110 graphical LCD with the chipKIT platform. Nokia 5110 LCD was used in Nokia's popular 5110 and 3310 model cell phones and is a very popular display among the Arduino community because of its low cost (~$3 on eBay). It is a 48×84 pixels matrix LCD driven by the low-power PCD8544 controller chip. It is powered by 3.3V and includes on-chip generation of LCD supply and bias voltages, thus requiring minimum external components for its operation. This tutorial explores the PCD8544 serial bus interface and its connection with chipKIT Uno32
