Learning the Teensy LC: Input Capture

Teensy LC input capture test

As a third step to learning the Teensy LC, I decided to tackle input capture. I discovered that there is no separate interrupt vector for input capture; it is the same vector used by the timer interrupt. This means that if we are looking for a timer overflow event as well as a pin change […]

Learning the Teensy LC: Interrupt Service Routines

Custom ISR in the Teensy LC

As a follow-on to my PWM experiments, I wanted to create a custom interrupt service routine (ISR) in the Teensy LC. This would be similar to using the ISR() macro in an ATmega-based Arduino. Because the ARM has different vectors (and some other weird/cool things, like configurable interrupt priority levels), I knew the normal ATmega […]

Using Python and BLE to Receive Data from the RFduino

Edison and RFduino

It’s should be no surprise that I enjoy working with the Edison. It may not be as easy to work with as the Raspberry Pi, but I still like it. My current project includes getting the Edison to talk Bluetooth Low Energy (BLE) to another device. The RFduino is the device in question, as I […]
