MicroView GPS – displaying data

Introduction

This builds on Project 006a, in which we simply connected a GPS unit to our Microview and checked we were getting some data.  Now to make some sense of that data and display it!

This is a bit of a step-up in terms of code, which is why I have left an intermediate Project 006b available in case I need to retrace.  I’m sure people will let me know..

MicroView sliders with text labels using RGB LED

Introduction

It’s possible to draw multiple components of different kinds on the MicroView screen at once.

In this blog, the three inputs to an RGB LED are controlled using pulse width modulation (PWM) signals.  The three sliders are set up with simple labels ‘R’, ‘G’ or ‘B’ to the left.  Each colour is raised to full brightness, then dimmed in sequence.  The sliders show this graphically and display the current PWM value from 0-256 in real time.

Circuit

Pins referenced in code as 3, 5 and 6 (numerical pins 12 to 14) are capable of PWM on the MicroView.  These are connected to the LED via 330 ohm resistors in the usual way, with the COMMON of the LED connected to pin 8 (GND).

MicroView Education Kit – first look

I have just received the MicroView Education kit, the result of a Kickstarter project by the team at Geek Ammo and I’m pretty impressed.

Hardware Overview
The hardware is distributed by Sparkfun and essentially comprises the MicroView with the accessories normally included in the (Arduino) Sparkfun Inventors Kit.  There are many tutorials and books that use these components and as the MicroView has the same functionality as the Arduino Uno, they can all be used.
