• Here's some code...

• PCB beginnings

  bret.wiebe • 07/29/2015 at 20:28 • 0 comments

  Just rediscovered Upverter, have started learning the ropes and creating my schematic. The goal is to layout a pcb for the "permanent" version of this thing. I have some protoboards that I could use, but as a large motivation behind this endeavour is to learn new stuff I would prefer to get some experience with producing a pcb layout.

• Some (more) progress

  Here's a schematic of the current setup. Had to do a little connection shuffling to free up digital pin 2 for the external interrupt, using the tact switch to change modes (poem, clock, compass). Next step is to gather the useful parts of my various test sketches into a functioning unit and tweak the poetry portion.

• Some progress...

  The two modules arrived and I assembled the DS1307 RTC kit. The basic code for generating the "poems" is working (still on the Pro Mini). I attempted to compile it for the Teensy-LC but got an error related to the library I'm using for the seven segment display and a warning related to using an array of strings. I'm debating whether to figure these issues out now before proceeding with the Teensy-LC or if I should continue with the Pro Mini and then adapt for the LC later. Any ideas of alternative ways to handle the seven segment display on the Teensy?

• Parts acquisition

  Just ordered the RTC and magnetometer modules. Decided on the LSM303 triple-axis accelerometer and magnetometer from Adafruit as the feature/price factor seemed like the best value. Continuing to sketch ideas about how to use the seven segment display in various ways and reconfigured the circuit-thus-far on the breadboard to make room for the two modules.
