futz f&ts v.i. To tinker experimentally; to change something just to see what it does

I wrote some code for the PyBoard to drive a TM1637 4-digit 7-segment LED display. The code is basically I2C with no slave, so not terribly difficult to bit-bang.

Then I modified that code to use the PyBoard's RTC to work as a clock. That worked fine, so I thought I would get it going on the Trink...

I've been interfacing the pyboard to all kinds of stuff to get a bunch of coding and practice under my belt before I really try to do something like a robot with it. I've ported my 5110 LCD C code for PIC to MicroPython, and connected things like servos, a HY-SRF05 ultrasonic range sensor, a Sharp G...

I ported my 7110 LCD C code for PIC to MicroPython on the PyBoard. It wasn't very difficult. Yet again, most of the trouble I had was due to having to learn Python as I ported the code. Not a big deal - Python isn't difficult to learn.

I wasn't sure about text formatting for my font array in Pytho...

After tinkering with the Adafruit Trinket M0 for a short while I ordered a STM32F4 MicroPython board from icstation.com. When I got it I dropped it in a box and forgot about it for a year or so. When I finally went to play with the board I saw that it had "TPYBoard" printed on the back, so I googl...

Another Bluetooth module to test. This one is the KCR-86B v4.0. No idea where I got it (probably Ebay), but they're available all over the interweb. This module is Bluetooth 4.0, obviously.

No USB and TF card socket connections on this one, but it does have a stereo aux input. It has LED indicator...
