On my last post I had barely scratched the surface of what the LP55231 could do and was reading about the three program execution engines. After a bit of research I found that TI supplies a dashboard program and an assembler for the chip, but only for their own LP55231SQEVM evaluation board.
The...
I bought a Sparkfun BOB-13884 LP55231 breakout board as filler on a recent Digikey order. The LP55231 is quite an interesting chip. It drives only 9 LEDs, but has a pile of capabilities. And with the onboard charge pump it does it all on low power and very efficiently. Way too much to type, so her...
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...
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...
