Ian NeillIt was my birthday and my sister got me a "computery thingy toy".
Not an Arduino or a Raspberry Pi.
Seems to be a C8051F330 development board.
Interesting!!!
t_biasπ May this produce joy for some!
#reverseengineering completed now by finding a pattern to light all six LEDs with 3 driver pins. I've put it into a drawing, together with a schematic: each driver pin is connected to four LED pins (two anodes and two cathodes). To leave an individual #LED dark, in its time slot leave one or both drivers high-Z.
They used 5V for the #microcontroller and blue LEDs, because of their forward voltage >2.5V.
They took 200Β΅s per time slot: overall period of 1.2ms.
Gareth HalfacreeAnd finally, there's a new Espressif ESP-IDF out - with a new and more compact standard C library, an Installation Manager that makes setup easier and can manage multiple installations side-by-side, and more!
...including a Model Context Protocol server for those who would prefer to have the Plagiarism Machine write their code for them. Ugh.
Right, about to lock my focus on a newsletter I need to get written by the end of the day - so let's procrastinate just a little longer with today's #Hackster round-up.
First up: a fantastic, but pricey, physical Conway's Game of Life board - built using a cheap microcontroller connected to a large number of expensive self-illuminating tactile switches.
Then a new product from Seeed Studio, the reTerminal D1001 - an 8" full-colour smart touchscreen display with an Espressif ESP32-P4 at its heart.
Shawn HymelNew embedded #Rust video is out! I cover test-driven development (#TDD) by showing how to use Rust's built-in test framework with the sensor library we wrote in a previous episode. Check it out!
