RP2040 Circular Display MicroPython Driver Code

This is code I have modified, slightly, to define new colors. It was included in the DEMO file from Waveshare. from machine import Pin,I2C,SPI,PWM,ADC import framebuf import time I2C_SDA = 6 I2C_SDL = 7 DC = 8 CS = 9 SCK = 10 MOSI = 11 RST = 12 BL = 25 Vbat_Pin = 29 […]

The Versatile RP2040: a Look at the Waveshare Circular Display with Embedded RP2040

This little gem, which cost around six dollars, US, features a gyroscope, accelerometer, on board clock, temperature sensor (a feature of the RP2040) and the built in circular display at 1.28 inches. With a resolution of 240 x 240, there’s quite a bit you can do with the board. Due to its size and shape, […]

Running Tiny Basic on the Micro: Bit

I was looking for some things to use in teaching my kids some programming with the BBC Micro: Bit and came across Tiny Basic on the Micro: Bit. The implementation of Tiny Basic is a cross between Arduino Tiny Basic and Palo Alto Tiny Basic. It’s very comprehensive and includes things like LED control, sensor […]

BBC Micro:Bit

The BBC Micro: Bit is, to say the least, an outstanding product. Designed to give the youth of Great Britain a headstart in the world of computing, the device made its way outside of the UK and has been available in the US for a time now. I decided to give it a spin and, […]

Building your own programmable clock

Wow, it’s been quite a while since the last posting. I thought we would start the year off with a cool project, a reboot of my Half-Byte Clock, featuring Embedded Tiny Basic. This time, I use an Arduino Nano and a nice canvas/wooden ‘case’ to house it all. Instead of using the somewhat large Half-Byte […]

Using Half-Byte Embedded Tiny Basic to Teach

It is 2017 and we have a slew of low cost or free tools available that teach anyone how to program a computer. Just for Windows, we have something called Small Basic, from Microsoft. It is free and has a bunch of material you can use to teach anyone, especially children, how to code. There […]

Assembling the NKC 65k Color LCD Shield

The NKC 65k Color LCD Shield isn’t difficult to assemble, it is, however a bit time consuming. The most difficult part of the assembly is soldering the connector board to the LCD itself. You must carefully line it up on both the LCD AND the shield board itself. More on that in a moment. To begin, […]

Embedded Tiny Basic: build apps for your projects

I, recently, embarked on building a useful if not glitzy digital clock. My first idea involved something retro: using four, seven segment, LED’s to look like something from the late 1970’s. At the same time, I was also playing around with 8×8 LED Arrays, using the MAX7219 chip. While playing with that, I connected one of my […]

Build your own ATtiny85 programmer using an UNO

As part of my ATTiny 85 learning adventure, I had to create some way to actually load code on to the 85 itself. My first go ’round was a breadboard monster. The thing I hate about bread boarding are the bloody wires. What a mess. Once I got my game working, I set out for […]
