Lisp Badge LE Development Board [Copy link]

 

This is a self-contained, low-power computer with its own display and keyboard that can be programmed using uLisp, a version of the high-level language Lisp for microcontrollers.

It is based on the AVR128DB16 with 128K bytes of flash and 48K bytes of RAM. There is an integrated 45-key keyboard optimized for Lisp, using reverse-mounted buttons to provide space for large key legends on the PCB.

It features a low power monochrome display that is readable in daylight without the need for a backlight, so is perfect for programming in the garden or on the beach! This will provide graphics with 10 lines of 41 characters or a resolution of 250×122 pixels, supported by several graphics commands.

You can use it to run programs that connect to components such as LEDs and buttons through I/O pins, read analog inputs, and operate external devices through I2C and SPI interfaces.

It runs at about 6mA and can operate for about 40 hours using a CR2032 battery.

I'm here to complain again. This button is so uncomfortable.

The power consumption is only 6ma, which is amazing.

The buttons are indeed too small and hard to press. This is how foreigners design it. It is still most convenient to operate it remotely or through a serial port.

The 2.54 pin on the right is a failure, the circuit power consumption is too high, the performance is too small. It is not as good as the Wenquxing more than 10 years ago.

It consumes about 6mA of power and can operate for about 40 hours using a CR2032 battery.

This is too powerful!

Shouldn't ARM dominate the market now? Why are there still people using AVR outside of China?

Only in China is ARM dominating the world
