arachnidlabs/loki

A versatile, extensible development system based on the Cypress PSoC line of processors.

Loki

Loki is a flexible development platform based on Cypress's PSoC 5 line of processors.

loki's Issues

Handle errors in asynchronous EEPROM operations correctly

When reading or writing the eeprom fails, record and report the status code correctly.

Put up basic documentation for starter planks

Each of the starter planks needs a basic page describing its functionality and pinouts.

Investigate a dedicated VID/PID for the Loki bootloader

Currently the Loki bootloader uses the default Cypress VID/PID. We need to investigate if we can use this, or if we need to obtain our own.

Write 'snake' demo app for the display plank

No nokia LCD is complete without Snake.

Add Arachnid Labs logo to Loki and planks

The Arachnid Labs logo needs to be added to Loki and each of the planks.

Port the Loki Plank TRM to arachnidlabs.com

The Loki Plank TRM needs porting to an arachnidlabs page, and updating.

Cause programmer treeview to be updated

When the name of a plank is changed, the treeview does not reflect the change.

Document the Display Plank library

The Display Plank / LCD library component needs documentation, both on the wiki and as a datasheet PDF attached to the component.

Implement drawing library for the display plank

The display plank now has a driver that supports framebuffers, but it needs a basic drawing library to be generally useful. Absolute minimum features would include:

• Drawing lines/boxes (filled and unfilled) and other simple shapes
• Displaying simple text in a single monospace font face

Possibly we can port or at least take inspiration from Adafruit's library here: https://github.com/adafruit/Adafruit-GFX-Library

The glcdfont in that library will definitely be useful as a basic and lightweight 5x7 bitmap font.

We also need to consider if it's worth supporting both vertical and horizontal addressing in the library, or if we should hardcode it to work with only one.

Add support for loading and saving EEPROM contents to disk.

Put up basic documentation for Loki

arachnidlabs.com needs a basic documentation page for Loki with some overall details, and other pages with tech specs, etc.

Add IO direction flags in plank configuration EEPROM layout

Add pin names to Loki silkscreen

Currently the Loki power/special IO header has no silkscreen labels; it needs some.

Write getting started documentation

We need some good getting started documentation, to take people from first receiving the device up to their first running code on the Loki. This needs to include:

• Installing PSoC creator
• Installing the INF file for the Loki, if required
• Installing the bootloader host
• Compiling their first demo
• Flashing it to the Loki

Write a demo app for the motor driver plank

The motor driver plank needs a demo app.

Cleanup and document the game of life demo

The game of life demo app needs tidying up, better commenting, and some documentation for getting started.

Write a demo app for the audio plank

The audio plank needs a demo app.
