This Concept Map, created with IHMC CmapTools, has information related to: TachyonBased_P1_CW_keyerForHighSpeedMorseCodePractice, Main goals are: 2. Minimal but adequate feature set - this means, take the dual paddle or a single lever key as input allow for the manual speed control with basic but proper timing of the Morse code characters, preferably by means of the quadrature encoder or up/down buttons, take the dual paddle or a single lever key as input TachyonBased_P1_CW_keyer_FirstBullet, Minimal but adequate feature set - this means it must: take the dual paddle or a single lever key as input, allow for the manual speed control with basic but proper timing of the Morse code characters, preferably by means of the quadrature encoder or up/down buttons allow for saving the parameters on power off and automatically restoring them on power on produce sound, which frequency can be user determined to be between 300Hz and 800Hz, when the key contacts are closed - I hate the sound of the square wave but that's what I'll start with provide visual indication for dits and dahs consume as low power as only possible while retaining all of the above features - the plan is to have it battery operated in the field, Main goals are: 1. Use whatever P1 hardware one has available - this means it must run on a minimum P1 hardware. I will use my home made P1 "ugly" board., allow for saving the parameters on power off and automatically restoring them on power on produce sound, which frequency can be user determined to be between 300Hz and 800Hz, when the key contacts are closed - I hate the sound of the square wave but that's what I'll start with provide visual indication for dits and dahs consume as low power as only possible while retaining all of the above features - the plan is to have it battery operated in the field Future proof - it must allow for easy addition and customizations of features but still be able to operate on the same hardware and Tachyon platforms as it's core - this means new features must not require any changes to the core hardware (the minimum P1 hardware I start with) but hardware expansion is allowed if necessary. Open source - based on the open schematics and software. Move to the new features only if, and when, these basic ones are realized and proven to be working flawlessly.
