Discussion Overview
The discussion revolves around the feasibility of using a Morse code timer integrated circuit (IC) for an intercom system. Participants explore various methods to implement Morse code signaling, including the use of microcontrollers and traditional timer circuits.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about the existence of a dedicated Morse code IC timer, suggesting that cascading 555 timers might be overly complicated.
- Another participant proposes using a PC to poll a port pin for high voltage states to count Morse code signals, indicating that this method could be straightforward if the operating system allows direct port access.
- A suggestion is made to utilize a PICAXE microcontroller as a potential solution for the project.
- A later reply expresses approval of the PICAXE option, noting the need for the electronics to be housed within the intercom and considering power options from the intercom or a small battery.
Areas of Agreement / Disagreement
Participants express varying opinions on the best approach to implement the Morse code timer, with no consensus reached on a single solution. Multiple methods, including microcontrollers and traditional timer circuits, are discussed.
Contextual Notes
Some limitations include the dependency on specific hardware capabilities, such as the ability of the PC/OS to access port pins directly, and the need for the electronics to fit within the intercom housing.
