Not hard, but a bit of thought is involved in handling Morse keying speed. Otherwise, the character must be developed individually from the raw elements. So, were one receiving ASCII from the serial port, your idea is grand. There is no carriage return and the speed is clocked by a human, not consistent. Morse comes in as dots/dits and dashes/dahs. So old, my cellphone camera only had 1 pixel:Īnd you have explained the hurdle. It was intended for outside, but cheap wireless came along before I built the solar power supply. I used the reversal to create a visual temperature project, the thermistor provided the temp and a LED flashed the Morse once a minute. The idea is really old, first implemented on PICAXE. Global variables use 290 bytes (14%) of dynamic memory, leaving 1758 bytes for local variables. Magic_Morse_V6.zip (5.9 KB) Sketch uses 6052 bytes (18%) of program storage space. I attached zip that compiles with most recent IDE 1.8.18 You can use a photo transistor in place of the physical Morse key: Where the LDR receives the signal from LASER and converts the morse code into original text and displays it into the 20*4 LED display? source listing, documentation, and comprehensive test fit on even the smallest of microcontrollers. requires only a few bytes of memory to operate, and will ![]() It typically compiles to under 200 bytes (table included), It accepts a dot ('.'), dash ('-'), or terminator (0) one .this deterministic state machine for decoding Morse ![]()
