A tiny “AT” (modem/communications) command parser #Communications #VintageComputing
The AT/Hayes communications command set has been in use since the Hayes 300 modem in 1981. It’s a set of commands sent to a controller, setting parameters for communications. Being ubiquitous, it helps not to have to learn yet another set of commands for a new piece of hardware.
Espressif microcontrollers have used them to access wireless communications.
The protocol is also in demand for emulating old modems on vintage computers to connect to bulletin boards (BBS) and to the internet.
Implementing the command set would be rather tedious at this point but it’s been done for you.
The Winkel ICT Tiny AT Command Parser is a zero RAM usage Hayes AT Command parser (GSM/Bluetooth) by using only pointers for parsing char arrays, fast, thoroughly tested.
When having to parse many GSM and/or Bluetooth commands on a low (flash/ram) memory budget this library can help out by keeping the in memory char array’s to an absolute minimum.
It is on GitHub under a GNU General Public License, v3.0.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
