This post by Peter Scargill may prove useful to makers looking to free up programming space in their ESP8266 designs.
What you see above – the left 2 columns represent the very original code I used with TuanPM’s MQTT as the base. In the middle one I’d moved non-volatile storage up to the top of available FLASH space (which applies to most of the current crop of boards from ESP-01 upwards) and moved the start of code all the way down to 0x10000 giving a massive amount of room for development – unlike the original case where I was running out.
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.
