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.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
