HexBot needs a new chip ... More RAM maybe even a Faster Clock!


Senior Member

Is it possible to program newer chips with the PICAXE Loader to have more memory for programs, a faster clock?

8K of flash RAM would be really nice for larger more complex programs like this HexBot I made;

20210717 HexBot+Maestro12 Test6

After converting the 3-color LEDs to just direct PIN high/low the program uses 4043Bytes. No room to control the gripper or the upper Pan&Tilt let alone any kind of device on the Pan&Tilt.

6K or more memory would let this robot become autonomus rather than IR remote control.

You can see the code on my website: RoboGuts™ PICAXE 28X2 Module (r2pv1.com)

From Manual 1:
Advanced: (2000 - 3200 line memory, per each of (up to) 4 separate slots)
28X2 22 configurable i/o 0-16 ADC 64MHz
40X2 33 configurable i/o 0-27 ADC 64MHZ

Additional slots of I2C memory can be used.
