For about 10 months now Colin Riley has set about the task of designing his own CPU using VHDL, “Because, I can! Why not? I’ll learn a load of stuff!”
I started writing in TPU assembly the various code areas I’d need to interface with ESP8266. They were mainly string operations over the UART – so, things like SendString, RecieveString, and ExpectString, where the function waits until it matches a string sequence received from the UART. The code and data strings needed for a very simple test is well over 1KB which was a lot of code for this. I created various test benches and the code eventually passed those tests in the simulator.
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.
