It turns out, the SIM5320a has a Lua virtual machine onboard which can execute your own applications directly on the chip! I’m working to see if I can simplify my hardware design on my project by eliminating a controller board (currently a Pi). Also, I noticed the SIM5320a has two I2C pins on it which may be available via the Lua libraries, but more of that in a later post. Currently, I’d like to show how I was able to upload HelloWorld.lua to the Fona and execute it. For reference, my SIM5320a breakout board is connected to a Pi Zero, which I am accessing via my Mac and ssh. (I should post that set up, too, which was a bear, a lot harder than for a Pi2 or Pi3…)
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
