Hacking Digital Calipers with CircuitPython #CircuitPython #Hacking @jorgegarciadev @Microchipmakes
Via Jorge Garcia – the SAM32 dev board is amazing, squeezing in a Microchip SAMD51, an ESP32, and an microSD card onto an Adafruit Feather sized PCB, making it plug compatible with dozens of add-on boards.
It’s tedious to write down digital caliper measurements while working with research samples since you have to set the calipers down each time to record the value.
The solution: Use a SAM32 to read the caliper measurement, decode the protocol, and emulate keystrokes over USB to enter data into spreadsheet. Note: the user specifically wanted the calipers to be wired
The post goes through the process of looking for a compatible tool and interfacing. All the code necessary is then presented with the interface coded in CircuitPython.
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.
