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.
In the current project, the SAM32 is interfaced with some digital calipers:
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.
See the post for full details and code. Well done!
