A user is asking about the compatibility of different modules (GPS, GPIO, I2C, 'Port C' UART) with the Cardputer, specifically whether modules using 'Port C' can be used.
An article discussing the use of HID over I2C for coupling STM32 and Linux in a project, offering a detailed example, and discussing the benefits such as compatibility, low power consumption, and ease of implementation.
Discusses HID over I2C, an underappreciated HID standard used in laptops. Explains that I2C-HID is used for touchpads, touchscreens, and sensor hubs. Distinguishes I2C-HID from non-HID I2C devices and explains its benefits. Describes the author's experience with using I2C-HID for a laptop touchpad project.
