Introduction A minimal Modis Lock system consists of a Host Controller that houses a Raspberry Pi Compute Module 3 and a Reader unit with an ARM microcontroller. The Host Controller is the ‘brain’ of digital access control and the reader unit receives remote inputs. Even though the Host Controller has a powerful quad-core BCM2837 Broadcom [...]

How to interface a Microcontroller with a Raspberry Pi through UART

By Richard Lowe|2018-09-04T10:01:56+02:0023/07/2017|Categories: Coding, Education|Tags: communication, education, M2M, MCU, python, RPI, UART|

The main engine of the Modis Lock host module is a Raspberry Pi Compute Module 3. The CM3 module also uses an ARM core microcontroller to facilitate reliable communication with its remote reader modules. Setting up an interface between a Raspberry Pi and a remote peripheral is pretty straight forward with the [...]
