Train Driver Module Software


The Train Driver nRF52832 microcontroller will run the FreeRTOS operating system, which is included with the Nordic nRF52 SDK. This is a small kernel with basic multitasking with queues, mutexes and so on. It is open source with a permissive license, as is the Nordic SDK that provides a BLE protocol stack and other functions.

The BLE stack runs in a closed source soft device through an API. This leaves a reasonable amount of bandwidth for running application logic.

Firmware Loading

During development firmware will be written to flash using an SWD programmer such as the Segger JLink.

In the field, updates will be loaded over the air using the Nordic DFU Service which is provided with the nRF52 SDK.
