Reference Software Development for SPI Stack Integration

Introduction: This case study highlights Spanidea’s expertise in designing and developing reference software for integrating SPI (Serial Peripheral Interface) stack with third-party vendors. The project involved the development of a SPI network driver, implementation of 3GPP TS 27.010 (LTE/3GPP), and PPP (Point-to-Point Protocol) implementation on top of the SPI network driver. The platform used was a dual MIPS core (MIPS 4kec) mobile router with embedded Linux on one core and an RTOS on the other core.
