Our best offer to you is Quality, Tested and Reusable code.

Reuse our fully defined, well-tested, documented software and drivers, OSAL, HAL & BSP package for 8/32-bit MCUs.

Board Support Package (BSP)

Every BSP implementation regardless MCU use exact Hardware Abstraction Layer (HAL) interface. This abstraction helps for seamless migration from one MCU to another without affecting other software components.

Board Support Package (BSP) help to speed up the board creation process. In each BSP, we try to implement all peripherals available on the MCU with highly dynamic configuration and expose all available peripheral channels. This BSP can be used both with and without RTOS, with some BSPs having an API to lock the resources when used under RTOS.
 

This BSP is the realization of our generic HAL API, which has now existed for 4 years without major changes and is used on 3 different platforms such as the Microchip PIC32 series and the NXP LPC series. This BSP is also used in our device driver implementation so that our driver is platform and operating system independent. The BSP design is simplified yet dynamic enough to support any peripheral function while maintaining the genericity of the interface.

Our list of available BSPs may not be very long and covers a variety of MCUs with different architectures, but based on our experience, you only need a small selection of MCUs, but with stable, well-tested and highly configurable BSPs and HAL interfaces that can be safely used with RTOS. Each BSP is supplied with a sample program in bare metal and RTOS as well as a software design document for evaluation purposes.

OS Abstraction Layer (OSAL)

OSAL implementation for future supported RTOS such as ThreadX will use exact generic OS Abstraction Layer interface that being used for FreeRTOS. This abstraction makes it possible to migrate from one RTOS to another without affecting other software components.

FreeRTOS

FreeRTOS may be an old but golden RTOS. In short, it is a scheduler that allocates time for each task to execute its program. This RTOS is easy to adopt, has a low learning curve and can be ported to new MCUs that are not yet supported. Nevertheless, this RTOS has proven itself and is used by companies such as Dyson, Bosch and Philips in their product lines.
 
SAFERTOS with the same interface as FreeRTOS is available if your application software needs to be certified according to ISO 26262, IEC 61508 SIL 3 and DO-178C.
