Nordic nRF51 & nRF52 product line
NOTE : This library is now replaced by https://github.com/IOsonata/IOsonata
This is a multi-archtecture multi-platform Hardware Abstraction Library. The main purpose is to create a layer of generic peripherals and devices interface (drivers) that is common across MCU architectures and platforms. This will allow creation of more reusable and portable applications (firmware for most part) that can be moved form on MCU to an other with minimal changes.
See https://embeddedsoftdev.blogspot.ca/p/h.html for more detail installation and setup of development environment.
Library online documentation located here https://www.i-syst.com/docs/EHAL/
Library source code on GitHub at https://github.com/I-SYST/EHAL
- Need to port a specific driver or MCU ? Put your request in issues. It will get done eventually. If you want to have it faster, a fee based port is available.
CMSIS : ARM CMSIS SDK for all ARM platform
nRF5_SDK : Nordic nRF5x Bluetooth Low Energy
nrf5_SDK_Mesh : Nordic nRF5 SDK for Bluetoth Mesh
Micro-ECC : Encryption library
ICM-20948 Motion_Driver : Create a user at https://www.invensense.com/developers. Under "Downloads" download "DK-20948 eMD-SmartMotion ...". Unzip the downloaded file and navigate to EMD-Core/sources. Copy the folder Invn to external/Invn as indected in the folder tree bellow.
KSDK : Kinetis SDK
BSEC : Bosch Sensortec Environmental Cluster (BSEC) Software for #BME680 environmental sensor. BSEC is needed for calculating Air Quality Index. Go to https://www.bosch-sensortec.com/bst/products/all_products/bsec at the end of the page. Select checkbox to accept license terms to download. Unzip the the downloaded file. Rename the extracted folder BSEC and copy the whole folder to external as indicated in the folder tree bellow.
The way the EHAL folder is structure is simple. The deeper you go inside the more it is specific the the architecture or platform. The parent folder contains all that is commonly available to the child folder. Which means, source file from child folder can access any source in the upper parent folder but not the other way around. This is the way to keep the abstraction separated from implementation and easier to keep track of things.
There are 2 main libraries in the EHAL for each ARM based MCU.
- CMSIS : This contains the startup code, main interrupt vector and RTOS if available. This lib is required for all firmware
- EHAL : This is the main hardware abstraction library. It contains all peripheral drivers, SPI, I2C, UART, Timer, BLE,...
