For LPC176X (LPC1768/LPC1769) the flash driver has been implemented according to the CMSIS-PACK Keil.LPC1700_DFP.2.3.0 driver with the following changes in FlashPrg.c:
1. EraseChip() function removed (not used by flash_api)
2. Clock reconfiguration removed and clock value taken from function parameter to avoid unexpected behavior.

ARM mbed OS
mbed OS is an open-source embedded operating system designed for the "things" in the Internet of Things (IoT). mbed OS includes the features you need to develop a connected product using an ARM Cortex-M microcontroller.
mbed OS provides a platform that includes:
- Security foundations.
- Cloud management services.
- Drivers for sensors, I/O devices and connectivity.
mbed OS is modular, configurable software that you can customize it to your device and to reduce memory requirements by excluding unused software.
Release Notes
The Release Notes detail the current release and previous versions.
Continuous Integration Status
We run continuous integration on all of our branches and pull requests to verify the stability of mbed OS. The following are the Travis CI indicators for mbed OS.
- Master branch
- Latest release
Getting Started for Developers
You need mbed CLI to build mbed OS. For more details, read the mbed OS Handbook.
