TIMER2_7_IRQ is shared among several timer sources, including us_ticker. Raising TIMER2_7_IRQ pending bit will trigger the timer interrupt, but the timer interrupt handler will not know which timer source this interrupt is for. This patch sets timer load value to one tick and force us_ticker to fire almost "immediately". TIMER2_7_IRQ is handled through a common interrupt handler, and is automatically cleared. Therefore, there is no need to clear IRQ. The underlying timer HAL treats load value as micro-seconds and does conversion internally. Therefore, simply pass micro-seconds to timer HAL without converting to tick first. Signed-off-by: Tony Wu <tung7970@gmail.com> |

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.
