Custom Peripheral Drivers¶
The mbed libraries allow for standardized, simplified usage of more peripherals. However there are also user libraries which allow for faster, more efficient and/or more flexible use of these peripherals. With the exception of the software emulators of peripherals, these libraries are generally limitted to a subset of the mbed supported boards, so you need to make sure yours is supported!
