Application Notes


Peripheral Driver Library

FM MCU Peripheral Driver Library (PDL)

The FM MCU Peripheral Driver Library (PDL) simplifies software development for the FM0+, FM3, and FM4 MCU families. The PDL reduces the need to understand register usage and bit structures, thus easing software development for the extensive set of peripherals in the FM families. You configure the library for the particular device, and then use API calls to initialize and use a peripheral. Using the PDL makes it easier to port code from one family to the other, because the same code supports all FM families.

The Sample Programs ("Programs") are offered for use in developing systems for Cypress microcontrollers.

The Programs will be useful in the following situations:

  • I need a simple sample program, as I am going to develop software. The sequence of resource access, among others, can be confirmed using these Programs.
  • I would like to examine, before development, whether each resource will operate as expected.
    The Programs support several specifications, even for the operation of one resource.
  • If resources do not operate properly on my system, I would like software for which confirmation of operation has been completed. Cypress has confirmed the actual operation of the Programs on each of its microcontrollers, so you will be able to compare your program with the Program.

For the FM portfolios, code examples are provided with the Peripheral Driver Library (PDL). Download and install the PDL, and look in the examples folder.
