Differences

Differences lists the differences to be considered when migrating from RL-ARM to MDK-Professional.

  • The Middleware Components RL-FlashFS and RL-USB are provided as libraries. No source code is included.
  • The RL-FlashFS and RL-USB API functions can be used across supported devices.
  • RL-USB supports USB Devices and USB Hosts.

RL-FlashFS Details

  • Multiple FAT drives can be operated at the same time.
  • The Flash File System allows multiple instances of the same driver.
  • The file File_Config.c has been rewritten and contains macro definitions and no code.
  • The function finit() accepts an argument to initialize one or all drives.
  • The function funinit() has been added to shutdown a volume.
  • The IOC interface has been added to handle read/write operations on FAT media. The related functions start with ioc_.

RL-USB Details

  • Software abstraction layers have been added to handle the USB Device specific communication.
  • USB settings are done in a common file usb_config.c using the µVision Configuration Wizard.
  • Descriptors and Endpoints are created automatically based on the configuration settings in usb_config.c.
  • User code should be added into the file usbd_user_class.c.
  • The device initialization code should be added to the function usbd_class_init() located in the file usbd_user_class.c.
  • Device specific library functions start with usbd_.
  • Host specific library functions start with usbh_.
