Input from Serial Terminal

• Read strings and integers from a serial terminal.
• See Text Output and Input
• See modules
  • In (new),
  • Texts (extended: input procedures),
  • TextIO (extended: error codes, res parameter for reading),
  • UARTstr (extended: input procedures),
  • UARTkstr (extended: input procedures)

Modules UARTd, UARTstr, UARTkstr

• Added input procedures.
• Added functionality to enquire the device status/flags, for example for checking on the FIFO buffer state, in lieu of the traditional TxAvailable and RxAvailable.

Module Kernel

• Allocate CoreContext for a core in Kernel.Install, not in module initialisation.
• Added functionality to change a thread’s period and priority from “inside” a thread (in-thread API).
• Renamed Kernel.AwaitDeviceSet to Kernel.AwaitDeviceFlags, extending its functionality to check for device flags set or cleared, using two masks (see UARTkstr.mod for a use case).
• Extended the scheduler for Kernel.AwaitDeviceFlags.
• Added Kernel.StartTimeout (see UARTkstr.mod for a use case).
• Fixed a defect where a thread could be scheduled by time trigger while waiting for device flags.

Module MCU2

• Introduced register addresses M0PLUS_* as per the datasheet. It’s easier to discern the addresses that are core-specific, ie. not shared.
• Kept current definitions as aliases.
