  • Page 7: Overview

    Programs are written on a PC compatible computer in the language of your choice. After your application has been compiled or assembled and linked into .EXE or .COM form, it is uploaded to the Flashlite's flash disk with your favorite telecommunications program using X-Modem protocol. The application can then be tested and debugged through the console serial port.

  • Page 8: Operation

    When an application is finished, either rename it to STARTUP, or create a batch file that calls the program. If the Flashlite is to be used as a stand- alone device without a console connection, avoid writing to the console.

  • Page 9: V-25 Internals - Ports/Registers/Interrupts

    Port (Px) register, the Port Mode (PMx) register, and the Port Mode Control (PMCx) register. These registers allow the port pins to be configured as inputs, outputs, or a special function. The following table shows the register addresses for each port. Flashlite User's Manual...

  • Page 16: Interrupts

    The 17 sources are divided into groups for management by the interrupt controller. Using software, each of the groups can be assigned a priority from 0 (highest) to 7 (lowest). The priority of individual interrupts within a group is fixed in hardware. Flashlite User's Manual...
  • Page 17 NMI, INTP0-INTP1 are edge-sensitive inputs. By selecting the appropriate bits in the interrupt mode register, these inputs can be programmed to be either rising or falling edge triggered. Bits ES0-ES2 correspond to INTP0- INTP2, respectively, as shown below: Flashlite User's Manual...

    BIOS Supported Functions The Flashlite Basic Input Output System supports the following software interrupts: Console Output Equipment Check Memory Size Disk Services Keyboard Driver Bootstrap V-25 Resources and the BIOS The BIOS uses the following V-25 ports, registers and register banks. The user should exercise extreme caution when using or modifying these resources.

  • Page 24: Utilities

    Utilities The Flashlite comes preloaded with several utilities to aid system develop- ment. These utilities are located on the A: drive of the Flashlite. UP.COM This utility facilitates uploading files to the Flashlite via the console port using the X-MODEM transfer protocol. The utility requires the user to supply the name of the incoming file.

  • Page 25: Micro-Basic

    MICRO-BASIC is a compact, full featured, BASIC language interpreter that allows immediate development and testing of small programs on the Flashlite. Most of the examples in this document written in BASIC will run in MICRO-BASIC. Due to its size, the list of supported commands and functions is smaller than some other common BASIC languages, but it does provide some functions only found in large development packages.

  • Page 26: Programming Examples

    QuickBASIC I/O Some of the code produced by Microsoft QuickBASIC and QuickBASIC Professional compilers does not execute properly on the Flashlite. In the case of console I/O, we believe that QuickBASIC is generating code for specific hardware and software not present on the Flashlite controller.
