New examples included in v7.0 Astrobe for RISC5

[cfbsoftware]

The following examples are now included in source and executable form in the standard distribution of v7.0 Astrobe for RISC5:

• Blinker:
  Flash up to ten LEDs in a sequence at 1 second intervals.
• ButtonTest
  Run - Loops infinitely. When a button is pressed the button number is displayed and the program terminates.
• DRAMTest:
  Run - Execute six different tests to identify faulty 4164 64kbit DRAM chips.
• Extensions, ExtensionsCase and ExtensionsProc:
  Run - Three different ways to use Oberon's Type Extension feature to create and scan a dynamic list of a variety of objects.
• HCReadSpeed
  Run - Time the sector reading speed of an HCFiler filesystem on the SDHC Card.
• HCTest
  Run - Inititialise an HCFiler filesystem and create a number of test files on the SDHC Card. Any existing HCFiler files will subsequently be inaccessible.
• HCTools:
  InitDisk - Initialise an HCFiler filesystem on an SDHC card. Any existing HCFiler files will subsequently be inaccessible.
  WriteFiles - Copy files from a Project Oberon filesystem to an HCFiler filesystem on the same SDHC card
  Dir - Display a list of HCFiler files on the SDHC Card.
• I2CCompass:
  Show - Display the reading from a Honeywell HMC6352 digital compass.
• I2CTemperature:
  Show - Display the temperature read from a Texas Instruments TMP102 digital temperature sensor.
• Soundex:
  Run - Compare the performance of numeric CASE statements vs. the equivalent IF-THEN-ELSE statements.
• SwitchTest
  Run - Displays a list of switches that are on.
• Temperature:
  Show - Display the temperature read from a DS3234 Real-Time Clock peripheral device.
• TestInt:
  On - Enables interrupts. An interrupt handler is installed when the module is loaded. When interrupts are enabled the handler is invoked every 500 ms to blink an LED.
  Off - Disables interrupts. The LED stops blinking.
