What's New in ARTX-ARM

The following sections list the changes instituted in each release of the ARTX-ARM Advanced Real-Time Kernel.

ARTX Version 1.10 Release

• [Kernel]
  Added the os_evt_get event handling function which returns event flags served by the os_evt_wait_or function.
• [Kernel]
  Added the following examples to the \KEIL\ARM\ARTX\EXAMPLES\ base folder:
  • RoundRobin demonstrates round-robin task switching.
  • Semaphore demonstrates how to use a shared resource (a UART) from different tasks using a semaphore.
• [Kernel]
  Corrected a configuration problem of the timer tick reload in the ARTX_CONFIG.C configuration file for OKI and ST devices. Improper timer tick reload could cause stalls in Kernel delay handling when isr_mbx_send, isr_evt_set, and isr_sem_send functions were used.
• [Kernel]
  Corrected a problem with invalid delays when frequent isr... function calls were made from interrupt routines. This could cause shorter delays than specified for os_dly_wait, os_itv_wait, and other system delay and timeout functions.
• [Kernel]
  Corrected a problem in os_mbx_wait and os_sem_wait functions when they were called with the timeout parameter set to 0. In this case the function returned a wrong result value. The timeout value 0 is used to fetch a message or obtain a token from a semaphore without waiting.
• [Kernel]
  Modified the ARTX_CONFIG.C configuration files for all device variants. The function os_tmr_set_ovf has been replaced with by the os_tmr_force_irq function.
  
  The ARTX_CONFIG.c has been updated and is no longer compatible with older versions.
• [TCPnet]
  Corrected a problem in the Telnet server when some characters were not echoed back. This problem occurred if typing on the remote Telnet client was too fast.
• [TCPnet]
  Corrected a problem of locking-up an LAN91C111 Ethernet controller on high traffic LANs. This problem could occur when a lot of packets are received in a short time and the CPU is not fast enough to process them. When the MMU unit of the LAN91C111 Ethernet controller is locked, the driver now restarts the MMU unit to prevent lockups.
• [TCPnet]
  Added configurable PPP retransmissions and timeouts to the ANET_CONFIG.C configuration file. You may increase the default timeouts and number of retransmissions when PPP connections fail on slow serial links or when network latency is high (as may be the case with a GSM PPP data link).
• [TCPnet]
  Added new functions http_get_info and tnet_get_info to retrieve the remote machine IP address and MAC address. These functions may be used to limit access rights from remote machines based on IP or MAC addresses.
• [TCPnet]
  Added a serial driver for Philips LPC21xx devices. This driver is used for serial PPP or SLIP connections. The following serial drivers are currently available:
  • \KEIL\ARM\ARTX\SRC\TCPNET\SERIAL.C for Philips LPC21xx and LPC22xx devices.
  • \KEIL\ARM\ARTX\SRC\TCPNET\SERIAL_S3C44B0X.C for Samsung S3C44B0X devices.
  
  The ARTX_CONFIG.C has been updated and is no longer compatible with older versions.

ARTX Version 1.02 Release

• [Kernel]
  Added ARTX_CONFIG.C configuration files for OKI devices. See \KEIL\ARM\STARTUP\OKI\ARTX_CONF_ML67.C for OKI ML67xxx devices.

ARTX-ARM Version 1.01 Release

• [ARTX-ARM]
  Added example projects for the following target hardware:
  • Analog Devices ADuC702x Evaluation Board (\KEIL\ARM\BOARDS\ADI\ADUC702X\ARTX_BLINKY) For Analog Devices ADuC702x Devices
  • Atmel AT91SAM7S Microcontroller Board (\KEIL\ARM\BOARDS\ATMEL\AT91SAM7S\ARTX_BLINKY) For Atmel AT91SAM7S Devices
  • Hitex STR7 Evaluation Board (\KEIL\ARM\BOARDS\HITEX\STR7\ARTX_BLINKY) For STMicroelectronics STR71x Devices
  • Keil MCB2100/2130 Evaluation Board (\KEIL\ARM\ARTX\EXAMPLES\BLINKY) For Philips LPC21xx Devices
  • STMicroelectronics STR7 Evaluation Board (\KEIL\ARM\BOARDS\ST\STR7\ARTX_BLINKY) For STMicroelectronics STR71x Devices
• [Kernel]
  Added device-specific configuration files for the following:
  • Analog Devices ADuC702x (\KEIL\ARM\STARTUP\ADI\ARTX_CONF_ADUC702X.C)
  • Atmel AT91SAM7Sxx (\KEIL\ARM\STARTUP\ATMEL\ARTX_CONF_SAM7S.C)
  • Philips LPC21xx and LPC22xx (\KEIL\ARM\STARTUP\PHILIPS\ARTX_CONFIG.C)
  • STMicroelectronics STR71x (\KEIL\ARM\STARTUP\ST\ARTX_CONF_STR71X.C)
• [Kernel]
  Modified the ARM-Specific Software Interrupt Handler (in SWI_ARTX.S) to make it generic for all ARM devices. Some devices may require a NOP instruction to avoid Data Abort traps between stack switching.
• [Kernel]
  Enhanced the Stack Load display in the µVision Advanced RTX Dialog (available from the Peripherals Menu while debugging). Stack details are no updated from the current stack pointer value.

ARTX-ARM Version 1.00a Release

• [Kernel]
  Added the os_tsk_create_ex and os_tsk_create_user_ex functions. These routines make it possible to pass a parameter to a task when it is created. This is useful when creating multiple instances of a single task.
• [Kernel]
  Added the os_tsk_prio function which allows a task to change the priority of other tasks in the system.
• [Kernel]
  Added the os_tsk_prio_self routine which allows a task to change its own priority.
• [Kernel]
  The ARTX_CONFIG.C configuration file has been updated. Applications using the previous configuration file must be updated with the new configuration file.

ARTX-ARM Version 1.00 Release

• [Kernel]
  Optimized and updated the task switch function.
• [Kernel]
  Updated the ARTX_CONFIG.C configuration file to support the µVision debug dialog.
• [Kernel]
  Updated documentation and added context-sensitive help within µVision.
• [Kernel]
  Updated examples to run on the MCB2100 and MCB2130 Evaluation Boards.
