| Description of CMX-TINY+ - Scaled down version of the CMX RTOS |
Sales Enquiry |
|
|
|
The CMX-TINY+ Real-Time Multi-Tasking Operating System is now available for processors families such as Motorola 68HC08, Hitachi H8/300 & H8/300H & H8S, Atmel AVR family, Infineon (Siemens) 80C16x, Toshiba TLCS-900, NEC 78K0/K0S, TI MSP430, STMicroelectronics ST7 and others. The CMX-TINY+ provides slightly less functionality than the CMX-RTX RTOS. It was made to fit within the small amount of onboard RAM within the silicon, being in the range of 512 bytes and up.
The RTOS implements the following features:
- Control tasks
- Control events
- Control messages
- Control resources
- Control cyclic timers
- Interrupts allowed to signal tasks
- True preemption
- Cooperative scheduling allowed
- EXTREMELY Small RAM/ROM size
- Fast context switch times
- Low interrupt latency |

| CMXKAware |
Sales Enquiry |
|
|
|
| CMXKAware is an Active X object, DLL or ORTI (OSEK Run Time Interface) that presents all of the RTOS-specific information on the screen. CMXKAware allows you to display CMX-RTX's internal data structures in a convenient series of lists in the RTOS window of the debugger. This provides you with information about each of the active tasks in the target application, about each semaphore, resources, mailbox, queue and event flag group along with a list of all the tasks waiting on these kernel objects, and more. Data can be displayed graphically in real-time. |

| CMXBug |
Sales Enquiry |
|
|
|
| The CMX CMXBug debugger provides the user the ability to view and modify different aspects of the CMX multi-tasking operating system environment, while the user's application code is running. CMXBug runs as a task, usually being the highest priority task. In most cases, one of the target processor UART channel(s) is used as the input/output device. A simple terminal or CPU with a keyboard is all that is needed to use CMXBug. |

| CMXTracker |
Sales Enquiry |
|
|
|
| The CMX CMXTracker provides the user the ability to log chronologically in real-time, the tasks' execution flow, capturing when a task is executing, the CMX functions called and their parameters, interrupts using CMX functions and the CMX system TICK within the CMX-RTX real-time multitasking operating system environment, while the user's application code is running. Displaying of the log is performed by CMXTracker. which runs as a task, usually being the highest priority task. In most cases, one of the target processor UART channel(s) is used as the input/output device. A simple terminal or CPU with a keyboard is all that is required to use CMXTracker. |

| CMX-CANopen |
Sales Enquiry |
|
|
|
| CMX-CANopen allows for optimized implementations of CANopen conformant devices and was developed to allow for maximum task optimization, especially when used with an RTOS such as CMX-RTX. Even without an RTOS, CMX-CANopen allows for the adaptation of the execution priorities of critical tasks making CMX-CANopen one of the best performing CANopen stacks available. |
