\r
49 FreeRTOS training directly from Richard Barry, CEO of Real Time Engineers
\r
50 Ltd, and the world's leading authority on the world's leading RTOS.
\r

\r
54 compatible FAT file system, and our tiny thread aware UDP/IP stack.

59 http://www.OpenRTOS.com - Real Time Engineers ltd. license FreeRTOS to High

60 Integrity Systems ltd. to sell under the OpenRTOS brand. Low cost OpenRTOS
\r
61 licenses offer ticketed support, indemnification and commercial middleware.
\r
63 http://www.SafeRTOS.com - High Integrity Systems also provide a safety
\r
64 engineered and independently SIL3 certified version for use in safety and
\r
65 mission critical applications that require provable dependability.
\r
71 * "Reg test" tasks - These fill the registers with known values, then check
\r
72 * that each register maintains its expected value for the lifetime of the
\r
73 * task. Each task uses a different set of values. The reg test tasks execute
\r
74 * with a very low priority, so get preempted very frequently. A register
\r
75 * containing an unexpected value is indicative of an error in the context
\r
76 * switching mechanism.
