35 * This version of comtest. c is for use on systems that have limited stack
36 * space and no display facilities. The complete version can be found in
37 * the Demo/Common/Full directory.
38 *
39 * Creates two tasks that operate on an interrupt driven serial port. A
40 * loopback connector should be used so that everything that is transmitted is
41 * also received. The serial port does not use any flow control. On a
42 * standard 9way 'D' connector pins two and three should be connected together.
43 *
44 * The first task posts a sequence of characters to the Tx queue, toggling an
45 * LED on each successful post. At the end of the sequence it sleeps for a
46 * pseudo-random period before resending the same sequence.
47 *
48 * The UART Tx end interrupt is enabled whenever data is available in the Tx
49 * queue. The Tx end ISR removes a single character from the Tx queue and
50 * passes it to the UART for transmission.
51 *
52 * The second task blocks on the Rx queue waiting for a character to become
53 * available. When the UART Rx end interrupt receives a character it places
54 * it in the Rx queue, waking the second task. The second task checks that the
55 * characters removed from the Rx queue form the same sequence as those posted
56 * to the Tx queue, and toggles an LED for each correct character.
57 *
58 * The receiving task is spawned with a higher priority than the transmitting
59 * task. The receiver will therefore wake every time a character is
60 * transmitted so neither the Tx or Rx queue should ever hold more than a few
61 * characters.
62 *

65 /*
66 Changes from V1.2.0:
67
68 + Reduced the maximum time between successive transmissions. This provides
69 for a more rigorous test.
70
71 Changes from V2.0.0
72
73 + Delay periods are now specified using variables and constants of
74 portTickType rather than unsigned portLONG.
75
76 Changes from V2.5.1
77
78 + The constant comOFFSET_TIME added to the delay period to ensure a more
79 random delay period is used.
