@ -73,14 +73,14 @@ chMBPost(&led_mailbox, message, timeout);
|

|

An example:
|
||||
1. set the message to be sent. First byte (LSB) is the led address, and second is the message type
|
||||
*`msg=(ON_LED << 8) | 42;`
|
||||
* `msg=(ON_LED << 8) | 42;`
|
||||
2. send msg to the led mailbox
|
||||
*`chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
|
||||
* `chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
|
||||
|
||||
Another:
|
||||
*`msg=(BLINK_TOGGLE_LED << 8) | 46;`
|
||||
*`chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
|
||||
* `msg=(BLINK_TOGGLE_LED << 8) | 46;`
|
||||
* `chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
|
||||
|
||||
Finally, SET_FULL_ROW requires an extra byte with row information in the message so sending this message looks like:
|
||||
*`msg=(row<<16) | (SET_FULL_ROW << 8) | (led_pin_byte);`
|
||||
*`chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
|
||||
* `msg=(row<<16) | (SET_FULL_ROW << 8) | (led_pin_byte);`
|
||||
* `chMBPost(&led_mailbox, msg, TIME_IMMEDIATE);`
