@ -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);`
