Therefore, the +command line cannot block, else the timers + xbee rx won't be executed. + +A typical example where the command line blocks is the completion with +many choices. + +solution +-------- + +xbee rx and timers should be executed in a low prio scheduler +event. With this modification, the command line can block. However we +must prevent a xbee transmission to be interrupted by a task doing +another xbee transmission. For that, we will use scheduler_set_prio(). + +The problem with that is that we can loose precision for low prio +events if the scheduler interrupt occurs when the scheduler priority +is low. It could be fixed in scheduler, but maybe we don't need it. + +Priorities +---------- + +From highest to lowest priority. + +- Interrupts: + + - timer + - uart + - spi + - i2c + +- Events, called from timer interrupt after a call to sei(): + + - LED_PRIO: led blink + - BEEP_PRIO: process beep requests and modifies the beep_mask + - SPI_PRIO: send and receive SPI data to the atmega168p + - CS_PRIO: do the control system of the wing, reading infos from a + structure updated by i2c, and writing commands using + spi_set_servo() + - XBEE_PRIO: read pending chars on xbee serial line and process xbee commands, + send xbee commands. + - I2C_PRIO: send requests and read answers on i2c slaves + - CALLOUT_PRIO: calls low priority events using the callout + code.
