* altos: No need to initialize EXTI priorities at startup timeKeith Packard2012-08-28
| | | | | | They all get set to the correct value when enabled. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Add ao_gpio_get and ao_exti_set_modeKeith Packard2012-08-06
| | | | | | Needed to support general GPIO interrupts Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Optimize FEC encode and decodeKeith Packard2012-06-26
| | | | | | | | | | | | | Integrate interleaving, CRC and padding within the decode/encode functions. Provide for ISR priorities so that the 1120 RX interrupt takes precedence over the other interrupts or we risk losing bits. Optimize the viterbi decoder a bit (goes from 10ms per packet to 7ms per packet). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Get cc1120 packet reception workingKeith Packard2012-06-25
| | | | | | Interrupt-per-bit, but it seems to work Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Fix broken EXTI edge mode selections. Clear pending exti on enableKeith Packard2012-06-02
| | | | | | | | | Make sure the edge mode registers are set according to the requested mode. Clear any pending interrupt when enabling to avoid spurious isr call Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Route correct GPIO line to interrupt controllerKeith Packard2012-06-02
| | | | | | | Which GPIO a particular pin interrupt comes from is selected by the SYSCFG EXTICR registers; set these when an exti interrupt is configured. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Starting to write cc1120 driverKeith Packard2012-04-17
This does "something" in radio test mode, appearing to generate a 730MHz signal. Signed-off-by: Keith Packard <keithp@keithp.com>
