46 * Initialize the specified channel of the ADC for AFSK needs.
47 * The adc should be configured to have a continuos stream of convertions.
48 * For every convertion there must be an ISR that read the sample
49 * and call afsk_adc_isr(), passing the context and the sample.
51 * \param ch channel to be used for AFSK demodulation.
52 * \param ctx AFSK context (\see Afsk). This parameter must be saved and
53 * passed back to afsk_adc_isr() for every convertion.

62 * Initialize the specified channel of the DAC for AFSK needs.
63 * The DAC has to be configured in order to call an ISR for every sample sent.
64 * The DAC doesn't have to start the IRQ immediatly but have to wait
65 * the AFSK driver to call AFSK_DAC_IRQ_START().
66 * The ISR must then call afsk_dac_isr() passing the AFSK context.
67 * \param ch DAC channel to be used for AFSK modulation.
68 * \param ctx AFSK context (\see Afsk). This parameter must be saved and
69 * passed back to afsk_dac_isr() for every convertion.
