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

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