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

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