Earle F. Philhower, III	0655b7d5b6	Fix ADCInput clocks for multiple inputs (#2755) ... When multiple inputs were active, the frequency was being scaled two times resulting in incorrect sampling speed. Correct to only scale the calculation and not the stored value (which is used in `begin`). Fixes #2754	2025-01-14 15:58:45 -08:00
Earle F. Philhower, III	690293e7e1	RP2350B additional ADC inputs for ADCInput (#2509) ... Fix pin offset and maximum count of ADC inputs for the RP2350B variant.	2024-10-01 18:22:11 -07:00
Earle F. Philhower, III	5b76b0668b	Addition ABM checks in PWMAudio and ADCInput (#1530) ... Handle the case where the DMA manager is unable to completely allocate needed resources (DMA channels or memory) and return `false` in ::begin()	2023-06-12 15:20:52 -07:00
Earle F. Philhower, III	da26016edf	DMA-based ADC input (microphone, analog sensor) (#1101) ... Mimics the I2S/PWMAudio/Stream interface for ease of use. * Fix non-32b DMA size transfer calculation in ABM * Rename wasHolding to isHolding in the I2S/PWM It is the **current** number of bits left, not the past number. * Add commented microphone example * Add docs	2023-01-05 16:00:34 -08:00
