tone_cap_start
bool tone_cap_start(uint8_t pin)
Claim a state machine and a DMA channel, load the program, start the capture on pin.
Definition tone_cap.c:53

tone_cap_ring
const uint32_t * tone_cap_ring(void)
The ring.
Definition tone_cap.c:146

tone_cap_running
bool tone_cap_running(void)
Whether the capture runs.
Definition tone_cap.c:136

tone_cap_resume
void tone_cap_resume(void)
Mark a paused capture running again, when core 1 did not acknowledge the pause and nothing was taken ...
Definition tone_cap.c:114

tone_cap_stop
void tone_cap_stop(void)
Stop the capture and give back what it claimed; the pin is left an input with its pull-down on.
Definition tone_cap.c:119

tone_cap_pause
bool tone_cap_pause(void)
Mark the capture not running, so the next order tells core 1 to read nothing from it; the state machi...
Definition tone_cap.c:107

tone_cap_start_us
uint64_t tone_cap_start_us(void)
The microsecond timer when the counter began.
Definition tone_cap.c:141

tone_cap_wr
uint32_t tone_cap_wr(void)
The slot the DMA writes next; 0 when the capture does not run.
Definition tone_cap.c:151

tone_cap_rest
void tone_cap_rest(uint8_t pin)
The pin as an input with its pull-down on, driven by nothing: a tap that is off.
Definition tone_cap.c:43

tone_cap_stalled
bool tone_cap_stalled(void)
Whether the state machine dropped a word (its FIFO was full) since the last call; clears the flag.
Definition tone_cap.c:163
