Function Documentation

Debug_Dump()

uint32_t Debug_Dump

(

uint32_t

data

)

Debugging dump.

Records one data and one time into the two arrays.

Parameters

data	is value to store in DataBuffer

Returns

1 for success, 0 for failure (buffers full)

Note

Initializes your index or pointer

Debug_Init() Debug_Period()

Debug_Dump2()

uint32_t Debug_Dump2

(

uint32_t

data

)

Debugging dump with filter.

One first call record data and time. On subsequent calls, only record data and one time only if the data differs from the last recording

Parameters

data	is value to store in DataBuffer

Returns

1 for success, 0 for failure (buffers full)

Note

Initializes your index or pointer

Debug_Init() Debug_Period()

Debug_Duty()

uint32_t Debug_Duty

(

uint32_t

mask

)

Initialize arrays.

Calculate duty cycle of the recorded data using mask.
Period is defined as rising edge (low to high) to the next rising edge.
High is defined as rising edge (low to high) to the next falling edge.
Duty cycle is (100*High)/Period

Parameters

mask	specifies which bit(s) to observe

Returns

period in bus cycles, 0 if there is not enough collected data to calculate period

Debug_Period()

uint32_t Debug_Period

(

mask

)

Initialize arrays.

Calculate period of the recorded data using mask

Parameters

mask	specifies which bit(s) to observe

Returns

period in bus cycles, 0 if there is not enough collected data to calculate period

Note

Period is defined as rising edge (low to high) to the next rising edge

Sends one 8-bit data to PC at 10kHz

Parameters

adc12	is ADC0 or ADC1 (set to 0 for logic analyzer)
channel	specifies ADC channel 0 to 7
logic	function that returns an 8-bit value with bit 7 set

Returns

none
