2.5.5.12 Waveform Data Command

The BUF command allows to access the metrology samples being captured and processed. The metrology library must be previously configured through the control registers: CAPTURE_CTRL, CAPTURE_BUFFER_SIZE, and CAPTURE_ADDR (refer to the Microchip “PIC32CXMTx Metrology Data Sheet” and the Microchip “PIC32CXMTx Metrology User Guide” for additional information).

If the command is sent without a parameter, the Demo Meter Application returns all the data in the buffer. If the command includes a parameter (for example, BUF[2]), only a 512 sample set is returned. The parameter indicates the index of the set of samples (BUF[0] returns samples 0 to 511, BUF[1] returns samples 512 to 1023, and so on) .
