)
This function tells the driver the location of one or two buffers for receiving data. You
need to allocate memory for the buffers before calling this function. If you do not need
two buffers, because you are not using aggregate mode, then you can optionally use
ps3000aSetDataBuffer instead.
Block and streaming modes with aggregation.
handle, the handle of the required device.
channel, the channel for which you want to set the buffers. Use
one of these constants:
PS3000A_CHANNEL_A
PS3000A_CHANNEL_B
PS3000A_CHANNEL_C
PS3000A_CHANNEL_D
To set the buffer for a digital port, use one of these values:
PS3000A_DIGITAL_PORT0 = 0x80
PS3000A_DIGITAL_PORT1 = 0x81
* bufferMax, a buffer to receive the maximum data values in
aggregation mode, or the non-aggregated values otherwise.
* bufferMin, a buffer to receive the minimum aggregated data
values. Not used in other downsampling modes.
bufferLth, the size of the bufferMax and bufferMin arrays.
segmentIndex, the number of the memory segment to be used
