Can DAC228_T0_CH3 be used?

HI there,

I find out that for the 7DDAC channels of QICK, you are using 3 DACs of DAC228_T0 (CH0, CH1, CH2), while leaving CH3 not connected? Why is this? Can this channel be connected? Thanks!

With the current architecture, the maximum number of DAC outputs from the tProcessor is 7 - see also #156.

If you want to disconnect some other channel so you can use this one, you would need to modify and recompile the firmware.

thanks!
