Robert Jördens	56074cfffa	suservo: support operating with one urukul ... implemented by wiring up the second Urukul to dummy pins Signed-off-by: Robert Jördens <rj@quartiq.de>	2019-12-02 11:30:20 +01:00
Robert Jördens	74c0b4452b	suservo: clkout and sdo[b-d] are inverted	2018-05-14 12:26:49 +00:00
Robert Jördens	307cd07b9d	suservo: lots of gateware/ runtime changes ... tested/validated: * servo enable/disable * dds interface, timing, io_update, mask_nu * channel control (en_out, en_iir, profile) * profile configuration (coefficients, delays, offsets, channel) * adc timings and waveforms measured * asf state readback * adc readback individual changes below: suservo: correct rtio readback suservo: example, device_db [wip] suservo: change rtio channel layout suservo: mem ports in rio domain suservo: sck clocked from rio_phy suservo: cleanup, straighten out timing suservo: dds cs polarity suservo: simplify pipeline suservo: drop unused eem names suservo: decouple adc SR from IIR suservo: expand coredevice layer suservo: start the correct stage suservo: actually load ctrl suservo: refactor/tweak adc timing suservo: implement cpld and dds init	2018-04-27 13:50:26 +02:00
