Add new instruction set for pcp4

Philipp Schindler — Thu, 21 Feb 2008 13:33:58 -0000

Add a new instruction set supporting the ad9910 board. And also the trigger counter.

Add counter for trigger inputs

Philipp Schindler — Thu, 21 Feb 2008 13:30:10 -0000

Add a counter to some of the trigger inputs. Also add an additional instruction for bracnhing depending on the counter value.

Phase registers

Philipp Schindler — Thu, 21 Feb 2008 13:27:48 -0000

Add phase registers to the firmware

UDP port numbers

Paul T. Pham — Fri, 05 Aug 2005 13:37:45 -0000

Because of the whole firewall port forwarding thing, we
need a range of 16 PTP server UDP ports corresponding
to 16 configurable MAC addresses and generated static
IP addresses. I have arbitrarily chosen these to be
0x2220 to 0x222F; however, this overlaps with the
current client port of 0x2221, causing any PTP clients
to receive back their own discovery requests, and in
general it is messy. So I propose moving the client
port to 0x221F.

MAC byte returned in discover reply.

Paul T. Pham — Fri, 05 Aug 2005 12:40:29 -0000

Add to the discover reply payload an extra byte
indicating the configurable MAC byte of the
sending/discovered device. Not all UDP implementations
allow passing up the sending UDP port (e.g. Python). We
need the sending UDP port to send replies back to for
proper firewall operation.

Minimum frame size limit

Paul T. Pham — Fri, 05 Aug 2005 12:38:35 -0000

Add to the protocol the minimum support frame size
limit, so that discovering new devices always succeed
no matter how limited the implementation.

External reset and trigger switch

Paul T. Pham — Fri, 05 Aug 2005 11:26:12 -0000

The sequencer should have dedicated external headers for
resetting and a manual trigger, which are tied to
ground with a
pull-down resistor and can be connected to
buttons/switches on
the faceplate.

Ground test loops.

Paul T. Pham — Mon, 20 Jun 2005 15:02:08 -0000

Add two vias to the ground plane for soldering a loop
of wire,
for clipping the ground of a scope probe.

Bus switch

Paul T. Pham — Mon, 20 Jun 2005 15:00:07 -0000

Replace the DIP20 bus switch part with the smaller, faster,
10-bit bus switch we already use on the sequencer hardware.

I2C breakout.

Paul T. Pham — Mon, 13 Jun 2005 11:20:33 -0000

It would be nice to breakout the I2C bus to a separate
3-pin
header (SDA, SCL, and ground) since there isn't enough room
on the 34-pin IDC headers. The I2C bus isn't very
useful if it's
just going to blink LEDs on the sequencer and breakout
boards.
