\section { General Description}
The 2238 MCX-TTL card is a 4hp EEM module.
It adds general-purpose digital I/O capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
Each card provides four banks of four digital channels each, with MCX connectors, controlled through 2 EEM connectors.
Each EEM connector controls two banks independently.
Single EEM operation is possible.
The direction (input or output) of each bank can be selected using DIP switches.
Each channel supports 50\textOmega ~terminations individually controllable using DIP switches.
This card can achieve higher speed and lower jitter than the isolated 2118/2128 BNC/SMA-TTL cards.

\section { Example ARTIQ code}
The sections below demonstrate simple usage scenarios of the 2245 LVDS-TTL card with the ARTIQ control system.
They do not exhaustively demonstrate all the features of the ARTIQ system.
The full documentation for the ARTIQ software and gateware is available at \url { https://m-labs.hk} .
Timing accuracy in the examples below is well under 1 nanosecond thanks to the ARTIQ RTIO system.
\subsection { One pulse per second}
The channel should be configured as output in both the gateware and hardware.
\begin { minted} { python}
@kernel
def run(self):
self.core.reset()
while True:
self.ttl0.pulse(500*ms)
delay(500*ms)
\end { minted}
\subsection { Morse code}
This example demonstrates some basic algorithmic features of the ARTIQ-Python language.
\begin { minted} { python}
def prepare(self):
# As of ARTIQ-6, the ARTIQ compiler has limited string handling
# capabilities, so we pass a list of integers instead.
message = ".- .-. - .. --.-"
self.commands = [{ ".": 1, "-": 2, " ": 3} [c] for c in message]
@kernel
def run(self):
self.core.reset()
for cmd in self.commands:
if cmd == 1:
self.led.pulse(100*ms)
delay(100*ms)
if cmd == 2:
self.led.pulse(300*ms)
delay(100*ms)
if cmd == 3:
delay(700*ms)
\end { minted}
\newpage
\subsection { Counting rising edges in a 1ms window}
The channel should be configured as input in both the gateware and hardware.
\begin { minted} { python}
@kernel
def run(self):
self.core.reset()
gate_ end_ mu = self.ttl0.gate_ rising(1*ms)
counts = self.ttl0.count()
print(counts)
\end { minted}
This example code uses the software counter, which has a maximum count rate of approximately 1 million events per second.
If the gateware counter is enabled on the TTL channel, it can typically count up to 125 million events per second:
\begin { minted} { python}
@kernel
def run(self):
self.core.reset()
self.edgecounter0.gate_ rising(1*ms)
counts = self.edgecounter0.fetch_ count()
print(counts)
\end { minted}
\subsection { Responding to an external trigger}
One channel needs to be configured as input, and the other as output.
\begin { minted} { python}
@kernel
def run(self):
self.core.reset()
self.ttlin.gate_ rising(5*ms)
timestamp_ mu = self.ttlin.timestamp_ mu()
at_ mu(timestamp_ mu + self.core.seconds_ to_ mu(10*ms))
self.ttlout.pulse(1*us)
\end { minted}
\section { Ordering Information}
To order, please visit \url { https://m-labs.hk} and select the 2238 MCX-TTL in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url { mailto:sales@m-labs.hk} .
