It can be connected to most digital interfaces without additional active or passive components, and includes extensive protection from unexpected conditions and operator error. + +The Glasgow hardware can support many digital interfaces because it uses reconfigurable logic.

The interface logic that runs on the FPGA is described using `Amaranth`_, which is a Python-based domain specific language. The supporting code that runs on the host PC is written in Python with `asyncio`_. This way, the logic on the FPGA can be assembled on demand for any requested configuration, keeping it as fast and compact as possible, and code can be shared between gateware and software, removing the need to add error-prone "glue" boilerplate. + +Glasgow would not be possible without the `open-source iCE40 FPGA toolchain `__, which is not only very reliable but also extremely fast. It is so fast that it usually only takes a few seconds to build a bitstream from scratch for something like a UART. When developing a new applet it is rarely necessary to wait for the toolchain to finish. + +Implementing reliable, high-performance USB communication is not trivial—packetization, buffering, and USB quirks add up. Glasgow abstracts away USB: on the FPGA, the applet gateware writes to or reads from a FIFO, and on the host, applet software writes to or reads from a socket-like interface. Idiomatic Python code can communicate at maximum USB 2 bulk bandwidth on a modern PC without additional effort. Moreover, when a future Glasgow revision adds Ethernet next to USB, no changes to applet code will be necessary. + +Debugging applets can be hard, especially if bidirectional communication over the same wires is involved. Glasgow provides a built-in cycle-accurate logic analyzer that can relate the I/O pin level and direction changes to commands and responses received and sent by the applet. The logic analyzer compresses waveforms and can pause the applet if its buffer is about to overflow. + +.. _Python 3: https://www.python.org/ +.. _Amaranth: https://github.com/amaranth-lang/amaranth/ +.. _asyncio: https://docs.python.org/3/library/asyncio.html +.. _icestorm: https://github.com/YosysHQ/icestorm \ No newline at end of file diff --git a/latest/_sources/license.rst.txt b/latest/_sources/license.rst.txt new file mode 100644 index 000000000..895f8da72 --- /dev/null +++ b/latest/_sources/license.rst.txt @@ -0,0 +1,20 @@ +License +======= + +The Glasgow Interface Explorer source code, documentation, and design files are distributed under a choice of two licenses: 0-clause BSD and Apache 2.0. + +Catherine "whitequark", who has started the project, opposes copyright on moral and philosophical grounds, and the choice of the 0-clause BSD license reflects that.

You are provided with an async-capable environment, so no additional work is required on your part --- just use the ``await`` keyword... if you ever see a ````, try using ``await``. + + +How do I use this interface? +---------------------------- + +The exact usage will depend heavily on the applet you've requested, some examples are provided below, but please also have a look in the `examples `_ directory. + +As the startup prompt suggests, investigating ``help(iface)`` and ``help(device)`` are good places to start... after that, have a look at the applet's code. + +I²C +~~~ + +For this example, I will be using the `Sparkfun BMP085 `_ (a now-retired breakout for an I²C barometric pressure sensor), which supports 3.3v operation. + +.. note:: + I²C busses are implemented using open-drain, meaning that pull-up resistors are `required`... Glasgow's onboard 10kΩ pull-ups can be enabled by passing the ``--pulls`` argument, though they may not suffice for fast or long busses. This particular breakout board has on-board pull-ups already, so it's not necessary. + +.. code:: console + + $ glasgow repl i2c-initiator -V 3.3 + I: g.device.hardware: device already has bitstream ID f030465844b160e664799138b54ee2c7 + I: g.cli: running handler for applet 'i2c-initiator' + I: g.applet.interface.i2c_initiator: port(s) A, B voltage set to 3.3 V + I: g.applet.interface.i2c_initiator: dropping to REPL; use 'help(iface)' to see available APIs + >>> + +Let's start with a bus scan: + +.. code:: console + + >>> await iface.scan() + {119} + >>> + +Address``119`` has responded, which is ``0x77`` --- and this matches the datasheet! + +This sensor isn't the easiest to operate directly (you need to read a bunch of calibration and perform long calculations), so this is a great example of when you might want to start writing a script instead of using the REPL interface... however, to prove the point, we're going to read a register and leave the rest as an exercise for the reader. + +If you're familiar with I²C, you'll know that the typical convention is that the first portion of a write's payload will indicate the register to access, and a subsequent read will access the data from that location.
