GPIO needed for "enable" signals, i.e. camera module
Currently, the adapters are only present on the Hardware directory of the repo. Maybe it is interesting to have them listed on the doc website...
Eventually this would require to decide on what is publicly visible and what considered "internal intermediate state", only given to one client or two.
The datasheet became a deadlink, and now we have this https://www.diodes.com/assets/Datasheets/products_inactive_data/AP2120.pdf
The link is products_inactive_data
.
That does not look like a part difficult to source or extremely demanding in specs though...
Here is a discussion to start anticipating the role an ATtiny could have on such a module, for inclusion in Rev3 instead of the GPIO expander.
Some of the schematics need to be updated, currently a 404.
Currently, locating the connectors on the devboard is a bit challenging to figure out.
A photo with an overlay drawing could help, or something like this:

This seems to be required but not present on the doc for Ubuntu.
The quickstart section is out of date. This require users to go bug us to get started and is not pleasant.

Furthermore, there are no general instructions for how to plug things together, and what to connect, and what to expect, where to get the debug logs.
Things that are obvious after being introduced to it, and a short summary can help confirming what is expected.
I.e.:
/dev/ttyUSB#
interfaces, but only one of them (usually the second) is containing logsThe open-source command line tools used to debug the tinyCLUNX33 such as ecpprog
were developped under Linux as part of the Yosys community.
This means they use libusb
to implement the FTDI driver in user-space, rather than using the FTDI-provided driver (absent on Linux). One Windows, like for many command line utilities developped for Linux/MacOS first, this means that it is required to switch the driver used using tools like Zadig, so that instead of using the FTDI driver, they get a generic driver assigned allowing to communicate with the device directly.
Also, on Linux, in order to be able to read logs from the /dev/ttyUSB1
device, it is required to:
dialout
(I think?) groupAnd to be able to use ecpprog
command:
An alternative to bypass all of this setup is to run the command with sudo
And bit of background about how this can be done in a VM or WSL would also be appreciated: links for how to access a local USB device into WSL or in a VM, even if it is not tested.
This would need to be mentioned on this page maybe:
