Hi, the manual mentions i2c and UART ports, but there is little info about how to actually send signals to the pins from the Tauon OS. Could we have some quick pointers please?

hello,
UART port is available as /dev/ttyS0 or /dev/ttyS1 on your system. Just connect the device to the pins on the board and you can freely read/write to it by usual Linux commands.
as for I2C, it requires driver which is not ready yet.
However, if you would like to go deeper I can share IR driver source code so you can modify it to use pins that usually serve for IR communication for the purpose.

The joy of this machine is that it is open, I would like to try playing with the driver code. Will you post it to the DL section? |

Hi, i'm interrested by also. Do you think we can access those ports in basic or pascal programs ?

So time to mod it with a tiny TTL to RS232 board with adding a standard 9-pin connector.
I am looking forward to see I2C also available soon.

How will be possible to acced i2c port ? It will be possible to use-it by basic or another language ?

hello,
i2c port would be available at some point in the future. hopefully, It would be accessible as any other device in Linux - as a file.
Sharing only IR driver code wouldn't help a lot, as to compile it you need to build the whole SDK.
If you really want to go this deep let me know and I will share whole firmware as an archive.
At this point, the best option for you to use I2C is to connect Arduino through UART port and forward traffic to I2C device.
You can write to UART port with usual file read/write commands to /dev/ttySX
