RTC Query

[t0nyt]

Here's a link to such an adapter kit: https://www.horter-shop.de/de/i2c-pc-ad ... 60547.html

(Note I haven't tried wether that works with the QL, but don' see much reason why it shouldn't. These things seem to be doing the level shifting and clock generation, there's still some software to write)

Won't work directly, since it uses the DSR line which the QL does not provide.

Oh well, more items for the spare parts box then!

I do have another plan that’s already in progress though, and a plan C

Here's a more suitable possibility for the QL's limited IPC serial. Uses a PIC12F675, you'll need MAX232 level shifter and RTC module (w/- EEPROM). Only hiccup is BAUD default is set to 38400, don't know whether BAUD_RS232 equate can be lowered to 9600 - need to look closer at PIC datasheet and source files (included).

Thanks for the info, but I think I'm going to park the I2C idea for the moment and try some other ideas

I2C is now getting beyond what I'm comfortable with trying to do

Many thanks

Hey t0nyt;

I think youre idea is great for getting the time.
But what about NTP time?

I am currently testing an ESP32 the TTGO T-Display + an rs232 to TTL print.
My goal is to be able to perform modem like commands from ql to ESP32.
Which would give many possibilities

The ESP32 Connects to Internet and gets the NTP time.

At the moment Ive got NTP working.
The QL can send serial a command <d>
And the ESP32 T-display will answer serial the NTP time.
This already works ok.

There are many things more one could think of, like getting the weather send a telegram message etc. etc.

Maybe an idea for you?

That’s looks great, but probably still beyond me at the moment

My next experiment, when it arrives, is to try to connect a wi-fi modem to the QL and write some code on the QL to grab the time from a BBS or something. Probably another dead end idea, but it’s fun to try these things

Many thanks

I wonder if those serial network modems would provide time?

Interesting thought

I did look at the one in your link but it’s out of stock. I had to go further afield so while I’m waiting for it to arrive I might take a look at the source code on GitHub to see what functions it might have

Hey Pr0f ;

Someone was way ahead of me
Anyway its great to try to program such nice connection.
And one can make your own preferences.

Just had a quick look at the commands and it seems to support setting up an NTP server and querying the date/time

Looks like the hardest part will be getting it working but it’s meant to work with QL, Speccy, C64 etc. but no idea if QL was using built-in serial ports. I guess I’ll find out soon enough

I do like the lilygo products though - and there is probably a lot more this could potentially offer - would be interesting to see how well it works with the QL serial ports - they were never the QL's greatest strength.
