I mean, smaller HIRES regions could be used for icons, mixed with TEXT through the 50/60hz attributes, also, no?
Yes, anything that can be displayd on an oric can be transfered so theoretically possible.

Re: I2C for the Oric

At the moment a full page of text takes about a second to transfer and Hires about 4 seconds.

It will speed up a little once I get the timings squeezed, at the moment I'm concentrating on accuracy, but I doubt hires streaming would be possible other than as a picture viewer.

Re: I2C for the Oric

Minor Update. Since its been a while since I last posted. Current state of play is :- Working on a telnet client over wifi and bbs connection. I have the 2 way comms working over wifi between the Oric and my PC running Mystic BBS locally. Still lots of bugs, and the Oric display gets corrupted easil...

Re: Sources for MODEM programs

... and because I needed a terminal program for Oric I wrote my own - OTRM or "Oric TeRMinal" in attached OTRM.dsk.zip It works in Oricutron but you have to set in Oricutron.cfg file: serial = 'modem' serial_address = $31c After boot you cat type: atd telehack.com to connect to a telnet site ('tele...

Re: I2C for the Oric

Minor update to I2CCload.tap and source. Fixed the loading of basic programs over wifi. The load routine now sets the variables and arrays pointers at $9c/d and $9e/f to be after the and of the basic program. Without this the basic starts at $501 and the variables at $503 which means on first run th...

Re: I2C for the Oric

There are now a couple of new files on github https://github.com/BadgeOric/Oric-I2C I2CCload.tap along with I2CCload.s (the source) and Socket_Client.exe I2CCload loads high into memory ($9400) and set the "!" extension vector. Socket_Client is a small windows app that connects to the wifi module, o...

Pretty soon I'm going to give this a try - but I'll use the PlatformIO IDE. Heard of it yet?
No, I hadnt heard of it, but looks interesting.

Will certainly give it a try.

Re: I2C for the Oric

I was intending to do a write up of how to setup the ESP8266 module for use with the Arduino IDE but someone has done a pretty good instructable that can be found here https://www.instructables.com/id/Quick-Start-to-Nodemcu-ESP8266-on-Arduino-IDE/ All I would add is that if you don't already have th...

Re: I2C for the Oric

If you are willing to share the schematics and any needed software, and it is, as I expect, a simple circuit, I could ask for help designing the PCB and even building a small batch. I am more than willing to share everthing. At the moment everything is in its basic proof of concept form. The code f...

Re: I2C for the Oric

I probably misunderstood something, but I thought this device plugged in the printer board, thus not interfering with a disc unit. As it stand tt does connect to the printer port. The expansion port is left free for anything else. The module is essentially an arduino, so has lots of extra I/O pins ...

Re: I2C for the Oric

Wow, nice work! Yeah, its a long shot, but I need to ask - is there any opportunity for us to add this hardware feature to the Cumana Reborn, by any chance? Maybe there's a spare pin onboard that could be used? I can only imagine how cool it'd be to have a Cumana with WiFi capabilities .. I dont se...

Re: I2C for the Oric

AND ITS SOLVED!!!!!! :D Its always something silly. The terminal client (RealTerm) I was using to send over wifi was set to telnet mode which split bytes less than #10 into 2 bytes so a #0a would be sent as #0 and then #A. Setting this ro RAW mode solved this. So now the wifi transfer of a hires pic...

Re: I2C for the Oric

Another quick update. I have finally managed to get reliable transfers from PC to Oric (although more on this below). Its all a matter of timings and how many bytes can reliably be transferred in one block (turns out 5 is a good number but will probably use 4 for multiplication reasons). Text transf...

Re: 65C02 computer from first principles.

This is what my breadboard 65c02 computer is based on. A most excellent instructor and his tutorials on breadboard computers are excelent, his simple processor with 2 registers and an alu is a great set of videos to watch to understand the internal workings. Also his breadboard video card is amazing...

There is some code at https://github.com/BadgeOric/OricI2C. Its pretty fluid as I come across bugs and things that need adding, but it does work fdor the real time clock module.
