Re: Miracle Super Gold card

That would be tremendously helpful over here as well. I'm sitting on piles of 68EC020 and 68EC030 CPUs and DRAM here.

Re: QL 34th Anniversary new hardware.

Since we have no way of knowing what extensions may be added in future, it just seems conservative to spend the 50 cents to provide separate regulation for them. I don't know if the Q68 has one or two LM1117-3.3's but even with two, and a heavy consuming keyboard and mouse that could leave as little...

Re: QL 34th Anniversary new hardware.

There is a separate PC version. The Q68 has no CTS/RTS so it omits a serial level converter. Also, the peak power demand of the card is slightly more than the Q68 could be assured of supplying so it uses a USB power supply. Finally, the firmware for PC and QL is slightly different. The QL version un...

Re: TF Services I2C drivers

It would be nice if it could be. It would be nice if we could have a cheap PLD do just this service and provide it quickly and flexibly to all the other QL platforms besides the Q68.

Also, with a parallel to serial shifter built in, so we don't have to bit bang ;)

Re: QL 34th Anniversary new hardware.

Any use to build a CNC ? OK, found this for people interested, good tutorial : http://www.electronics-tutorials.ws/blog/pulse-width-modulation.html If you're looking to build a cheap but useful CNC, with X, Y and Z axis, what you need is simply one of these: https://github.com/synthetos/TinyG/wiki ...

Re: QL 34th Anniversary new hardware.

I assembled ten dongles. I will make eight available and be keeping two for myself. People who post here can reserve one. I have 20 PCBs, I understand my Q68 may be on the way sooner than I expected. I should be able to post some fun videos of one in use in the coming weeks. For those interested in ...

Re: TF Services I2C drivers

Thanks Tobias. While it may look like a dead end, it may provide the thread for a spark of an idea. There are now at least three different people struggling with serial/SPI/I2C - maybe we should all come together and unify around a common solution so we have something standardized between us and a s...

TF Services I2C drivers

In all the strange places to find something exists, I found specific references to QL I2C drivers in the I2C wiki. Further googling has turned up no further info. I have no desire to disturb Tony's nap; does anyone have any documentation on these drivers? Are they a part of TKII or are they discrete...

Re: QL 34th Anniversary new hardware.

Interesting device ! For the Q68, wouldn't communication through the I2C port be faster than using the serial port ? It would be *much* faster. I do have plans in that area - I just wanted the first board using the device to be available on most of the faster machines all in one go, and accessible ...
