Re: I2C 4 U

Hi all, I’ve managed to get the PWM working to allow dimming of the LED’s etc. I’m going to add a few more procedures to emulate the Adafruit library. Obviously this doesn’t run as fast on a beeb as an Arduino but that’s part of the fun. Martin, after checking all the code etc I’ve had PWM random l...

Re: I2C 4 U

James Just a thought - I’ve almost got the PWM working on the 16 channel servo card using leds at the moment. I’m basically recoding the Adafruit PWM library into Bbc basic. If you have the arm etc in CAD files I can cut acrylic / Perspex sheets 1200x900mm and up to 18mm thick so 3mm is a doddle. B...

Re: I2C 4 U

It is just a 16k rom so you could happily run it from your sideways ram. (I could supply and blow a rom for you if you decide that I2C deserves a more permanent place in your Beeb.) Give it a try last night and it works. Tells me the date is somewhere in 1948 as I don't have an RTC :lol: Just need ...

Hi.

I'm happy to get involved. I'm an iOS developer by trade, but happy to get involved on the Mac side. I don't know how much I can offer on the Beeb side, but I'm happy to learn.

Re: Possibly a stupid question about the Gotek

To expand briefly on jghartson's reply, DFS versions prior to 1.00 (e.g. 0.90) were released on their own on an 8k ROM. From version 1.00 onwards, they were released on a 16k ROM, which included NFS and the TUBE software. Hence DFS 1.2 is actually DNFS 1.2 . See http://mdfs.net/System/ROMs/Filing/D...

Re: Possibly a stupid question about the Gotek

Disk fault 10 is 'drive not ready', which is a typical problem with 8271 DFS and 3.5" drives. The gotek is "pretending" to be a 3.5" drive. I believe there is a congifuration setting on the Gotek to do a "hardware fix", alternativelty use DNFS 1.21/1.22 which implements a software fix. is DNFS a dr...
