Actually most of the credit should go to Magnus - he wrote the Verilog part of the I2C interface for the Pepino board.

There are dedicated 'registers' for the I2C interface. It uses two of the spare pins (+ power and GND) in the Pepino socket that can otherwise be used for GPIO (or SPI for that matter). That is one of the advantages of the FPGA boards over the hardwired MCU boards. You aren't restricted to the connections that the hardwire designer decided. Often you can reassign a spare pin on an FPGA-based board for another purpose just by changing a line in the Verilog 'ucf' constraints file. Regards, Chris Burrows (not Chris Glur)

Oberon Splines.Mod
by Tomas Kral 05 Apr '16

05 Apr '16

Hi, Now reading more about Draw.Tool, PO.Application chapters describe basic shape primitives, a line, rectangle, circle, ellipse, also Spline curves. Splines.Mod however seems missing on RISC.img, I also searched old ETH archives, and not found in sources there nor in Project Oberon 2005. It seems left as homework for a careful reader, right? Cheers -- Tomas Kral <thomas.kral(a)email.cz>

Horizontal scroll of Menu items
by Srinivas Nayak 04 Apr '16

04 Apr '16

Dear All, Now I am using OLR. In some Oberon installation I had seen horizontal scrolling of Menu items with MR click. Now I forgot where. Can any one kindly remind me? I am not able to see Edit.Store menu on System.Log. Only Ed is visible. :-( MR click is not working. Same case in NO on vbox. :-( -- With thanks and best regards, Yours sincerely, Srinivas Nayak Home: http://www.mathmeth.com/sn/ Blog: http://srinivas-nayak.blogspot.in/
