RiscPCB1.04 and PI_I2S 0.10

RiscPCB
A new version of RiscPCB is available with the following changes:-

Ground planes can now be created within the program
before this creating a ground plane involved reversing a
layer and then merging two together now the ground plane
is defined within the Gerber file.

A new IC creation tool that makes creating multiple pads quicker.

The drawfile output has been updated to include the new ground planes

Included in the zip file is a Tutorial Directory in here you will find PCBs
with instructions on some of the new functions.

I have been using the website https://jlcpcb.com/ RiscPCB now produces
filenames that are needed by this website please see the SamplePCB directory
for more details, you can use the 0406gerber.zip file to try the above website.
They specialise in small quantity production runs.

PI_I2S
If you been following the discussions on the general forum you will know that
this module enables the PI to use the I2S output to drive DAC or DIGI boards
It is supplied with 5 driver programs to enable the use of the HiFiBerry cards any
cards that are based on the same chips could also be used with these programs

I have left the driver programs in BASIC so people could write there own versions
and use the I2S module take care of the sound data.

Thanks must be given to Jeffrey Lee for advice when producing this module.

Both these programs can be downloaded from http://www.mbelect.co.uk/RISCOS/

Haven’t tried RiscPcb for a while – is there a way of designing strip boards?

thanks for both Terry, nice job! :)

@Colin

There is no automatic way of producing strip boards but they are just rows of standard Pads
placed end to end, its so cheap to produce sample boards these days that I dont often use strip
boards now, also they dont work very well with RF which is what most of my designs are.

Tks for the reply.

Has anyone come up with a idea of a universal 2 module backplane that could work from A7000 to Iyonix?

A pci version for the – ti – would also be nice :-)

The Archimedes machines had a 3 row IEC connector on the motherboard for the 2/4 slot Podule backplanes, where as the Iyonix had an edge connector on the motherboard, it was also much taller to clear other components. A PCI version would different again. The only thing they would have in common is a pair of 2 row IEC connectors for Podules.
