To those of you who own a CP/M #CPM capable #RC2014 kit with either a #PropellerVGAGraphicsCard or a #PiZeroTerminal module, there's now a PBM image viewer for your system! Yay!! 🥳​

Note that due to the limitations of serial line speed and ANSI escape sequences, the output on the #PiZeroTerminal will be very, very (painstakingly) slow.

If you use the #PropellerVGAGraphicsCard the output is rather quick.

It is also possible to display the image on both, the #PiZeroTerminal and the #PropellerVGAGraphicsCard at once but the slow transmission of data to the PiZero will also slow down output to the Propeller module.

The code can be found here:

@pikhq it's a nice module, the #PropellerVGAGraphicsCard but note that it is just that. No terminal, no console. @maccasoft also designed a propeller based vt100 PS/2 and VGA terminal module. PCBs for both can be found at OshPark

Yay, I can now also read binary format (P4 type) *.pbm #Bitmap files up to a 320x240 resolution and display them on the #PropellerVGAGraphicsCard of my #Rc2014. P4 binary format means smaller files (~12K) and quicker reading of bitmap data.

So now i can read and display the following bitmap sizes:

256x192
256x224
320x240

320x240 mode required some additonal bit flagging, but other wise works like a charm!

P.S.: I also rewrote the I/O code for reading the files.

Code will be published soon, stay tuned!

producing more 1-bit 256x192 #PBM images to test my #HiTechC code for loading and displaying these on the #PropellerVGAGraphicsCard for the #rc2014

This time cat "Otto" got his turn ...

Today I wrote some quick and dirty C code to load a PBM bitmap file (P1, ASCII format 256x192 b/w) file and display it on the PropellerGraphicsCard for the RC2014 designed by @maccasoft

The image shows a picture-in-picture setup on my screen with the CP/M console running in a #CoolRetroTerm and the output of the Propeller VGA Graphics Card in the PIP-window in the lower right displaying a photo of the official RC2014 sound card moudle I built weeks ago.
