  1. Old, save, and list all work. Have not tried accessing from within Basic or machine language programs yet. File format is readable on my mac, ie listed text files. PGM files are in "internal" format, ie binary Basic tokens. Cheers, Keith
  2. When in rains it pours! Here is my completed variant. I am from Alberta and some Canadians call this province the Texas of Canada. So, I dub my build the "Alberta Instruments Brain 2020". Here is a short Youtube video as well... Cheers, Keith
  3. CHEX A custom character editor for the CC40 Here is a program I made for the CC40 to aid in designing custom characters. It is about as close to a MSPaint program that can be implemented on this little computer. Seven characters can be custom edited to create any symbol you like within a 7x5 matrix (8x5 if the underscore is included). This program allows you to edit the pixels in all seven custom characters at once. On start up, existing custom characters are cleared and you are presented with the code for custom character 0, which when blank is 0000000000000000. Look carefully, and you will notice the "cursor", a pixel, is flashing. Press the space bar to toggle the pixel on and off, or press the arrow keys to move the pixel cursor around. If you move the cursor rightward enough, the cursor will jump from custom character 0 to custom character 1 and it may be edited. You can move rightward through all seven custom characters and move leftward back to character 0. Whichever character the cursor is in, the corresponding code will be shown and can be noted down for use in other programs. Press the clear key to erase any character. Press the "q" key to exit the program. Hope somebody enjoys this little program! Cheers, Keith CHEX.TXT CHEX.PGM
  4. Got an Arduino and Data Shield working. Was a learning curve, as I have never worked on microcontrollers before and some finagling is needed to get it to compile on a Mac. Make flunked out at setting fuses; seems that third party Arduino clones do not like having fuses changed. Nonetheless, what was compiled and uploaded did the trick. I have so far successfully tried SAVE, OLD, and LIST (to dump a Basic program to a text file). Thank you Jim! Attached some photos of my build. Since I do not have a HexBus type cable on hand, I stacked some headers soldered directly to the data shield and the board just plugs into the rear of the CC40. Keith
