Controlling your World the Easy Way

Well, the PORT command gives you a 32-bit value, which should NOT be considered as a number - rather, each BIT in the value represents the state of one port. So you need some binary operations ( &, |, and ^ ) to get the state of the port. See page 23-24 in the manual. If you use AND and OR comma...

I have used the revised boards, and they are just as good as the old ones - and a little smaller, to boot. Well done! Note, however, that on a Mac, the terminal login to the board is now different: screen /dev/cu.SLAB_USBtoUART 57600 cs8, ixon, ixoff No serial number is needed, anymore. (See the pre...

The "new" version of EzSBC1 has a slightly different login procedure than the old one, when using the Mac OSX Terminal Screen command. This command connects to the new board: screen /dev/cu.SLAB_USBtoUART 57600 cs8, ixon, ixoff (there is no serial number, as with the old boards - thus, the...

Not necessary to switch banks, really. You can write the BASIC code in two parts, one for sampling, the other for processing. If you're short on memory, you can ask the admin about a version with asymmetrical banks. Then you can fit everything in bank 1 and do the switch-over in your own code. BTW, ...

I've successfully implemented WiFi using an ESP8266 module and an EzSBC1 ! The project is a remotely updatable huge LED matrix display for museum use. Data can be sent/received from a smartphone, laptop or PC with WiFi. The EzSBC1 works as an access point, and upon query sends a webpage form which c...

I prepared a short video describing how I built my LED matrix displays:

PB.jpg Running out of both flash and RAM memory (due to several large fonts for big LED matrix displays), I added 24LC512 EEPROM chips to all my EzSBC1 boards, instantly giving me 64 kBytes of non-volatile memory readable and writable from within the BASIC Code - something you cannot do with the Ez...

I'm working on a color light meter (using a "TCS230/ TCS3200 Color Recognition Sensor" from eBay), and need to calculate some logarithms... The EzSBC1 doesn't have a log function, but I found an old, classic BASIC subroutine, here modified for the EzSBC1: --------------------------------- ...

The above info has been updated, and the link to the rather poor video removed.

Thinking a bit "outside the box" I figured out a way of getting really smooth scrolling on up to 8 MAX7219 modules. The trick is this: The modules are connected 90° rotated, i.e. with input at bottom, not left, and the modules are NOT connected in series, i.e. DOUT to DIN, instead, all DIN...

I don't know if anyone plans to build a LED matrix display like the ones I've built, but here's a font displaying program including the 3 fonts I've designed (well, the first is actually from an Arduino website, with just a few small changes.) This BASIC code will run without any extra hardware what...

I enlarged the "Weather Clock" display by two modules (a whopping $ 1.50 each ;-), and it will now display the time with seconds, in the large, condensed, fat font described in another thread. The LED display now consists of 12 modules, 2 rows of 6, i.e. 16x48 pixels, or a total of 768 LED...

Note: You should use ControlBASIC version 0.82 for this project - in older versions, there is a subtle bug in the DHT routines that will freeze the temperature and pressure displays after a few days of running.

Here's another large font for the huge display (will of course work with a smaller one, too) - it is optimized for readability from far away, and also as narrow as possible, in order to fit more text in the available space. The caps are 13 pixels high, so there are 3 pixels at the bottom reserved fo...
