And extremely low price !

octal, have you looked at Crossworks for ARM?

They are on the page that you linked to.

Those mini2440's sure are nice, aren't they?

You are starting to get into the realm of what is known as multi-tasking. You have two tasks - one to toggle the Red LED every second and the other to toggle the Green LED every 5 seconds. As you have found it can get quite tricky to do it right. It is easy to get a single task going. However adding...

You cannot run PIC code from EEPROM. You could use one of the devices that Jerry mentioned, although that is meant to just increase/extend the amount of the device's program memory - not exactly what you want to do though.

Perhaps another question may be in order. What are you wanting to do where 128KBytes of FLASH is not sufficient?

Hi Robert, Worst case scenario, download the demo version of SF. It has some limitations but it will be many months before you encounter them. In any event, save your work and you will be able to use it with the full version. You can get it here http://www.sfcompiler.co.uk/swordfish/download/index.h...

Anyone know of a real-time operating system (pre-emptive and/or co-operative) that works with SF - or any other dialect of BASIC?

I agree that SF is the best BASIC compiler out there - but it is still BASIC. If this is just a hobby for you, it may be OK to stay with SF and live with the uncertainties it has. I would highly suggest moving to C - it really is not any more difficult to work with and has capabilities/features far ...

Another possibility is the PCA9532. Max. PWM frequency is 152Hz - you can easily set it up to run at a selectable 100 or 120Hz. Available for <$2 from Mouser, Digikey, Future, etc. The PCA9532 is a 16-bit I2C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/B...

You don't need the module identifier or [end].

I would go with the PIC18F452. Download the SF Manual here http://www.sfcompiler.co.uk/swordfish/d ... umentation
Play with some of the canned examples to get an idea of how to set up your project.

If you have not already got your PIC, then I suggest using one of the newer 4 digit devices such as the PIC18F4620.

Try inserting a DelayMS(200) between the HIGH and TOGGLE commands.

Hello rmteo, I need for an application a display that could be sun readable, I need a simple black on white one ... something that can be read under sun. Regards octal What do you think of the graphic OLED on the EA Base Board? Its response time seems much better than GLCD's that even using the SPI...
