Re: [Emc-users] Micro-controllers

If you go for the AVR, you can get a free Modbus library for it . Actually it looks to be pretty easy to port the driver to pretty much any microcontroller. Les Gary P. Fiber wrote: > I was not aware of Free C language compilers for the PIC's. > I remember Hi-Tech, C

Re: [Emc-users] Micro-controllers

You should take a loop at the Parallax Propeller. It has 8 realtime cores and each run at 80MHz . 32 I/O pins and prewritten objects for many motor control applications. To top it off, it has built in VGA video drivers so you can connect a monitor, mouse and keyboard. A prototype board runs abo

Here's a version of the arduino with a different form factor: It's about half the price of a real arduino, laid out to work with solderless breadboards and comes with and without a FTDI USB chip. If you go for the

Re: [Emc-users] Micro-controllers

http://arduino.cc The only thing you need is an USB cable. A lot of memory, a bunch of timers etc and pretty fast. The card is open sourced. Buy it, build it or get a clone. C subset for programming. When your finished with your project, get a Mini or Nano and make it supersmall. Besides that, it'

Re: [Emc-users] Micro-controllers

Hi Kirk, One of my favorite microcontrollers now is the dspic 30f4011(40pin dip) and 30f4012(28pin dip). They are programmed in C, have enough program memory and horsepower to do significant calculations in complex floating point math. See my VNA project using the 4011 at http://members.shaw.ca/sw
