There is a PWM example for the BX-24 in the documentation package. The
name of the application note is Dual_PWM_App_Note_BX24.pdf and there is
example code too. > And the las question. How can I communicate the BX-24 to a Basic Stamp 2?
I think it all depends on what you are trying to do. There are three
decisions to make:
- the hardware protocol i.e. SPI, I2C, RS232, RS485 etc which depends on
chip and physical requirements
- the software protocol i.e. What do the commands look like
- the management protocol i.e. master/slave, multiple master
b
I suggest you post another append with the details of hat you are trying
to do (and even why you need a separate Stamp) and that will help guide
our answers.

PWM - matias domin matte izquierdo - May 31 16:21:00 2005
I want to drive two 6VDC motors. I'm using the L293D to control the
direction and speed, but I need a permanent PWM output from BX-24. Is it
posible? I think that with multitasking this is posible, but I havent' done
it.
Otherway, how can I drive these motors withut adding more hardware?
And the las question. How can I communicate the BX-24 to a Basic Stamp 2?
Thank you very much!

Thanks Mike, I don't understand something. If I use PWM like says the app
note simultaneously with other tasks, will be the PWM signal interferred?
About the comunication between bx24 and bs2, I'm just asking in case I want
to send, for example, 2 bytes between them by RS232 (maybe for having more
outputs). I really don't understand the theory, so probably I'm trying to do
something strange.
Thanks again
