Com3, Hardware PWM conflict ? - Ron A. Nucci - Apr 21 0:03:00 2001

Does anyone know if using the dual hardware pwm (uses timer1) will work with com3 on a bx24 at the same time ?

Does com3 use timer1 ?

Thank you

acording to the docs com3 should be ok with timmer1

com3 uses timer2 --- "Ron A. Nucci" <> wrote:

Tony

I just searched again all of the documents from NetMedia and could not find
information on which timer com3 uses - can you point me to the manual and
page ?

Thank you

Tony

I just found an archived message from Jack Schoof at NetMedia telling how on
the BX24 Com3 uses Timer2. I know it ain't in the doc's ! but you had it
correct ! - Thanks again

Thank you

Re: Com3, Hardware PWM conflict ? - Tony Brenke - Apr 22 0:16:00 2001

that was a part guess on my part.
com 1 uses timer1
com 2/3 used timer2

I figured that being the case there is no problems there.

'=================================================
Potential system resource conflicts
For example, the Com1 device uses the same hardware as the built-in
network (BX-01 only), which means Com1 and networking should not be
used in the same program. In other words, if you want to use Com1 for
RS-232 communications, then the network is not available. Conversely,
if you use the network, then Com1 is not available for RS-232
communications.

Another example -- internal to the BasicX chip is a hardware timer
called Timer1. The timer is used by the Com2 device as well as
procedure InputCapture. If you open Com2 as a serial port, it is
possible that InputCapture may conflict with serial communications. If
serial data arrives at Com2 while InputCapture is executing, data may
be lost. Similarly, if you transmit data from Com2, and call
InputCapture before the output buffer has finished transmitting, the
output data may be garbled.

'====================================================
I got this to mean that timer1 is used by com2(bx-01) and com3 (bx-24)
sence com2/3 and com1 can be used togather com1 used anther timer.

that means that timer2 is used by com1 (bx-01 and bx-24). --- "Ron A. Nucci" <> wrote:
