hello
i recently ordered two arduino boards and now i try my first steps with
it. i downloaded Pduino-0.2 and uploaded the firmware to the chip. i
encountered a little, but sometimes annoying problem, when using the
board with [arduino]-object. when i enable one or more analog inputs,
the arduino sends so much data, that data sent from computer to arduino
gets delayed, sometimes up to 10 seconds. this makes it impossible for
me to use the outputs, while using the analog ins at the same time. i
use the [arduino]-object as it is (with the hardcoded baudrate of
115200) and i connect the arduino-board directly to one of my laptop's
usb-ports.
i counted the messages i receive from the the analog input, when i
enable it:
1 analog input enabled: ~960 values/s
2 analog inputs enabled: ~480 values/s per input
3 analog inputs enabled: ~320 values/s per input
(and so on)
would it be easy to change the code of the firmware, so that it sends
the values of each analog input with a fixed rate (e.g. 100 Hz)?
You could always run at a baud rate like 1200, so the arduino is not
able to send more than 120 bytes per second.
