What is firmata?
https://github.com/firmata/protocol
'''tfirmata''' is a Tcl implementation of Arduino Firmata:
* Original code: https://github.com/pdt/tfirmata
* documentation: http://www.p-code.org/tfirmata
* an enhanced version: http://www.androwish.org/index.html/dir?ci=68647d69a65029d3&name=assets/tfirmata/src
The original '''tfirmata''' did not work for me on Windows7, I suspect there is an endless loop on the tfirmata::open cmd.
The enhanced version (by [chw]) worked just fine, with the following code as a minimum example:
console show
package require tfirmata
set bd [tfirmata::open COM8]
$bd mode 13 out
for {set i 1} {$i <20} {incr i} {
$bd dset 13 1
tfirmata::sleep 250
$bd dset 13 0
tfirmata::sleep 250
puts $i
}
puts done...
