What is firmata? https://github.com/firmata/protocol
tfirmata is a Tcl implementation of Arduino Firmata:
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...
