More NetBSD/toaster stuff (Updated)
OK, so this cute baby now also got an
article at The Inquirer,
and Christian von Kleist's posting
in the Slashdot thread
contains some nice details about how the toaster hardware is
accessed from NetBSD by using sysctls:
# sysctl -a | grep hw.t
hw.toaster0.led0_duty = 1
hw.toaster0.led0_width = 8
hw.toaster0.led1_duty = 2
hw.toaster0.led1_width = 16
hw.toaster0.led2_duty = 4
hw.toaster0.led2_width = 32
hw.toaster0.led3_duty = 8
hw.toaster0.led3_width = 64
hw.toaster0.magnetic_latch = 0
hw.toaster0.burner_element = 0
hw.toastersensors0.burnlevel_knob = 1593
hw.toastersensors0.cancel_key = 0
hw.toastersensors0.cancel_key_ticks = 13
hw.toastersensors0.toast_key = 0
hw.toastersensors0.toast_key_ticks = 4
hw.toastersensors0.bagel_key = 0
hw.toastersensors0.bagel_key_ticks = 6
hw.toastersensors0.warm_key = 0
hw.toastersensors0.warm_key_ticks = 7
hw.toastersensors0.frozen_key = 0
hw.toastersensors0.frozen_key_ticks = 10
hw.toastersensors0.toast_down = 0
hw.toastersensors0.toast_down_ticks = 50965
hw.tspld0.board_temp = 40250000
hw.tspld0.board_temp_5s = 40290128
hw.tspld0.board_temp_30s = 40477805
(The board_temp are the temperature in C, multiplied by 10^6, so right now it's at 40.25 degrees C.)
/usr/local/bin/toast is pretty complicated, but a basic toast script works like this:
#! /bin/sh
sysctl -w hw.toaster0.magnetic_latch=1
# user presses toast lever down now...
sysctl -w hw.toaster0.burner_element = 1
sleep 60
sysctl -w hw.toaster0.burner_element = 0
sysctl -w hw.toaster0.magnetic_latch=0
echo "Toast is done!"
Only root has write access to hw.toaster0.burner_element! :D
''
Update:
For the record, here's the
dmesg output of the system booting>
