<jimmy1> glima: i've tried using the soletta c api to write to the gpio pin on the arduino, but i am hitting this error, any idea if gpio on zephyr is working?
<jimmy1> failed to open gpio pin=16 for writing.
<jimmy1> WRN:sol-gpio ./src/lib/io/sol-gpio-impl-zephyr.c:110 sol_gpio_open_raw() device == NULL
<glima> jimmy1: which gpio driver is supposed to match the platform? dw?
<Sachiel> jimmy1: arc?
<jimmy1> x86
<Sachiel> I don't think you'll get any gpio working there
<jimmy1> i've got the zypher sample gpio working that writes to pin 16, io8pin
<Sachiel> what device name it uses to get it?
<Sachiel> that's samples/drivers/gpio?
<jimmy1> yeah, i wrote my own derived from that
<Sachiel> what are you passing to device_get_binding?
<jimmy1> i am just calling gpio = sol_gpio_open(pin, &cfg);
<jimmy1> i think it's handled by soletta api itself?
<glima> so it's GPIO_0
<Sachiel> on soletta it is, but what is the name on the plain sample that works?
<glima> you got to make sure the kernel exposes that exactly as well
<Sachiel> jimmy1: check in outdir/.config if that name is there
aguedes has quit [Remote host closed the connection]
<jimmy1> CONFIG_GPIO_DW_0_NAME="GPIO_0"
<glima> do you have GPIO=y, GPIO_DW=y as well?
<glima> CONFIG_GPIO=y
<glima> CONFIG_GPIO_DW=y
<glima> CONFIG_GPIO_DW_0=y
<jimmy1> yep
<jimmy1> well, in the zephyr one, i do, let me check the soletta one
<jimmy1> not in the soletta one, none of them is set
<glima> well, it won't enable gpio in the kernel without those
aguedes has joined #soletta
<jimmy1> so how do i enable them? just add it to prj.conf?
<glima> yes
<jimmy1> ok, i'll try, thanks :)
<glima> np
lolsec has joined #soletta
<lolsec> isn't there testing module for sml?. i was unable to find it
<lolsec> in soletta it is there
<iscaro> lolsec, well, we have the samples
<iscaro> and examples
<iscaro> the simulator..
<lolsec> ohh.so for testing we are relying on running sml on sample and simulator data
<iscaro> yeah
<lolsec> can you tell where interfacing between fann and sml_ann is? i can take idea from it
<lolsec> i mean sml_ann is using fann library
<iscaro> lolsec, one sec
<iscaro> lolsec, look at sml_ann_bridge.c
<iscaro> lolsec, from there sml calls fann directly
<iscaro> lolsec, and sml_fuzzy_bridge.cpp for fuzzy
<lolsec> yeah got it .thanks :]
<iscaro> :]
<lolsec> sml_ann_support is for checking if fann support is there?
<iscaro> ann_support/fuzzy_support is only used when you compile sml withou the respective backend
<iscaro> without*
<lolsec> okay. also I got to know about openIoT summit presentation by soletta. is there any link for that
<iscaro> hmm, I don't know

<jimmy1> glima: Sachiel: gpio working now, after adding the config, thanks
<Sachiel> good
<glima> jimmy1: me gusta
<jimmy1> glima: how big is soletta in terms of library size? i see the zephyr.bin file with my simple gpio app aroud 43k, so soletta around 30k?
<glima> jimmy1: we did not make official measurements yet
<glima> jimmy1: use nm
<glima> and sum-up
<jimmy1> okok
<glima> we're small, but we still did not tackle mem optimization everywhere we could
<glima> (we only started that)
