| JEEB | hi. any tips if I want to start hacking at making a proper driver for a USB ISDB-T receiver for which I already have a command line app that seems to feed the thing a firmware + be able to tune?
(also any recommendations for a cheap modulator for a test signal while I'm outside of ISDB regions?) | [21:53] |
| iive | JEEB, btw, is it usb dongle? | [21:55] |
| JEEB | yes
Keian FSUSB2i officially KTV-FSMINI | [21:55] |
| iive | is that program something you wrote in C, or binary you got from manufacturer? | [21:56] |
| JEEB | it's an open source binary by someone who RE'd the windows driver I would guess | [21:56] |
| iive | mchehab, crope ^
JEEB, do you know what tuners and other chips does this device use. aka some of them might already be supported by the kernel for other devices. | [21:58] |
| JEEB | it9175 is what is mentioned in the USB/FW/demod code
so I would guess that is the name of the chip https://github.com/jeeb/recfsusb2i/tree/master/src | [22:04] |
| iive | sound familiar
there is already support for it9135 tuner. linux-source/drivers/media/tuners/it913x.[ch] by crope :) JEEB, hang around in this channel, developers would eventually come. but it might also be after the weekend. | [22:07] |
| JEEB | sure | [22:12] |
| iive | looking at the older tuner source code might be good idea. the new one might not be so different. | [22:13] |
| JEEB | I was more interested in the USB DVB device generic framework stuff. where I could just start playing with doing the same things as the cli app :) | [22:15] |
| iive | most dongle are based on some common chipsets, e.g. em28xx
it does the usb and i2c/spi/ etc communication part. | [22:22] |
| hum, the code in the repo, some parts are gpl v3, kernel is v2 only. some do not list license... | [22:30] | |
| JEEB | which is why I did not say I would copy code
according to readme it's GPLv3, supposedly although if the person is poked it's likely he could relicense it if it's his own code | [22:31] |
| b-rad | check out drivers/media/dvb-usb-v2/af9035 bridge
(with extra usb in path) | [22:36] |
| JEEB | cheers, will check | [22:38] |
