| Maxdamantus | Hmm.. I wonder how likely it is that some random mini bluetooth keyboard will support USB. | 13:32 |
|---|---|---|
| Maxdamantus | Have been thinking of just making my own slide keyboard that I could attach to a case for a new Android phone, and preferably connect using USB. | 13:32 |
| Maxdamantus | I can see that some companies have made phone cases with sliding bluetooth keyboards, but they all seem to be discontinued, can't see where I can even buy one. | 13:32 |
| Maxdamantus | I bought some random cheap mini bluetooth keyboard to see what sort of hardware was inside, just bought one of the few that I can see for sale in my country (NZ), so didn't have to wait weeks. | 13:33 |
| Maxdamantus | the one I got doesn't have USB support. It uses a special-purpose Bluetooth HID SoC, BK3231Q, which doesn't have any USB support at the chip level. | 13:34 |
| Maxdamantus | (only has UART/SPI/I2C) | 13:35 |
| KotCzarny | if you know how to program some stm32.. | 13:57 |
| KotCzarny | you can make your own interface | 13:57 |
| KotCzarny | and i guess there are ready made solutions | 13:57 |
| Maxdamantus | I suspect it would be easier just adding in some UART to USB chip instead of trying to replace the existing chip with something like an STM32. | 13:59 |
| KotCzarny | it would have to be very power conscious too | 13:59 |
| Maxdamantus | I guess the UART convertor wouldn't be too bad a solution. Might try connecting a UART to it to see what it actually produces. Can't really tell from the datascheet whether it just automatically emits key states or something over UART, or if it's just meant to be for flashing or diagnostics or something. | 14:00 |
| Maxdamantus | I imagine UART to USB chips shouldn't use too much power, and I would probably try to make it so it's only physically connected to USB when the slide is out. | 14:02 |
| Maxdamantus | when the slide is in, there shouldn't be any power draw over USB. | 14:02 |
| sicelo | Btw, modem on my N900 did finally give out permanently, it seems. So now I've been using Droid 4 with Android. When I have time, I'll try using something to press on the N900 modem and maybe get it working reasonably well for basic linux stuff | 14:53 |
| sicelo | I have another N900 with broken USB port. There was an unsuccessful attempt to repair it, and some of the pads got ripped off. Now I wanted to fix it properly, but there's a mysterious short been USB Vcc & GND :-/ | 15:05 |
| totalizator | ripped pads & mysterious short made my day ;) | 17:09 |
| totalizator | I also got one n900 with broken usb but it's still waiting for a proper treatment; I saw some tutorials but I'm still not convinced that I should try; what can you recommend? | 17:15 |
| crab | heh | 17:57 |
| crab | im amazed i never broke my n900 usb port. | 17:57 |
| crab | ive never been careful with it. | 17:57 |
| sixwheeledbeast | i get the feeling some devices were worse than others | 18:03 |
| sicelo | totalizator: ripped pads should cause a short? :-/ | 18:19 |
| sicelo | crab: do you use it daily :) | 18:19 |
| totalizator | well mine main unit never got broken; maybe because I have read about that bug soon enough | 19:19 |
| totalizator | but I was never gentle when plugging in the charger | 19:21 |
