Hi folks, It seems I've joined the multiples of people who have this issue with the Broadcom 43438 wifi adapter through seemingly nothing but a raspian update. I've had a Pi Zero running my house lights and hifi for many years without fail, wifi attached constantly. I can't remember why but for some...

Wow, page 2 already! I've just spotted this - https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=269233 which makes me think I've got the same faulty BT packages. I'll check the versions tomo....later today. I know my keyboard and mouse are OK because I installed an ASUS USB BT4.0 adapter i...

Hi folks, I've just resuscitated a Pi3B v1.2 I bought for retropie purposes a year or two ago and now want to hook up the bluetooth keyboard I originally bought for it. Wired keyboard/mouse has always been OK, so once I put the latest Raspbian on a 16GB Class 10 card I booted up and headed to the bl...

Hi folks, For ages I've had a Pi Zero (original edition) running a combo IR blaster/RF433mhz transmitter I built from an AM/FM radio someone gave me in the 90s: PiRF433blaster-small.jpg (The angry red light visible in the top is the Arduino nano doing the IR blasting) This week I upgraded it to a Pi...

If that is the only error I made in that list then I am not doing too bad

Heh

I've bookmarked the list, always handy to have around!

Hi Wayne,

Your PP22 and PP23 are the wrong way round, PP22 should be D+ (green) and PP23 should be D- (white)

Cheers

Heh, at least you've got going - with blasting or just receiving? I'm thinking that rolling my own 4.4.8 kernel with Bengt Martensson's 'multiblaster' lirc_rpi.c isn't a good idea, but even with the 'stock' lirc_rpi and the 4.1.19 kernel I couldn't get blasting to work. Receiving seems to work best ...

Interesting, so you created a WPA network and connected OK? Mine's WPA2 only but still connects OK with NOOBS, just not Raspbian. Time to compare both and see if there's anything glaring with the wifi setup. I know the rtl8188cus adapter needs an alias to work with the 8192eu driver so maybe that's ...

Hi folks, I'm having an issue with SPI on a Pi2 but not a Pi Zero so I think in the past I've blown the MOSI pin on the Pi2 somehow. Background - a while back I was using the Pi2 to read/write the flash chip on an old Technicolour router which used SPI and managed to brick the router even though I c...

Hi folks, Has anyone come across a definitive LIRC blaster tutorial for 4.x kernels? There's so many different versions/gotchas/snafus out there going back to 2012 that I'm tying myself in knots. It should be easy - stock Pi2 w/NOOBS 1.9, kernel 4.1.19. /boot/config.txt changed to enable lirc-rpi ov...

I have exactly the same problem on the March 2016 edition Raspbian (kernel 4.1.19) with the same Wifi chip. If you use NOOBS 1.9 instead of Raspbian it will work and so far I haven't chased down as to why. Also with NOOBS I built a new 4.4.8 kernel using pi defaults trying to get a LIRC blaster work...

Spot on, I forgot about those so I've added a .1uF ceramic to the transmitter circuit and it works nicely now, thanks for the suggestion!

Just needs tidying up/board size reduction and the light sensing code adding since currently that side of things is running on an Arduino

Replying to myself here but this is interesting. Using a logic analyser I sampled the pulse data going to the RF transmitter whilst the board was directly connected to the Pi, then sampled again while it was connected by jumper wires. This is directly connected piZeroWiring4.jpg This is on jumper wi...

Oh I've fought that decision constantly ever since I added that right-angle connector :lol: That connector looks great in a t-cobbler but like you say reverses the pin numbering. The prototype board has a suitable pin layout on a sticker on the back and I checked the power pins on my DMM before wiri...

Folks, Building a little add-on for a Zero with a 433mhz transmitter and headers for console and light sensor for no other reason than 'because'. I have a few night lights around the house that I've bought remote control sockets for and it would be nice to control them from the Pi. That side of thin...

Evening! Yes, could be, I've just thought of that again. Problem is I don't have any HDMI monitors so I'm using an HDMI-DVI cable. I get the same result from an active HDMI-VGA adapter too and the only thing they have in common is the mini-adapter. One thing I've noticed is I can now fudge the frame...

Anyone? Just built a new Jessie SD last night and it's the same, video wise.

Hi folks, I have a puzzlement with the video on a Pi Zero which isn't really an issue since it'll be running headless but it's bothering me :) My original Pi2 setup has been working fine since day 1 with an iiyama pro dvi-d monitor using an HDMI-DVI cable. 1280x1024 @ 60hz, 5:4 aka DMT mode 35.
