Re: Kernel module for fleshing led on Pi

It would be worth getting the hand of writing user space applications on the Pi first, then moving on the the rather complex task of kernel modules. gcc is already installed on Stretch, get the hang of an editor, get the hang of compiling in userspace. If you are familiar with C on Windows that shou...

Re: Raspberry Pi builtin WiFi keeps crashing

Yes, the originator of the work around was using the Pi as an AP - sorry I should have been more explicit.

Not sure if there is a similar option on wpa_supplicant - probably.

Re: Raspberry Pi builtin WiFi keeps crashing

We've also had a bug report on the github that has a possible workaround that I like people to try. This may not be applicable to all users, but i am not sure myself what these options do, but will try and find out. In hostapd.conf comment out the line wpa_pairwise=TKIP and replace it with this: rsn...

All source code is available on the Raspberry Pi github account (I would have expected that to be easy to find).

Re: Can't get resolution 1080x1920 (flipped FullHD)

I think by default the framebuffer is 16, you can change that with an entry in config.txt. https://www.raspberrypi.org/documentation/configuration/config-txt/video.md I recently made some changes that allow correct rotation of a 1080p display, previous there was a cap at 1200 when rotating that mean...

Re: Prevent SD-Card Corruption

Re: Interfacing 1-lane DSI LCD with 2-Lane DSI of Rasberry PI

I believe so. However, unless you are using the new VC4 driver, you won't have access to the GPU where the driver needs to live, so setting it up will be impossible.

They do sell industrial grade cards (>100 quid/ea for an 8G card). I doubt they'll just toss one in at no extra cost with an order for a Pi...
Why would they? If you want industrial grade, you'll have to pay for it.

Re: raspberrypi for QoS

OK, there is a bit of a fly in the ointment here if you are using the inbuilt Wireless adapter. We have had to turn off the QoS stuff because of a bug in the firmware of the wireless chip. We will turn it back on when Cypress have a fix for the issue in the firmware itself. For more details, see thi...

We won't be selling industrial cards. In our experience (i.e. testing) they give no benefits over a good quality off the shelf card. (i.e. Sandisk). We've even have one make actually lock up after a few uses, not corruption, just some sort of incompatibility. If you mitigate the chances of corruptio...

The issue, as I see it, is you've got the Raspberry Pi foundation saying you can only buy one per person and at the same time, on the forums here, official representatives are encouraging people to buy more than one.

What a bizarre situation! Why don't they simply raise the price by say £1 - £2 and churn them out by the thousands? This would give them a decent profit margin and the extra cost would make little difference to the one-off hobbyist type user. Continuity of supply? Simply don't change it, if it does...
