Re: New Pi3B+ Wireless issues

Thanks all, Yeah the WiFi Country code setting in raspi-config fixed it - I'm guessing having to set the WiFi country code was some regulatory thing that the Pi Foundation had to adhere to? Frankly it's a bit of a pain. At the same time as I was reading the forum, I logged back into my Pi on Etherne...

New Pi3B+ Wireless issues

Hi all, Got my new Pi 3B+ today, it's up and running on Ethernet + SSH but I'm having issues with the on-board WiFi. From what I understand, prior to 'filling out' the wpa_supplicant.conf file, I can run an iwlist wlan0 scan command to get the network names nearby. Well when I do, I see this - wlan0...

Re: SD Card Imaging

Thanks all. Yeah I'm using Sandisk Extremes, same sizes. False alarm regarding the WS281x library of jgarff on GitHub. Turns out I built a bad circuit. I confirmed tonight that a brand new Raspbian image with that WS281x library works perfectly on a Pi Zero W - provided you add the Zero W definition...

SD Card Imaging

Hi all, I hope somebody can help. Late last year I spent a long while building a Pi Zero Raspbian setup, with jgarff's WS2812 library for driving a matrix of RGB LEDs. I did it on the original Pi Zero with attached USB WiFi adapter. I was using the bang up to date Noobs Raspbian image from around No...

Re: Waveshare SpotPear displays - Installation

I've actually gotten the touchscreen working now, using your method (Device Tree Overlays), although not the same parameters as yours - From a root prompt - #nano /boot/config.txt Near the end of the file you should see some lines beginning DTOVERLAY or DTPARAM, paste this line in aroundabouts the s...

Re: Waveshare SpotPear displays - Installation

Aw jeez! I guess I didn't stumble upon your instructions prior to finding the stuff about /etc/modules. Probably because yours isn't a Waveshare Spotpear, but does use the same controller chip. That's the trouble I've had all along, your instructions seem very valuable, but this sort of thing doesn'...

Waveshare SpotPear displays - Installation

Hi all. I recently bought one of these screens with the idea of making a Pi Gameboy type device. I've spent the last couple of days in a Googling frustration over the current state of installation with this screen type - not surprisingly the makers docs are crapper than crap, the Pi community have a...

Re: Pi and light painting and WS2811

Hi I'm thinking about driving these led strips too, the raspi is capable of doing it, but because Linux (Raspbian) isn't a real time OS it can't (easily?) be ordered to do it without some other background process disrupting the strict timing signals. It seems a lot of people use python on the pi, wh...

Re: Potential total top tip!

@mtx512 Great! That's pretty much the kind of thing I want to get running on mine for the time being, but also to do a bit of GPIO stuffs for getting data from the 'real world' and making it accessible on a web page. Care to share any resources online that you've come across to help you do this? Or ...

Re: Potential total top tip! CONFIRMED

Hi all. Good point about it mostly not going to work in PCs, most can only serve a couple of hundred milliamps. You apparently need 700 milliamps. Its fair to say all PCs with USB, going on well over a decade, just arent going to work, which accounts for the vast majority. Suffice it to say I'm not ...

Potential total top tip!

Hi all I'm new to the forums, just got my RPi today, am looking at setting it all up still. I got a little surprise when I saw the power connector was Micro USB instead of Mini USB, I've got tens of Mini USB cables floating around, and only one correct type for my phone. I thought I'd go about town ...
