Trouble getting started

I am trying to get a Rasp Pi Zero W up and running for a project that I'm working on. Here is what I've done so far: 1. Download Raspbian Lite from https://www.raspberrypi.org/downloads/raspbian/ . Leave the downlaoded ZIP file in the Downloads folder. 2. Obtain a micro-SD card. I used a 32GB card. ...

Can't get it to do anything

I have a Raspberry Pi Zero W and am trying to get it working for a project that I have. Here is what I have done so far: 1. Format a 32GB micro SD card using SD Card Formatter, quick format option, on my WIndows 8.1 desktop PC. It formats as FAT32. 2. Download NOOBS as a ZIP 3. Extract the ZIP 4. Co...

Re: Zigbee home automation on Pi Zero W

The original poster said: "Now I am not sure about this but someone might correct me on this but the RPi should be capable of doing zigbee without any extra hardware as it already has a 2.4GHz radio. WiFi, Bluetooth and Zigbee all use 2.4GHz radio but are just different protocols (i.e just different...

Re: Zigbee home automation on Pi Zero W

I'm still confused about the answer to the OP's question. Is it possible to implement Zigbee on a Rasp Pi Zero W with no additional hardware, or not? If not, what is the most cost effective hardware that I need to add? If it IS possible, what software do I need? A related question - what is the rela...

download jessie ????

The reason that I started reading this thread was that the instructions that I've got (Getting Started with the Raspberry Pi Zero W) specifically mention Jessie, and since I am a complete beginner at this, I have no idea whether these instructions will work with the latest version of Raspbian (which...

How do I edit my post?

How in this forum do I edit my post? It is very annoying to complete a post and submit it, and then to notice that you have made some kind of typo and be unable to correct it.

Thanks - Rowan

USN Connections

I have a Rasp Pi Zero W. I can't get it to configure properly without a monitor, so I need to attach a monitor, mouse and keyboard in order to see what's going on. I bought a powered USB 3.0 hub, and a mini-HMDI to HDMI cable to enable this, but now I'm confused about the USB cables that I need. The...

Re: Create LAN-to-Bluetooth Bridge

I am trying to get the commands from the manufacturer. I know that this may well be a proprietary protocol, and that they may not want to tell me the commands. However I may be able to deduce them by sniffing the comms between my smartphone app and the device (assuming of course that they are not en...

Re: Create LAN-to-Bluetooth Bridge

The particular devices that I am currently trying to use are a Bluetooth radiator valve. I need to be able to send the valve commands to open or close the valve, and maybe to part open it (i.e. open it to e.g. 75%). The device also incorporates a temperature sensor, so I need to be able to read valu...

Create LAN-to-Bluetooth Bridge

I need to interface from a PC to some Bluetooth devices that are too far away from the PC to get a good Bluetooth connection. I have WiFi and wired Ethernet throughout the house, so I suppose I need a small device that will create a Bluetooth zone near the devices, and connect to the PC either via W...

Rasp Pi to receive signals from Apollo Oil Level Monitor

Hi, I have an Apollo ultrasonic oil level monitor on tank. I am planning to design a receiver that can receive the signals transmitted (433 MHz band, FSK), and decode them into an oil level, which it can then put on a web site, use to graph oil consumption, detect oil theft, automatically warn me to...

Re: Interfacing to IO pins via 8085 bus

Is there not some kind of address/databus which the processor uses to access external memory, and/or external peripheral registers (like old microprocessors used to have)? If so, then it seems to me far preferable to design an interface between this and the old 8051 bus than to do it all by bit bang...

Re: Interfacing to IO pins via 8085 bus

Thanks very much for your response. With respect to the number of IO pins required in the system, a typical system might have up to 640 pins. A large system, might have up to 2000 pins. These are arranged in 8-bit bytes on the 8-bit 8051 bus. My thoughts are that using a second processor to adapt to...

Interfacing to IO pins via 8085 bus

I work on a system based on the 80320 (8051 family) microprocessor. I'm thinking of trying to replace the main processor with a modern processor that will have much more memory, USB ports, WiFi, Ethernet, Linux or other real time exec etc. There are a lot of special purpose IO boards that I really h...
