Which JTAG debugging device for RPi 3 B+?

I'm looking into doing some systems programming on the Raspberry Pi, and I need to be able to do OS-level debugging, and I have been lead to believe that to do this I need a JTAG debugging device. Which is a good one that will work with the Raspberry Pi 3 Model B+? My desktop computer runs Windows 1...

Awesome. Thank you. That is very useful as I have quite a big project on the horizon.

Are discounts available if you order in bulk?

I was just wondering if it would be possible to get discounts on Raspberry Pis if you order in bulk? I'm looking to order a fair number of Raspberry Pis, and it would help if I could get a bulk discount of some sort. If it is not possible, it won't be a show stopper, but I need to try and save as mu...

Re: Solution to use same keyboard and mouse as desktop PC?

Thank you all for the replies and sorry for the delay in replying to the questions. I want to use the Raspberry Pi for operating system development so I need a hardware option because SSH or any other network connection won't be available. I've done some looking, and it appears that I can get an HDM...

Solution to use same keyboard and mouse as desktop PC?

I've got a Raspberry Pi 3 Model B+, and one of the things that stops me using it more is that I only have a small desk with a single keyboard and mouse. I'm under the impression that a KVM is what I want but can anyone recommend something to use so I can flip a switch and the keyboard and mouse swit...

Does the Raspberry Pi 3 Model B+ support Wifi Direct?

I was just wondering if the Raspberry Pi 3 Model 3+ supports Wifi Direct at all? I couldn't find anything on the product page that mentions it. If so I assume I can use Python as I would on any computer to access its facilities? Does it just require regular TCP/IP socket programming or is there a se...

I was just wondering if the version of Mathematica included with Raspbian is limited in any way or whether it was the full software? There are certain things that I have tried with it that haven't worked, and the example came straight out of the documentation, so I'm not sure if it is a mistake I am...

Re: 32 bit and 64 bit ARM Disassembler

Have you tried https://onlinedisassembler.com/odaweb/ I realise it doesn't convert it into pseudo code and it only disassembles it into asm but it seems like the closest thing to what you want apart from objdump. It does have agraph to display the flow of the program though. That looks like a cool ...

32 bit and 64 bit ARM Disassembler

First of all, I know about objdump and IDA Pro. The problem with objdump is it is not the friendliest of tools on earth to use and IDA Pro costs thousands of dollars to buy so is way outside of my budget. I was wondering if there was something in the middle somewhere. A tool that offered a GUI and m...

Found an old Raspberry Pi - not sure what model it is

I was looking around in the cellar yesterday and found an old Raspberry Pi with an SD card in it. I immediately put the latest version of Raspbian on the SD card, but I can't for the life of me remember what model the Raspberry Pi is. Is there any way to find out the model number without turning it ...

Re: RF receivers that can receive signals higher than 433Mhz?

I'll look into the rtlsdr then. That sounds like a good starting point. I'll have to buy a book or something about radio as it is a subject I don't know much about. It is certainly interesting though. I'll have to brush up my maths as well so I can do FFT so maybe a maths book as well. Whilst based...

Re: RF receivers that can receive signals higher than 433Mhz?

Sorry to keep posting here but I've been reading about the RTL-SDR dongle, and it looks good to start out. Especially as getting that and an antenna is pretty cheap, but one thing I'm confused about is how to access the dongle from my code in Linux. I couldn't find anything about interacting with th...

Re: RF receivers that can receive signals higher than 433Mhz?

I just did some reading on software-defined radio because I don't know much about it and it seems there are also software defined antennas as well. Building a spectrum analyser could end up being a rather exciting project if I can figure out what hardware I need. I found a device called the HackRF ...

Re: RF receivers that can receive signals higher than 433Mhz?

I want to build a spectrum analyzer so the wider the frequency range it can receive the better. There are a bunch of projects based around the cheap rtl-sdr to do that. Of course radio receiver is only the first part of the problem you also need to thing about antennas etc. There are also related p...

I've been doing some Googling on the subject of RF receivers, and the only ones I can find are 433Mhz, but I'd like to get one which can go much higher than that. It would have to work with the Raspberry Pi 3 Model B+. Can anyone suggest any hardware that might fit the bill? I know equipment exists...

Re: Assembly / C IDE that can remote compile / debug / run

I was looking around on the web for solutions that didn't require a cross-compiler and came across xrdp. I can now use the Windows 10 Remote Connection client to show the Raspberry Pi desktop, and I can use GVim from there, so that is a decent solution for the time being. Of course, if I ever wanted...

Thanks for the responses. I guess I'll have to cross-compile and build on my Linux virtual machine and then SCP the files across. Not ideal but it should work. I was hoping to avoid having to build a cross compiler as that seems to be a major pain. I'll look into Eclipse and Netbeans and see if I ca...

It would be nicer to d...
