Re: generator on a timer with an interval of 25 nanoseconds ?

25 Nano seconds is not 25MHz, it’s 40Mhz

You would probably need to set the clock PLL so the board ran at 160MHz so the timer can have a divider of 4.

Re: Hello from UK

I agree.. Use a Max232, it’s much safer. Re: Australia I think light pollution is bad in all the major cities, and it would take several hours to drive away from the light. Unfortunately the jobs are in the same places as the light pollution, unless perhaps you can get a job at an observatory locati...

Re: usb host contr stm32

Steve Several people investigated a composite device, ( specifically one that did not need drivers on Windows ) but they could not make it work on Windows 7. BlackMagic Probe seems to enumerate as 2 Serial ports and also DFU , at the same time, ( but needs drivers on Windows) But, On BMP, the DFU de...

Re: Hello from UK

Hi Marco Yes. I think its better here than in London, as it is possible to drive away from the light a bit, and there are some places in Australia which have very little light pollution. One holiday we stayed a night at a cattle station in outback Queensland (Somewhere near here https://www.google.c...

Re: Hello from UK

Welcome Marco I have an old Celestron Nextstar telescope (I think its a 4 inch reflector, about 10 years old), but the light pollution in metropolitan Melbourne is terrible, so I've not used it for years. I recall connecting it to the PC control program, several years ago, but I'm not sure what I've...

Re: Avast releases there RatDec decompiler to Open Source

I think it can be used as a plugin for IDA, but I'm not sure if that makes IDA free to use, as its not using HexRays (possibly not)

Re: STM acquires Atollic

The license on Segger Embedded Studio was a bit vague I went to a Nordic Semi, one say seminar, earlier this year, and at that time Nordic told the audience that they could use Segger Embedded Studio to do all but the final build, as that it was OK with Seggers license to do all the dev with it, but...

Guess I was right when I joked that the companies I was most interested in seeing "were too busy acquiring each other."
Yep. acquisitions seem to be flavour of the month.

Just like Autodesk bought Eagle (and ruined it for everyone by changing the license and requiring a login to use it)

Re: BP carrier card advice needed

I'm not sure why you are using SPI. Is it to give you more channels ? Using a board with more GPIO's would be easier. I think the questions about bus length etc, are general PCB design and you are more likely to get advice on a forum like EEVBlog which has dedicated sections. This forum is primarily...
