Re: Andy's Postbag and random ebay links

Just a thought... But but after reading some other blogs etc about these devices, I suspect they are not operating in a way that could be made directional. There is just one transistor that appears to operate as TX, and RX+mixer. So it seems far more likely that its only operating as an oscillator, ...

Re: assembly output

%APPDATA% gets you to your appdata folder on windows

Depending on your version of the Arduino IDE, its either in appdata local or appdata roaming.

I think you can use %APPDATA%\local\arduino15\ .....etc...etc. on the newer versions of Arduino

Re: ARMduino - a generic implementation of Arduino on ARM Cortex-M chips

BTW. Several other people and already use the name ARMduino https://www.google.com.au/search?q=armduino I dont think its trademarked, but it is rather confusinb if you search for that term PS. i also moved it to Cores PPS. As well as @danieleff's STMGeneric core, and STMs own Cores, there is Koduino...

Re: Interesting video for linux users about GDB Text User Interface

Netbeans sounds interesting, but sounds like a massive install, just as a graphical front end for GDB. I did also look at a commercial GDB front-end :D for Windows ( I did post about it, but the name of the product now alludes me.But it was over $100 and didnt seems to work that well.) So GDB on the...

Re: Interesting video for linux users about GDB Text User Interface

I gave up trying to ask the eclipse team to fix issues in the standalone debugger for windows. So i have not looked at it for ages. I guess there is a chance it works now, but I got the feeling no one was working on it. Re:GDB The Text GUI was something I had not seen before. i.e half way between th...

Re: Partial / old code for a F4 Maple bootloader

I thought it should still be possible to upload a bootloader on the F4 via USB to Serial like the F1. Re: Messing around with boot pins. I thought there may be a way to jump to the built in DFU bootloader from code, though I've not tested it https://stackoverflow.com/questions/28288453/how-do-you-ju...

Re: Minimum ADC reference voltage?

Thanks. It looks like he is doing the same thing I thought of, except with the ACS512 being a 5V device, he will get full range of +/- 5A (or whatever the range of his Hall effect device) I just checked my box of spares and I can only find a 30A version (which I bought for mains current measurement)...

Re: Partial / old code for a F4 Maple bootloader

@ag123 umm. I may try on a different Windows machine, but I'm not keen on messing up my existing drivers by using ZaDiag etc etc Hence the reason why I was looking for a better overall solution for Windows users by having a F4 version of the F103 bootloader I'm sure it should be relatively simple to...

Re: Partial / old code for a F4 Maple bootloader

@ag123

I did try that once before on Windows with no success. But I will try again.

Re: Minimum ADC reference voltage?

Yes. I want to measure current of up to 2 amps from USB chargers. I may be able to use an ACS712-5A hall effect current sensor, I think it outputs 0A as 2.5V as its output is 0V for -5A and 5V for +5A (as its directional) So if I put it in backwards ;-) Then I get the full range of 2.5V to 0V in the...
