Re: GD32F103RGT6 custom board

There isnt a lot of difference between the STM32 and GD32 processors There used to be a separate GD32 core, which was for some small boards which have a 12Mhz crystal, but I removed it ages ago, however you may be able to go back through the github commits and find it. I recommend you make a new var...

Re: Reading "User data storage option bytes"?

You can also use the EEPROM library which uses Flash to emulate the EEPROM on AVR and does not normally get overwritten as you can pick a flash page at the top of the available Flash, which won't get touched unless your program takes up all the pages in flash. There are also a few bytes of special r...

Re: Reading "User data storage option bytes"?

Can you just read and write to these locations, or does a page of flash ( or similar ) need to be unlocked first

Is there a limit to the number of times they can be written to, e.g. Like the number of erases for pages of flash

Re: TEK 4010/4014 Vector Graphics terminal DEMO

I don't think its worthwhile doing fill's with lines

Its better to find a python TEK 4010 client and add a new command for fills

Re: Protecting Bootloader from being Corrupted

Like Prolific did for clones? :shock: Possibly I know that one of the JLink updates seem to have bricked the clones. But I seems to get random bricking after using them for a while. I presumed this was basically the same thing, but until @dannyf mentioned it, I thought perhaps it was only me that h...

Re: TEK 4010/4014 Vector Graphics terminal DEMO

BTW. I took a look for vector asteroids code

I can't find a definitive source but there is some interesting code in this blog

Another thought...

Is there a python based TEK emulator?
