Re: Chips without support

As I'm the owner of the stm32duino Githug organisation and the main developer well it is easy for me 😉 Well, I would hope so otherwise I'd be in for a rude awakening haha. I think I'll only use one unsupported processor and just have the other ones be similar to what I have picked out so I can try ...

Re: Chips without support

Adding your own variant can cause some pain but also will help to better understand how it works inside :)

Re: Need to change Vector table Address

First check if your jump from bl is working properly, just flash generated bin to exact offset using cubeprog

I found linker file STM32F103RET6_FLASH.ld and I changed flash address there, Is that enough or need to change any other files?
VECT_TAB_OFFSET inside the system_stm32f1xx.c

Re: Nucleo-F030R8 and ILI9341 Changing SPI Speed

No, maximum speed of spi is cpu clock divided by 2

Re: IRF7103 and 3.3V control with STM32

im not sure driving 2+ amps using sot23 is a good idea in terms of thermal stuff
powersop8 or equal is much better for heavy loads imho

and yes, fets with vgs(th) about 1.5v are better choise for 3.3v logic

Re: IRF7103 and 3.3V control with STM32

im not an expert, but datasheet says irf7103 have vgs th min 1 max 3 volts so it should work properly with stm32
