Re: J-Link EDU Mini $18

Yes

It does work

But only with a slightly older version of JFlash etc

Was it you that worked out that version 6.14b was the last version that worked with the STM32 JLink OBD

Re: J-Link EDU Mini $18

Rick I don't know if you have seen this (which uses a STM32F103C8T) https://github.com/GCY/JLINK-ARM-OB This seems to be the hardware design and firmware from the previous generation of the same sort of device Basically, you can make the same thing using a Blue Pill, by connecting PA4 and PA7 via 10...

Re: STM32 with Eclipse, STM32Cube, GNU ARM and J-Link.

I briefly looked at the videos, but found them very slow and yet did not explain clearly what he was doing. In addition to what Rick said.. On Windows you can download and use Atollic True Studio for free, and the STMCube directly outputs project files for it. AFIK, The license on True Studio allows...

Re: J-Link EDU Mini $18

Very interesting. Though I am not sure how useful it would be. I have some Nordic Semiconductor Development Kit boards, which have basically the same functionality of JLink on them, and you can't use the full version of JFlash etc with them. You have to use the cut down "Edu" versions of those tools...

Re: Rebooting to DFU bootloader in F4 and others.

OK
Perhaps someone using a HAL core on the F4 can try it to prove it works

Re: Rebooting to DFU bootloader in F4 and others.

I can't seem to move my post about it.. (in fact I think I've accidently deleted it when trying to move it) So here is the link to STM's community forum https://community.st.com/thread/40238-stm32l476rg-jump-to-bootloader-from-software The final code posted on that site is typedef void (*pFunction)(...

Re: Solved: [ILI9341] flickering on drawstring on large characters.

That would be my thought i.e micro Farad not milli Farad 10 uF isn't that much and it was unclear whether the "fickering" was something to do with the backlight Its possible that the OP is trying to power the LED though a board which does not have a good enough regulator to supply the LED backlighting
