Re: 16 BIT HX8357C

It turned out that it was no bug in the software, the CS and CD pins were set correctly in another macro in line 187 . Due to not correspondingly working PB2 some coordinates and colors can be wrong, but you should be able to see something on the display. Do you have an oscilloscope? If not, I would...

I started by using that library, but it looks unfinished, so I just ended up doing things directly with the core functions.
The community would be very happy to see your development, this would be a minimum contribution from your side. :)

Re: Hello I am new here

Willkommen, Mike!

All currently supported STM32 cores (Arduino_STM32, STMD32DUINO and GENERIC) are running fine with Arduino IDE, so you should get your things working.
If not, please read this first, and then post your issue in an appropriate forum section.

Re: [libmaple] Generic F407VE mini (vcc-gnd version)

My repo should be functional again.
I had no time yet to test SDIO, but the rest of peripherals should work ok.

Re: What can & can't it do?

That is the so called black F4 board, my link given in my previous post covers the currently supported features by libmaple (Arduino_STM32) core.

Re: Response from Leaflabs about their API Docs pages

Great!
That means, the libmaple core will have some future. ;)

Re: [libmaple] Generic F407VE mini (vcc-gnd version)

Because the SPI pins do not overlay the SDIO pins, the SD cards on F4 boards are only accessible via SDIO (or software SPI but that is not implemented). Please check my posts regarding the SDIO development, and test that version with the timely corresponding repo version. I do currently a global che...

Re: [libmaple] Generic F407VE mini (vcc-gnd version)

Could I just copy FreeRTOS from F1 folder and change the freertosconfig.h, would that work ? Honestly, I don't know, I've never tested FreeRTOS, nor any other OS. Would be a good exercise for someone willing to test. :) Also can I get the on-board sd card working ? SDIO should work as it is listed ...

Re: [libmaple] Generic F407VE mini (vcc-gnd version)

@Manny,
I don't know how you could compare the Dhrystone benchmark, because in the libmaple (Roger's and my) version for F4 the FPU is not yet implemented. I have it on the "todo" list, but did not have yet the required time (also lacking motivation, I have no projects which involves FPU).

Re: 16 BIT HX8357C

I might have discovered a (the) bug. Please replace header line 128 with this line: #define writeCmd(d) { CS_ACTIVE_CD_COMMAND; writeData_(d); WR_STROBE; } So basically setting the CS and CD signal before writing a command was missing. Please try this and let me know the result. [ It is possible tha...
