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...

Re: 16 BIT HX8357C

Which library do you use for Due? Can't you use the same here, too?

What about debugging? Can the stlink be used? i assume its not by the normal serial print?
OK, I understood that as "normal" debugging, and not debugging with serial print via STLink.
Yes, STLink can be used for debugging, but not sending serial printouts over STLink.

Re: 16 BIT HX8357C

One more thing you could still try is to change this line to "#if 1" - thus enable slow control signalling.
The serial output is not relevant yet, but the display should show something.

Re: adafruit_ILI9341_STM for SPI2

What if you use other pins as control pins? Have you tried?

Re: What can & can't it do?

The features supported so far by Arduino_STM32 for F4 are described here: http://stm32duino.com/viewtopic.php?f=39&t=1976.
If you need more, either develop it yourself and contribute to the community, or switch to the alternative cores stm32duino or generic.
