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

Sorry for spamming this thread, found my FTDI breakout and was able to see the benchmark results .. -O3 flag...more like it. Dhrystone Benchmark, Version 2.1 (Language: C) Execution starts, 8000000 runs through Dhrystone Execution ends Microseconds for one run through Dhrystone: 1.78 Dhrystones per ...

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

Sorry, it seems that something went wrong by my previous commit, although I have tested it before. Could you try this version: https://github.com/stevstrong/Arduino_STM32/commits/f83f33f97f5823f56baae7762321aa8d427d03f2 Meanwhile I will check to see what is wrong there. I have a com port with that ...

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). True but...

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

Is this the correct place to report errors with Steve's repo? I just downloaded Steve's libmaple master branch and tried simple led blink sketch with F407VE mini board. Didn't work so tried debugging with the new Atollic IDE and here's the result: Got blink to work but not serial USB...did you chos...

Re: [libmaple] Black F407VET6

Downloaded your repo Steve and cant get serial USB to work or get recognised, using a STM32F407 mini.

Re: RF24

Thanks all, at last I got the RF24 working. Mistakes made : I tried to use SPI_2, but the library only takes SPI_1; I was sending from a arduino uno 7 integer values, but in the uno these are 2 byte values, in the maple mini as receiver these are 4 byte integers. after modifying the transmitter to ...
