Well done!
I will adapt my repo to reflect these changes.

Re: Stm32f103C8 External Dac

What is the final goal?
Can't be solved by using a filtered PWM output?

Re: SerialUSB question

You could use the function

Code: Select all

if ( usb_is_connected(USBLIB) )
{
}

Re: SPI.transfer of byte crashes F407VET6?

Here can you see what is supposed to run on my libmaple F4 core: http://stm32duino.com/viewtopic.php?f=39&t=1976 (I2C was also implemented on the generic F4 mini , which should run on the black F4, too). Which macros throw exceptions? P.S: The standard SPI port instantiated on F4 is SPI3. And Serial...

Re: Library ILI9481 320*480 3.5

i would go a bit more systematically in your place.
Only do one change at a time, and then check the effect.
I think you should not change the fsmcData address.

I haven't tried in 8 bit mode, but I could give it a try, just that time is missing...

Re: SPI.transfer of byte crashes F407VET6?

Well, if it is working with Roger's core, why not use it? :?:
By preference, you could also try my repo, it is a bit further developed regarding F4.

Re: Library ILI9481 320*480 3.5

I have tried changing the FSMC to 8bits in the libmaple library, but then the LCD went dead right after the change. I am not sure what went wrong, hopefully you can provide some insights. Please provide detailed information what and how exactly have you tried. I am not sure if it is enough only to ...

Re: problem with gps :( only 0.0000 instead of real data:(

OK, now let's go back to the example I suggested before (corrected version): uint32_t time; void loop() { if ( (millis()-time)<1000 ) { if (ss3.available()) { char c = ss3.read(); Serial.write(c); // monitor the data from GPS on PC --- this is optional, can be commented out gps.encode(c); } // this ...

Re: Serial buffer

It should be possible to specify the size of a ring buffer per device without having to perform your own management of two tier ring buffers by performing unnecessary buffer to buffer copies. Of course it is possible by using dynamic allocation, but not preferred, as malloc() could by case behave o...
