Re: Loading programs over wifi

I am not so sure about the exact algorithm, and if it is that simple. For example, in the stm32duino bootloader, if the altset is equal to 1 then the maple bootloader behavior is used, the program is written at 0X8005000 and the page at 0x8002000 is erased. This is a detail that must be implemented...

Re: Partial / old code for a F4 Maple bootloader

Guys I just came across this site that claims to have code based on the Maple bootloader, which works for the F4 However :-( , it doesnt seem to be possible to download the code without logging in, and it looks a lot like those file sharing sites which charge for download (and its possibly based in...

Re: [STM32GENERIC] SDIO DMA

Where did you add the code to show the error codes? let's add that to the bench test to see what kind of errors are we getting. http://www.stm32duino.com/viewtopic.php?f=51&t=2036&start=90#p28184 I mean in the source code, so I can add it to the code. I have uploaded my working files to thi...

Re: STM32F303CC on Cheap Mini Dev Board: Support for SMT32F3

Wahoo :) I just did a transplant of a F303CBT6 onto a maple mini board, and i just programmed it via an stlink v2, and it's working XD. I've got blink running on it. :D. Where can i take this little board from here? Is there a bootloader so i could program it via the usb port? Should i change some ...

Re: pinMode() disables timer even if no PWM mode involved

or you were using the normal ones, then if you switch to the alternate ones for SPI1 then PWM works again? That's it So it is something related to the original pins still being linked to the SPI and possible hold in a certain state. Did you check if the end() method for the SPI port disables the SP...

Re: pinMode() disables timer even if no PWM mode involved

I confirmed it, does not enable the timer device, only the channel. That's true, but it's not the problem. Activating SPI also disables only the channel. The timer itself is still running. This is essential, because there are other channels where pwm may be active on non SPI pins. The problem is ob...
