Re: CAN BUS STM32F767 Nucleo-144 not working

Hello Two most common problems I have seen with CAN - Default pin assignments in firmware incorrect - CAN is not configured for the clock settings on your board. Check to make sure the CAN is assigned correctly based on the board config https://github.com/micropython/micropython/blob/master/ports/st...

Re: Pyboard-D fwupdate.py config help

Sorry for the late reply, a bunch of work got in the way of fully implementing this. Damien was very helpful and narrowed it down to a couple possibilities. It ended up that I had old mboot and micropython firmware that caused some issues with updating. I also didn't realize that USB DFU does not wo...

Re: Pyboard-D fwupdate.py config help

Thanks for the quick reply. I understand that I cannot write the complete firmware using DFU because of the external QSPI flash, but I am having issues with flashing MBOOT and it feels like I am in a non-recoverable state with the SF3. So just to clarify this is only in respects to getting mboot on ...

Pyboard-D fwupdate.py config help

I am working with some F722, F723/F733, and F767 versions and trying to get the fwupdate tool to work with these boards. I have been using fwupdate with my custom F767 board for some time, but for some reason when I try to use the fwupdate with these boards they just hang in the mboot bootloader mod...

Re: Pulse counter without interrupts

Thanks for the help. Really helped to push me in the right direction. I was able to search more specifically about using the encoder inputs I found some more resources. Of course some of the helpful resources are from Dave (dhylands). Discussion thread https://forum.micropython.org/viewtopic.php?f=6...

Pulse counter without interrupts

I am looking to do pulse counting that does not rely on interrupts on a STM32. I have some other communication and functions that I would worry might cause missed pulses if they have a higher priority, or the counter interrupt those important functions. My hope is to use one of the counters with ext...

Github sponsors

I am a big fan of Micropython and besides buying a fairly significant amount of boards, supported kickstarters, and payed Damien directly for custom work I would like to find ways to more consistently give. Github sponsors is just coming out of beta, and if Micropython joins soon it looks like githu...

Re: mboot from mounted SD card

You are correct, the intent was to use the fwupdate.py with the zipped DFU firmware. And yes the hope is that it could be done from SPI flash device, since it is a common storage method and relative to microcontrollers nearly unlimited in size. You do bring up some good points regarding what MBOOT w...

mboot from mounted SD card

I have started working with using mboot from the filesystem on a device with plenty of filesystem thanks to an external flash chip. So far I am very happy with this setup, and it is not too different than how the pyboard-D is setup. I might be running into a project where support for an older design...

Re: Freezing / Compiling raw binary data in DFU

@pythoncoder Very fair point, and the wiki would make more sense. It is unfortunate that the documentation, forums, and wiki are not always the easiest to search, but it could easily be argued that eventually any body of knowledge gets hard to keep track of and fully utilize. I am also guilty of not...
