Now having to explain it I thought of this differently and made as assumption to test against. Based on my last post it shows that 64k of RAM is made available but the max block size is limited to 32k, which is not typical and small. My assumption is that because the default blocks used for the file...

Thanks for the reply. Sorry, yeah I also should have been more specific. I am using the STM32F767, for capability and to leverage the existing work done on the Nucleo. For playing around with expanding available filesystem, actually a lot of help from several post by you and others, I realize the li...

This device does have the 512k of RAM, I guess I cannot see the weak points clearly, or I am misunderstanding your point. I can reduce the filesystem size to something less than half the RAM, which is still plenty for most things. I can also break up how I am copying files over if this is a point wh...

I have been working on updating the filesystem flash size based on the nucleo STM32F767 build. I get it to recognize (show is free using an os) a larger filesystem, but unlike my efforts with the STM32F405 edits I get file corruption when passing the 96k threshold (default build filesystem size). I ...

My main need revolves around ECSDA verification. What is needed is ECDSA verify routines for key verification between a device and a mobile app. I am being told that the STM32 documentation for the ECDSAverify function (in section 10.2.20) is what is needed. I would like direct STM32 support, but us...

I am interested in helping with developing and supporting your development. I emailed you directly so we can discuss. I am also looking into seeing if I can find somebody to help with evaluating porting the STM32crypto library to Micropython. I just do not have the time or knowledge to do this effic...

Hello, I know this is a late post, but most of my SPI problems have been because the Mode has not been set right or because the wiring (especially when hacking together a development board) did not support the speeds. I would double check the mode the device is designed for, and then lower the speed...

Hello, I was asked to potentially review replacing some old hardware with a smaller and cheaper device that communicates with the SOAP webservices but now with Python instead of .NET. I think it would be interesting to take that a step further and try to do it in Micropython. I have only started to ...

I have not had issues with the uart on the Wipy modules, so if there really is something wrong with the uart implementation it is localized to the micropython.org port. I remember hearing that many of the pycom features would feed into the micropython.org port but not sure how that is going. One thi...

There are many different GPS modules available, and even thought they mostly use AT commands they can easily be a little different. Most of them also use RS232 TTL and mostly do not require drivers because of that. I would suggest picking a common GPS module and working with it using a terminal prog...
