Have you declared a string containing 'NULL'?

Try remove it and rebuild.

Hi folks, at this link https://github.com/dmazzella/ucryptoauthlib I have created a driver in pure-python for interact with the Microchip's secure element ATECC508A and ATECC608A from a PyBoard. The API are the same of the C library/driver from Microchip https://github.com/MicrochipTech/cryptoauthli...

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 efficiently. what features do you need to port the STM32crypto library to micropython? RSA? certificates? csr? ECC? AES? 3...

try with gc.threshold
try to calibrate the right size for you instead of I suggest you try with a very low value (4096) and increase it.

Hi, yesterday I created a github repository and started a first version of the driver for atecc508a. The long-term goal is to support all devices in the family of the secure elements of Microchip ateccX08a. Now I'm working on the ATECC508A device and at the moment the INFO and SHA commands are suppo...

The problem is that the content of the file "modules/dht.py" is not python code but the text "../../../drivers/dht/dht.py" which represents a symbolic link on unix systems. You are compiling with mingw (but the same problem is with msys2) which does not understand that "modules/dht.py" file is not a...

try this:

The problem is simbolic link under mingw e msys2.
Replace linked files with originals if you need it, else remove unused.

Hi Roland,
have you got the chance and time to try the secure element ATECC508A?

Hi, this is a patch for a modification to the modure.c file that implements sub and other convenient features (I hope). diff --git "a/C:\\Users\\Damiano\\AppData\\Local\\Temp\\TortoiseGit\\modure-74ab341.000.c" "b/C:\\msys64_micropython\\home\\dma\\projects\\micropython\\extmod\\modure.c" index 31c2...
