AES-CMAC python interface
Hello. I would like to use AES-CMAC which is used for message verification/authentication in micropython. It appears the ucryptolib AES code comes from mbed tls which also includes CMAC code. Anyone know if cmac has been stripped out for micropython or do I need to just build a python interface on t...

Re: TI CC1352R
I am not really sure if there are going to be enough resources to run micropython and an rtos on this chip or not. I'd like to compile it and see what happens but really having trouble wading through the makefiles. I am trying to combine the minimal micropython port and a UART example from CodeCompo...

Re: uPyLoader - simple file transfer and communication
I am trying to use uPyLoader with a uart but cannot get the file transfer scripts to the board. My build 1.8.7 does not include machine.UART which uPyLoader is dependent on. What is machine.UART - can I use pyb.UART? Cannot transfer files with rshell over UART reliably either.

Running REPL with code running
Looking for a little guidance. I would like to run code as well as have access to the REPL. As a simplified example I would like to read from an accelerometer periodically and put the data in ram. While this is running and collecting the data I would like to have access to the REPL so I could do a a...

Re: How to change default flash contents?
There are going to be a few changes to make this work with Windows: -wrong slashes in paths I think coming from resolve_path(). cp hangs. -os.path.exists(com_port) isn't going to work with Windows. I'm using --nowait -backspace in repl echoes as ←[K -ls -l works but filenames begin and end in strang...

Re: How to change default flash contents?
I have a board with no USB as well and have been using the script here to change the filesystem contents. Just wondering, dhylands, if you ever finished that program to transfer files to/from internal flash? Thanks.

Re: Trouble understanding python modules
Thanks for the explanation-I had my terminology all wrong. I used the RTC class as a starting point. If I run my code through pyboard it seems to work just fine. If I run it at the REPL I get a hardfault. Any ideas what is different between the two methods which would point to my error? I have the R...

Trouble understanding python modules
I've written a new module using the LED and UART modules for reference. I am struggling to understand a few points and was hoping someone could explain. I can't get this function to work unless I remove the self_in variable. I don't understand how this works. STATIC mp_uint_t fsmc_obj_write(mp_obj_t...

Re: FSMC support strategy
In my application the send recv is all I need. I'm not exactly sure what you had in mind with ustruct. What would that look like? .pack2ram() and .unpackfrom()
