micropython-agps

As a part of porting micropython to A9(G) module https://github.com/pulkin/micropython/tree/master/ports/gprs_a9 I implemented assisted location services (AGPS) for micropython. It, basically, uses internet services or a local database to derive the location via visible GSM stations. Local database ...

Re: Implementing fsobj

It seems like this gives an idea of what to implement: █ grep proxy ../../extmod/vfs.c // For mp_vfs_proxy_call, the maximum number of additional args that can be passed. STATIC mp_obj_t mp_vfs_proxy_call(mp_vfs_mount_t *vfs, qstr meth_name, size_t n_args, const mp_obj_t *args) { stat = mp_vfs_proxy...

Implementing fsobj

Hi, The port I am working on https://github.com/pulkin/micropython/tree/master/ports/gprs_a9 has, pretty much, a copy-paste implementation of vfs where file and folder-related operations are replaced by static port functions. I think that implementing an actual vfs object might be a better choice su...

Re: Mininal Port's Garbage Collection

Does anything prevent you from looking into the stack trace and/or running gdb on it?

Re: Custom port A9G module: help wanted

I have a display over SPI now. It is quite slow. The main reason, I believe, is python library which drives it pixel-by-pixel.

https://github.com/boochow/MicroPython-ST7735

What is the best way to speed it up?

Re: Custom port A9G module: help wanted

It is just something that I was considering implementing. I won't for now then.

Re: Custom port A9G module: help wanted

I am happy to announce that [the port](https://github.com/pulkin/micropython/blob/master/ports/gprs_a9/README.md) is advancing. In terms of hardware, a number of things are working reliably including GPIO, GPRS network, SMS, file IO, system and power things. Now I am looking at `micropython.native/v...

Re: ulab, or what you will - numpy on bare metal

Awesome project. Regarding possible developments, having more of `numpy.linalg` stuff (eig, svd) would be really cool and relevant.
