MikroElektronika clicker 2 board

Just received a MikroElektronika clicker 2 board which has STM32F407VGT6 CPU on board:

Does anybody ported MicroPython already or at least has such board?

Re: Free RAM on MicroPython boards

With the new LoPy 1.0.0.b1 fw free RAM is reduced again, now it is 51k only

Re: PyCom choose GPL3

Comment I received from PyCom: The GPL V3 licence ensures all code written moving forward remains opensource. I think that is the premise we all want to see... correct? Each of our developers need to share code etc Maybe would be better to discuss this issue at the PyCom Forum to get more attention ...

Re: PyCom choose GPL3

pythoncoder wrote:@Lysenko Thanks for the clarification. I wonder if Pycom realise that potential commercial buyers are likely to run screaming for the hills?
Probably not, as WiPy2/LoPy are unusable products and as the situation managed it will be for a long time.

Re: WiPy 2/ESP32 specs and performance

On the device side I'm actually using Microchip RN2483 Lora modules in a tracker and dev boards connected to a PIC32 MCU (not yet running MicroPython). RN2483 is certified by the LoRa Alliance and well documented so you do not have to bother too much on the LoRa stack implementation.

Re: WiPy 2/ESP32 specs and performance

Well, I hoped to use the board in a reasonable time frame for LoRa projects, but it seems to far away. I didn't expect a matured product but the current status was a surprise. It was too early to ship product in this stage. Board itself looks OK, but in lack of circiut diagram and detailed hw info t...

Re: 433 Mhz / FS1000A libary fo micropython?

Grab a cheap DVB-T USB dongle and an SDR (Software Defined Radio) like http://airspy.com/ and check modulation scheme first. BTW, with this setup you can listen FM radio, airband, police, etc. which is a fun :)

A good starting point is http://www.rtl-sdr.com/

Re: WiPy 2/ESP32 specs and performance

In fact current LoPy/WiPy2 firmware is in alpha stage, even I do not cosider it being a beta release :( For example there is an old floating point bug which has nothing to do with the chip vendor but the way how MicroPython ported. Same is for the documentation, LoRa stack is not documented, there a...

Re: MicroPython & PIC32 chips

Hi Dave

thanks for the advice. It is a nice board with the click boards option and definitely deserves a MicroPython port. Probably it would be good to learn MP internals than a new architecture. However for the challeneg is to hav MP on PIC32MZ.
