Re: [IntelCurie] Does anyone work on porting uPy to this?

Dear Peter, I also placed a red flag at every Curie, Joule, Edison, etc. However it seems (and was told by the Intel IoT guys in Ireland) that Intel withdraws from producing boards that support all the different inventor names, however are committed to produce the chips and SoC's. They leave it up t...

[IntelCurie] Does anyone work on porting uPy to this?

Dear,

I'm looking into using the Intel Curie SoC. It would be great if it could run mpy. The CurieSDK also supports ZephyrOS.

Has anyone looked at the possibility and rejected it?
Is anyone working on such a port?

Re: [STM32L476DISCO] RTC not ticking

@pythoncoder Dear Peter, Indeed I noticed when I put my finger on the capacitors next to the 32kHz Oscillator REPL via the USB doesn't respond, and removing the finger everything works again. I tested the L476 port on the original STM32L476DISCO (reference) and two boards of my own making. They all ...

Re: STM32L467DISC port not working?

To be complete: The difference between working and not working is entirely due to the 8-byte alignment of the generated code of the L476 port. If you use DFU-UTIL to program the firmware.dfu you may run into problems when the file is not padded to fulfil the mentioned need. AN2606 of STM for further...

[STM32L476DISCO] RTC not ticking

Dear all, Anyone experienced the fact that the RTC is not running? import pyb pyb.RTC().datetime() should change every time you issue this command. Also setting the clock takes about a second or so before the prompt returns, but no changes to the registers at all. The default time is stuck at (2000,...

Which Servo's

Hello,

Micropython supports the control of servo's.
Are there any particular type/brand of servo's that work well with the py-board?

Regards,

Roland

Re: STM32L467DISC port not working?

It works, however using JTAG to program the image rather than dfu-util, the aforementioned "patch" combined with the randomness of dfu-util showed that it worked, but was not the root cause. So if I have time I will check other "dfu" programs (like python version) to see at which side the problem re...

Re: STM32L467DISC port not working?

I have it working now. It seems that the dfu-util/bootloader via USB experiences some problems. It does load w/o any errors, but the code does not run as expected: - constantly rebooting when USB cable attached - when USB removed REPL via UART can be used, however no file system, crashes randomly wh...

MICROPHY_HW_FLASH_LATENCY compile error

Just a minor thing but if one omits the MICROPY_HW_FLASH_LATENCY in the mpconfigboard.h of the STM32L476xx related boards an error pops up when compiling. See the files in /hal/L4/inc/stm32l4xx_hal_flash.h and /hal/F4/inc/stm32f4xx_hal_flash_ex.h for more. I added this at two places to resolve it. I...
