Re: Design my own pyboard, basic questions..

I have designed a few boards with the STM32 (407/429) (but also other ARMs) and standardised on using the Tag Connect TC2030 connection with either locking holes when there is room on the PCB, or just the 6 contacts only. It allows for +/-/SWDIO/SWCLK/RXD/TXD. It is time/cost/room saving and I perso...

Re: compiling latest mpy on OSX fails on frozen

Thanks it works.

One observation is that the files in stmhal/modules/ appears in the file system as aliases (links) to the drivers/display directory rather than a file that holds a reference to the directory or the source code itself (as copy).

MPY is getter better and better! Great work!

compiling latest mpy on OSX fails on frozen

I just updated my micropython source to the latest revision, and tried to compile it on OSX. I cannot get beyond the part where the modules (in this case the display) need to be build into frozen code. I did make clean first in stmhal . Then just make to build the code for the PYB10 board. Somewhere...

writing file to /sd from mpy and show it on USB

I'm probably overlooking something but: If I'm dropping a file through USB on the disk, I can use it immediately within the mpy environment. So now I have a program that writes a file 'FILE.TXT' to the '/sd' volume. Closing , flushing and syncing does not show the file at the other side (USB side). ...

Re: TFT or OLED drivers

Great thanks both for your response. Next two months I will probably make a design for it. I will share my result.

TFT or OLED drivers

Dear all, I like to hookup a TFT 320x240 2.4" display to a STM32F429. Using and SF-TC240T-9370-T it seem pretty straight forward as this is also used on the 429 discovery board. However it uses a full parallel RGB interface together with the serial interface for interfacing using the LCD contro...

localization of date/time/decimal

There is some discussion to have sensors report values in SI units. However if an application is developed it is necessary to adapt the way time, date and the decimal point is represented. Libraries like babel address these issues, it would be a great enhancement to micropython. Your opinions and id...

Re: Peak Current Consumption (Power Profile)

@Beta_Ravener: The datasheet can also be found at the Espressif website and other places, but as you can see in the table these are only typical values and no mention of maximum values. There are numerous reports that the current is well over 300mA, but not accompanied with the time interval. I will...

Peak Current Consumption (Power Profile)

Dear all, The ESP8266 has a rather bad data sheet where typical current consumption is mentioned and peak/max current is not characterized at all. I have looked through all documentation and cannot find any document that clearly shows the peak current (I see mention of 300,320,500 mA from the Intern...

MPY for the MIKROELEKTRONIKA CLICKER2

For whom is interested: I have made a board definition for the STM32F407VGT6 based "CLICKER2" board of MikroElektronika and added a small board support package (bsp.py). It can be found under the clicker2 branch of my fork of micropython at @rolandvs. The board features - STM32F407VGT6 mic...
