uzlib and lwip

While looking at a project evolving STM32 collecting data, compressing the data, sending the data using UDP I wanted to read up on the functions: uzlib only decompresses and there is no documentation on lwip for micropython. I did find the source for uzlib and lwip, is there a reason not to add comp...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

It took me awhile to figure out how to get the function to run: DAC1 DAC2 LED_D1 LED_D2 OSC32_IN OSC32_OUT PA0 PA1 PA10 PA11 PA12 PA13 PA14 PA15 PA2 PA3 PA4 PA5 PA6 PA7 PA8 PA9 PB0 PB1 PB10 PB11 PB12 PB13 PB14 PB15 PB2 PB3 PB4 PB5 PB6 PB7 PB8 PB9 PC0 PC1 PC10 PC11 PC12 PC13 PC14 PC15 PC2 PC3 PC4 PC5...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Features that are already working SD card, NRF24, RTC, Flash, EEPROM, Buttons, LEDs, I2C, SPI, ADC, DAC, etc. I'm keen to get the ILI9341 TFT working (in parallel mode) with touch and SRAM. I can blink LED(1) and LED(2) but that is it. I found a SDtest.py script but it bombs on: sd = sdcard.SDCard(...

Re: Can't Save main.py

Finally! The import foo.py works with a Ctrl+C to kill the code. Edit on local PC drive then copy foo.py to the micropython drive and in putty terminal import foo.py runs the code without ejecting the drive and hitting reset! The whole edit main.py burned some time as the editors really don't like t...

These are 100mb each and I believe the graphics are there.
The other site had phpBBS .htaccess killing everything.

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

After finding the STM32F407XXX boards I started looking for the software they used and came across "core.zip" that has all the Keil source. I don't have the Keil compiler but found Keil2GCC.exe. I converted all the core.zip (40 or more subdirectories of code) to GCC projects. (1) Template (10) Input...

Re: ImportError: No module named usb.core

It seems the BLACK_F4 are all using F405 linker and AF definitions except the ZG board, I change that to match the ZE board since the ZE was using the 1MB flash F405 linker code.... which includes ethernet for F405 devices, someday I'll spend the time to figure that out. D407ZG now works!

Re: ImportError: No module named usb.core

Did that but another issue, my Windows 10 hosted linux has no lsusb devices! ( Found: In Windows Insider build #16176 WSL now allows access to serial devices (COM ports).) $ make BOARD=BLACK_F407ZE deploy Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

ImportError: No module named usb.core

While discovering MicroPython I updated my stm32f4-discovery with a pre-built DFU image I found, works great. My next attempt was at building an image for the BLACK_F407VE/ZE/ZG boards I've had laying around collecting dust (Pet rocks). Installed Ubuntu 16.04 on Windows 10 and followed the guide to ...

Install issues, maybe

Following along with the install on Github I bombed on the final make: $ make V=1 python ../../py/makeversionhdr.py build/genhdr/mpversion.h make: python: Command not found ../../py/py.mk:278: recipe for target 'build/genhdr/mpversion.h' failed make: *** [build/genhdr/mpversion.h] Error 127 If I ent...
