:!: Update:

  • Added ymodem module
  • Send or receive files to/from host via same uart on which REPL runs
  • Text or binary files (like images, encoded data, ...) of any size can be sent or received reliably
  • Terminal emulator with support for ymodem protocol must be used (like minicom on Linux or TeraTerm, ExtraPuTTY on Windows)

Code: Select all

>>> import ymodem, uos
>>>
>>> ymodem.recv('image1.bmp')

Receiving file, please start YModem transfer on host ...
(Press "a" to abort)
CCCC
File received, size=230456, original name: "tiger.bmp"

>>> uos.listdir()
['spiffs.info', 'lib', 'boot.py', 'yyy.txt', 'tiger240.jpg', 'tiger.jpg', 'image1.bmp']
>>> uos.stat('image1.bmp')
(32768, 0, 0, 0, 0, 0, 230456, 138, 138, 138)
>>>
>>> ymodem.send('image1.bmp')

Sending file, please start YModem receive on host ...
(Press "a" to abort)
CCC

Transfer complete, 230456 bytes sent
>>>

:!: Update:

  • Some changes needed to build with latest esp-idf commits
  • Master esp-idf archive updated (for non-psRAM builds)
  • improvements in _thread module
    • _thread.start_new_thread() now returns thread id which can be used in some methods
    • added methods suspend(th_id), resume(th_id), stop(th_id)
    • inter-thread notifications:
      • _thread.notify(th_id) send notification to the specific thread
      • _thread.getnotification() check if a notification received from within the thread
    • threads are tested with (relatively) complex modules like uftpserver and works wery well
  • Updated uftpserver frozen module to quietly run in thread
  • other small changes and bug fixes

Thread example:

Code: Select all

  • list & llist methods, list files on server using sftp protocol
  • exec method, execute any command/application on server and get the rusult

Neopixel module

  • uses ESP32 RMT peripheral for precise timing
  • custom timings can be set, any RGB chip can be driven (defaults to WS2812)
  • any color order is supported
  • included methods: clear, set, setHSB, get, show, brightness, HSBtoRGB, RGBtoHSB, timings, color_order

hwI2C module

  • list method, list running/suspended threads to screen or return tuple with threads information

Multiple threads can run smoothly, for example I'm running 5 threads for more than 24h without any problem:

Code: Select all

>>> _thread.list()
ID=1073548004 Name: Neopixel State: running
ID=1073413296 Name: BME280 State: running
ID=1073412568 Name: FTPServer State: running
ID=1073411840 Name: B_Led State: running
ID=1073411360 Name: R_Led State: running
ID=1073454488 Name: MainThread State: running
>>>
[Message from thread "BME280"] [12:02:24] T=26.92C  P=1004.63hPa  H=55.77%
[Message from thread "BME280"] [12:03:32] T=26.89C  P=1004.62hPa  H=55.11%
>>> _thread.notify(npth,1000)
True
>>>
[Message from thread "Neopixel"] [Neopixel] Run counter = 888279
>>>
>>> _thread.suspend(bth)
True
>>> _thread.list()
ID=1073548004 Name: Neopixel State: running
ID=1073413296 Name: BME280 State: running
ID=1073412568 Name: FTPServer State: running
ID=1073411840 Name: B_Led State: suspended
ID=1073411360 Name: R_Led State: running
ID=1073454488 Name: MainThread State: running
>>>

  • B_Led & R_Led blinking leds for 100 ms every second
  • BME280 reading BME280 sensor data using hwI2C and sending inter-thread message to main (repl) thread, accepts notifications for changing/disabling report interval and measure&report on request
  • Neopixel cycling rainbow colors thru 24 WS2812 RGB leds, accepting inter-thread notifications to change brightness and report counter status
  • FTPServer running python FTP server

Repl still runs smoothly, without noticeable effects on other threads even when performing such a task as downloading the file from ftp server.

@loboris :

Thanks a lot for such great work.

i just tried to clone the repository and did a first call to BUILD.sh :

Code: Select all

patrickpollet@patrickpollet-VirtualBox:~/esp32psram/MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD$ ./BUILD.sh menuconfig
unpacking 'esp-idf'
unpacking 'esp-idf_psram'
unpacking 'xtensa-esp32-elf'
unpacking 'xtensa-esp32-elf_psram'

Building MicroPython for ESP32 with esp-idf master branch

DEFCONFIG
/home/patrickpollet/esp32psram/MicroPython_ESP32_psRAM_LoBo/esp-idf/tools/kconfig/conf: 1: /home/patrickpollet/esp32psram/MicroPython_ESP32_psRAM_LoBo/esp-idf/tools/kconfig/conf: Syntax error: ")" unexpected
'make menuconfig' FAILED!




But there was an error, i did a retry and got a different error :

Code: Select all

patrickpollet@patrickpollet-VirtualBox:~/esp32psram/MicroPython_ESP32_psRAM_LoBo/MicroPython_BUILD$ ./BUILD.sh menuconfig

Building MicroPython for ESP32 with esp-idf master branch

MENUCONFIG
/home/patrickpollet/esp32psram/MicroPython_ESP32_psRAM_LoBo/esp-idf/tools/kconfig/mconf: 1: /home/patrickpollet/esp32psram/MicroPython_ESP32_psRAM_LoBo/esp-idf/tools/kconfig/mconf: Syntax error: "(" unexpected
'make menuconfig' FAILED!



I do not know what to do, any help will be really appreciate.

Best regards.

Patrick

@patrick.pollet

It looks like it has something to do with running in virtual machine, but I couldn't reproduce it.
Thes same issue was discussed on GitHub.

:!: Update
Some modules added and updated, many bugfixes and improvements.

Basic documentation added, it will soon be updated to include more detailed documentation for all added/changed modules and features specific to this port.

New implementation of the FTP server is added, it runs in separate ESP32 task, like Telnet server, check the basic documentation for more info.

:!: Update

  • Some bugs in FTP mudule are fixed.
  • New organization of toolchain and esp-idf directories
  • BUILD.sh now checks for toolchain & esp-idf version
  • Building on MacOS is now fully supported, all needed toolchains are included.
    BUILD.sh detects the OS and unpacks the right toolchains for it.
    Tested on MacOS Sierra.

:!: Update:

As of Sep 18, 2017 full support for psRAM is included into esp-idf and xtensa toolchain.

  • Updated esp-idf and xtenssa toolchain to the latest version …
  • Building with psRAM support is now included in main branch
  • No psram parameter is needed for BUILD.sh, just configure psram support in menuconfig
  • Updated MicroPython core to the latest version
  • Buxfixes and improvements in display module, support for ST7735 based displays added
  • Some changes to UART module, tx&rx arguments are now mandatory when creating the UART instance
  • Neopixel module improved, unlimited number of pixels is now supported and less memory is used
  • Other minor bugfixes
  • Bilding on Windows is now fully supported, latest xtensa toolchain for Windows is included
