Re: ESP32FLASHWRITER

It seems that module termios is not available on Windows: "Because it requires the termios module, it will work only on Unix." https://docs.python.org/3/library/tty.html I have improved the Linux version to get it to work with Windows 10 and fixed other bugs. I have updated repository https://githu...

Re: ESP32FLASHWRITER

Is it possible to build portable executable for Windows with all dependencies included? I do not have the experience. However, I do hope to be able to try my script on Win OS some time soon. If things work out, I will then update my python script in the repository. I think work to build portable ex...

ESP32FLASHWRITER

https://github.com/sunbearc22/ESP32FlashWriter.

I wrote this simple to use GUI to connect to a ESP32 device and write firmware to the esp32 flash. I like to share it here and seek your feedback and advice on its use. Thank you. ;)

Re: How to copy files (e.g. .py, .txt, .dat) to and from the esp32 flash?

@Roberthh, can you elaborate on what you mean? E.g. what do mean with write data to place where the file system starts ? In my example, I had thought the FAT32 filesystem started from 0x0 to end of the flash, consisted of one partition, with micropython occupying 0x1000 to say 0x109800. Thereafter, ...

Re: How to copy files (e.g. .py, .txt, .dat) to and from the esp32 flash?

Thanks. I was experimenting using `esptool.py` to copy a .py file into flash. For example, after installing micropython with : esptool.py --chip esp32 --port /dev/ttyUSB0 write_flash -z --erase-all --compress 0x1000 firmwares/esp32-20190125-v1.10.bin esptool.py v2.6 Serial port /dev/ttyUSB0 Connecti...

How to copy files (e.g. .py, .txt, .dat) to and from the esp32 flash?

How can the above be achieved from a Linux system? Purpose: copy python modules and data files into and out from the flash? Thanks.

Re: How do I terminate a background program/thread/function/method in uPy?

I came across this https://www.freertos.org/a00021.html#vTaskList. Are these task utilities exposed in any uPy module that a user can use on an esp32?

@pythoncoder Thanks for the "tips".

Re: How do I terminate a background program/thread/function/method in uPy?

I was running uPy on esp32 devkit v1 with no SD card. Any "trick" for this? ;)

Will pulling out the SD-card for your system reduce the life-span of the card?

How do I terminate a background program/thread/function/method in uPy?

I was running the Basic WiFi configuration script provided in help(). Unfortunately, I did a typo in one of the args for the .connect() method. Thereafter, my terminal was flooded with the family of msgs relating to "wifi: STA_DISCONNECTED, reason:15" which I understand it to mean "15 4-Way Handshak...
