connecting to esp32 board

[loboris]

I'm trying to connect to ESP32 board (SparkFun ESP32 Thing) with Lua RTOS for ESP32, but with no success. blockly-environment installed on Google Chrome (as application). Tested on Linux (Ubuntu 16.10) and Windows 10. The board itself works, tested with minicom on Ubuntu.

Please, send me the device name for your UART connection when you connect your board:

/dev/ttyXXXXXXX .....

[loboris]

/dev/ttyUSB0

Were you able to get your ESP32 Thing connected to the blocky-environment? I am trying to do so also, but from windows 8.1. The thing is using a FTDI usb to serial converter.

This project is being migrated to nw.js because Chrome Apps will be discontinued by google in 2017 (see https://blog.chromium.org/2016/08/from-chrome-apps-to-web.html).

I hope that source code will be available by the end of this week in this repository.

Thanks for your patience.

First version for nw.js version is available for windows and mac on this repository.

Please, read https://github.com/whitecatboard/blockly-environment/wiki/First-Steps for instructions.

Adapter information for "CP210x USB to UART Bridge Controller" is available in this version. This corresponds to the adapter present in our test board. We don't have any ESP32 Thing for test.

If you can't connect your board to the blockly environment follow the following instructions:

In app menu you have Settings --> Adapters:

• "List serial port adapters" option shows the connected serial port adapters in your computer. For each adapter you can view the path and displayName for the adapter. This information is needed for configure a new adapter in case that your board is not detected.

• Select "Settings --> Adapters --> Silicon Labs". A window will be opened for edit this adapter.

• Click on "Save As" button, and enter the name for the new adapter information without any extension.

• Edit for feet your board. "path" and "displayName" are regular expressions. Enter a regular expression for each that match path and displayName listed in "List serial port adapters" option.

• Click on "Save" button.

• When saved the Blockly Environment will be restarted, and if things are ok your board will be detected.

If works, please send to us the adapter configuration.

NOTE:

The Blockly Environment needs a board with a Lua RTOS firmware, and the serial adapter connected to the DTS and RTS lines.

In Windows I can connect to the board (ESP32 Thing), but only first time after flashing if the board stays in bootloader. ESP32 Thing has DTR connected to CHIP_PU (rst/en) not DTS, same as on ESP32-DEVC (!), RTS is connected to IO0. esp32-thing-schematic.pdf FTDI adapter: Device Name "USB Serial Port", port: COM3

Under Linux, I can't connet to the port, even the first time after flashing. Device Name: "FT231X_USB_UART", port: "/dev/ttyUSB0"

Thanks for the schematic. There are an error in my last comment: the board need to have the serial adapter connected to the DTR and RTS lines (not DTR and DTS).

Please, try the following:

• Edit boards/board.js

• Search for "setControlSignals"

• The reset of the board are done by:

  chrome.serial.setControlSignals(port.connId, { dtr: true, rts: true }, function() { chrome.serial.setControlSignals(port.connId, { dtr: false, rts: false }, function() {

• Try to change with:

  chrome.serial.setControlSignals(port.connId, { dtr: false, rts: true }, function() { chrome.serial.setControlSignals(port.connId, { dtr: false, rts: false }, function() {

• The thing is that playing with dtr and rts values you must generate a reset pulse on CHIP_PU

We are analyzing a method to perform a boar reset based on the board configuration, and preserve the plug & play method (We do not want the programmer to have to select the board type).

Please, retry with this commit (https://github.com/whitecatboard/blockly-environment/commit/0714b70ab71e9c9d5c7971a4893deae2ad225797).

I have tried to buy a ESP32 thing, but is out of stock!

:(

I am able to connect to my ESP32 Thing using the instructions above. I am so new to I am trying out what to do next. Thanks

[loboris]

I can confirm that I can connect To my ESP32 Thing with the latest commit. Tested under Linux. I get one error on start: [23261:23261:0110/083848:ERROR:desktop_window_tree_host_x11.cc(1131)] Not implemented reached in virtual void views::DesktopWindowTreeHostX11::InitModalType(ui::ModalType) but everything works. I haven't built the app, started with nw ./src

[jolivepetrus]

Yes, when you start with nw ./src, some errors are prompt to the console. This errors com from the Blockly's core implementation.

We have plans for upgrade to last Blockly version in the next weeks.

Hi @loboris,

The Whitecat IDE is now available on the web in alpha version. For windows you need:

• Download this: https://whitecatboard.org/downloads/windows.zip

• Uncompress an install

• Go to the installation folder an run the exe file

• This is The Whitecat Create Agent, a small piece of software that allows the communication between the IDE and your board using a serial connection

• Open a session in Google Chrome

• Go to https://ide.whitecatboard.org

• Sign in using your Google's Account

Yo have 2 programming models: blocks or lua. If you are in blocks you can switch to Lua pressing the ";" button in the toolbar. If you want switch to blocks press the "puzzle" button in the toolbar.

In the next weeks we have plans for document all and create the wiki!

Best regards,

Jaume
