QUESTION

What microcontrollers don't require a USB to UART driver to interface with computer?

Asked 2021-Mar-22 at 09:43

I am currently teaching a remote middle school summer camp next year that involves microcontroller programming. I’ve chosen to avoid Arduino microcontrollers for the camp and use a MicroPython compatible microcontroller instead. One microcontroller that I am interested in using is the Lolin V 1.1.0 with an ESP-Wroom-32 chip since it is cheap and reliable.

One downside that I’ve noticed with this MCU is that a VCP driver needs to be installed in order to establish a USB to UART connection (It contains a CP210x chip). I’m not too sure how many Operating systems have a VCP driver installed by default. However, I tested to see if the microcontroller was able to be registered on three of my different laptops. On two MacBook airs, my computer was successfully able to locate the MCU without a virtual driver installed. Similarly, I used a Windows computer and a connection was able to be established after 10 minutes (Not sure why it took this long). Finally, I tried it on my friend’s European MacBook and his computer wasn’t able to locate the microcontroller until I installed the driver.

I’m expecting that the camp would be ~300 students and I don’t want anyone to not be able to connect with their Microcontrollers and don’t want to include the installation of the driver since it can be tedious.

Does anyone know how big companies that teach Microcontroller programming to beginners such as MicroBit, Raspberry Pi, or Arduino deal with this problem? How do they ensure that the microcontrollers are read by the computer without having to have students to go through the tedious process of installing a driver?

What percentage of Operating systems have a CP210x VCP driver already installed?

Are there any microcontrollers that don’t require a USB to UART driver installation altogether?

Thanks! Ryan

The only one I am aware of that is pre-installed in windows is microchip PIC (eg PIC16F1454) but a PIC is not the best device for teaching. You have to run an application on the device to use USB VID:PID 04D8:000A.

I don't have a machine to test it but maybe a microchip MCP2200 (04D8:00DF) will be the same.

QUESTION

webUSB api working but the data received aren't decoded properly

Asked 2020-Nov-30 at 14:44

UPDATED CODE

I'm using this code to claim the use of the serial-2-USB device. It shows up and I can query the info about it, ie. "connected to USB2.0-Serial VID: 6790 PID: 29987" (CH34x from Qinheng). To be clear, I use the winUSB driver (downloaded with zadig-2.5.exe, Windows 10) and have uninstalled the original drivers.

I get the received data as dataview but when I do the decode it comes out gibberish. And I see that the array length pretty much corresponds to what I know my ESP8266 is posting over the serial port.

Example of decoded data: �(#��D"D�T�b�!A#7mP�R�N��#�m93aw9 ½�d-K��b��BF+3ѡ��kag1�R�#��#!!r��g�!d��a��谛oa��399�}��1D�#��'99��9��'99��'99��@@譛

I get the data as Uint8Arrays but even if I try to make my own parser the same gibberish is the end result. Do I need to care about USB stuff as in start bits, ack bits etc. etc.? All the example code out there just do a text decoder and that's it.

This isn't a flaw in WebUSB but with the script you are running. The serial.js script included in the Arduino examples repository is designed to work with Arduino devices where setting the baud rate in unnecessary because the port is virtual. In order to set the baud rate on a USB to serial adapter you need to send the SET_LINE_CODING control transfer. This should go before the SET_CONTROL_LINE_STATE command in your existing code. There is documentation for the structure of the control transfer here:

As you can see in the dmesg output:

[ 5.379690] usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60

Looking that up, e.g. here: https://www.google.com/search?q=usb%20vendor%20id%2010c4

Tells you that it's a "Silicon Labs" USB device, who also make the CP2102.

The log does not identify other devices (ignore the linux kernel root hub). So either you have also a CP2102 attached (and the FTDI is not properly connected) or the device you think is a FTDI based device, is not.

In addition you can identify currently enumerated devices using the lsusb command.

The automatic loading is usually done by udev or a similar user space daemon/mechanism. A decent explanation can be found e.g. here: https://lwn.net/Articles/740455/

Unable to install and configure a J-Link JTAG debugger on a Mac

I would suggest to validate your setup step by step - I personally do not like big bang integrations.

Verify that your the Segger software can see your JLink probe - the good thing is that lsusb can see it. JLink Commander should provide some useful information.
Launch openocd without any executable-related arguments: openocd -f interface/jlink.cfg -f board/esp-wroom-32.cfg
Verify that basic commands are working, i.e. resetting the CPU, displaying registers, reading/writing memory.
If you you are still experimenting issues, double-check your wiring - see here for more information.
