how to attach a USB device to ubuntu 20 running on WSL

 This article will tackle the steps needed to attach a usb device to ubuntu through WSL on windows 10 

for this tutorial you will nedd 

- Ubuntu 20.xx on wsl2 

- mobixterm 

to start the process you need to run ubuntu 

and type the following on your terminal 


pc:~$ sudo apt install linux-tools-5.4.0-77-generic hwdata
pc:~$ sudo update-alternatives --install /usr/local/bin/usbip usbip /usr/lib/linux-tools/5.4.0-77-generic/usbip 20


Attaching a device

First ensure a WSL command prompt is open. This will keep the WSL 2 lightweight VM active.

From an administrator command prompt on Windows, run this command. It will list all the USB devices connected to Windows.

pc:cmdadmin>  usbipd wsl list


Select the bus ID of the device you’d like to attach to WSL and run this command. You’ll be prompted by WSL for a password to run a sudo command.

pc:cmdadmin> usbipd wsl attach --busid <busid>


From within WSL, run lsusb to list the attached USB devices. You should see the device you just attached and be able to interact with it using normal Linux tools. Note that depending on your application, you may need to configure udev rules to allow non-root users to access the device.

Once you are done using the device in WSL, you can either physically disconnect the device or run this command from an administrator command prompt on Windows.

pc:cmdadmin> usbipd wsl detach --busid <busid>
it is possible for the USB not to work due to rules issue for example if you want to link serial communicaiton with ubuntu 

in this case its posible to use this command 

 

pc:~$ ls /dev/tty* | grep USB
 

pc:~$ sudo chown user: /dev/ttyUSB0

What is the ESP32 VSPI / HSPI

 The ESP32 integrates four SPI peripherals. SPI0 and SPI1 are used to access the ESP32’s attached flash memory and thus are currently not open to users to be used . They share one signal bus via an arbiter. SPI2 and SPI3 are general purpose SPI controllers, sometimes referred to as HSPI and VSPI, respectively. They are open for use. SPI2 and SPI3 have independent signal buses with the same respective names. Each bus has three CS lines to drive up to three SPI slaves.

Most common baud rates table

  The following table shows the most used baud rates. The left side part of the table shows speed and bit duration. The right part shows real transmission speed assuming there is no parity, 8 data bits and one stop bit.   Bauds Bits/s Bit duration Speed Actual speed Actual byte duration 50 bauds 50 bits/s 20.000 ms 6.25 bytes/s 5 bytes/s 200.000 ms 75 bauds 75 bits/s 13.333 ms 9.375 bytes/s 7.5 bytes/s 133.333 ms 110 bauds 110 bits/s 9.091 ms 13.75 bytes/s 11 bytes/s 90.909 ms 134 bauds 134 bits/s 7.463 ms 16.75 bytes/s 13.4 bytes/s 74.627 ms 150 bauds 150 bits/s 6.667 ms 18.75 bytes/s 15 bytes/s 66.667 ms 200 bauds 200 bits/s 5.000 ms 25 bytes/s 20 bytes/s 50.000 ms 300 bauds 300 bits/s 3.333 ms 37.5 bytes/s 30 bytes/s 33.333 ms 600 bauds 600 bits/s 1.667 ms 75 bytes/s 60 bytes/s 16.667 ms 1200 bauds 1200 bits/s 833.333 µs 150 bytes/s 120 bytes/s 8.333 ms 1800 bauds 1800 bits/s 555.556 µs 225...

How to program 8051 based MCU using Ptroteous Schematic capture and Source code editor to use timers using AT892051 + project files

 This tutorial is dedicated to use a 8051 based Microcontroller core and program it using keil's C51 tools on the Proteus Source code editor.  1- Brief History of 8051 one of the first microprocessors 4004 was invented by Intel Corporation as well as  8085 and 8086 microprocessors back in 1981,shortly after Intel introduced an 8-bit microcontroller called the 8051 . It was referred to as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip. When it became so widespread, Intel allowed other manufacturers to make and market different flavors of 8051 with its code compatible with 8051. It means that if you write your program for one flavor of 8051, it will run on other flavors too, regardless of the manufacturer. This has led to several versions with different speeds and amounts of on-chip RAM. 2- Features of AT892051 Microcontroller Compatible with MCS®-51Products 2K ...
