This is firmware that can be configured and loaded onto an Espressif ESP32-S2 or ESP32-S3 to create a USB mass storage device, whose data is accessed over WiFi via SSH using key authentication. It is based on the LibSSH-ESP32 library.
Sorry, no more upgrades for this system There will not be any further Ubuntu releases for this system's 'i386' architecture. Updates for Ubuntu 18.04 will continue until April 2023.
This guide is for you if you've seen the above message and you want to upgrade your Ubuntu system to 20.04 LTS.
This brief HOWTO shows how to take a working 32 bit 18.04 installation and convert it into a 64 bit system. You will be able to keep all your programs, settings and data. Once converted to 64 bit you can plan the upgrade to 20.04 LTS.
Here is an Arduino library allowing you to write to all flash or EEPROM space with wear leveling. The library already supports multiple memory types (internal EEPROM, I2C and SPI) and can be extended very easily to support others. The memory space can be used as a space to store configuration data with wear leveling, or to read and write (at the same time) sensor data filling the whole memory space efficiently.
A complete Arduino library for the MAX3100 serial UART/USART chip can be downloaded below. There have been many requests for an Arduino library for the MAX3100 external serial USART (UART) chip from Maxim Integrated. As an example of the minor changes needed to use the MAX3100's serial port instead of (or in addition to) the built in serial port, here is some sample code (note the lower case 's' is the only change needed to use the new serial port).
A one stop shop for using the ATMEGA328P standalone at 8MHz or 1MHz clock speed including compiled bootloader. This is for use primarily on a breadboard, but also also directly on, say, a Uno R3 or Nano.
There exists little practical information assisting with the experimentation of '595 shift registers. This article and below Arduino sketch aim to address this vacuum. The sketch simulates one or more (chained) 595 shift registers on the serial monitor while simultaneously driving the IC or ICs via the Arduino's pins. This allows concurrent theoretical and practical experimentation with the 74HC595 first-in-first-out (FIFO) shift register family.
Ready-made QGIS stylesheets (QML) for OpenStreetMap are available for download. These were created and tested with QGIS version 2.2 on Debian GNU/Linux 7.
The relatively new Android mobile cell phone from Doogee called the X6 has its multiple user account capability disabled. The operating system is an old and non-standard Lollipop 5.1 Android, but the multi-user option should still be enabled in a phone of this operating system release. Below are a few simple steps to enable it. A prerequisite is installation of the Android Debug Bridge (ADB)
