How to interface Arduino, esp8266 or esp32 to RS-485
RS-485 work as a broadcast; when you send a message, all devices connected to the wire receive that, so peoples use It is better to implement a lot of protocol to send a message to a specified device or a broadcast address. This article uses regular communication from two devices in a very simple way.
FlatCAM practical tutorial: gcode and PCB milling – Part 6
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing.
Here we are going to create gcode and show the milling process.
FlatCAM practical tutorial: contour – Part 5
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program and create G-Code for Isolation routing.
Here we are going mill contour.
FlatCAM practical tutorial: silkscreen geometry – Part 4
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program and create G-Code for Isolation routing.
Here we are going to add a silkscreen.
FlatCAM practical tutorial: clean non copper area – Part 3
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program and create G-Code for Isolation routing.
Here we are going to remove copper islands.
PCF8574 i2c digital I/O expander: Arduino, esp8266 and esp32, rotary encoder – Part 2
Library to use i2c pcf8574 IC with arduino, esp8266 and esp32.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Here I explain the manage of multiple rotary encoder.
FlatCAM practical tutorial: copper traces geometry – Part 2
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing.
Here tha isolation of traces.
FlatCAM practical tutorial: introduction, installation, and import – Part 1
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing.
Here an introduction, how to install and import files.
FTP server on esp8266 and esp32
For static information (Web pages for examples), that not change frequently, esp8266 or esp32 have internal SPIFFS (SPI Flash File System) and you can upload data via Arduino IDE as explained in the article “WeMos D1 mini (esp8266), integrated SPIFFS Filesystem” but for fast operation and future support It’s usefully use FTP.
