Recently, I discovered Platform.io which is a set of tools integrated in Atom editor. It allows the VERY easy management of tool chains for multiple boards. Here is my first program.
This is the code to blink a LED on a GPIO on an ESP8266-1 loaded with NodeMCU. What is of particular interest is the GPIO0 and GPIO2 values. GPIO0=3 GPIO2=4 pin = GPIO0 gpio.mode(pin, gpio.OUTPUT) lighton=0 tmr.alarm(0,1000,1,function() if lighton==0… Continue Reading →
This one of my last prints, a Kryptonian Key [Ecogeeco] inspired from Man of Steel movie. I decided to print it in transparent PLA to allow insertion of a LED.
Today, I’m improving my previous article on RFM12 communication implementing a bidirectional communication between two BugOne boards. To ensure a bidirectional communication is really happening, I’ll be using the code from BugOne’s github project: app_noapp_skel. This project basically takes any… Continue Reading →
Holidays are a good time to make some LED blinking. This time I’m going to do a wireless transmission using RFM12 modules from two BugOne boards.
After my previous article on the MAX6969, I’m investigating the reason of the strange visual artifacts on LEDs when changing data.
Today I decided to take the MAX6969 sample a step further using Pulse Width Modulation (PWM) to vary LEDs intensity.
