ESP8266 10-Base-T Ethernet Driver

Overall Discussion This is a relatively unreliable and coincidentally functional ESP8266 Ethernet driver. It only uses two pins on the ESP, the I2S pins, but does provide Ethernet. It does all its own manchester encoding/decoding, framing, FCS, etc. It mimics the ENC424J600 stack found in avrcraft and borrows the IP, ARP, UDP and TCP stacks from that project, too. This product was created by Charles Lohr, b ...

4A Bipolar Stepper Motor Driver Based on LV8727E

The Project is based on LV8727E IC from ON Semiconductor. The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can provide eight ways of micro step resolution of 1/2, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20, and can drive simply by the step input. This Bipolar Driver works with supply input 9V to 36V (Replace L317 with L317HVT for supply input up to 45V DC). Load cur ...

USB Interface Board Driver Installation PIC18F4550

USB Interface Board Driver Installation Connecting PIC18F4550 First Time This tutorial will try to explain how to make your interface development board to work for the first time. Without a Demo hex code inside PIC18F4550's flash memory, it  won’t respond even if we connect the Demo Interface Board Directly to computer. In my previous post we have successfully loaded the Demo Hex Code into the PIC18F4550  u ...

RGB LED PWM Driver for High Power 350mA LEDs V3 using PIC12F629

Description As featured in Electronics Weekly Gadget Freak (20/02/2008) The main reason I made this version is that I wanted to fit it in to the base of an Ikea Mylonit lamp. This lamp is made entirely from glass and has a small recess in the base with an entry for the power lead.  Since it had nowhere to fit a separate power connector but did have a slot for a power lead to pass in to the base, I needed to ...
