Arduino generating two fast phase offset signals

So recently I wanted to generate two fast (40kHz), phase offset signals with Arduino. I have done various modes of PWM and PPM modulation before, but have not yet tried to generate phase offset signals. Actually there is only one

Using and programming a NEO-6 GPS receiver module

I recently had to programm a NEO-6 GPS receiver module for a friend of mine, that needed it to have a specific baudrate and specific NMEA sentences to be sent. The module was to be connected to a ham radio

USB to serial (TTL/RS232) converter comparison

There are many integrated circuit products available for the USB to serial (TTL or RS232) conversion on the market. Serial communication protocols like RS232, RS485, RS422, USART, UART, LIN are still commonly used in industrial and commercial applications where only

ESP8266 update firmware to change the baudrate

So today I figured I could update firmware on my ESP8266 to make it useful for work with the arduino uno. The problem with the original firmware is that the serial port baudrate is fixed at 115200 which is way

Changing FTDI PID

There is a big fuss about the new FTDI driver which damaged many counterfeit FTDI chips (well, it actually changed their internal configuration rendering them useless to most people). This didn’t hurt the producer of the counterfeit chips, however made

USR-WIFI232 wifi to serial module (HF-LPT100)

I have bought a USR-WIFI232-T module, which seems to be identical to HF-LPT100. The main chip is marked with HF so the High Flying may be the original producer. The module is only 22 x 13,5 x 6mm in size and

Install arduino driver on Windows 8

Lol, actually Arduino beat me in releasing a properly signed driver before I published this article. I tested it and it works like a charm – no workarounds needed, just download the latest Arduino IDE release and install the  included

Install USBASP programmer on Windows 8

I have the following programmer (a chinese clone actually, however it is equivalent): http://www.fischl.de/usbasp/   I have happily used it on my older WinXP computer, but as that computer has been retired I came across a problem of installing it

CH340 Arduino performance

There have been many low-cost Arduino boards with CH340 converter available recently. CH340 is a USB to UART/TTL converter made by WCH (Win Chip Head ? / www.wch.cn / www.wch-ic.com). The converter replaces the costlier FT232 / PL2303 / CP2102

Arduino IDE working slow and how to speed it up

I have been doing some work in Arduino IDE on an old laptop I have been using for field work. Arduino worked painfully slow (eg. opening menus blocked any work for almost 20 seconds), but I didn’t think that the
