Introduction It’s been so long since I had the idea for this project that I can’t remember why I had the idea in the first place. At least I blame it on the passage of time although this engineer is getting on a bit now so it could easily be memory rot on my part. So here we are then, a reflow oven controller. Let’s quickly recap what a reflow oven is for those that are new around here. The two main processes used in industry to build printed circuit boards are wave soldering and reflow using a very large industrial oven that you probably can’t afford and if you could afford to buy it you probably couldn’t...
The KSZ8051MLL Ethernet PHY revisited
posted by Andy
It’s been more than a year now since I brought you my design for an ethernet PHY based on the Micrel KSZ8051MLL. The design was an unqualified success and I’ve been using it successfully with both the STM32F107 and the STM32F4 series MCUs coupled to the TCP/IP stack that I wrote...
stm32plus 3.2.0: Supporting the STM32F0 Cortex M0
posted by Andy
A few months ago I made the decision to start supporting the lower priced, hobbyist friendly STM32 devices in my stm32plus C++ library. These lower-end devices come in lower pin-count, smaller packages that are easier to work with and they have reduced clock speeds that make for fewer PCB...
stm32plus 3.1.1: Supporting the STM32 VL Discovery
posted by Andy
If you’ve been following the releases on my stm32plus github repo then you’ll already be aware that version 3.1.1 has been released. The main feature of this new release is support for the STM32 Medium Density Value Line devices, exemplified by the STM32 Value Line Discovery board...

Welcome to another in my series of cellphone LCD reverse-engineering articles. In this article I’m going to present everything you need to hook up the high-resolution 640×360 LCD from the Sony Ericsson U5 Vivaz to your project. About the phone and LCD The Sony Ericsson U5 Vivaz LCD...
Reverse engineering the LG KF700 480 x 240 widescreen cellphone LCD
posted by Andy
Hello and welcome to my first published non-Nokia cellphone LCD reverse-engineering effort. All my articles in this series focus on bringing you all of the details that you would need in order to connect a low-cost cellphone LCD to an MCU for use in your own projects. This one is no different. I will explain the pinout and the signals. I will tell you about the connector and where you can buy it and I will tell you about the controller IC and of course I will give away the complete source code driver for that controller. Let’s get started. The LG KF700 The KF700 was released in 2008 and is now a discontinued model. It featured a 3.0...
stm32plus::net, a C++ TCP/IP stack for the STM32
posted by Andy
Welcome to a landmark release, version 3.0.0, of my stm32plus C++ library for the STM32F1 and STM32F4 series of microcontrollers. This release introduces support for the ethernet MAC peripheral in the form of an object-oriented TCP/IP stack as well as support for the STM32F107 connectivity...
stm32plus 2.1.0
posted by Andy
The latest release is now 3.0.0. Be sure to check out the announcement here. Due to the use of c++0x features the minimum compiler requirement is now version 4.7.0 of gcc stm32plus version 2.1.0 has now been released and is available from my downloads page. This article will...
