Library 54- General library for STM32F4xx devices 5

Library 54- General library for STM32F4xx devices

For 54th lib I decided to make it’s name to be “General”. With this name I mean that in this library, a lot of different stuff, maybe unrelated between, but very useful things will be implemented. It allows you to make software reset, get reset source, disable or enable global interrupts (NVIC) and more. It will be updated frequently but for now it’s just a start to use it in your projects. Library Features Support for software reset with callback...

LwIP ethernet on STM32F4-Discovery 204

Library 52- Ethernet peripheral on STM32F4xx

One of the greatest features on STM32F4xx for me was to get ethernet to work properly as server and client. I got it working pretty quickly and I was investigating how to make a library to be very useful and easy to use. Ethernet library is built on LwIP TCP/IP stack version 1.4.1. Library is pretty hard to “install” for first time, so I decided to provide you source files (on my Github) for Keil uVision and Coocox. Examples for Keil...

Library 33- PWM for STM32F4

I had enough of each time configuring PWM for some reason, so I decided to make a library for it. This library allows you to use PWM signal on all possible timers on all possible pins for timer. I made it for controling servos, but it can be used for anything else. PWM works in FAST PWM mode. You just set your PWM frequency, timer you will use, channel on timer and you are ready to go. If you need...

ILI9341 Button library for STM32F4 52

Library 11- Button library for ILI9341 LCD and STMPE811 touch controller on STM32F429 Discovery board

Now we have both, LCD controller and touch controller configured and we can use this. For this purpose i made a library for buttons. This library can draw buttons on LCD and check if touch has been pressed on any enabled button. Library Features Set X and Y location of button Set button’s width and height By default 10 buttons are supported Use labels Custom background image or color Border around button Selectable font Disable/Enable button Selectable color for label,...
