(Saving...) Getting Started with the STM32F4 and GCC - jeremyherbert.net. Preface Hi. Overview of this guide This guide explains how to get a fully working ARM-GCC toolchain working under Ubuntu Linux, and provides makefiles that are specifically targeted towards the STM32F4 series of microcontrollers. Unfortunately, to load the code on the board, a windows computer (or VM) is needed. I am investigating linux based tools but I am yet to get one working. One important aspect of this guide is that the compiler is built with hardfloat support.
One of the major features of the ARM Cortex-M4 series is the hardware acceleration of floating point operations; however, most free toolchains and compilers don’t provide support for it (you need to cough up some dough for the non-free compiler). Assumed background To follow this guide, you should already know how to navigate and run commands within the linux terminal. . $ apt-get moo means put “apt-get moo” in your favourite terminal software (or any terminal software really…). Stage 1: Build a Toolchain $ . ~/.profile 1. To this: STM32F4 | Benjamin's robotics. Post updated 2015-05-27 Update about this update: There are no assembled ESCs left. However, If you are interested in assembled VESCs you can still send me an email as described below so that I can put you on my extra list. If someone changes their mind or if there are other problems, I can send you VESCs that get left.
I have ordered 100 assembled VESCs and they will arrive this or next week. I don’t need all of them, so I will sell some of them for 115€ + shipping. Worldwide shipping with tracking is 20€ per order (which can contain more than one VESC). I will update this information in the coming days, so make sure to check if there are updates. Because I have made many updates to my custom motor controller recently and the old post is getting confusing with notes and updates, I decided to write a new post about it that hopefully is more clear, more complete and easier to follow. This is an overview of the schematic (download a complete PDF here): This is the front of the PCB: The back: STM32F4 tutorials | Elia's Electronics Blog. Nokia 5110 Display Lib for STM32 GCC | ITead Intelligent Systems Blog. The IFALT32 v2.0 support the Nokia 5110 LCD module, it provide you a inexpensive and simple display options instead of using the ITDB02 TFT LCD module.
Here we release a simple display library for the IFLAT32 with 5110 LCD, it provide you some basic display function. Functions: void LCD5110_init(void) Initial the 5110 LCD hardware, use this function at the top of your mail code. void LCD5110_write_char(unsigned char c) Display one Character on 5110 LCD. void LCD5110_write_char_reg(unsigned char c) Display one Character on 5110 LCD, with inverted color. void LCD5110_clear(void); Clear the screen. void LCD5110_set_XY(unsigned char X,unsigned char Y) Set the display position. void LCD5110_write_string(char *s) Display string. And here is a simple demo code for how to use these functions. Download the library here: Nokia 5110 LCD Display Library for STM32 GCC (3.2 KiB, 480 hits)
