HomeAut project

Description

Welcome in HomeAut project main page.

This document created by Doxygen

HomeAut is a simple demo and "Hardware tester" software, which written in C by Vizi Gábor.

Requirements

Recommended IDE is the Atollic TrueSTUDIO 6.0, but you can use newer or an other IDE.

• Install Atollic TrueSTUDIO
• Install a terminal (serial port reader) software

How to use it?

• Download binaries to your Device
  • If you have source code (project) and an IDE, you can compile and Run/Debug your code on the device
• Start run / Reset device.
• Connect Device to UART-USB converter or other serial converter
  • Connect device UART pins to USB-UART converter (Do not forget the swap: TX-RX):
    • PC6 (TX)
    • PC7 (RX)
    • GND
  • Plug in the UART-USB converter
• Start serial terminal
  • For example:
    • HpyerTerminal
    • PuTTY
    • ZOC
    • FastenTerminal
• Connect Terminal to Serial COM port, with 9600 baudrate, and 8N1 configs
• Type "help" and press enter (send with '\r' or '\n' or together '\r\n')
  • Now, you set "help" command and available commands printed out on terminal
• Enjoy it

Common HW functions

First:

• If you need help, type on terminal:

  help 

• If you can't use a command, type this:

  help <CommandName> 

  • Example:

    help adcread 

For common IO-s:

• Send IO pin initialization command:

  ioinit <port><pin> <input/output> 

  • Example:

    ioinit a1 input  

    or

    ioinit b13 output 

• Send read / write command:
  • Read pin:

    ioin <port><pin> 

    • Example:

      ioin a1 

  • Write pin:

    ioout <port><pin> <set/reset> 

    • Example:

      ioout b13 set 

For ADC-s (Analog-Digital Converter):

• Send command, and you received the last Analog states (voltages):

  adc 

• If you want periodical ADC reading:

  adcread <milliSec> (pin) 

  • milliSec: is the time of period (in millisecond)
  • pin: is the num of pin (1-2-3)
  • Example:

    adcread 1000 

    • Read adc values time of 1 second (1000 millisecond)

For DAC-s (Digital-Analog Converter):

• Note

  Not available in all STM32F4xx!

• Send:

  dac <1/2> <voltage with decimal point> 

  • Example:

    dac 1 3.0 

  • 1. = A4 pin
  • 2. = A5 pin

LED functions:

• Command:

  led <1/2/3> <on/off/toggle/status> 

  • Example:

    led 1 on 

    • 1. LED will set on
  • Example:

    led status 

    • LED statuses will printed out on Terminal
  • Example:

    led green off 

    • Green LED will turn off

How development?

• First, find Vizi Gábor
• Check C language(embedded) tutorials
• Read and check Atollic tutorials
• Download or request HomeAut embedded codes / project
• Develop it, write codes
• Compile
• Debug / Program your device
• Enjoy it
