General Usage

Prerequisites

You must have avr-gcc and avrdude installed. To install both tools on a debian-based system, please run the following command:

apt install avr-gcc avrdude

The names for these dependencies may differ for other package managers and distributions. Please check the package sources on your system for more information.

Build and Flash

Run this next command in the project root directory to build and flash the project using an USBasp programmer:

make all

See the Makefile for different settings for your specific build environment. To remove all build related auxiliary files you may run these commands:

make clean
make distclean

You can listen on the serial debug interface using the command below (if you have initialized the optional submodules as described in the next section):

make listen

Temperature and Dewpoint Targets

You can use the script below to send serial commands (you may need to run git submodule update --init if the tools directory is empty):

./opt/tools/serial-send.py <command> <args, ...>

Issue the SET command to update the target settings:

set <temperature> <dewpoint>

Settings are stored in EEPROM and are persistent until a new SET command is issued. Keywords are not case-sensitive. Both arguments may contain a decimal point followed by a sequence of digits.
