TH7

Seven-channel multiple thermocouple reader and logger HAT for the Raspberry Pi.

This software supports the following thermocouple types:

• B
• E
• J
• K
• N
• R
• S
• T

Features not yet implemented but planned:

• More database logging options than SQLite3
• Advanced filtering, incl. user-selectable filtering stages and sample sizes
• Several logging options at once, one local, one or more remote
• Configure any setting via API call either via RESTful JSON API or GRPC
• A terminal user interface ("TUI") that may be used to remotely monitor/access/configure a TH7 (w/ auth)
• Ability to act in headless mode
• Request dumps from filter stages for noise study
• ... and more!

Note: Most thermocouples that have a coloured and a white lead, usually have the coloured one as the positive.

Building on a Raspberry Pi

This code builds without fuss on Raspberry Pi 4 with go version go1.19.3 linux/arm

wget https://go.dev/dl/go1.19.3.linux-armv6l.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.19.3.linux-armv6l.tar.gz

edit $HOME/.profile and add the following, if not already there:

export PATH=$PATH:/usr/local/go/bin

source new profile

. $HOME/.profile

then try to build

make
