### 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

```shell
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:

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

source new profile

```shell
. $HOME/.profile
```

then try to build

```shell
make
```
