OregonPico

433 Sensor Oregon Scientific decoder for Raspberry Pico

This example uses a rxb6 receiver, and a Raspberry Pi 3 for code transfer and serial output.

To compile this project, you will first need to follow Chapter 2 of the official Pico guide

Layout should be as follows:

~/pico/pico-sdk/
~/pico/OregonPico/

Create a new build dir inside this repo:

mkdir ~/pico/OregonPico/build

Change into the directory and run the following:

export PICO_SDK_PATH=../../pico-sdk
cmake ..
make

This will create the test.elf file below.

To deploy this using SWD and monitor using minicom, run the following once you have wired everything up as below.

Start following in a terminal:

openocd -f interface/raspberrypi-swd.cfg -f target/rp2040.cfg

Also start minicom to listen for output in a new terminal:

minicom -b 115200 -o -D /dev/serial0

Enter gdb and load file:

gdb-multiarch test.elf
target remote localhost:3333
load
monitor reset init
continue

In the minicom terminal window you should see something similar to the following output:

OSV3 FA281493800690C956B5
Temp : 12.800000
Humidity : 98.000000
Channel : 1
OSV3 FA281493800690C956B5
Temp : 12.800000
Humidity : 98.000000
Channel : 1

Pimatic Integration

You can use it with pimatic-log-reader as I do :)

https://pimatic.org/plugins/pimatic-log-reader/

pimatic config example:

{
  "id": "oregon1",
  "name": "Bedroom Sensor",    //sensor display name
  "class": "LogWatcher",
  "file": "/home/pi/OregonPi/log_oregon.csv",  //log file
  "attributes": [
    {
      "name": "temp",
      "type": "number",
      "unit": "°C"
    },
    {
      "name": "hum",
      "type": "number",
      "unit": "%"
    }
  ],
  "lines": [
    {
      "match": "1,temp(.+),hum(.+)",   // ->1<- Sensor channel number
      "temp": "$1",
      "hum": "$2"
    }
  ]
}
