# How to contribute
Thank you for your interest in improving the TinyGo drivers.
We would like your help to make this project better, so we appreciate any contributions. See if one of the following descriptions matches your situation:
### New to TinyGo
We'd love to get your feedback on getting started with TinyGo. Run into any difficulty, confusion, or anything else? You are not alone. We want to know about your experience, so we can help the next people. Please open a Github issue with your questions, or you can also get in touch directly with us on our Slack channel at [https://gophers.slack.com/messages/CDJD3SUP6](https://gophers.slack.com/messages/CDJD3SUP6).
### One of the TinyGo drivers is not working as you expect
Please open a Github issue with your problem, and we will be happy to assist.
### Some specific hardware you want to use does not appear to be in the TinyGo drivers
We probably have not implemented it yet. Your contribution adding the hardware support to TinyGo would be greatly appreciated.
Please first open a Github issue. We want to help, and also make sure that there is no duplications of efforts. Sometimes what you need is already being worked on by someone else.
## How to use our Github repository
The `release` branch of this repo will always have the latest released version of the TinyGo drivers. All of the active development work for the next release will take place in the `dev` branch. The TinyGo drivers will use semantic versioning and will create a tag/release for each release.
Here is how to contribute back some code or documentation:
- Fork repo
- Create a feature branch off of the `dev` branch
- Make some useful change
- Make sure the tests still pass
- Submit a pull request against the `dev` branch.
- Be kind
## How to run tests
To run the tests:
```
make test
```

# TinyGo Drivers
[![PkgGoDev](https://pkg.go.dev/badge/tinygo.org/x/drivers)](https://pkg.go.dev/tinygo.org/x/drivers) [![CircleCI](https://circleci.com/gh/tinygo-org/drivers/tree/dev.svg?style=svg)](https://circleci.com/gh/tinygo-org/drivers/tree/dev)
This package provides a collection of hardware drivers for devices such as sensors and displays that can be used together with [TinyGo](https://tinygo.org).
## Installing
```shell
go get tinygo.org/x/drivers
```
## How to use
Here is an example in TinyGo that uses the BMP180 digital barometer:
```go
package main
import (
"time"
"machine"
"tinygo.org/x/drivers/bmp180"
)
func main() {
machine.I2C0.Configure(machine.I2CConfig{})
sensor := bmp180.New(machine.I2C0)
sensor.Configure()
connected := sensor.Connected()
if !connected {
println("BMP180 not detected")
return
}
println("BMP180 detected")
for {
temp, _ := sensor.ReadTemperature()
println("Temperature:", float32(temp)/1000, "°C")
pressure, _ := sensor.ReadPressure()
println("Pressure", float32(pressure)/100000, "hPa")
time.Sleep(2 * time.Second)
}
}
```

# ESP-AT Driver
This package provides a driver to use a separate connected WiFi processor either the ESP8266 or the ESP32 from Espressif.
The way this driver works is by using the UART interface to communicate with the WiFi chip using the Espressif AT command set.
## ESP-AT Firmware Installation
In order to use this driver, you must have the ESP-AT firmware installed on the ESP8266/ESP32 chip.
### Installing on Arduino Nano33 IoT
In order to install the needed firmware on the Arduino Nano33 IoT board's built-in NINA W102 chip, you will need to use the `arduino-nano33-iot` branch of this fork of the firmware:
https://github.com/hybridgroup/esp32-at
To flash this firmware on the Arduino Nano33 IoT you will need to follow the following procedure:
- Install _Arduino SAMD Boards_ from the Boards Manager.
- Install _WiFiNANO_ from the Library Manager.
- Using the normal Arduino software, load the `SerialNINAPassthrough` sketch on to the board (in File -> Examples -> WiFiNINA-> Tools).
- Flash the NINA 102 firmware using the `make flash` command in the https://github.com/hybridgroup/esp32-at repo.
You only need to do this one time, and then the correct ESP-AT firmware will be on the NINA chip, and you can just flash the Arduino Nano33 IoT board using TinyGo. We should be able to remove some of these step in a future release of this software.
### Installing on ESP32
The official repository for the ESP-AT for the ESP32 processor is located here:
https://github.com/espressif/esp32-at
Your best option is to follow the instructions in the official repo.
### Installing on ESP8266
The official repository for the AT command set firmware for the ESP8266 processor is located here:
https://github.com/espressif/ESP8266_NONOS_SDK
First clone the repo:
```shell
git clone https://github.com/espressif/ESP8266_NONOS_SDK.git
```
You will also need to install the Espressif `esptool` to flash this firmware on your ESP8266:
https://github.com/espressif/esptool
Once you have obtained the binary code, and installed `esptool`, you can flash the ESP8266.
Here is an example shell script that flashes a Wemos D1 Mini board:
```python
#!/bin/sh
SPToolDir="$HOME/.local/lib/python2.7/site-packages"
FirmwareDir="$HOME/Development/ESP8266_NONOS_SDK"
cd "$SPToolDir"
port=/dev/ttyUSB0
if [ ! -c $port ]; then
port=/dev/ttyUSB0
fi
if [ ! -c $port ]; then
echo "No device appears to be plugged in. Stopping."
fi
printf "Writing AT firmware to the Wemos D1 Mini in 3..."
sleep 1; printf "2..."
sleep 1; printf "1..."
sleep 1; echo "done."
echo "Erasing the flash first"
esptool.py --port $port erase_flash
esptool.py --port /dev/ttyUSB0 --baud 115200 \
write_flash -fm dio -ff 20m -fs detect \
0x0000 "$FirmwareDir/bin/boot_v1.7.bin" \
0x01000 "$FirmwareDir/bin/at/512+512/user1.1024.new.2.bin" \
0x3fc000 "$FirmwareDir/bin/esp_init_data_default_v05.bin" \
0x7e000 "$FirmwareDir/bin/blank.bin" \
0x3fe000 "$FirmwareDir/bin/blank.bin"
echo "Check the boot by typing: miniterm $port 74800"
echo " and then resetting. Use Ctrl-] to quit miniterm."
```
