Beyond .NET

Endpoint's hardware and documentation's main focus is .NET, however the system is capable of supporting other languages as well.

Python

Getting Started

Install the latest version VS Code, https://code.visualstudio.com/

Visit the extension section from within VS Code and search for and install Endpoint VSC Python Debugger. Alternatively, Download and install the latest Endpoint VSC Python Extension (.vsix) file manually.

Navigate to View -> Command Palette

Command Palette

Search for Endpoint and select Endpoint:Create Python project

Search Endpoint

Give the project a name and location.

Tip

If you change the default project name you must also change it in the settings.json file

Python Libraries

Endpoint uses the standard Python libraries when available. When a library doesn't existing inside the Python API relating to embedded hardware we use an Endpoint library to fill in the missing gaps. Additional libraries are under development.


Peripheral	Endpoint Python Library

GPIO	GHIElectronics.Endpoint.Core.EPM815.Gpio
PWM	GHIElectronics.Endpoint.Core.EPM815.PWM
SPI	GHIElectronics.Endpoint.Core.EPM815.Spi
I2C	GHIElectronics.Endpoint.Core.EPM815.Adc
ADC	GHIElectronics.Endpoint.Core.EPM815.Adc
DISPLAY	GHIElectronics.Endpoint.Core.EPM815.Display
RTC	GHIElectronics.Endpoint.Core.EPM815.RTC
Register	GHIElectronics.Endpoint.Core.EPM815.Register
Serial Port	GHIElectronics.Endpoint.Core.EPM815.SerialPort

The Python libraries are built into the release image, user don't need to do anything else, just use import.

This uses remote debug, so there is no IntelliSense built in. Optionally users can install on the PC to use IntelliSense when importing the libraries.

C:\pip install GHIElectronics.Endpoint.Core

After install, VSC code IntelliSense will show the libraries available.

Python Code Samples

Here is a couple code samples to get started.

Additional code samples can be found in the Endpoint Samples Repo

Python GPIO

The code sample below blinks an on-board LED.

import gpiod
import time
import GHIElectronics.Endpoint.Core.EPM815.Gpio as Gpio
 
pin = Gpio.Pin.PC0 
chip=gpiod.Chip(str(int(pin / 16)))
line = chip.get_line(pin % 16)
line.request(consumer='test', type=gpiod.LINE_REQ_DIR_OUT)
 
while True:
    line.set_value(1)
    time.sleep(0.5)
    line.set_value(0)
    time.sleep(0.5)

Python PWM

The code sample demonstrates PWM using an on-board buzzer.

import time
import GHIElectronics.Endpoint.Core.EPM815.G as Pwm

pwm = Pwm.PwmController(Pwm.Pin.PF9)

pwm.Frequency = 1000
pwm.DutyCycle = 0.5
pwm.Start()
time.sleep(3)
pwm.Stop()
