Install VS Code

dang@dang-laptop ~$ sudo pacman -S code

And Start the code program

In the Editor:

• Select Extensions (Box looking thing on the RHS)
• Platformio-ide
• Install

Click Reload wait till installed and click reload again

It appears that platformIO installs in a virtualenv somewhere, Very nice

Arduino Project

Should be quick and easy to do.

New Project -> Select UNO Board -> Rest is default

Navigate to the Code folder src/main.cpp

Teh Codez

Edit the code to be something like

#include <Arduino.h>

int LED=13;


void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(LED, OUTPUT);
  }

void loop() {
  // put your main code here, to run repeatedly:

  Serial.print("Tick....");
  digitalWrite(PIN, HIGH);
  delay(500);

  Serial.println("Tock");
  digitalWrite(PIN, LOW);
  delay(500);
  }

Compiling and Uploading

• Use the Build Button on the toolbar at the bottom of the page
• Use the Upload Button on the toolbar

MBED Project

Create a new project as before but select the relevant Target Board

Code is

#include <mbed.h>

DigitalOut myled(LED1);

int main() {

  // put your setup code here, to run once:

  while(1) {
    // put your main code here, to run repeatedly:
    myled = 1;
    wait(1);
    myled = 0;
    wait(1);
  }
}

To Upload we need to mount the device again but then it works without a flaw

Multiple Targets

I also have an old skool NXP LPC

https://docs.platformio.org/en/latest/boards/nxplpc/lpc1768.html

[env:lpc1768]
platform = nxplpc
board = lpc1768

Upload and it works (after a reset)

One Issue is it builds and tries to upload both tasks We can fix this by selecting the task required, using the run task (tickbox) option on the menu.

Trying moving things from the Sim

In the MBED simulator they have a nice LCD demo

http://ec2-52-211-146-247.eu-west-1.compute.amazonaws.com:7829/#lcd

Copy and paste the code into vscode

Install external library

To get the LCD working we need an external Library

Click Platform IO Home, and the Install Libraries

Search for C12832

Install it

Fix the Lookup for the SPI

C12832 lcd(p5, p7, p6, p8, p11);
//C12832 lcd(SPI_MOSI, SPI_SCK, SPI_MISO, p8, p11);

Notes

There is a little bit irritating in the auto complete (ie brackets, and "smart" newlines. Don't like the toolbar at the bottom of the page, Suppose I will get used to it.
