RE:Fifth Preview of TinyCLR OS Core Features and Porting by Justin on Jul 7, 2017 at 3:53pm

@Honken - ESP Wifi on top STM etc underneath, i cant remember size as i am away from the PC doing said domestic duties...

RE:Fifth Preview of TinyCLR OS Core Features and Porting by Justin on Jul 7, 2017 at 3:39pm

@Gus - Alas since its already Saturday here i have a day of domestic duties so it will be another 12 hrs or so until i get to play with compilers Sad

I haven't had time to do a flashy video so you will have to make do with this for now Cheesy

TinyCLR OS running on a Carbon 2.0 which has a STM32F411 uC

LED strip is using SPI
Dongbu's are using UART

Awesome work from the GHI Minions...

Happy days Clapping

Pick 2 looks like an Embedded Cray-1 Grin

RE:TinyCLR extension with vs2017 pro by Justin on Jul 3, 2017 at 11:30pm

Works fine with Pro.

LQFP64

Little dot is pin 1

Reffer to STM32F401 datasheet for footprint details etc.

@hwalker_MIWV - ping me an email if you want.

I wish I was working in New Zealand I applied for a work VISA but couldn't line a job up even though the government is looking for mechanical engineers. Although, microwave engineering in Florida turned out to be pretty damn badass.

New Zealand is a mint place to live in...

Next time you apply for a Visa mention you are more than happy to turn feral like the locals and run around the countryside wearing a grass skirt in bear feet drink a few tins of Lion Red.... Grin

RE:G30 Design Project by Justin on Jun 22, 2017 at 4:35pm

@hwalker_MIWV - there was no mention of price so i went for the gold plated version Smiley

A spiders doodle is only a few microns thick and as we all know there are 2.5 flim flams per micron so ~ 0x07 FF's or so..

L6470 will give you 128 micro steps so 0.0140625 deg resolution - dam the mechanical backlash Cheesy

L6470 are $7.72 in singles and in 1000's are $4.38 from Mouser

Here is said L6470 using G80 type uC and N18 type display

RE:G30 Design Project by Justin on Jun 22, 2017 at 2:26pm

@hwalker_MIWV - Yes i am using a custom Display class - but not as custom as you probably think.

The stepper IC i mentioned has 128 micro steps so with a 1.8 deg stepper can step about 2 thicknesses of a spiders doodle.

Just ask @John Smith - he likes steppers....

RE:G30 Design Project by Justin on Jun 21, 2017 at 9:17pm

@hwalker_MIWV - Good luck with your first real world project - exciting times and scary in equal measure Smiley

I have done a similar project to what you have spec'd with excellent results.

Display is basically an N18 https://www.ghielectronics.com/catalog/product/425
Stepper controller is the same IC as https://www.ghielectronics.com/catalog/product/418

So you can happily use a G30 with the above are similar with excellent results.

Here is some sample code that writes a random number in blue via SPI - your code will have slightly different Pin assignments rather than Socket.Pin

using System;
using System.Threading;
using Biospherical.Hardware.ProPower;
using ILI9163;
using Microsoft.SPOT;

namespace ProPowerN18Test
{
    public class Program
    {
        private static Display _display;
        private static readonly Bitmap Bitmap = new Bitmap(118, 20);
        private static readonly Font Font = Resources.GetFont(Resources.FontResources.Arial16);
        private static Random _rnd;
        public static void Main()
        {
            _rnd = new Random();
            _display = new Display(Socket1.Three, Socket1.Five, Socket1.Four, Socket1.Six, Socket1.SpiModule);
            new Thread(Spam).Start();
            Thread.Sleep(Timeout.Infinite);
        }

        static void DrawString(string text, uint x, uint y, Color colour = Color.White)
        {
            Bitmap.Clear();
            Bitmap.DrawText(text, Font, (Microsoft.SPOT.Presentation.Media.Color)colour, 0, 0);
            _display.Draw(Bitmap, x, y);
        }

       
        static void Spam()
        {
            for (;;)
            {
                DrawString(_rnd.Next(99999999).ToString(), 0, 100, ColorUtility.ColorFromRGB(0, 0, 255));
            }
        }
    }
}

@Dave is fending off dementia but the rest of you are spiraling down hill.... : Smiley

U7 is indeed an ADXL350 accelerometer
U3 is a MS5803-14BA 0-14 Digital pressure sensor

Still lots of guessing to go to ward off synaptic misfires.....

Since your all bored.... by Justin on Jun 19, 2017 at 5:00pm

...waiting for Gary to finish 3rd lunch to finishing migrating your favorite digital crack i thought why not lets have a game of guess the packages, bets Sudoku to keep the grey matter from disintegrating Grin

So...chocks away and see how many you can pick...

RE:Cause i know @Mr. John Smith likes dSpins by Justin on May 25, 2017 at 4:27pm

@Mr. John Smith - there are other things brewing Wink

RE:Cause i know @Mr. John Smith likes dSpins by Justin on May 25, 2017 at 4:26pm

@Gene

Board is using a STM32F427VIT6 (Similar to G80) running NETMF 4.4
RS485 for coms
dSpin for stepper
Gadgeteer socket for display
Other header pins for SPI secret squirrel sensor

There is dSpin code in codeshare that you can play with now Grin

How about an update on THE big project?

Which one? Whistling

RE:Cause i know @Mr. John Smith likes dSpins by Justin on May 23, 2017 at 3:47pm

@Mr. John Smith - And for Completeness² said Led's can be enabled/disabled via U6 so 470nm lumens dont effect other instruments Smiley
