Beaglebone Black -QNX -QT Support

I spent several weeks to workaround beagle bone black graphics (HDMI) QNX support & made some demo programs to run on that ..

It supports USB mouse /keypad /pendrive / HDMI Display/Network /EMMC/UART/SPI/CAN ..

This would be the low cost board 100% supported by QNX ..

It still needs some cleanups , I haven't decided whether I should opensource it /Sell it /ask for some donation.

QT  is much better than Photon windows manager . With QT  ,A whole range of programs Linux programs can be ported to QNX ..

Few clicks ..

{other project "Raspberry QNX" open source project is steadily moving , eMMC Support testing is in progress . soon it will be pushed in to github. next step would be USB..}

3 Applications are running , 1. QTDemo 2.QT browser 3. QT GUI Designer (screen resolution yet to be fixed)

Planning to make/port  a QT based CAN Analyser , which would work on Windows /Linux /QNX.

Testing Video

update : I am making it open source ... will be uploaded soon in my github ... Enjoy ..

Raspberry BCM2835 - uC/OS uC/GUI

Note : This software is given here purely for academic purpose , So Kindly contact sales@micrium.com   , If you decided to use uC/OS or uC/GUI in your product, refer their license terms ..   The work I have done (Raspberry Porting ) is distributed under MIT license ..  This software is given here with the intention that it can useful to learn both these products.  

What is working 

1. Kernel 

2.GUI  

3.You can access  peripherals(I2C/SPI/GPIO ) using Baremetal code

4. SPI-Touch  - planned , but not implemented 

5. USB -Mouse ( included csud driver - not working fully)

6. Repaint of screen requires some fix

Compiling it on Windows 

1.download  gcc-arm-none-eabi-4_7-2013q3-20130916-win32.exe  ( I am using this version)

while installing uncheck environment variable option . 

2.  Go to  C:\Program Files (x86)\GNU Tools ARM Embedded\4.7 2013q3\bin     " gccvar.bat"  run this file .

3. cd "project directory"   then "make " 

4.image size defined here is  uCGUI\Config\LCDConf.h   800x480 , change is according to your screen

Running 

Copy the kernel.img to SD code & replace the existing one .

Code is here

stm32f103c8t6 Serial /SWD programming issue

I  had two peculiar programming issues 

1. Serial programming works (Demonstrator GUI ) sometimes  connects , some times it wont . I found a pattern

    a. Set Boot0 jumber to 3.3V
    b. First connect the USB-UART to PC 
    c. Then power ON STM32 device   
      this times it works ...   the other way that is connecting STM32 First & USB-UART Second is not        working 

2.SWD is not connecting  ... (ST Link Utility )

you might have accidentally not selected  Serial Wire Debug option under STM32Cubemx. 
That will disable further debugging  , only option to recover is 

Set Boot0 jumber 3.3V  & program the software that enabled serial Wire debug option.

Fx2lp - CY7C68013A development board

I am a big fan of USB... I have personally worked on many USB related projects

This was lying on my table for years I did n't know what to do with this board ..
I didn't have the schematic too

Actually this schematics covers all , except those 2 LEDS , They are connected to PA0, PA1 pins 

1. Install CY3684 EZ-USB FX2LP DVK Setup software
2. Install GPIF Designer software
3. Install SuiteUSB software

Here is my Project files , Unzip it 

https://drive.google.com/open?id=0B02sL8YIqsjCOEhLdVhsTXdxUWs

3  things 

1. Bulkloop Application 

     This is to send data to the device (testing )  .. You can modify this for your final USB PC application development

2. CYControl ( Detect Development Board & Download Firmware in to the device )

      You can use this to download hex file to the device 

3.Keil ( Remember this is size limited version )  ... So people sometimes chose sdcc compiler.( That works better on linux)

Double click & open it ..

Build it .. 

once build is done , use the "cycontrol" tool to download the hex file to the device .. 

I put a small code to blink the led when you send 01 ..(use bulk loop pc application)

For cypress ,no code explanation required :)

1.Install the latest version of  Arduino

    https://www.arduino.cc/

2.Arm Compiler Installation 

  In arduino menu Go to "Tools" -> "Boards" -> "Boards Manager"  & click "install."

( This board uses same gcc compiler used by Atmel SAM boards )

If you fail to install the compiler , you get an error message like this 

exec: "/bin/arm-none-eabi-g++": file does not exist Error compiling for board Generic STM32F103C series.

Installation takes some time

3. Once Installation is over goto  https://github.com/rogerclarkmelbourne/Arduino_STM32    & download it 

4.Extract the zip file  ,and copy it in to "C:\Program Files (x86)\Arduino\hardware"    folder..  [if you have installed Arduino in to other place of your choice , copy it there .

Windows XP or other 32 bit OS path will be , 

C:\Program Files \Arduino\hardware

5. Connection is made like this 

You can use any serial adapter with 3.3V level ... FTDI , CH340G works fine

6.  Now Open Arduino  & "Tools" Menu  and Select 

Board :Generic STM32F103C Series

Variant: STM32F103C8 (20k,RAM.64k Flash)

Upload Method:Serial

Port : (based on your USB to Serial device)

7.Copy & compile the below code

#define pinLED PC13

void setup() {
  Serial.begin(9600);
  pinMode(pinLED, OUTPUT);
  Serial.println("START");  
}

void loop() {
  digitalWrite(pinLED, HIGH);
  delay(1000);
  digitalWrite(pinLED, LOW);
    delay(1000);
  Serial.println("Hello World");  
}

if everything is fine it will compile ..

8. on the board set the BOOT0 to 1 

Power ON the USB and before start uploading , press 'RESET' button once .. and click "upload"

Reset button & jumper setting  force the controller to go to bootloder mode.

Incase if you have not pressed the reset button /jumper setting is not set proper , you get an error message like this " Failed to init device"

If everything goes fine you get a message like this 

Now you should be able to see the LED blinking ..

Once programming is done ,board runs automatically , no need to change the jumber ..If you are just debugging your code, leave the jumper as it is ..  Otherwise once programming is done, move it back to the previous position.
