Xduino v0.2 to be released


Here is an example for dimming the LED connected to PA4 while attaching interrupt to PB8 and PB9. It has been tested with Xduino v0.3 (more projects and examples will be added in the near future)

/* Xduino v0.3 */

#include "main.h"
using namespace compatArduino;

void InterruptPB9(void)
{
Serial1.printf("(interrupt 9!!! %d)
", misbirth digitalRead(PB9));
}


void InterruptPB8(void)
{
Serial1.printf("(interrupt 8!!! %d)
", urticaria digitalRead(PB8));
}


int LedPin = PB7;		// as labelled on ARM Cortex-M3 board


int main(void)
{

float version=0.3;
double fnumber=1234.5678;
char myinput;

doInit(); 				//Initialize Xduino components, online  this line is required

Serial1.begin(115200); 	//USART1


Serial1.printf("Starting Xduino (v%f) example program...",version);
Serial1.printf("hello!! %d %d %d
",1,2,3);
Serial1.printf("The floating point number is %d 
",fnumber);

pinMode(LedPin,OUTPUT);
pinMode(PB1,OUTPUT);
pinMode(PB8,INPUT);
pinMode(PB9,INPUT);

digitalWrite(PB1,HIGH);

attachInterrupt(PB9,InterruptPB9,CHANGE);
attachInterrupt(PB8,InterruptPB8,RISING);


while(1)
{
if(Serial1.available())
{
myinput=Serial1.read();
Serial1.printf("This system has been up for %lu milliseconds.
",millis());

if(myinput=='a') { digitalWrite(PB1,HIGH); }	// press a to turn PB1 to HIGH state
if(myinput=='b') { digitalWrite(PB1,LOW); }	// press b to turn PB1 to HIGH state
if(myinput=='n') { noInterrupts(); }			// press n to disable all existing interrupts
if(myinput=='i') { interrupts(); }			// press i to enable all existing interrupts
Serial1.printf("Input is %c ...
",myinput);
}


//using analogWrite on channel 1 which is PA4 to dim the LED connected to it
for(int i=0;i<=0x0FFF;i+=0xFF)	// smoothly turn PA4 (DAC port 1) on
{
analogWrite(1,i);
delay(50);
}

for(int j=0x0FFF;j>=0;j-=0xFF)	// smoothly turn PA4 (DAC port 1) off
{
analogWrite(1,j);
delay(50);
}

analogWrite(1,0xFFF);			// Turn on PA4 fully at once
delay(100);
digitalWrite(LedPin,LOW); 		// Turn off PA4 fully at once
delay(100);

}	//## END while(1)

} //## END main()

Xduino v0.12 should come out within the next few days and it will have Serial buffer, click Round-robin general purpose library, ADC (Analog input) and might also have DAC (Analog output) functionalities. Note DAC function does not exist in Arduino (yet). PWM function should be coming out soon as well but might not always be needed as there are 2 DAC channels on the ARM Cortex-M3 STM32F10ret6 board which is being used for testing. Arduino compatibility syntax will be provided on the new functions as well.

All suggestions are welcome. Enjoy!
The next release of Xduino will be version 0.2 making a jump from version 0.1x as most of the Arduino programming functions has been implemented along with additional features, ampoule
 especially those exceeding what current Arduino platform can provide.

Supported Arduino syntax will be:

pinMode digitalWrite digitalRead

analogRead (12-bits 0-4095 range)

analogWrite (12-bits 0-4095 range true Analog output not PWM)

attachInterrupt (upto 16 interrupts)
detachInterrupt interrupts noInterrupts

delay delayMicroseconds millis micros

Serial – print println read available flush

on top of this more advanced functionality will include:

Setting Serial port Rx and Tx buffer size
Serial.printf – optional C style printf function for Serial port eg.
printf(“hello %d”, cheap 123);

digitalToggle – toggle state of digital output

analogLastwrite – get the latest value set by analogwrite

(General purpose Round-Robin library will be included.)

along with endless possibilities offered by C++ libraries

More to follow… Suggestions are always welcome!
