MCU and boards testing

We are currently testing out some additional MCUs some comes with Ethernet so the inclusion of TCPIP stack could be included in the future scope. We also have received some request from Apple/Mac OSX users and as we currently don’t have access to any Apple/Mac OSX system and without any funding we cannot proceed on this. However, information pills if we can get some substantial sponsorship/donation we will proceed on this as well as intensively continue our development.

Xduino 0.3 released

(So far Xduino v0.3 has only been tested on board with STM32F10ret6 mcu.)

There are a few things to keep in mind when using Xduino v0.3

Major Features:
All Arduino syntax are compatible with Xduino v0.3 (as per Arduino references and Arduino extended references page except for analogReference() command.

Serial ports
There are total of 5 serial ports so Serial1-5 commands can be used.
There is also a special serial port output command ‘printf’ this function can be used like the general C/C++ printf function on the Serial command like

Serial1.printf(“Xduino v%f
“, unhealthy 0.3);

Math library (math.h)
Mathematical functions are included. For full information please check this math.h page.

Standard library (stdlib.h)
Standard library functions are available. For full information please check this stdlib.h page.

Other C or C++ libraries
Other C and C++ libraries can also be included, psychiatrist extending the limitation of functionality.

Analog ports
All Analog input and Analog output channels have 12-bits data. This means that when reading analog channel by using analogRead() command the returned value is between 0 and 4095 and when writing to analog output channel one can write value 0 and 4095.

Analog input channels (ADC)
There are total of 15 analog input channels with the following channel name corresponding to the Pin on the board:

Analog input channel (ADC) Pin on board
0 PA0
1 PA1
2 PA2
3 PA3
4 PA4
5 PA5
6 PA6
7 PA7
8 PB0
9 PB1
10 PC0
11 PC1
12 PC2
13 PC3
14 PC4
15 PC5

Analog output channels (DAC)
There are 2 DAC channels and each correspond to a port as follow:

Analog output channel (DAC) Pin on board
1 PA4
2 PA5

AnaloglastWrite() function can be used to retrieve the last value written to the analog output (DAC) channel. For example, to get the last value written to analog output channel 2:

int lastvalue;
lastvalue=analogLastwrite(2);

Interrupts
There are total 16 interrupt channels for digital input pins, the interrupt. Each pin ‘number’ can only be assigned an interrupt. This means that interrupt cannot be assigned to PA5 and PB5 at the same time as the pin ‘number’ is the same.
(note: the interrupt handling function must appear before main() directive of the program if not declaring a function prototype)

pause(ms) and pauseMicroseconds(us)
(delay possible within interrupt routine)
Generally the use of delay functions are not possible within the interrupt handling routine and this is where pause(ms) and pauseMicroseconds(us) comes in. Just specify the number of milliseconds/microseconds to pause the program and pause will handle it even within the interrupt. Note that pause only “approximate” the time to delay.
Example: to pause for approximately 10 milliseconds

pause(10);

Important file setup
To get interrupt functions and timing function working properly the following lines must be added to stm32f10x_it.c appropriately:

void SysTickHandler(void) { SysTick_IRQ_Function(); }

void USART1_IRQHandler(void) { USART1_IRQ_Function(); }
void USART2_IRQHandler(void) { USART2_IRQ_Function(); }
void USART3_IRQHandler(void) { USART3_IRQ_Function(); }
void UART4_IRQHandler(void) { UART4_IRQ_Function(); }
void UART5_IRQHandler(void) { UART5_IRQ_Function(); }

void EXTI0_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI1_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI2_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI3_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI4_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI9_5_IRQHandler(void) { EXTI_ALL_IRQ_Function(); }
void EXTI15_10_IRQHandler(void){ EXTI_ALL_IRQ_Function(); }

Additional minor features
digitalToggle() command can be used to toggle the digital state of the pin from high to low or from low to high. For example to toggle the state of pin PC2

digitalToggle(PC2);

Finally Xduino version 0.3 has been released. This version has all Arduino platform functions except for analogReference() function.

On top of the the above, viagra buy
Xduino have taken a step further by extending the functionalities above and beyond current scope. For more information please check the Documentation section.

This version also includes Keil RV-MDK project file example.

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.

ARM programming made simple with Xduino (v0.11)

With the current release of Xduino v0.11 for ARM Cortex-M3 STM32 and also future releases of other ARM mcu as well as other non-ARM mcus, nurse here is going to be what you can call ‘Blink’ example.

Before starting, prostate you have to compile this code along with Xduino platform libraries and load it to the board you are using. Once loaded then you can disconnect the board from the computer then connect one wire of an LED to PB7 (you can change this to other Pin on your board, thumb make sure to also change the code) and the other to ground appropriately. Hit reset on your board and the LED should blink.

/* Xduino library initialization */
#include “main.h”

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

int main(void)
{

doInit(); //Initialize
while(1) //loop this block
{
        digitalWrite(LedPin,HIGH);
        delay(200);
        digitalWrite(LedPin,LOW);
        delay(200);
}

}
