I got that ET-JRAVR board but the schematic is wrong:

Does anyone have an updated schematic or the Protel file which can be edited and correcitons made.

The manual is also wrong:

This board comes from a Thai maker:

I got it from Futurlec and I can confirm that pins do not reflect the PDF schematic.

Thanks

email ETT. I have found them to be very supportive for their products I’ve ordered.

Yes, you are correct.

Very true, they were helpful. Thank you.

After digging I found great new manual and new CORRECT schematic of the JRAVR board. Here is the info:

[CP-jrAVR_Schematic.pdf

[CP-JRAVRUsersManual.pdf

Hope that will be useful to all!

Now that I got the schematic figured out my first code to run a little $5 LED board I got on eBay that uses SPI-line interface:

http://s193925491.onlinehome.us/Futurle … P001-5.jpg

#include <avr/io.h>
#include <util/delay.h>

const unsigned char Digital_TAB[] = {0xff,0xfc,0x60,0xda,0xf2,0x66,0xb6,0xbe,0xe0,0xfe,0xf6, 0x80,0x40,0x20,0x10,0x08,0x04,0x02,0x01};
int U, j, i;

void main(void)						//main function starts here
{
DDRB=0xFF;
while (1==1){						//cycle forever - main loop
	for(j = 0; j <19; j++)			//symbol from array 1-2-3-A-B-C-etc
	{
	U = Digital_TAB[j];
	PORTB |= (1<<PINB3);			 //turn OFF display, LOW pin 3
		for(i = 0;i < 8; i++)		 //character shift out ISP routine
		{
		PORTB = (PORTB & ~(1<<PINB1)) | ((U & 0x01)<<PINB1); 
		PORTB |= (1<<PINB2); 
		PORTB &= ~(1<<PINB2); 
		U = U>>1;
		}
	PORTB &= ~(1<<PINB3);			 //turn ON display, HIGH pin 3
	_delay_ms(100);
	}
}
}

Woo hoo, it works. That Atmel board is actually very useful for these kinds of tests.

But bottom line is - you are correct, ETT did help

Thanks
