Hi ! sorry about my English , it isn’t my mother tongue
“bootloader will run for five seconds waiting for a program to be uploaded through the port”
but when I had download the program , and begin to use this borad , this “five seconds” waiting make me a little worry, is there someway to set this waiting time ? or is there a way to make the board run my program at once?
for example, could we do some change to bootloader, when press the reset button , the LED between pin 13 and ground you will see it blinking(set the blinking time longer, about 1s),
when it blinking ,
if you press the reset button again, then enter the “program mode” , bootloader will run for five seconds waiting for a program to be uploaded through the port.
if you didn’t do the secondly press,when blinking time over,the board will run my program at once.
Is it possbile?
