Hello ,i have a problem with poll Serial , when i receive information on serial communication the word or the sentence is cut and the word is not clear , an example it’s , i sent test and i received te or tes and sometimes all letter.I need help !
Thx !
some problem i try speed at 19200 or 115200 and some problem master
void setup()
{
Serial.begin(19200);
}void loop()
{
Serial.println(“test”);
delay(100);
}and slave
#include
#include
#include#define W 128
#define H 98TVout tv;
pollserial pserial;void setup() {
tv.begin(PAL, W, H);
tv.set_hbi_hook(pserial.begin(19200));
initOverlay();
tv.select_font(font4x6);
tv.fill(0);
}// Initialize ATMega registers for video overlay capability.
// Must be called after tv.begin().
void initOverlay() {
TCCR1A = 0;
// Enable timer1. ICES0 is set to 0 for falling edge detection on input capture pin.
TCCR1B = _BV(CS10);// Enable input capture interrupt
TIMSK1 |= _BV(ICIE1);// Enable external interrupt INT0 on pin 2 with falling edge.
EIMSK = _BV(INT0);
EICRA = _BV(ISC11);
}// Required to reset the scan line when the vertical sync occurs
ISR(INT0_vect) {
display.scanLine = 0;
}void loop()
{
if(pserial.available())
{
char c = pserial.read();
pserial.print(c);
}
}I would not initialize the serial communication at the beginning of every horizontal scan line. Instead of this:
tv.set_hbi_hook(pserial.begin(19200));try this
pserial.begin(19200);i don’t know what to tell you. I’ve used it successfully. Since I didn’t write these libraries, I can’t support them very well, ya know? I support my hardware. Try a higher speed yet.
