Hi,
I am new to the arduino forum so firstly HELLO.
I have been experimenting with the Arduino NT Board an a TLC5940 NT chip.I am not a realy experienced user of arduino syntax and I have come up with a problem with the Serial.read() function. I have done a lot of search but couldn't find any relavant info. Maby someone can please hepl me.
I used the TLC Libary --> example "Serial". Everything works when i send DEC Numbers But then I send an ASCII Code from VVVV and tryed to read this as an integers (not char) at the arduino serial port. And now the the Arduino bord do`s nohing any more
these are the part`s i change:
#define SET_COMMAND '115' // befor `s`
#define COMMAND_ARG_DELIMITER '44' // befor `,`
and
void loop()
{
if (Serial.available()) {
if (serialBufferSize < MAX_LINE_LENGTH) {
int c = Serial.read(); // befor "char"
Serial.print(c);
if (c == ' ') {
Serial.println();
doSet();
serialBufferSize = 0;
} else {
serialBuffer[serialBufferSize++] = c;
}
} else {
serialBufferSize = 0;
}
}
}
--> I hope someone knows!!!
Here is the code.
#include <TLC5940LED.h>
#define NUM_TLCS 1
#define MAX_LINE_LENGTH 200
#define SET_COMMAND '99'
#define COMMAND_ARG_DELIMITER '32'

uint8_t serialBufferSize = 0;
bool isNumber(char c)
{
return c >= '0' && c <= '9';
}
uint16_t parseDec(char *cpStart, char *cpEnd)
{
uint16_t result = 0;
uint16_t ten = 1;
for (char *cp = cpEnd - 1; cp >= cpStart; cp--) {
char c = *cp;
if (isNumber(c)) {
result += ((*cp) - '0') * ten;
ten *= 10;
}
}
return result;
}
void doSet()
{
char *cp = serialBuffer;
if (*cp == SET_COMMAND)
{
cp++;
char *cpEnd = cp;
while (cpEnd < serialBuffer + serialBufferSize && *cpEnd != COMMAND_ARG_DELIMITER)
{
cpEnd++;
