Invalid conversion from 'char' to 'char'

How can I fix the code?

// simple parse demo
char receivedChars[] = "This is a test, 1234, 45.3" ;
char byteRead;
char messageFromPC[32] = {0};
int integerFromPC = 0;
float floatFromPC = 0.0;

char recvChar;
char endMarker = '>';
boolean newData = false;

void setup() {
Serial.begin(9600);
Serial.println("");

parseData();
showParsedData();
}

void loop() {

if (Serial.available()) {
/* read the most recent byte */
byteRead = Serial.read();
}
}

void parseData() {

// split the data into its parts

char * strtokIndx; // this is used by strtok() as an index

strtokIndx = strtok(byteRead,","); // get the first part - the string
strcpy(messageFromPC, strtokIndx); // copy it to messageFromPC

strtokIndx = strtok(NULL, ","); // this continues where the previous call left off
integerFromPC = atoi(strtokIndx); // convert this part to an integer

strtokIndx = strtok(NULL, ",");
floatFromPC = atof(strtokIndx); // convert this part to a float

}

void showParsedData() {
Serial.print("Message ");
Serial.println(messageFromPC);
Serial.print("Integer ");
Serial.println(integerFromPC);
Serial.print("Float ");
Serial.println(floatFromPC);
}

strtok() cannot work on a single byte - think about it. It needs a c char array, an array of chars with the last character being '\0'. You need to create such an array.

Do you mean this char?

char byteRead[20];

The program structure is such that it can't do anything useful.

setup() calls parseData before you have any characters to parse.

All loop() does is collect one character from the serial input, repeatedly.

You have to collect an entire string (hopefully, a meaningful line of input) from Serial.read, then process it.
