wait i see, i forgot tinywire.begin, let me revise and retry.
SUCCESS!
thank you C.B.
i just got to put it all together now. revised read/reset/send sketch that works. i use putty, can save it to putty log and import to excel, as long as i know when readings started, i can add the times to excel afterwards, eliminating an rtc for this project. (which i may add anyway later on) thanks again.
#include <TinyWireM.h>
#define IO_ADDR 0x50
byte data;
unsigned int pointer=0;
void setup(){
TinyWireM.begin();
Serial.begin(9600);
Serial.println("test");
for (int i=0;i<20;i++){
TinyWireM.beginTransmission(IO_ADDR);
TinyWireM.send(pointer>>8);
TinyWireM.send(pointer & 0xFF);
TinyWireM.endTransmission();
TinyWireM.requestFrom(IO_ADDR,1);
data=TinyWireM.receive();
pointer++;
Serial.println(data,DEC);
}
}
void loop(){
}
