ok thank you very much... i have a last question to ask!? Can i open a topic in this forum to explain how built a TPA 81 sensor and how can you programme it with NXC. Because on the web there aren't examples in NXC

yes this is great thank you very much but the sensitivity of tpa81 is low.... i put a candle in front of the sensor but only one value of the pixel increase...for example if i put a candle in front of the tpa81 the values that i see on the lcd lego display are: 25,21,31,65,103,21,23,26
why this?

Yes but the TPA81 has got 8 pixel to read the temperature. With this programme i read only one value of temperature but can i read the temperature of all eight pixel? How i can do it?

Yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeahhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i read the temperature on the lcd lego display from the TPA81 using NXC language :D i use this code: // READ TPA81 #define TPA81_PORT IN_1 #define TPA81_ADDR 0xD0 void MyI2CRead(byte port, byte addr, byte reg,...

yes this is the code that i try but it's wrong! //#define S1 1 //#define I2C_ADDR_DEFAULT 0xD0 //#define I2C_REG_CMD 0x11 //char ReadI2CRegister ( byte port, // byte i2caddr, // byte reg, // byte & out // ) [inline] byte out; char result; byte CMD_Read[] = {0xD1, 0x11}; task main() { SetSensorTy...

Hi i'm Davide and i bought the TPA81 three weeks ago. I would to use the sensor with my Lego Mindstorm NXT 2.0 and i would to read the temperature from the sensor. The hardware part is finished: I use four pins of the TPA 81: I use Vcc +5V and i connect this pin to the green wire (+4,3V supply) of t...
