The README.md includes a dependency which is not available on pip.
It seems that the project was changed to python-periphery.

I am sending a PR with the modification, in order to keep the documentation up-to-date.

PS: Really cool project, congrats!

Hello,

Thank you very much for your work. I would like to know how to get the temperature per pixel or the max temperature of the image.

def get_eeprom(self, eeprom_address=0x50):
# Two separate I2C transfers in case the buffer size is small
**q1 = [I2C.Message([0x00, 0x00]), I2C.Message([0x00]4000, read=True)]
q2 = [I2C.Message([0x0f, 0xa0]), I2C.Message([0x00]4000, read=True)]
self.i2c.transfer(eeprom_address, q1)
self.i2c.transfer(eeprom_address, q2)
return np.array(q1[1].data + q2[1].data)

The function above was taken from htpa.py code. what I understand is you are reading 4000 number of bytes from 4 location from the EEPROM, (0x00,0x00,0x0f,0x0a). Please explain this two line I bold up in the function on what is happening and is my understanding correct?

Actually this is more for explaination and details rather than an issue.

Thank You.

in the htpa.py script around line 171, the loop is never broken. The value of query[1].data[0] is 1 for the first block and so the loop keeps looping.

I am using the Heimann 32x32 sensor and it works with their software ok. Is there something I am doing wrong?

1. Does the sensor has variable gain? Could the temperature range be changed?
2. Need to start sensor early enough to get correct temperature values?
3. Sometimes(randomly, say twice or thrice in 100 frames) it reads 0 for pixel and offset values.

Does this work with the Dell XPS 13 IR emitter?

i see the sensor conencted

 0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

when i start the application i get

root@Wello9944:~/wello# python2 ./dualcam.py

Capturing image

which tells me it finds the sensors.. but all iget on the left screen is a black screen, i cannot calibrate or see any visual. suggestions? htpa.pyc gets output in the folder as well
