Hello everyone, I'm currently working on a project using a UDOO NEO Board and the FreeRTOS kernel. A previous worker interfaced the UDOO temperature sensor with a screen to display real time temperature. I have to do the same, but with brightness using TSL2561. I think I can already send and receive informations from and to the sensor ("think" because it seems to be wrong value, the ID returned is 6 or 8 when it's supposed to be 0, 1 ,4 or 5). Moreover, it seems that the measure are taken in "one shot", with the sensor working only once when it's powered up. If anyone have any advices, I can provide the code if needed. Thank all a lot, Nicolas KIEGER.
