Overview ¶
Ads1115 communicates with the ADS1115 analog to digital converter using I2C protocol. It uses the single-shot mode of operation to periodically start an A/D conversion to read a voltage between the AIN0 and ANI1 pins.
This example presents two possible ways to communicate with an I2C device. The first one uses the low-level interface (lowLevelWay function), the second one uset the connection interface (connWay function). The low-level interface may be more efficient and simpler in some specific cases. The connection interface is more portable. Both can be used simultaneously as in this example. If used concurently by multiple gorutines, the low-level interface require using the Master.Mutex to ensure exclusive access to the Master driver (the connection interface does it by default).
This exapmle also presents how to use the I2C High-Sped mode. If you encounter errors try to disable it. In case of the connection interface it's easy: simply remove the i2cbus.HS flag from the adderess. In case of the low-level interface you have to some remove/change Start* commands so it requires more knowledge. If you are unsure how to do it simply comment out the lowLevelWay function call.
