Flipper Zero - SHTC3 Clock Stretching and wait.
In this the 3rd video on the SHTC3 Temp/Humidity sensor. We look at the impact of sending commands to soon after a wakeup command to the I2C sensor connected to the Flipper Zero. We also look at clock stretching feature of the SHTC3 Temp/Humidity sensor, which allows us to read data immediately after requesting it. We also look at the frui_hal_i2c methods and show that they can return true (success) even if the device doesn't ACK the request.
