(SCL) to the Slave device. The data (SDA) signal is bidirectional. Both SCL and SDA are pulled up to VDDIO via a resistor. Figure 11 shows the setting procedure and operation example for I2C Slave mode. START (1) Configure...
The common practice here is to call this function on initial boot of the MCU or when the device wakes up from sleep mode with all of the register configurations lost. Table 2-15. Parameters in config Pointer to configuration structure returnCode Table 2-16. Return Values An instance of tHC...

• The Pi-network is only intended for flexibility and for testing. It is not populated as the integrated balun provides the necessary matching. • The 32kHz crystal allows lower power consumption BLE Sleep Mode. • The inductor allows lower power consum...
This resistor (R2) ensures that the LEDs don't draw so much current they blow themselves out.This pair of glasses has a 2x2 array; 2 parallel arrays of 2 LEDs in series. The LEDs probably have a forward voltage of 1.9v and a typical 20mA current requirement. If we changed to, for ...
If you're using the LED recommended below then a 1000 ohm resister to the 2N2222 transistor and a 10 ohm resistor to the LED itself are appropriate values, otherwise please use an LED resistance calculator. In total the parts come in around $10 so building a controller for each IR ...
The bq27410 enters SLEEP if Average Current ≤ Sleep Current Normal Setting: This bit defaults to a 1, which is used in most applications. Only a few reasons require this bit to be set to 0. • RMFCC [3]: If set, on valid charge termination, Remaining Capacity is updated with the...
What this means is that the chip can drive its output low, but it cannot drive it high. For the line to be able to go high you must provide pull-up resistors to the 5v supply. There should be a resistor from the SCL line to the 5v line and another from the SDA line to the 5v...
The input impedance at A0 is 330Kohm (probably true for all such boards), so if you want to increase the max voltage further, you can add a resistor in series with A0 R = Vmax * 100-330 K. As I said previously if you want to decrease the Vmax with a little soldering* skill you...
