This code example demonstrates the UART transmit and receive operation in PSoC 4. The application uses a serial terminal to read data and to echo back the received data. The UART resource is configured to do both transmit and receive operations.
CapSense Flanking Sensor Suppression in PSoC 4. This code example implements Flanking Sensor Suppression (FSS) in PSoC™ 4 devices. FSS eliminates false touches by distinguishing between signals from closely spaced buttons.
This example demonstrates the operation of I2C resource for PSoC 4 in Master mode with an EzI2C slave. The I2C master is configured to send command packets to control a user LED on the slave. Both the slave and master are on the same device.
This code example demonstrates the use of a GPIO configured as an input pin to generate interrupts on PSoC® 4. The GPIO signal interrupts the CPU and executes a user-defined Interrupt Service Routine (ISR).
This code example demonstrates how to tune self-capacitance (CSD)-based buttons and slider widgets with SmartSense in PSoC™ 4 devices using the CAPSENSE™ tuner.
This code example demonstrates the use of the multi-frequency scan (MFS) for PSoC™ 4 CAPSENSE™ applications to prevent false touch detection in the presence of external noise. This code example demonstrates this feature for both CSD (self-capacitance) and CSX (mutual-capacitance) designs.
This code example demonstrates how to implement pipeline scanning in CAPSENSE™ to improve performance. When a particular widget is being processed, the next widget in line can be scanned in parallel, and the device remains in Deep Sleep mode until the scan is complete.
