This repository provides examples that demonstrates how to develop PSoC 6 MCU based analog designs. These examples help you to use peripherals like ADC, DAC, Comparators etc. If you are new to developing projects with PSoC 6 MCU, we recommend you to refer the PSoC 6 Getting Started GitHub page which can help you familiarize with device features and guides you to create a simple PSoC 6 design with PSoC Creator IDE. For other block specific designs please refer to the following GitHub repositories:
You can use these block level examples to guide you through the development of a system-level design using PSoC 6 MCU. All the code examples in this repository comes with well documented design guidelines to help you understand the design and how to develop it. The code examples and their associated documentation are in the Code Example folder in the repository.
To use the code examples in this repository, please download and install PSoC Creator
Note Please refer to the code example documentation for selecting the appropriate kit for testing the project
This code example demonstrates how to set the Component options for the LPComp internal reference voltage and how to set the external input from a GPIO using the LPComp driver. The code example uses one GPIO input to compare the input voltage and internal reference voltage to wake the PSoC 6 MCU from Hibernate mode. The LED indicates the current power mode.
This example demonstrates the voltage comparison functionality using the LPComp Component in PSoC 6 MCU.
This example generates a sawtooth wave by incrementing through all 4096 unique codes of the Voltage DAC (12-bit) Component using an interrupt service routine. Both the PSoC Creator™ Voltage DAC (12-bit) Component and underlying lowlevel Peripheral Driver Library (PDL) Continuous Time DAC (CTDAC) function calls are shown.
This example generates a sine wave using the Voltage DAC (12-bit) and DMA Components. The DMA Component transfers data from a lookup table to the DAC value register without any CPU intervention. Other than function calls to initialize and enable the hardware, there are no other software operations. Both the PSoC Creator™ Voltage DAC (12-bit) Component and underlying low-level Continuous Time DAC (CTDAC) PDL function calls are shown.
This example demonstrates how to maintain the VDAC output voltage using the sample and hold capacitor while in Deep Sleep mode. Both Component and low-level Peripheral Driver Library (PDL) function calls are demonstrated. When the voltage across the capacitor drifts below the internal 1.20-V bandgap voltage, the comparator wakes the device to re-sample the VDAC output. When the device wakes up, the red LED on the kit is toggled for a visual cue.
This example demonstrates a simple OpAmp gain stage and a Comparator using VDAC as a programmable reference. Both Component and low-level PDL function calls are shown to configure and use the OpAmp, Comparator, Comparator interrupt, VDAC, and internal analog routing.
This example demonstrates a Scan_ADC with two conversion configurations implemented using direct PDL functions calls. The example selects between a fast free-running two-channel differential system and a firmware-triggered scan with averaging of the internal die temperature (DieTemp) sensor. The DieTemp sensor is scanned once per second using a watchdog timer. Results of all channel readings are transmitted over UART.
PSoC 6 bridges the gap between expensive, power hungry application processors and low‑performance microcontrollers (MCUs). The ultra‑low‑power PSoC 6 MCU architecture offers the processing performance needed by IoT devices, eliminating the tradeoffs between power and performance. The PSoC 6 MCU contains a dual‑core architecture, with both cores on a single chip. It has an Arm® Cortex®‑M4 for high‑performance tasks, and an Arm® Cortex®‑M0+ for low-power tasks, and with security built-in, your IoT system is protected.
