Product review: iCP12 usbStick and SmartDAQ
In this blog post, I am reviewing iCircuit Technologies’ iCP12 usbStick development board and their freely downloadable SmartDAQ PC software. These two can be bundled together to construct a very basic 6-channel (analog) PC data logger.
The iCP12 usbStick is a PIC18F2550 based USB development board that comes preloaded with Microchip’s USB HID bootloader that allows users to upload an application firmware directly through a PC’s USB port without any external programmer. It provides access to its I/O pins through 0.1″ pitch headers. A slide switch is also provided on board to select the operation of the board in Bootloader or Normal mode. The iCP12 usbStick board is shipped with a preloaded data acquisition firmware (HEX file is also downloadable) that emulates as a virtual COM port to PC. Thereafter, the communication between the PC and usbStick is serial. The firmware also supports basic I/O control and data logging feature. They provide a PC application named SmartDAQ that is specially developed to communicate with the usbStick (data acquisition firmware must be loaded) and control its I/O pins, PWM outputs, and record ADC inputs.
SmartDAQ has a very friendly GUI with real-time waveform displays for 6 analog input channels. The time and voltage axes scales are adjustable. SmartDAQ can log the ADC data in both text and graphic form concurrently. One can utilize this feature to construct a low-cost data acquisition system for monitoring multiple analog sensor outputs such as temperature, accelerometer, gyroscope, magnetic field sensor, etc.
Testing with Easy Pulse
I tested the analog signal logging feature of SmartDAQ with my Easy Pulse sensor, and it worked out pretty good. I powered the sensor board through USB 5V output from usbStick and connected the analog PPG output from my Easy Pulse sensor to A0 input of the iCP12 usbStick board. When you connect the usbStick to PC’s USB port, it appears as a virtual COM port. Make sure the mode select switch on board is placed to position B (normal mode). You should select the appropriate COM port in the SmartDAQ software while connecting to the usbStick. On the GUI, PORT A0 is selected as Input, and the Analog, and Record boxes are checked. When Start and Run buttons are clicked on, the data logging is enabled and the Graph window shows the real-time waveform of the signal received at the A0 input of PIC18F2550.
The log files contain all analog input voltages into ASCII format with data and time stamps obtained from the PC, which are useful for future analysis of the recorded samples. The sampling interval is adjustable from 1 millisecond to 60 minutes. Besides analog sampling and recording, you can also control individual I/O pin logic state and set frequency and duty cycles of two PWM output pins (RC2 and RC1) of PIC18F2550 through the SmartDAQ interface.
At the price of $12.80, the iCP12 usbStick board is a real bargain, specially for hobbyists who are looking for a low cost PC data logger for capturing multiple analog sensor data. As a standalone PIC development board, the usbStick has a limitation that it lacks onboard power supply regulator.
How do you load the firmware to the device?
I have the device and the hex file and smartDAQ software.
What next to get it going please?

Dear All, this iCP12 usbStick is supporting following operating systems (32bit/64bit): Windows XP ,Windows Vista, Windows 7, Windows 8, Windows 10, Linux, Mac OS X and Raspberry Pi. Only the SmartDAQ software is available in Windows OS. More information (driver, software..) please visit our website. Please feel free to contact us (email@example.com) if you have any question on it. We will try our best to help you. Regards, PICcircuit.com
I just received my iCP12-V1.2, but there wasn’t any instructional material or trouble shooting literature that came with the mailing, just the circuit board itself. I plugged the unit into a Windows 10 operating system (OS) and Windows 7, neither OS recognized the circuit board, so what’s the big idea? One would think your company would provide more support for products sold. I may have to return the item to Amazon.com for a refund for this reason. Incidentally, what operating system of Windows is this chip compatible with?
Contact the seller or manufacturer for any issue. We are not affiliated to any of them.
I agree. I am excited to use this but I cannot get my computer to connect/recognize to it. No instructions or troubleshooting tips 🙁
That’s funny – mine doesn’t work at all. SmartDAQ and the Bootloader interface can’t even find it.
I have built an oscilloscope based on the 18F4550, which is very similar to the 18F2550. Do you know of a way to get SmartDAQ to work with my 18F4550?
