A In External Clock Input. The 4-wire SPI connection between the accelerometer and the microcontroller is also shown. Also, they’re convenient components for this 12V system because they operate from a 12V supply.

Refer to Table 5 for the H1 terminal block connections. Building and Downloading the Program for Debugging 1. This pin is the excitation driver for an external crystal or resonator. This document does not imply or express copyright licenses granted hereunder to design or fabricate any integrated circuits. Evaluation board datasheet Device datasheet.

August 31, by Nick Davis This project uses a C microcontroller development kit, an accelerometer evaluation board, and Simplicity Studio IDE—all from Silicon Labs—to rather quickly datssheet easily build a motion-detecting alarm system. The alarm and the lights will stay energized until the microcontroller is reset. G Optional Analog Ground. Silicon Laboratories cannot retest any wafers that have been sawed, diced, backgrind or are on tape.

It’s time to assemble Characterization data, available modules and peripherals, memory sizes and memory addresses refer to each specific device, and “Typical” parameters provided c8501f930 and do vary in different applications. The capacitors are connected to P0. Register 0x32 sets the acceleration threshold set to mg for when the Int1 signal is driven; the mg threshold setting is what makes the motion detector so sensitive to slight accelerations.


In dwtasheet, this issue had me stumped before I resorted to utilizing an SPI bus analyzer. The CF Development Kit is intended as a development platform for the microcontrollers in the.

Build Your Own Motion Detection System Using an Accelerometer

Serial Interface Header J12 Description 7. The operation of these switches require appropriate firmware running on the CF MCU that can sense the state of the switch. Ordering Information Table 1. This pin is the external oscillator return for a crystal or resonator. Target Board The CF Development Kit includes a target board with a CF device pre-installed for evaluation and preliminary software development.

Copy your embed code and put on your site: The audio piezo alarm chosen for this project is a slow warble alarm with a resonant frequency range of to Hz. This pin is the external clock input in external CMOS clock mode. Silicon Laboratories products are generally not intended for military applications.

What can reduce active supply current? J2[8] and H1[2] connectors. The CF Development Kit should become visible as an option—click on this option see Figure 8 below. In addition, power supply and ground pins are included.

Although datashret clearly called out in the accelerometer datasheet, they are mentioned. Figure 9 on page 14 shows the factory default shorting block positions This pin can supply power to external devices when operating in single-cell battery mode.

This alarm has its own internally driven circuitry and operates from 5V to 15V, which is perfect for this project because we have 12V readily available. Windows will automatically finish the driver installation.


Figure 9 shows the positions of the factory default shorting blocks. You May Also Like: On the Project Configuration screen, leave everything as c8501f930 see Figure 9 below then click Finish.

In-system Flash memory programming integrated into the driver allows for rapid updating of target code. Prev Next CF D. This kit comes with the CF microcontroller installed—see Figure 1 below.

Silicon Laboratories, Inc. C8051F930

External VREF decoupling capacitors are recommended. See Figure 9 below. After receiving the interrupt signal, the microcontroller then turns on two external FETs thereby energizing both the audio alarm and the two LED flood lights. In single-cell battery mode, this pin must be connected to VBAT through a 0. The Crossbar cannot route signals to this pin and it cannot be configured as an analog input. Once you have completed the configuration changes to the microcontroller, you’ll have to add all the code to correctly configure the accelerometer.

CFGM 8-bit Microcontroller – Silicon Labs

To create a new profile: V8051f930 can be seen, I have configured register 0x20 in such a way that only the X and Y axes are enabled. It is stopped high when CS is high no transmission. Can be used as a bias or for generating a custom reference voltage ports UART operation; 20 MHz low power oscillator requires very little bias current External oscillator: Below are some suggestions for reducing the active supply current: Keil Assembler and Linker The Keil demonstration toolset assembler and linker place no restrictions on code size.
