0-500MHz PIC16F876 RF Power Meter
Posted on Tuesday, April 20, 2010   •   Category: Test and Measurement


RF Measurement has been an expensive work so far the cost of measuring RF Power Meter instruments are concerned. RF Power Meter is based on PIC16F876 microcontroller, AD8307 and 2x20 LCD display. Full documentation is included.


Serial LCD Controller
Posted on Monday, April 19, 2010   •   Category: PIC


Serial LCD/VFD Controller is a HD44870 based LCD/VFD controller via RS-232. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby such as LCDC.


PIC NIC Ethernet Controller
Posted on Monday, April 19, 2010   •   Category: PIC


PICNIC is a project to add 10BaseT Ethernet controller to PIC17F877, and it can run as an network-enable device. This project is based on tristate's PICNIC product. And I just change the temperature sensor's circuits to improve the precision on A/D convert and add another Temp-Sensor channel.


USB - LCD with PIC Microcontroller & FT232
Posted on Monday, April 19, 2010   •   Category: USB Circuts


USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby. Such as LCDC... The firmware are based on David Potter's Serial LCD/VFD Display, but I almost rewrite the entire code.


DTMF Decoder with LCD Display
Posted on Monday, April 19, 2010   •   Category: AVR


The DTMF decoder 2 is a useful tool used for decoding DTMF (Dual Tone Multi frequency) generated by telephones. The decoded digits are viewed on a 16x2 LCD screen.
