Serial Port Professional PIC Programmer

Microcontroller Circuit | By: Diagram mania

  Serial Port Professional PIC Programmer   The PIC programmer project presented here is intended to be used by more experienced developers who already have access to a simple PIC programmer, because the programmer hardware is built around one 16F627(A) or 16F628(A) microcontroller that has to be preprogrammed with firmware. The presented solution uses PC’s […]

Real Time Clock PCF8583

Microcontroller Circuit | By: Diagram mania

  Real Time Clock PCF8583   The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 […]

RCD Programmer

Microcontroller Circuit | By: Diagram mania

  RCD Programmer   I believe that the “JDM Programmer” is cheap and very useful PIC Programmer. However, since “JDM Programmer” cannot control VDD, the algorithm “VPP before VDD” is inapplicable. Programming to the latest device from this reason may go wrong when using CONFIG settings as “Internal oscillator” “MCLR OFF”. These devices are given […]

PWM Motor Driver with MOSFET H-Bridge and AVR ATmega8

Microcontroller Circuit | By: Diagram mania

  PWM Motor Driver with MOSFET H-Bridge and AVR ATmega8   Here is a very simple project of controlling a small DC-motor (taken from an old personal cassette player) with ATmega8. The ATmega8 is having three PWM channels, out of which two are used here. PWM waveforms are fed to MOSFET (RFD3055) H-bridge. Here, direction […]
