I have a EasyPIC5 by MikroElecktronika and it works with a dip style not using an in-circuit programmer and am using a 3volt supply in circuit. I’ve easyPIC5 schematic, but in page 4 not clear about onboard USB programmer (no pin number in PIC18F). So, anybody can help me more detail.

It is possible to use external or USB power supply. When using USB port, there is no need for external sfhematic supply; 3. On-board USB programmer with mikroicd support. Its key feature is an ability to upgrade. By downloading a new software, it will be possible to program new MCUs in coming years; 5. PC keyboard connector; 8. DS temperature sensor connector; 9. It is connected to potentiometers P1 and P2; segment displays in multiplex mode; pin connector allows an easy connection of LCD; LCD contrast potentiometer; Select pull-up to enable port pins to detect logic zero easupic5 and vice versa; If a switch is OFF, the appropriate pin does not have a resistor attached.
The same applies to other ports: Graphic LCD contrast potentiometer; Reset circuit; push buttons allow control of every pin on the microcontroller; Touch panel connector; and In order to use the EasyPIC5 properly, it is necessary to go through the following steps: Scheematic the product CD into CD drive.
Do not connect the development system to schematix PC yet.
Install PICflash programmer software to enable a program to be transferred from PC to the microcontroller chip. For detailed installation instructions refer to the PICflash programmer manual. For detailed installation instructions refer to the Installing USB drivers manual.
Has anyone got an Easypic 5 board that is broken for sale? Or info on how to repair it?
Please use one of the USB ports on the back of the PC because these are directly connected to the computer motherboard. You will be immediately prompted whether Windows should search for new drivers update or not. Select the option No, not this time and click Next. Another window appears, click Next and the operating system will automatically find the drivers. After these four steps, your EasyPIC5 is successfully installed and ready for use.
You can read a program from the chip or write another one into it. The product CD provides numerous simple program examples to make your first steps Easy It is designed to allow students and engineers to easily test and explore the capabilities of PIC microcontrollers.
It also allows PIC microcontrollers to be interfaced with external circuits and a broad range of peripheral devices. The user can therefore concentrate on software development only.

Figure 1 illustrates the EasyPIC5 development system. There are identification marks next to each component on a silkscreen, both on the top and bottom.
These marks describe connection to the microcontroller, operation modes and provide additional useful information so that there is almost no need for additional schematics. Figure 1 EasyPIC5 development system.
In order to enable these before programming, the appropriate jumpers or switches have to be properly set. Switches are mechanical devices used to establish or break connection between two contacts.
As for this system, switches are grouped in nine DIP switches. Each group of sschematic port LEDs has its own switch. Each display digit can be individually enabled. Under the plastic cover of a jumper, there is a metal contact which establishes connection when the jumper is placed over two pins. Figure 3 Jumper as a switch Jumper is commonly used as a selector between two schemafic connections via 3-pin connector.
As illustrated in Figure 4, the middle connector pin can be connected to the left or right pin, depending on the jumper s position. Jumper is not placed and middle pin is unconnected. Jumper is placed on the left side connecting middle and left pin. Jumper is placed on the right side connecting middle and right pin. Figure 4 Jumper as a multiplexer. If you use pin microcontrollers, make sure to select the right socket.

All 8-pin microcontrollers use DIP8 socket. Since all packages have parallel connections, it is not allowed to have more than one microcontroller on the board at a time. These are normally used for connecting external peripherals to the schematc or as points for digital logic probe connecting. Some of the easypuc5 are connected to on-board peripherals, such as DS temperature sensor, RS- communication module, 7-segment displays, LCD etc.
Figure 6 System connection. When using power supply over USB cable, jumper J6 should be set in the right-hand position. In this case jumper J6 should be set in the left-hand position. Figure 9 illustrates USB and external power supply circuit diagram. J6 in the right-hand position: Figure 8 Power supply select jumper.
Please refer to PICflash documentation for more information. Figure ewsypic5 USB 2. In the USB programmer section there is the jumper group J These jumpers are used for PGM pin selection. As the Low-Voltage programming mode is not supported by PICflash programmer, this jumper group J10 should remain in default position. Figure 11 J10 jumpers Note: There is no need to reset MCU after programming because it will be automatically cleared by the programmer. When J7 is in lower position, the hardware reset is enabled by pressing the reset button.
Hardware reset is disabled in this case. Since these are not close to each other, there are two on-board clock oscillators.

There are identification marks next to each MCU socket on a silkscreen indicating which oscillator should be used. Quartz crystal is placed in the X1 socket by default. Figure 15 Oscillators Note: The appropriate MCUs have only an internal oscillator and do not use quartz crystal. Refer to the Figure above.
The mikroicd debugger uses on-board programmer to communicate with the compiler and supports common debugger commands: For more information on how to use mikroicd debugger please refer to the mikroicd User s Manual. You can also find it in Help documentation inside any of the before mentioned compilers. In this case, LEDs will display the state of the corresponding microcontroller pin. Otherwise, the LEDs are always off, no matter what the port state is, as no current can flow through them.
Resistors are serially connected to the Schematc in order to limit their current. In this case the resistor value is 1K. As its name suggests it is used for MCU reset. Figure 21 Reset switch circuit echematic. Jumper Eaaypic5 determines whether a button press will bring logic zero 0 or logic one 1 to the appropriate pin. When the button is released, the pin state is determined by pull-up or pull-down port jumpers.
Figure 22 Push buttons circuit diagram. By pressing the button, the RB4 pin is connected to ground via J Accordingly, only when the button is pressed the microcontroller senses a logic zero 0. Otherwise, the pin state will always be a logic one 1.
Accordingly, only when the button is pressed the microcontroller senses a logic one 1. Otherwise, the pin state will always be a logic zero 0. Figure 25 Button with pull-down resistor. Common marking of 7-segment display segments Figure 27 7-segment display circuit diagram. It usually displays messages in two lines, containing up to 16 alphanumeric characters each. The character LCD communicates with the microcontroller via 4-bit data bus.
Figure 29 illustrates its connection to the microcontroller. While a character LCD can display only alphanumeric characters, a GLCD can be used to display messages in the form of drawings and bitmaps.
The most commonly used graphic LCD has the screen resolution of x64 pixels. It consists of two separate foils which form a sandwich structure. It is very sensitive to press so that even a soft touch causes some changes on the output signal.
