JPE15 can be a 2 pins connector, with a 5. Suggestions of any kind to allow me to improve the circuit are well accepted.

Such facility should be anyway not necessary, as the PIC has an internal circuit with the same function. This board have been 774hc541n for PIC16F and tested with it and on this page we’ll always refer to it ; the circuit should be anyway suitable for mentioned microcontrollers, too 18F4x2 and 18F4x8with the following notes: Set, in the following order see also figure E1: Copper side layout at dpi KB Components side layout datashret dpi KB Components placement silkscreen at dpi KB Electrical schematic at dpi KB Components placement and track view at dpi KBor, still good quality, Components placement and track view at dpi KB Why so many dip-switches?
Circuit’s characteristics and description Let’s now go on with the possibilities of this Development Board. References to a particular switch of the dip-switch Sx will be made as Sx-n, the same convention for connectors JPx.
The images you can see below here are or dpi images. To remark 74hv541n, in the case of the crystal, the waveform on the Osc1 and Osc2 pin is datasgeet sine wave or a distorted sine wave.
PIC 16F16F If you wish an answer, please write your address. Here the printable dpi image.
Let’s now describe the main characteristics of this circuit: JPE8 respectively, as homologous elements of the two sets are connected together pin by pin. Of course, if you own an datawheet trace oscilloscope, you can do without it.
PCB layout printing In the images below you can see the circuit’s layout and 74bc541n to place components. Hoping I have been useful to you, just to me to wish you a good work! Copper side layout at dpi KB Components side layout at dpi KB Components placement silkscreen at dpi KB Electrical schematic at dpi KB Components placement and track view at dpi KBor, still good quality, Components placement and track view at dpi KB.
While designing this circuit I tried to realize a versatile circuit and, in the same time, I also pursued the possibility to mount only the components dafasheet wish, making this D. You are the visitor n. Remark on how to identify switches and connectors’ pins References to a particular switch of dqtasheet dip-switch Sx will be made as Sx-n, the same convention for connectors JPx.
If the port should 74uc541n uses as an input, such current should be supplied by the circuit connected to RB3, and this could change the signal level. As already said, take care to avoid any conflict among supply sources. Another example in the figure 4 at dpi – Components placement and tracks layout; the dpi version, printable with good quality, can be reached at the section layoutbut it requires to be loaded a longer time than the dpi version, apt to ratasheet a look at it.
S5 – Connection to programmers It is a 6-ways dip switch related to the programming. There is anyway a mA fuse; see warnings about the fuse on the components’ list.
You can see there that the bottom side layout soldering sidewhen exposing the board to the light for the photoetching, must be placed with the printed side in contact with copper. Set, in the datasjeet order see also figure E2: According to it, the proper configuration of switches must be choosen. Back to Home Page E-mail address. Microchip and PIC are registered trademarks. It is a good practice, if not really necessary, after programming, that is during the normal working, to insulate the PIC from the programmer opening all the switches of S5.
With the browser you could have problems with the images’ size, while, as an instance, Windows TM Imaging TM should print them in true size.
You can save just from this page the dpi images on your hard disk or other media choosing “Save OBJECT with name” and print them later with your browser or other programs. The fuse should stop the input voltage to the when the current sunk is higher than the nominal value of the fuse; the fuse should protect the external power supply in input to thebut has no effect on the supply connected through JP8 or JP9; besides, in case of short-circuit, it is not sure at all that it is able to avoid damages to the chip, the programmer, possible external circuits and to the power supply itself, whichever connector J1, JP8 or JP9 this one is connected to S7 inserts the LED D3, which shows the presence of supply to the PIC, whereever it comes from from thethrough S1, from JP9 through S5 or from JP8 through S6 The LED D4 shows the presence of a voltage between the pins 1 and 2 of the connector JP8; when S and S are closed, that supply is the one feeding also the PIC from thethrough S1, or from the programmer, through JP9 and S5, or from JP8.
