Rangkaian Downloader/Programmer AT89S51/AT89S52Atmel is a product AT89S51/AT89S52 that quite a lot in the market with a price of less than 20 thousand rupiah. To start learning mikrokontroler type 89S51 this we need a programmer And Rangkaian Downloader. Programmer is a hardware device that is used to enter the machine language program code compilation that we write to in mikrokontroler. Gambar Skema Rangkaian Downloader AT89S51/AT89S52 picture above shows the circuit diagram of the in-system programmer interface, the power to the interface is provided by the target system. The 74HCT541 ic isolate and buffer the parallel port signals. It is necessary to use the HCT type ic in order to make sure the programmer should also work with 3V type parallel port. Skema rangkaian downloader ini can be use to program the 89S series devices and the AVR series devices which are pin compatible to 8051, like 90S8515. For other AVR series devices the user can make an adapter board for 20, 28 and 40 pin devices. The pin numbers shown in brackets correspond to PC parallel port connector. Software ISP The ISP-30a.zip file contains the main program and the i / o port driver. Place all files in the same folder. The main screen view of the program is shown in the picture below. lock and fuse bits Clear/Fill memory buffer Verify with memory buffer Reload current Hex File Display buffer checksum Program selected lock bits & fuses Auto detection of hardware .Following are the main features of this software. • • • • • • • • Read /write the Intel Hex file Read the signature. Therefore. This circuit can then be connected to other circuits to perform certain functions or can be added with other complementary circuit to become a more complete system and has more functions. Rangkaian Sistem Minimum Mikrokontroler AT89C52|AT89C52 AT89S51/52 microcontroller is the latest version than the AT89C51 microcontroller has been widely used today. it is precisely when we study this type of microcontroller. either pin IC and the instruction set and the price is quite cheap. Mikrokontroler tech non-volatile memory of the Atmel Cleaner density is. Important specifications owned AT89S52 Microcontroller: . AT89S52 microcontroller is a CMOS 8-bit microcomputers with 8KB Flash Programmable and Erasable Read Only Memory (PEROM).Sistem Minimum Mikrokontroler AT89C51|AT89C52 The minimum system is AT89C51/AT89C52 microcontroller electronic circuits the minimum necessary to the operation of microcontroller IC. compatible with industry standard microcontroller MCS-51. 0V Working with a range of 0 .• • • • • • • • • • • • Compatible with previous MCS51 microcontroller family 8 K Bytes • In system programmable (ISP) flash memory with capacity 1000 times read / write 4-labor voltage 5.33MHz Internal RAM 256x8 bits 32 channels of I / 0 may be programmed 3 pieces 16-bit Timer / Counter 8 interrupt sources Full duplex serial channel UART watchdog timer Dual data pointers ISP programming mode flexible (Byte and Page Mode) Pinning Mikrokontroler AT89C52|AT89C52 . because the facility program downloads with the ISP (MISO. Of course.AT89s51-52 and AVR USB Downloader Microcontroller T89s51. others = 1). AT89S52 and AVR is an idol among students. via LPT or COM. charging into the ATmega8.technosains. For those who need a filling firmware and more complete information about the USB Downloader please visit http://guru. SCK. RST). BOOTSZ1 = 0. Well now because of technology trends and laptop PCs already left the LPT and COM so more and more difficult to download the firmware into the microcontroller.hex do not forget to set low fuse = EF (SUT0 = 0. Time to play man with AT89s so much easier via USB without hassle and unplug the IC. then fill it to the ATmega8 with firmware usb51. firmware downloader tool is needed. MOSI. BOOTSZ0 = 0.com/ . CKOPT = 0. then use the ISP downloader which is also commonly used for this AVR microcontroller type. others = 1) and high fuse = C9 (SPIEN = 0. Solutions to be overcome with AT89S S-series. AT89s51-52 and AVR USB Downloader Circuit After you finish creating the PCB from the circuit above.
