AVR ISP USB Programmer Circuit ATmega8

Previously shared AVR set of experiments found in the AVR ISP programmer carried out separately version of all materials the same printed circuit board size is small circuit for the USB connection FT232RL used programmer ATMEGA8 based on avrprog AVR Studio, Bascom AVR programs can work with. ATmega8 USB Programmer

ATMega8 first integrated circuit to the programmer to main hex ​​file needed to install

There are RST-Reset, MOSI-Master out slave in, MISO-Master in slave out, CLK-Clock, SS-Slave select, Ucc- 50ma, GND-Chassis for programming on the ISP Output. The datasheet file of the AVR integrated circuit that you will program specifies the legs to which these outputs will be connected. There is everything such as Sprint layout PCB, panel design program installation explanations, etc.

ATMEL Microprocessor USB ISP Programmer

Using the programmer via LPT is no longer suitable for me, so I decided to create a programmer of some kind. Nowadays, it does not make much sense to create programmers via outdated ports. Either COM or LPT, because most of today’s PCs, especially LPT, do not even include these ports anymore. The reason for making this programmer was a certain mobility, because NTBs usually only have USB ports.

This is the connection of a BIPROG supported by a USB-UART (RS232) converter. Below you will find the wiring diagram, PCB and recovery description. The programmer acts as an STK500 device on a virtual COM port. This means that it is possible to connect to software that supports STK500 devices. Support is provided by the BASCOM environment, but probably the best environment is AVR studio 4.

It not only provides programmer support, but also allows to control the “filling” of the registers. The processor’s FLASH memory, the processor’s EEPROM memory, as well as the FUSE and LOCK bits can be programmed. The environment supports almost all ATMEL microprocessors ever produced.

ISP-out programming for the RST-Reset, MO-master out slave in, MISO-Master in slave out, CLK-Clock, SS slave select, Ucc-50mA, GND-Ground’s programs that AVR integrated the datasheet file of the output will be connected legs said.
