AVR-P40-USB-8535 BOARD FOR AT90S8535

There are two ways to program AVR-P40-USB: with ICSP port and with JTAG port. To program via ICSP port you need serial port or parallel port AVR-ICSP programmer dongle (Olimex part # AVR-PG1B or AVR-PG2B). The serial port ICSP programmer (AVR-PG1B) works with PonyProg software by Claudio Lanconelli and the latest release may be downloaded for free from lancos.com. The parallel port ICSP programmer (AVR-PG2B) works with AVR ISP from Atmel and may be downloaded for free from Atmel's website. More: JTAG programming/debugging: AVR-JTAG (complete analog of ATMEL's AVR JTAG ICE) is a development tool for programming, real-time emulation, and debugging for AVR microcontrollers JTAG interface (ATmega16, ATmega32, ATMega323, ATmega162, ATmega169, ATmega128). AVR-JTAG has: JTAG 10 pin connector (Atmel layout), status LED, RS232 connector. AVR-JTAG allows access to all the powerful features of the AVR microcontroller. All AVR resources can be monitored: Flash memory, EEPROM memory, SRAM memory, Register File, Program Counter, Fuse and Lock Bits, and all I/O modules. AVR-JTAG also offers extensive On-chip Debug support for break conditions, including break on change of Program memory flow, Program memory Break Points on single address or address range, and Data memory Break Points on single address or address range. JTAG interface: The JTAG connector is 2x5 pin with 0.1" step and Atmel's compatible layout. The PIN.1 is marked with a square pad on the bottom and an arrow on the top. JTAG signals are: 1- TCK, 2- GND, 3- TDO, 4- VREF, 5- TMS, 6- NSRST, 7- VCC, 8- NTRST, 9- TDI, 10- GND.

RS232 interface: RS232 interface is designed around USB to RS232 converter IC FT232. More information about this IC can be found from the manufacturer's website http://www.ftdi.com. Proper drivers for your OS should also be downloaded from the same internet site. All RS232 modem signals are available around the FT232 IC for connection. RS232 Rx signal is connected directly to PD1 (AVR Tx) and RS232 Tx signal is connected directly to PD0 (AVR Rx).
