isp flash microcontroller programmer


Posted on Feb 4, 2014

This ISP Programmer can be used either for in-system programming or as a stand-alone spi programmer for Atmel ISP programmable devices. The programming interface is compatible to STK200 ISP programmer hardware so the users of STK200 can also use the software which can program both the 8051 and AVR series devices. Figure 1 shows the circuit diagram

of the in-system programmer interface, the power to the interface is provided by the target system. The 74245 ic isolate and buffer the parallel port signals. The main screen view of the program is shown in figure 3. Also make sure do not program the RSTDISBL fuse in ATmega8, ATtiny26 and ATtiny2313 otherwise further spi programming is disable and you will need a parallel programmer to enable the spi programming. For the fuses setting consult the datasheet of the respective device.
