Only then you can watch how your design works. Time has come to introduce another useful tool, Programmer.
The programmer supports both parallel and SPI programming for your convenience. A powerful window's based GUI facility makes your programming task an easy one. For the u-controller a 40 pin ZIF socket can be used. This programmer circuit can be use to program the 89S series devices and the AVR series devices whichare pin compatible to , like 90S For other AVR series devices the user can make an adapterboard for 20, 28 and 40 pin devices.
The pin numbers shown in brackets correspond to PC parallel portconnector. The ISP-3v0. The main screen view of the program is shown in figure 3.
For the fuses setting consult the datasheet of the respective device. For the auto hardware detection it is necessary to short pin 2 and 12 of DB25 connector, otherwise thesoftware uses the default parallel port i.
I have only included the devices which I have in hand, and verified their correct programming, when I willget the other devices the software will be updated. The memory buffer contains both the code data and the eeprom data for the devices which have eeprom memory. The eeprom memory address in buffer is started after the code memory, so it is necessary the hex file should contains the eeprom start address after the end of code memory last address i.
The software does not provide the erase command because this function is performed automatically during device programming. If you are required to erase the controller, first use the clearbuffer command then program the controller, this will erase the controller and also set the AVR device fusesto default setting.
