AT89Sxx Base Board
The board is based on the AT89S51, AT89S52, or AT89S53. This board uses STK200 for program loading and includes the serial port at the STK200 header. When I need to program the MCU and need a serial comunication, I do not need to plug and unplug the connector. Because I am using the USB to Serial ISP programmer. Then with the STK200, we must built the parallel programmer STK200. This parallel programmer STK200 can also be use for AVR programmer. This is the reason for the new design.![]()
