#64747 - RE: ISP cable AT89C51RD2 Responding to: ???'s previous message |
ok my mistake
i want to program AT89C51RD2 with the UART, but the basic question is how to implement it which db9 pin goes with psen, tx, rx, ale when you try to program with FLIP , or anyprogrammer. perhaps the reset is used? sould i use 2 max232 for the 4 lines? |
