#105904 - i have tested the hardware Responding to: ???'s previous message |
I have tested the circuit using the simple terminal emulator. connecting the MOSI, SCK, RST to the txd line one by one and the RXD to the MISO output and shorting the second side. the ciruit is able to communicate, I can send ascii data and the recieve is too.
Have you tested the software/hardware to work with the AT89S52? the AT89S8252/53 has a three byte programming instruction set, whereas the AT89S51/52 have 4 byte pgm instructions. vinod |
