tlfong01 fongtoy ft2077 troubleshooting notes



































Now I am checking the write 2 byte signal waveforms.  Everything looks OK.


    EepromcCommandWrite      = 0x02 
    EepromStartAddressUpper1 = 0x03
    EepromStartAddressLower1 = 0x00

    TestDataByte55           = 0x55


 # *** Write 2 data bytes at address 0x0300 ****

    while True:
        spiEeprom.xfer2([EepromcCommandWrite, EepromStartAddressUpper1, 
                         EepromStartAddressLower1, TestDataByte55, TestDataByte55])

.END
