Hi, thank you for your replay. i connect the chip and C232HM as follow:
my Chip ------------C232HM
(1)CS# ----- CS (2)SO ----- TDI (3)WP# ----- (not connected) (4)VSS ----- GND (5)SI ----- TDO (6)SCK ----- CLK (7)HOLD----- (not connected) (8)VDD ----- 3.3V
Wherein did I make my mistake? how do i connect it? can you give me a tip? thank you
You should *always* connect *all* input pins of an IC. Connect 3 and 7 to 3.3V.
