hi,
i recently bought the pt2262 and pt2272m4 module. while testing i guess i blew both the ICs. i believe so because in the receiver section, without the transmitter part on, VT goes high with all the data pins high. i tried changing the address pins connection to high and low also. but it still didnt change. so i think i burnt the IC before succesful testing.
as for the transmitter part, the /TE pin and the Vss pin is short circuited somehow.
my main objective of the testing was to check if i can use these module for the parallel transmission. so that i can create multiple commands at the receiver side.
from the datasheet of HT12E/HT12D, i found that they can b used for parallel transmission but the problem is its having the latch feature. which is not what i need.
PT2272 M4 has the momentary feature but i would like to have it in parallel version.
does anyone have any idea abt it?
