Both read and write cycles need the CS to be used otherwise the chip won’t know it is in use. "width": "240px", The chip is controlled with three pins; WR, OE, and CS. "product": { } When push-to-on switch S1 is pressed, IC2 generates a 50ms pulse, which is given to the program pin 18 of the ZIF SOCKET through switch S2. But never fear, for I is here, and included in these project files is not only the assembler, but a custom Compile.bat file that will launch the compiler, and pass the correct parameters to compile your program. ":hover": { Now insert the EPROM chip into the 24-pin ZIF socket and slide switch S2 as per EPROM. "margin-left": "-20px" Thus, our software utilises a custom read function that takes in individual characters, puts them into a buffer, and then checks for a terminating character.
