Hi I'm trying to connect a 29F032 flash memory on a S12XDP512 to store data. I wish to preserve single chip operation. I do not need to extend the memory size...
David, If you can accept the time penalty involved, there is no reason you cannot attach the 29F032's address, data, and control lines to port pins on the S12,...

There are several things to consider in attaching LEDs to port pins: First, the amount of current to acheive a given brightness varies greatly over different...
... The previous responses concerning pin current seem correct to me. The one consideration not yet mentioned is power dissipation for the entire package. As...

... My favorite is to connect VCC (+5) --> 470R --> (A)LED(K) --> Gnd, then connect a GPIO pin from MCU to the Annode (between R and LED). I use this for a...
Recently I switched to a new computer running XP. I am having a tough time communicating P&E parallel HC12 BMD bebugger. It keeps giving me communication error...
If you are now running XP, you need a fix from P&E which stops XP from polling the parallel port and changing the data port values in the process. The fix is...
