    Need help to learn the LPC interfacing

    LPC :-< Hye all, I'm trying to learn the LPC interfacing. But i'm quite blur with the concept. anyone could simplify the concept of LPC in term of receiving and sending the data. FYI, i'm trying to establish the communication between my MCU and the chipset.. thanks for advace.

    active low or active high?

    active low active high I wonder which one is better for designing using MCU? AL or AH? any comment

    Mutiple 7 segment in long range

    So the RS422 is a hardware interface..the code inside MCU just same like standard UART?

    Mutiple 7 segment in long range

    Brian: Ok ..I got your point..What Actually I worried is I use the phone line as my medium for connectivity between PIC...So just using simple UART can get this job done.It is right? I read an article, they use the RS422 0r 485? So how this protocol can be implement if just use 18f452. Is it got...

    Mutiple 7 segment in long range

    betwixt: You said chain them...So this mean we need to two usart module at same time..I'm I right?

    Mutiple 7 segment in long range

    so, If I want to use the I2C protocol to control each of disply...Is the signal enough to transmit the data? If not, how do I design such that all the MCU got the signal..This scenario I use a MCU for each disply. 1 Master 5 slave. for distance about 100metres

    Mutiple 7 segment in long range

    neroburn Hello all, How could I implement mutiple display using PIC. The Display got 1 master and 5 slave. If we number display in master, the slave should be same number. the problem how to make if the range of between display is long. and I want to minimize the wiring and port using. Please...
