    GPIB interface design - about active and passive pins...

    fpga gpib The links above were provided in this thread. Somehow they are no longer working. Can someone help please? Added after 20 minutes: Oh well I am particularly interested in IEEE Std 488.1-2003 link...

    help on ASM code for LM35DZ and PIC16F877A

    lm35dz You should be able to find a lot of examples on the web.

    What is the difference between hard real time and soft real time system in RTOS?

    Operating System Hard real time tasks − must complete their processing by a particular deadline. Normally something bad will happen if the deadline is missed. Soft real time tasks - have a preferred completion time. Normally missing the deadline is not fatal.

    New 32 bit Pic micros.

    Wait wait wait... I will wait until Microchip release their next generation of 32-bit processor. Like Bob said, too many erratas to worry about I afraid. I think Microchip is kind of "publish them fast but don't fix them fast" type.

    Communication PC, not use MAX232!

    Some transistors + resistors could do the same... Google it.

    neural network for speech recognition

    speech recognition code Vista!!! Windows Vista has Speech Recognition support. Added after 9 minutes: Sorry... You meant hardware! Well have a look at Microchip's dsPIC. They provide library for Speech Recognition and a free compiler in the form of Student Edition.

    Voltage measurements on an IC pin

    Depend on the characteristic of the signal you're measuring... also the quality of the multi-meter playing a part as well.

    How to make a PIC18f programmer that can be burned from MPLAB?

    pic programmer Go to Microchip website and look for PICKit2... it's a great programmer and the price is low!

    Help me to find a good tutorial in PID from scratch to high level

    pid controller tutorial Also look for some PID voltage controller from Microchip application notes.

    problem with serial data transfer using hyperterminal

    perhaps this is not related, but I think it worths a shot. Try other program like TeraTerm...

    PIC16F877A :serial communication problem

    micro c usart_write Did you check the manual to see what actually is done inside Usart_Write() ? The reason I ask is it was not clear if that function check TMIF before writting to TXREG.
