    nhanndt The generating rate of the GSM modem is 115200 bps So think about it: how long does each character take to transmit...? nhanndt I don't understand what parameter 1/8, 1/4, 1/2, 3/4 or 7/8 is "1/8" is one-eighth (ie 12.5%); this means that the interrupt fires when the FIFO...

    nhanndt Can i extend the capacity of the FIFOs? No - they are a "hard" part of the Stellaris microcontroller silicon. But you really shouldn't need to - even an 8051 (an 8-bit pocessor with no FIFOs) should be able to cope with controlling a modem! The key is to use a software buffer...

  • Forum Post: Re: Interrupt handlers

    Steve Ling
    In the qs-scope example the interrupt vectors are declared and placed into the vector table in the startup file (startup_xxx.x depending on which dev tools you are using). Possibly this is the link you are missing? For example, here are the relevant lines from the startup_ccs.c file. //*******...

    Andy, First, thanks for the reply. Second, you say that I have to first enable the peripheral as if I should know that already. Every other CPU I have used allows you to write to registers before enabling a peripheral. In fact, if I enable the peripheral first, it's going to be in some default...
