I need to use interrupt service in my application, but I don't know what control registers need to be configured, and how an interrupt service routine (ISR) gets invoked. Can you please take external interrupt INT2 as an example to show how to program an ISR? Thanks.

I was wondering if you could point me in the right direction. I erased the flash, and compiled and load the first application via JTAG. I ran the first application without flashing the second and expect it to erase itself, but in fact after reset, it restarted the first application again. I have made the following assumptions about the process: 1. ...

The problem was the ldr image did not contain an Interrupt Vector Table at the end. Because of that, the ldr image failed to run after being loaded from flash to on-chip RAM. Can you please advise why? Thanks a lot.

In a MPLAB project, how do I eliminate the startup function from the lib in order to use my own startup code? I tried to delete the Library Search Path from the project build option, which I thought was the way to exclude it, however, the execution still starts from the default startup, and my startup was not invoked.

I realized that the dsPIC has 30 MIPS speed, however, the datasheet also states that it accepts DC to 40 MHz external clock input. My question is, if we use 40 MHz external clock oscillator as clock input, what will the CPU speed be, 40 MIPS or 30 MIPS?

My project manager asked about a standard communication link between Devicenet and .NET instead of our in house program. So I searched online and this new site is what I found. Could you give me pointers to sites that will get me started?

I downloaded Cadence Allegro Free Physical Viewer v16.x from Cadence website and installed successfully. However, when double-clicking the program, I noticed that only the cursor blinked once, the program did not launch. I have tested on both desktop and laptop with Windows XP, the same issue occurred. I'm frustrated. Is there any solution?

Usually, pressing F8 on a tipical Windows PC after BIOS starts would get the machine into boot modes selection window. However, this approach does not work on this machine. I have been searching the internet for the answer, however, there were not any satisfactory answers. Someone says that change Windows boot.ini file, that's not what I like to do. I hope someone here could provide a simple ...

Microchip dsPIC30F4012 was chosen for our application. According to its reference design, we used 7.3728 MHz crystal to generate system clock 29.4912 MHz. I noticed that UART communication works reliably, while CAN communication does not. Can you explain why and advise any suggestion?

After upgrading VisualDSP++ from v4.5 to v5.0 with Update 3, I converted my project that was built with v4.5 to v5.0, every time after building, there was a warning message something like

Trying to load an executable built for 0.0 silicon to a 0.1 silicon target. Continue? Yes (button) or No (button)

Even though it is not a big deal but do you know how to eliminate that message?
