    Hyperlynx: Assigning S-paramter models to capacitors

    I've downloaded a *.s2p model for a capacitor from the manufacturer. I'm trying to assign it to a cap in Hyperlynx board-sim but Hyperlynx only gives me options to select an *.ibs file. Directories are setup correctly, other models in those directories show up. View/Edit touchstone tool can...

    Decoding CANbus messages

    I think its the opposite. CAN does not have a "master" slaves send data periodically. This of course all depends on the vehicle and their CAN implementation. 1st thing would be to google the sh*)& out of that vehicle and see if somebody has decoded the messages. You can certainly get a CAN...

    Synchronizing to SPI frames on PIC32

    I have a master device that spits out 256 byte SPI messages (with some delay in between messages). The SS pin is pulled low at start of transmission and goes high at the end. The slave needs to acquire the entire message but also be able to discard a message if let's the slave processor was busy...

    A math problem / challenge (PIC32)

    Not following you 100%.... I could have used speed as a float, having Speed = 1 (increment every frame) Speed = 0.5 (increment every other frame) Speed = 2 (increment twice per frame) etc.... To do this on a microcontroller I decided to avoid using floats and 1/16th resolution is plenty. Thus I...

    A math problem / challenge (PIC32)

    I'm trying to come up with a simple function to do basically frequency division / multiplication. This will be written in C running on a PIC32, but doesn't really effect the basic math. Inputs to the function are: - Integer variable "Frame" that increments on an constant time base. - Integer...

    PIC development board with CANbus?

    Hello, I'm looking for an inexpensive development board with Microchip PIC (or dsPIC) and a CANbus transceiver. Ones sold directly by Microchip are a bit pricey (DV250501 is $165, DV251001 is $239). It needs to have a PIC that supports CAN not SPI_to_CAN type of interface. Any thoughts? Thank...
