    PIC 24f16ka102 interrupt and spi problem

    24f16ka102 Hi! I'm having a problem with the CN interrupts on the PIC24F16KA102. The interrupt routines work fine in almost any situation except when using SPI. If I enable the SPI module, the CN interrupts don't work anymore. It doesn't matter which pin is used, i've tried all possibilities...

    clocking problem - special component to drive clock lines?

    clocking problem Hi! I have to design a system with 3 independent fpga cards in it. I have to provide synchonous clock from one source to all 3 cards. The distance from the oscillator to the fpga-s is about 3-4 inches. Please help me out! Suggest any method to do this! The clock frequency is...

    migrating from TMS320VC5507 to TMS320VC5509

    Hello! I would like to get help about changing a processor in a design. My task would be to redesign a product with another dsp. The current setup uses a TMS320VC5507PGE processor, my question is that what technical modifications should be made if i have to change it to a TMS320VC5509PGE? I'm...

    spartan 3e starter kit adc

    spartan3e starter kit adc Hi! I'm a bit new to fpga-s. I need help or sample code (vhdl if possible) for the A/D module. I need a controller that initiates conversion and stores the data in a register or variable. If you can, please help! Thanx!

    Problem with PIC16f876 USART and hardware PWM in Assembly

    Re: PIC USART and PWM I'm using 16f876 and hardware pwm, the code is written in assembly. Every register is set right. I have been using hardware pwm for ages, but i couldn't get it working together with usart!

    Problem with PIC16f876 USART and hardware PWM in Assembly

    Hi! I'm trying to develop a system with two PICs. One receives analog input and outputs serial data with usart to another PIC. That one outputs PWM with a duty cycle according to the received serial data. My problem is that i can't get the pwm to work correctly when using the serial interface...
