Hi to all I have used the keil USB mass storage device example on my LPC2378 board. The firmware works fine until I connect to the USB another board. If the boards are more than one, only the firs works. Moreover if the PC boots with the boards yet connected, only one works. If I connect the second the PC crashes. Did someone know how to solve this problem ? best regards ---...

Hi all! The Microchip PIC16F87XA has got a MSSP module. Bits SSPM(3 downto 0) in SSPCON register configure the mode of the module. For I2C operation the following options are available: 1111 = I2C slave, 10bit addressing, with START/STOP interrupts 1110 = I2C slave, 7bit addressing, with START/STOP interrupts 1011 = I2C firmware controlled master mode (Slave idle) 1000 = I2C master ...

I use Cypress EZ-USB FX2 for a data transmit system, FX2 in Slave FIFO mode, with FPGA as the master. I write proogram to transmit data from the PC to FX2.(direc is OUT) The problem is , when I set IFCONFIG = 0xC3 in firmware, which means Slave FIFOs executes on internal 48MHz clk source, it works well. but I need to set IFCONFIG = 0x43, which means Slave FIFOs executes on external clk s...

Hi, I have written a firmware for cypress ezusb fx2 usb controller which does the basic loop back operation. Following are my endpoint configuration. EP2 ---> IN 512 Double Buffered EP4 ---> OUT 512 Double Buffered EP6 ---> IN 512 Double Buffered EP8 ---> OUT 512 Double Buffered EP4 is connected to EP2 and EP8 is connected to EP6. Loopback works fine with EP4 and EP2 but fails with EP
