hi, I'm modifying the coding from DE2 board CD -> DE2_demonstrations -> DE2_NIOS_DEVICE_LED. For the firmware of device controller for ISP1362 chip, there got six related coding: MAINLOOP.C, CHAP_9.C, D13BUS.C, HAL4SYS.C, HAL4D13.C AND ISR.C. Where HAL4SYS.C and HAL4D13.C is hardware abstraction layer; ISR.C is interrupt service routine; CHAP_9.C and D13BUS.C is protocol layer; MAINLOOP.

Guys, I recently bought: 1) The Velleman PIC VM111 programmer. 2) The Velleman USB experiment board, (VM110) What I would like to do is to program some firmware into a PIC using the programmer, then pop it into the USB board. Programming and testing the PIC on the VM111 is a well-documented and straightforward matter. However, integrating the PIC into the VM110 board isn't so we...

Hi, I was thinking, some embedded motherboards have an on board LVDS LCD interface. Could I use this to transmit other data than video data? I did a little investigation into this. Seems to me I need to write a custom video driver, and connect the other end of the LVDS to a fpga for which I need to write custom firmware for. The thing that worries me is that I think that the LVDS driver ke...

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...
