Want FreeRTOS? Or one of these boards? (also see http://www.renesasrulz.com/community/rx-contest - although that board is 3x bigger and has no sdram, dvi, or ps/2) I have three more blanks, but they run about $135 in parts and stuff plus $50 for the pcb (my cost). I've been trying to finish the initial round of hardware testing before making any more, hence the verilog questions - I don't know if I *can* successfully drive a DVI monitor yet, for example. I haven't tested the PS/2 interfaces yet. Everything else seems to work fine. The FPGA test program, for example, is a FreeRTOS app that has a console command line (FT232R) that downloads the fpga file from my web server into the sdram, then programs the fpga. The backup app reads the fpga file off the microsd (FAT filesystem) for when I screw up and hoze the memory bus. Other minor peripherals: Consumer IR (tv remote) receiver, ambient light sensor, temperature sensor, stereo audio out, wall power voltage monitor (was going to monitor current also, but the design is flawed), second serial port (ttl header). The board has three switching power supplies and runs of USB power *or* 8-16 VDC wall power (although not everything gets power from usb, like the PS/2 connectors, due to the limited current available). Actually, the FT232R remains running if either power is there, so you can power cycle the board without losing the usb connection. It can be reprogrammed using the FT232R (gRX mode) or firmware can be downloaded over the native USB port. When I'm developing, I usually have two USB cables connected to it - one for the console (includes remote reset and mode control) and a second for the USB firmware download path. For my second RX project, I was thinking of a board with an ethernet switch chip (the RX has MII) and a USB hub chip, plus microsd and sdram. That gives you a home firewall/appliance/server box with 2Gb of "disk space" and 64 Mb of RAM. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
