    Design for Mini-UPS /w SLA batteries for Modems, routers?

    mini ups Hi, I'm looking to see if anyone has designed something similar to PicoUPS-100 https://www.mini-box.com/picoUPS-100-12V-DC-micro-UPS-system-battery-backup-system Doesn't have to be 100W, can be like 50W. This would be a nice project for us to build!

    Need help in coding a verilog bi-directional port like this.

    verilog bidirectional databus If you look carefully at 3.2355, Cursor E, You will in fact see FRD go low. What baffles me is that when FRD goes low, the Databus gets the value that was shifted out from the previous JTAG cycle so infact the bus is bi-directional. This leads me to believe that...

    Looking for someone to help me clone a USB -> JTAG adapte

    I need help with someone programming the CPLD part, preferably in verilog (vhdl can do as well). Please e-mail me at goldserve1 AT hotmail DOT com for more details and payment. This should only be a few hours work at most! Cheers!

    Need help in coding a verilog bi-directional port like this.

    verilog bidirectional bus Hi Guys, I need some verilog coding help. I am trying to write a state machine that accomplishes what the logic trace below does. USB Data Bus is a bi-directional port USB Signals are command signals into the chip. WR# and FRD# are read and write strobes into the...

    Looking for USB -> JTAG verilog code

    jtag verilog I started to program my own TAP master but find it very hard to fit it into the MAX300E with 32 macrocells. I know it can be done. The specs are an input clock of 24MHZ and the JTAG clock is 500hertz. Anyways, I have the specs of the TAP master in pictures below. If someone can...

    Looking for USB -> JTAG verilog code

    jtag tap verilog I saw that but it is probably not what i'm looking for right? Doesn't this go on the chip and is on the other end of JTAG? Controlling all the boundary scan registers, etc? I'm looking for basically a parallel to serial converter that has a jtag state machine so I can send...

    Does anyone have any info on this USBJTAG design?

    Does anyone have any info on this board from www.usbjtag.com **broken link removed** I want to make my own usbjtag based on this one. Clearly it uses a ez-usb chip and a Altera CPLD device. Does anyone have any Verilog or VHDL code that you think will work?

    How to drive PWM with output voltage swing of 0 to 625mV

    Hi, I am controlling some voltage regulator and I need the output of the uC to be a pwm signal at 2khz + and have a voltage output swing of 0 to 625mV. How do I create that? I'm guessing I need a cap or something like that?
