I just started reading about VHDL and i would like to be suggested a complete tool. I don't own any FPGA hardware to test and see actual results and until i do
i would to work with simulations. Searching through the web i found alteras' Quartus II web edition which is free and plus it includes...
Unfortunately SKM53 is not available at stores like sparkfun or Adafruit. Now after searching for a while i found two gps modules which i thing suit my needs. The first one is EM-406 and the second is mtk3339. Both have similar characteristics but the mtk3339 has better accuracy and better...
Hi, i'm trying to find a gps module to use with a uC but i don't know which one is the best for me. It's going to be used in an automotive quadcopter.
Here is a list with a few modules i found:

Hi, i'm using this uC and i'm dealing with a strange problem... I'm building a led globe and it's working great, i'm using 2 contacts for the VDD(5V) and VSS(GND) on a disk made of PCB. So there are wires which make the contacts on the disks' rails and my problem is that for a moment there must...
Hi, i'm using a microcontroller and 3 MAX6956 to control 50 leds. I'm turning on and off the leds without delay but there is a flickering. I'm sending 27 bytes to light on all the leds and 27 to turn them off. There shouldn't be any flickering because theoreticaly the speed is set to 400kbps...
In that case i could even use a battery for the pic. But how can i improve the contact??
I think i could use two metal brushes, it's metal so there will be conductivity and they would be just elastic enough to make a continuous contact, plus many 5v and gnd contacts for each.
Building a LED GLOBE - problem with transfer
Hi, i'm trying to make a led globe as a project. It's similar to this and i have make a big part of the construction. My problem is the transfer of the electricity. I'm using two contacts as a 5V and gnd. I havent installed the leds and the uC yet...
I need to control each one of the 50 leds the way i want. I found some PNP driver ICs such as UDN2981A and TD62783 but i need more equivalent in case it's hard to find these.
Hi i want to use a pic microcontroller to control an array of 50 leds. I'm using two ULN2803 ICs to control the anode and cathode of the leds but
i'm having problems with my schematic because ULN2803 is a NPN transistor array and i can only sink the voltage and not supply it. Is there any PNP...
I chose this connector because of it's shape, i can turn the connector without losing connection. I might use a power jack or a switch and turn it on after i plug it.
Hi, i have converted an old computer power supply to a lab supply and my question is this.
There are many 5Volt red cables, so if i want the maximum amps on 5V do i have to connect all the 5v cables together or i could use only one??
