Custom Board using ATSAM3Sview story

http://forum.allaboutcircuits.com – I've recently made a custom board with an AT91SAM3S chip. The hardware is ready but the chip has nothing inside yet. I need to be able to code into the chip just like coding into any other commercial MCU board (e.g. arduino). I'm going to use the Atmel SAM-ICE over JTAG to interface my board to my PC. Could anyone please share the steps to get started working on the software using Atmel Studio? (Embedded)

mini rant, i broke itview story

http://forum.allaboutcircuits.com – Well, I'm not sure if I broke it or my step down controller just burnt out and took it with... but my nano router is dead! It was the chinese nano router though, so its only a $17 loss, but the week-longer wait for a replacement hurts the most! I thought I bought a TL-WR702N from TPLink, but this is what came in the mail... (Embedded)

Weight activated LEDview story

http://forum.allaboutcircuits.com – Hi everyone! I am looking to build a circuit that will light an LED but is triggered by weight. I would want the light to reset at night. So the light would be turned on when the weight is sensed then remain on even after the weight is removed. Do you have any tips or advice? I don't know where to start! Thanks! :) Have a good day :) (Embedded)

Ebay issue, laugh your socks offview story

http://forum.allaboutcircuits.com – Ebay were having computer issues today. As a result I had an online discussion about the problem with them. Afterwards they copied me in on the transcript. All very good and laudable practice until I read this (my underlining) Quote: We've sent this email to both your private email address and your My Messages mailbox on eBay. (Embedded)

Site Suggestion Posting "token"view story

http://forum.allaboutcircuits.com – Hi Guys ! I am in the process of trying to post a [ long touted ] dissertation and pictures of a Tektronix O'scope I lucked into... In short comment, and uploading several pictures, when I punch the submit button, I get a dialog box that some token or another has expired... Can this be made longer, as it is frustrating to have a post bounced in that manner... (Embedded)

Multiple groundsview story

http://forum.allaboutcircuits.com – The question states the following: Suppose in Figure P1-22 a ground is connected to the minus side of element 6 and another to the junction of elements 2, 3 and 4. Further, assume that the voltage v4 is 5V and v1 is 10V. What are v2, v3, v5 & v6? I know that voltage is a "through" variable measured in reference to ground (which is 0 V). (Embedded)
