schematic of a motor controller circuit using pic18f4331 Can someone help me out with the scematic of the motor controller with PIC18f4331, l298 and a quadrature encoder. I already implemented the motor controller with a pic 16f877a, but later I had to abandon that idea as 16f doesnt support quadrature encoder modules.. I adjusted the 16f circuit diagram for 18f4331 , but It... 5 Oct 2009 06:50

I am looking for docs, tutorials or direct help that will allow me configure Eclipse to compile c code for the arm processor. -----------------------... 12 Oct 2009 01:56
24 Bit, dual channelADC, SPI Slave, 85 DegC (or more) Can anyone point me at something? Not going fast (480 samples/sec). Must be available immediately (going down an oil well just after Christmas). TIA, Bill ... 1 Oct 2009 00:39
Encoder programming Hi folks, Im having great trouble in pic programming and hope someone can help me.Im designing a motor controller circuit using pic 16f877a. Iv got a single ended quadrature encoder (It has 5 outputs - a channel, b channel, z channel, 5v, ground). Iv finished the coding for the motor controller part in mikroc. NowI do... 25 Sep 2009 04:17
Need C source for 64 bit integer math (have 32bit limit on my compiler) I'm using CodeVision C compiler on an AVR. CodeVision has 32bit limitation for integers. I need to do 64bit integer math (32bx32b, 32b+32b). I could reinvent the wheel, but figure this has to be out there in multiple places for free. Any suggestions for free C source for 64bit integer math? ... 27 Sep 2009 12:20
Qualcomm MSM7200 chipset deevelopment board? Hi , My name is Kiran Bulusu and I'm developer working on 3g chipsets. I'm looking for info on how to get Qualcomm MSM7200 chipset deevelopment board. Atleast sort of emulator may be would suffice for now? I couldn't get much info from http://www.qctconnect.com/products/msm_7201.html. Does anyone has any experienc... 18 Sep 2009 16:44
Lauterbach Hello, Are there any regular users of Lauterbachs Trace32 debugger (with a USB connection to the PC ) out there? I have just started using this tool a couple of weeks ago and then I changed user accounts on Windows XP and since then I have been getting the message "Target Power Fail" every time I try to load my PB... 18 Sep 2009 14:29
ARM: JTAG problem on developed ARM board Hi. I designed an ARM7 board with LPC2478 MCU. Unfortunately, JTAG doesn't work like one would expect. I can download code to FLASH, I can start debugging, BUT every time it comes to the first STR instruction I get "Could not stop device" ERROR. When I don't step the code it goes to some garbage address. I ha... 20 Sep 2009 14:00
Processor Selection for SoC Hi, I am looking at selecting a processor for our SoC platform. Currently we use an embedded 8051 core (small, low power, low performance, cheap). For our next project, we need more performance, and we are also trying to create a platform suitable for all future projects. The CPU must be available as RTL (V... 17 Sep 2009 23:52
USB device driver / LPC board I have a LPC2478 board (http://www.embeddedartists.com/products/kits/ lpc2478_kit.php) which comes with a USB OTG port. I will run linux on this board and connect this to PC which runs windowsXP via USB OTG port. I wanted to know if there is any quick way of making this USB communication possible without... 16 Sep 2009 15:12 |
