FTDI FTD2xx driver problem with DLP-2232PB device
Hello all! I use the DLP-2332PB for development of the data acquisition device. Using the internal A/D converters of the PIC I would like to sample the incoming analog signal with the rate of 20MHz(per single channel)-1kHz. The PIC-side code was written using CCS complier supplied with the device. The host-side ... 18 Feb 2006 14:49

PIC Ramps
Morning I was wondering if anyone had any pointers on Ramp generating on a PIC? I have four channels that are on consecutively, they are provided from another PIC, I need to code a further PIC that will take these binary inputs and turn them into slow start/stop channels, the rise and fall being over about a s... 7 Feb 2006 14:08

Control of AC outlets?
Cliff notes: How do i use a PIC microcontroller to turn on/off AC outlets? (whether they be part of an existing power strip or a custom panel) What alterations are needed to be made to the outlet? Long version: Hi, I'm a college senior computer science major, and am currently taking a course on embed... 7 Feb 2006 18:19

Optrex F-51852 LCD initialization
Hi , LCD is connected to Renesas M30626 as extended memory, unfortunately i can't get it to display anything. Connection is probably right, as the LCD is answering to "status read" and also fills some commands. I got voltage converter to run, but contrast regulator and bias voltages are not running. Strange, that... 7 Feb 2006 09:56

8051
HI all, I am trying to implement a 8051 based RTOS. Now I have to write a context switch function. I think that , copying all the neccesarry registers without pushing on to the stack works , do you think is this a good idea? Also what stack size is suitable for my RTOS ? (I think 64 byte is ok)... 3 Feb 2006 06:01

Help.....DSP on ARM9 or ARM7!!!!
Dear Friends, In my design I need to develope a DSP algorithm on one DSP processor and then to interface same with ARM which is handling all the peripherals. I am thinking if my DSP algorithm can be implemented on ARM or not...so need you help. Right now I am using evaluation board of Texas DSK, so taking the ... 10 Feb 2006 12:07

Overclcok AtmegaL
Hi, I am going to overclock Atmega16L to 12MHz. I can do that when the JTAG header is attached. However, when it is detached, the program seems to be not working. I have tried to shut down the power of the emulator and it still works when the JTAG header is attached. I do not understand why this strange case hap... 31 Jan 2006 06:26

RTOS port for LPC2214
Is there a FreeRTOS.org or any other free RTOS port available for the LPC2214 (Olimex boards LPC-E2214 && LPC-H2214) ? Thanks. VG ... 29 Jan 2006 09:50

VU meters on LCD
I am having difficulty displaying nice VU meter on a character display, right now I have allowed for 8 segments per channel, which I may make into 40 as you get 5 dots across per character. Now the issue is the bars and very jumpy, either showing a couple or all of them.... I sample the audio every 1/10s an... 29 Jan 2006 00:24

RS-485 Troubleshooting
Hi, I am using Rabbit development board which has separate ports for RS232 and Rs485. Right now i am using a single port both as RS232 as well as RS485. The port works fine for RS232 signals but for RS485 signals, the differential output is not proper.I think there is some problem with the differential voltages. ... 27 Jan 2006 12:18
