Change Microchip's PICREF-4 design for 220V
Hi! Can anyone tell me what is needed to change the design of Microchip's light dimmer (called PICREF-4) to use 220V instead of 120V? http://ww1.microchip.com/downloads/en/appnotes/40171a.pdf Its no problem to change the program for the PIC12c508 - but I need the circuit to work with 220v @ 50Hz. I really... 22 Mar 2006 17:28

Advice neede: Atmel or Philips ARM
Hi Gurus, I am switching from AVR to ARM. Currently, I use an ATmega162 which is running out of code space (16kB) and performance. But I find it difficult to choose between Atmel's ARM (looking at the SAM7S series) and thePhilips LPC2104/5/6 series. I don't need many peripherals (yet). My current design uses an ... 27 Mar 2006 20:18

Suggestions for 3.3V CAN Controller?
Does anyone have any suggestions for a CAN controller using 3.3V? Preferably, with two CAN ports but singles are ok. We are currently using the Oki ML9620, but the lead times have begun to hurt our delivery schedules. Thanks Dave ... 22 Mar 2006 14:51

primeview tft lcd
We want to use the primeview tft lcd (PW045XS1). I looked at the datasheet, but it is very summerary. Does anyone know where I can get more information or perhaps example code of how to use this lcd. I have to make my own display controller in vhdl, but example code in C would be also helpfull. TIA, Frank ... 17 Mar 2006 08:30

HC12 Eval Board M68EVB912B32 Flash EEPROM
Hi: I am trying to use the real time interrupt on the HC12 (68HC912B23 derivative), but my EVB uses a interrupt vector table that is located in the read-only section of the Flash EEPROM. Instead, to program the internet vector table I must do the following (quote from the manual): "To allow the user code to s... 16 Mar 2006 11:42

Parallel Slave Port of PIC18F452
Hello people, I'm wondering if anyone has used the PSP device of the PIC18F452. I want to connect the PIC's PSP device as the master where is initiates reads and writes (in the data sheet reads are defined as reads from PORTD and Write is write into PORTD). As I understand when the PSP device on the PIC18f452 ... 19 Mar 2006 22:05

How to run TMS320F2808 from RAM only?
Hello I?m programming a TMS320F2808 DSP. I?m getting tired of the flash process (the erase and then the write process). What modifications must I make to run all of the code from RAM only so that I only rewrite the RAM contents every time I make a modification? Is it enough to include 2808_RAM_ln... 12 Mar 2006 16:08

Which RTOS?
Hi folks, I am about to emabark on a new development using a COTS PC104 single board computer (probably Arcom Viper) for use in an industrial control system. The PC104 will perform the role of an autonomous serial data acquisition hub with some basic control functions. The PC104 will be installed in a remote loc... 14 Mar 2006 15:29
