Hi,
I am using EM357 controller which has inbuilt ARM3 cortex processor.
I observed problem while writing on internal flash of EM357 through bootloader application from external flash.
Investigating it further it is observed that this problem observed below supply voltage of 3.1V & above...
Re: graphical LCD interface approch?
Thanks Sumit,
I am thinking about MC68EZ328 for LCD interface.It has may high end features which I dont require.
The only reason for thinking about it to reduce cost of LCD.As COG LCD module have controller inside glass & its price is high.
Thats why...
Hi All,
I am using monochrome LCD(240X128 pixels) in my design & have below 3 approch for interfacing LCD.
1)Microcontroller+external graphical LCD driver+LCD(glass of 240X128 pixels)
2)Microcontroller + chip on glass LCD(240X128 pixels)
3)Microcontroller with inbuilt graphical LCD...
Reversal of voltage.240V/50Hz need a circuit which can differentiate phase & neutral.
If phase & neutral are connected with reverse polarity(ie neutral in place of phase & viceversa) circuit should detect this fault condition.
Thanks & regards

Hallo All,
I want to detect phase neutral reversal in single phase system which dont have earth connection.Can anybody suggest circuit for the same.

Hi,
Please suggest me LDO reguator having current limit upto or greater than 300mA,Vin = upto 40V, Vout = adjustable & it should be low cost

Hi,
U can use MAX1776 from maxim 0.75$.But I dont understand what problem face wit 2A peak current.Are u working on GPRS mode.
Regards
tramp
Thanks Paul for ur reply.
I got the methode after searching.It can be done through menu view->workspace panels->pcb->pcb list
In this toolbar select appropriate layer,select all designators & applymodification to all.

Hi,
I am designing PCB through altium DXP 6 & I want to change font,hight & size of all component designator strings on PCB.How I can do this in this software?
Thanks & Regards,

Hi,
Thnx for ur reply.Its difficult for me to uderstand the process from this document.
How I can make code level design entry in pspice?
I am trying anathor option in Time Domain nalysis & parametric sweep option.In which I am varing voltage source V1(Vsin in Pspice library) from 140V to...
Hi,
I have to simulate circuit attached in PDF file such that ,with respect to source V1(band 135V -150V in steps of 1V) I have to monitor o/p at R6 in time domain.How can I do this in pspice?
What is the use of secondary sweep in DC sweep analysis?
Did anyone have tutarials to understand...
Thanks max0412,
Plese tell me the process of doing paramertic sweep in pspice.ie how did you bring that r7{VAR} in curly bracket.Can we get Vin Vs Vout or R7 Vs Vout grahph in pspice simulation?
Thanks & regards,
tramp
