Is it possible to design a micro current isolate power like that? Vin = 10V, Vout = 5V, 20mA < Iout < 50mA, and the most important efficiency must above 70% . I want to use a PFM DC-DC controller to achieve that. Anybody can give some suggestions on choose the PFM DC-DC controller? how about...
I have installed mplayer MPlayer-1.0rc1 in SUSE 10.0,but it doesn't support GUI successfully,so I have to open multimedia files in shell by the command "mplayer /path/file name"
lcd 1602
That's right,such as controller KS0074,this chip has all three kinds interface type with MPU: serial, 4-bit bus and 8-bit bus.The same as you say,there is a serial to parallel register in the chip,but this register not simply as the same as 74164,we need to know serial communication...
hello everyone.I'm running into this problem. When I try to simulate a filter in multisim2001 power pro and use the OPAMP NE5532,there is error(no result),when I change the NE5532 for other OPAMP,the filter will work well.Anybody could tell me this is why?Is it a bug of multisim2001?The one who...
lcm1602 datasheet
thanks kovic.
"There are two kinds of data operations - one is 4-bit operations, the other is 8-bit operations."(from:page 16,datasheet of splc780)
clearly,this controller also doesn't support serial interface.
1602 lcd datasheet
Tnks for giving directions.
I have searched datasheet of KS0065 in google,but I found KS0065 doesn't support serial interface mode,only 8-bit interface and 4-bit interface.
Hi all.
A friend of mine delivered a LCM(LCD Module) to me,type is 1602.but i haven't gotten its datasheet,also my friend doesn't have any ways to resolve.
I have examined it with multimeter,and got some informations,look its picture:
1＝R1 left，2＝J1=squareness pad，3＝R5 right，7＝K，8＝A
R2 left=R3...
