hello guys
I'm new here and really need your help!
I'm developing a GLCD oscilloscope project that's been found online (**broken link removed**)
I have finished the hardware part and made all the connections and also tried it with a ready given hex file by the designer and the it worked...
hello guys
i have one question here regarding glcd driver for ccs compiler!
is there any difference in the GLCD.C driver between ccs PCWH and ccs PCW ?
can any one pls post the GLCD.C driver for ccs PCWH if u have?
thank you
if you mean before the PIC , yes because i don't want to set the offset voltage to 0v because in that way the ADC won't be able to read the negative voltage!
anyway my point is, if the offset voltage is 2.5v and fluctuating up and donw with the AC voltage of the signal, does it affect the...
i didn't understan what u mean here!
the output of my circuit is from a preamplifier circuit and then low pass active filter which has low impedance! it's a bipolar signal with a positive value above 2.5v and below 2.5v represented as negative voltage! it's like DC is carrying AC signal but the...
hello guys
i want to feed an analog bipolar signal (that has negative and positve values) into ADC of a PIC whic only receives positive values!
so i had an amplifier which bias the output signal into half of the supply voltage which means that if the supply voltage is 5v then the reference...
GLCD types
i'm using PIC18F2550 with C language , i want to make a glcd oscilloscope project! i know it's difficult for me but i found code online and i want to try it then learn from it! i have a project must be done which about displaying heart sound signals on GLCD! that's why i want to try...
Re: GLCD types
thank you wp100 for your help!
that's exactly what i wanna do now, i wanna use ready made code so that i learn from it as a beginner!
one more thing,
in a project i have seen, they used AGM1264f glcd model, i didn't find that model in my area! i have jhd 12864e model, both are...
Hello guys
i have simple question for those who used graphic LCD!
i want to program PIC to display real time analog signal on GLCD!
i found two types of polarzed type GLCD, transflective and reflective!
can i use anyone of them? in other word, is there any limitation of using any one of them...
Re: glcd interface
oh thank you that's good info for me :)
but i should connect the same pin Vee to VR10k right ?
one more thing, did u connect the LED+ pin directly to the 5v (VCC) or it should be connected to a resistor befor the 5V ?
Re: glcd interface
because as i read in last page of the datasheet that VEE interface into -10V,
i want to know if it's implemented onboard or not? bcz im not getting -10V so i want to know is there something wrong with my connection or not
hello guys
i'm using a glcd on a project, JHD12864e model! when i wanted to interface the glcd to microcontroller i found out that the glcd needs a negative voltage generator on its VEE pin ( pin No.18 ) of -10v for the GLCD driving! this model JHD1284e glcd might not have the negative...
