thanks Benj always the right adviser gives the right point that has not been thought about. now I see that this kind of Display has no drive componenets just it has sonly two components 1 smd transistor & 1smd DC blacker capacitor. thanks again for making me be happy for my weekend looking forward h...

dear Benj
I have my communications with my suppliers can you kindly say to me what is it that not equal to EBM001
I sent you a copy my new design which I added a main loop
that is not important The only thing I want is to get the Display running
with regards

Dear Benj here is the details of the Display I am using topic 1.44´SPI 128*128 v1.1 Pin connections Id 1 Vcc +5v 2 GND GND 3 CS Chip slecte 4 RESET RESET 5 AO AO 6SDA SERIAL DATA 7SCK CLOCK PULES 8 LED BACK LIGHT/ LIGHT EMITTING DIODE And all the mentioned connections are made regarding to data show...

Thanks Benj I will check my computer by my computer expert this week but PIC16F1937 is bought from Matrix multimedia so it must be the display unit , if its not in the same protocol as EBM 001. Hope it is find out I will report it to you as soon as I Find the result ok or (not ok) with regards Nasim

Dear adviser I tried to get the display showing the inserted data, I designed one more the same kind of circuit as my last project I did make the change as I received the last information to make change in timing the display to one second (No display action ) The reason that I made a new design unfo...

thanks fc7 is working perfict.

dear advioser I have finished my project of driving a motor & Displaying the information in a EMB001 it works in my laptop ok but when it installed in pcb with what I have the equivalent gLCD (1.44´SPI 128* 128 V1.1 it dosem´t show nor it starts the display the crystal for clock pules is a 20 Mhz th...
