I am using a bioimpedance measurement kit which has ARM7 lpc 2148 processor inside, a graphics lcd display and a bioimpedance module integrated into it. first i have to display the characters in the display and then write the code for calculating all the bioimpedance parameter values and display the corresponding values on the display. next i have to display all the calculated bioimpedance parameter values in the keypad scanning that is if i am pressing one of the keys in the keypad it should display one of the values, then if next i am pressing another key , it should display another value...etc. After this, i have to display a waveform..This is a summary of my project.
what my problem is that in the graphics lcd program , the characters are getting displayed on the graphics lcd but the values which are being calculated are not getting displayed on the graphics lcd. i showed the code to a person ,he is saying its because of addressing problem because of this, the values are not coming to the display. he said to check the processor diagram and check if SDA and SCL signals are coming to the display or not. i have attached the base programs which i am using for both graphics lcd and keypad scanning here(GLCD.doc and key.doc).. and i also have attached the program which i have done for graphics lcd(final.doc)....please check....
