Outputting to mOLED-128 LCD

geometrix

All,

I have downloaded some example code for the mOLED-128 LCD. I am reading some input from the GPS module and I want to output this to the mOLED-128.

I have been experimenting with outputting the value of a variable and I cannot seem to figure out how to do this. Do I need to convert the value stored in the variable to a string and then output the string to the OLED-128? Do I need to write an ITOS subroutine to do this?

Thanks in advance.

Show us how you have it wired and the code you are trying.

Dear Franklin,

Thanks for the reply. I have been sidetracked for the last month and am finally getting back to this.

I have wired the RX and TX pins of the microOLED-128-G1 to P10 and P11 on the Board of Education respectively. I did this per page 8 of the 4D systems microOLED-128-G1 USERS MANUAL. I also connected the the 5V and GND as well (to the 5V and GND pins on the BOE).

I am using code to output characters as shown below, but how do I output the value of X if let's say X=27.58??? I found these code examples on the forum and they seem to work very well with the display. So I have the display working just fine. I am just trying to output values of variables to the display rather than a string character-by-character. This brings me to my next question. Do I need to convert numbers to strings and then output the values of the strings character-by-character?
