ECG heart Moniter

My questions is pertaining to the LCD-08884 - Serial Graphic LCD 160x128 (LCD + backpack). I’m using a FunSparkSerialGraphicLCD library* to communicate to the LCD.

I want to post a running average heart beat (BPM) FIXED position on the LCD. (NOT continuously painting the whole screen with values)

(first this is important!!)

Then I want to dedicate a lower section of the screen to continuously DRAW an input signal (using the drawing functions).

any help will be appreciated!

I see no questions. Nor evidence of your own attempts
