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!
