gdey0213b74 122x250 4 gray - martinberlin/cale-idf GitHub Wiki

• Size: 122 * 250, 2.13 inches
• Controller: SSD1680Z
• 4 gray mode: Implemented. Use setMonoMode(false) to check it out
• Partial update: works but needs to be adjusted. Is being executed at the moment in a place in RAM that is 50px below expected, making a copy of the contents above (Don't use for now)
• RES value: 3 Ω

Note that new models that are added from Good-Display.com will be now entitled Good-Display in the Wiki to put them in a closer place in the menu.
