adafruit tft display setup factory

No retailer can control a manufactured part from a vendors factory. Thats the reason quality retailers have or should have their own quality control or at the very least a customer return policy for situations that fail to meet the specs on products they offer. As I said in my earlier post I would have been happy to use a "working" communications protocol as described in the Adafruit on line literature and that is why I purchased this display. The part is not useable the way it shipped to me in ANY comm scheme. It is defective and should be replaced. I am not set up to rework SMT circuit boards and should not have to be. Adafruit is the middleman and should deal With the manufacturer for this type of a situation.

I am purchasing hundreds of $ in components for my projects and supporting Adafruit because "Adafruit invests time and resources providing this open source design, please support Adafruit and open-source hardware by purchasing products from Adafruit!"

I am sending a copy of this post to your CEO to review this nickel and dime response. I sincerely hope Adafruit revises their policy on returning factory defects.

"Also, the display may come in SPI mode. You can change modes from 8-bit to SPI or I2C with a little soldering, check out the tutorial for how to do so."

we cannot guarantee the mode these come in, or provide customized versions. if you are unable or unwilling to follow the tutorial we link to in the product description, email support@adafruit with a link to this thread and you"ll get a refund for this item.

note that 8080 mode or 6800 mode is based on an old processor but is easy to implement, very fast, and is the only protocol usable to read-back from the display

After all, I connected the display as I always do with 8080 types (of course with 3.3 V) but it does not work. I get a lot of random pixels. All the signals on the scope look correct. There might be a timing problem but I first want to be sure that de display is in the correct mode. If necessary I can reprogram to 6800 mode but (I"m a bit lazy) hope to get the thing

whatever the datasheets for the SSD is what is "correct" for pinning. the display is essentially just the SSD chipset and oled with pins brought out directly (so the jumper labeled BS1 for example == the BS1 pad in the chip)
