This is the serial output (seems as expected):
seesaw started
Version: 24FF
TFT OK!
Initializing SD card...failed!
I'm using IDE 1.8.16
Adafruit GFX Library: 1.10.12
Adafruit ST7735 Library : 1.7.4
Adafruit seesaw Library 1.5.0
I can include "Adafruit_TFTShield18.h" in my code but honestly I don't see where that library came from using library manager .. (is that a clue?)
I have no other shields or peripherals attached.
These defaults seem appropriate based on the documentation:
Code: Select all
#define SD_CS 4 // Chip select line for SD card on Shield
#define TFT_CS 10 // Chip select line for TFT display on Shield
#define TFT_DC 8 // Data/command line for TFT on Shield
#define TFT_RST -1 // Reset line for TFT is handled by seesaw!
Is there something funny about the Metro SPI that I'm missing?
If anyone has any debug ideas, or experience getting this combination of hardware to work I'd really appreciate some help. Thanks so much!
