Notes on this besp32 lilygo ttgo mini32 16MB esp32 wrover ttgo-t7-v1.5-mini32
https://github.com/LilyGO/TTGO-T7-Demo
Tried boards in arduinoide:
***Had to make my own board (see bottom of doc)
ttgo-t7-v1.4-mini32 and small stuff loads but it wont let me select 16MB of FLASH (4MB max)
X -ESP32 WROVER module with 16MB - just keeps rebooting
To upload code in ArduinoIDE:
Had to set Upload speed to 115200
Also had to set 115200 for Serial monitor
Changed partition scheem to 16MB, etc
For the SD card: MOSI: 23 MISO: 19 SCK: 18 SS: 5
I had to flash a ArduinoIDE sketch on to the board before I coudl use esptool.py. If I didn't it gave an error "A fatal error occurred: Could not connect to an Espressif device on any of the 2 available serial port" OR the serial monitor was still on in ArduinoIDE
esptool.py write_flash --flash_size detect 0x00 retro-go_1.39-pre-dirty_odroid-go.img
Info: $ esptool.py chip_id Detecting chip type... ESP32 Chip is ESP32-D0WD-V3 (revision v3.1) Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None Crystal is 40MHz MAC: 08:3a:8d:23:ae:94 Uploading stub... Running stub... Stub running... Warning: ESP32 has no Chip ID. Reading MAC instead. MAC: 08:3a:8d:23:ae:94
Tried adding a new board to ArduinIDE that coudl handle 16MB: vi /Users/bdash/Library/Arduino15//packages/esp32/hardware/esp32/2.0.14/boards.txt Also did this in platformio: vi /Users/bdash/.platformio/packages/framework-arduinoespressif32/boards.txt
