18. Please run LCD_ID_readreg.ino to verify your non-standard wiring. Paste the defines to a Forum message.
19. OPEN-SMART Shields have different wiring to regular Uno Shields:
Edit mcufriend_shield.h: #define USE_SPECIAL
Edit mcufriend_special.h: #define USE_OPENSMART_SHIELD_PINOUT
Edit MCUFRIEND_kbv.cpp: #define SUPPORT_8352B
Edit utility/mcufriend_shield.h: #define USE_SPECIAL
Edit utility/mcufriend_special.h: #define USE_OPENSMART_SHIELD_PINOUT
Edit MCUFRIEND_kbv.cpp: #define SUPPORT_8352B
20. OPEN-SMART Shields can not read LM75A on a Mega because there are no SDA/SCL pins next on AREF header.
Uno: LM75A on pcb works. Difficult to add external I2C devices when Shield is plugged in.
Uno: All use of SPI bus should use SPI.beginTransaction(), SPI.endTransaction()
Leo: I do not support USE_OPENSMART_SHIELD_PINOUT_LEO
Mega: Old boards do not have SDA/SCL on AREF header. Only external I2C devices on COMMS header
Due: MAX809 Reset chip interferes with 3.3V RST on SPI header. Manual reset for Upload / Run.
