I have used the ViewTool F107 for initial testing of the two displays

Configurations using FT80x should not enable Ethernet, CAN2 or LED

support. The LCD connector, J28 pin 9, and the upper row of J18 are

also assumed to be unused:

Pin 5 PB13 also used by Ethernet, CAN2, LCD and LED4

Pin 11 PA5 also used by J8 pin 7

|
||||
|
||||
J18 upper row is not used in this configuration. Cannot be used with
|
||||
SPI1. Not used with SPI2 because SPI2 has the same conflicts as the
|
||||
lower row so why bother?
|
||||
|
||||
Pin 5 PA4 also used by SPI1/NSS1
|
||||
Pin 7 PA5 also used by SPI1/SCK1
|
||||
Pin 9 PA6 also used by SPI1/MOSI1 and LED1
|

|

J18 lower row conflicts:
|
||||
|
||||
Pin 6 PC5 also used by Ethernet and the LCD interface
|
||||
Pin 8 PA1 also used by Ethernet
|
||||
Pin 10 PA0 also used by Ethernet and Wake-up button (not used)
|
||||
|
||||
Remapped SPI1 pins are not supported, but that would permit these options:
|
||||
|
||||
PA15/NSS1 also used by LCD
|
||||
PB3/SCK1 also used by USART1 and JTAG
|

PB4/MISO1 also used by JTAG
|

PB5/MOSI1 also used by USART1, Ethernet, and J28 pin 10
