This library is delivered with OPENSMART TFT screens.
I have added support for the ILI9326 with the ATmega1284p for my own use
Screen interface is now splitted on PORTC and PORTB
| Device | Bus | Bus |
|---|---|---|
| ILI9326 | DB8 DB7 DB6 DB5 DB4 DB3 DB2 | DB1 DB0 |
| ATmega1284p | PC8 PC7 PC6 PC5 PC4 PC3 PC2 | PB1 PB0 |
It will slow down pixel transfert a little bit but will free I²C interface wich is located on PortC D1 and D0.
Library delivered with OPENSMART TFT screen. It seems to be a copy (with some modification) of an old version of MCUFRIEND library. It is not the up-to-date MCUFRIEND library as the screen doesn't work with the current MCUFRIEND one. Added support for the ILI9326 on the ATmega1284p. The data bus of the display is connected to PORTC.
| signal | port |
|---|---|
| D7-0 | PORTC7-0 |
| RD | PORTF0 |
| WR | PORTF1 |
| CD | PORTF2 also named RS on some shields |
| CS | PORTF3 |
| RS | not used (connected to Reset of ATmega) |
Following is comment in original readme file.
