Test procedure connection instruction:
Test code condition: JME-2 core board + 1T cycle STC microcontroller (51 inner core STC12LE5A60S2) + 33M oscillator. MCU working voltage is 3.3V.
Default IO program connection:
Control line: RS-P3 ^ 5; WR-P3 ^ 6; RD-P3 ^ 7; CS-P1 ^ 0; REST-P1 ^ 2;
Data cable: DB0~DB7 connect in sequence with P0^0~P0^7; DB8~DB15 connect in sequence with P2^0~P2^7; (DB0~DB07 have the option to not connect under 8-bit mode)
Touching control connection: (Connect it when you use it)
D_CLK-P1^7; D_CS-P1^4; D_DIN-P3^0; D_OUT-P3^1; D_PENIRQ-P3^4;
TFT Power: screen power is 2.8~3.3V; Please don't use 5V. (PCB module has 3V stable voltage IC so the input voltage can be 5V.)
Backlight power(LED_A pin): maximum power is up to 3.2V. (Can make series connection with 20ohm current-limited resistor under 3.3V power. Or make series connection with 200ohm resistor under 5V.)
This TFT module is compatible with 8/16-bit data interfaces. Please switch under follow instruction:
For screen-only users, please follow FPC definitions;
For module users, set the 8/16-bit interface via j3 sodering pad at PCB back. Short connect j3 pad module to 16-bit mode, don't connect to 8-bit mode. The module is default setting as 8-bit interface. Under this default 8-bit mode, only use high 8-bit ( i.e. DB8~DB15,DB0~DB7 to ground or pending as no connection). The 8-bit interfaces occupy the IO is 8 less than 16-bit interface, but the speed is lower, while the 16-bit that occupys more 8 IO will be faster.
