if LCD is in parallel mode:
remove R30, R31, R32
put connections between:
R30/R33 (PC2) to TP_SDO of LCD
R31/R34 (PC3) to TP_SDI of LCD
R32/R35 (PB13) to TP_SCK of LCD
Header Pin7 (PA4) to TP_IRQ of LCD
P8 Pin1 (PA9) to TP_CS of LCD
if LCD is in SPI mode:
same as above, but do not remove R30, R31, R32 (or wires if you use HY28B in SPI mode)
红色线是改SPI模式,蓝色线是改touch screen
