HI, This is sushant,
i have the 3.2 inch TFT LCD with HX8357C controller **broken link removed**.
I have developed a custom PCB using LPC1768, i have attached Schematic for controller and image for Interface Connector View attachment portable_LCDV1_PAGE1.pdf
Change in schematic is RESET pin has been disconnected from MCU RESET and attached to TP10. RS has been misspelled as RD.
the problem is couldnt get is run, the LCD is showing with screen. i have checked library with https://github.com/seanogden/HX8357_PIC32.
i couldnt actually target the problem, also i kind of confused with TFT controller naming, the one i have has HX8375C, but on github or any arduino example code (C++) i have found has HX8357B or D as mentioned.
also while checking SPI read write code, i can see NO read frame, read data is always 0xFF, i read datasheet for HX8357D000/1, it has mentioned 2 serial mode as 3 wire SPI or 4 wire SPI, so i think it may be 3 wire SPI, but i need to know the communication is proper or not.
I am using LPCOPen library, with C as programming language.
At present i am cluless and need some guidance to trouble shoot.
Any suggestion will be helpful,
Thanks sushant
