o-m-d / st7735_spi_stm32 Goto Github PK

Hi,

First of all, i really appreciate the effort you have put in creating these drivers. I am doing a pet project to drive st7735 sainsmart 1.8 inch tft using stm32f103c8T6 minimum system eval board off amazon. The following is the pin breakout on that tft. Last 4 are for sd-card and has to be controlled by a seperate SPI hardware. So leave them be for now. I am trying to connect rest of the pins to the stm32 SPI2 as per the pin breakout in the comments for main.c . VCC,GND,CS,SDA and RESET are pretty straight forward but do you know where SCL and RS/DC should go according to your diagram??

GND : Power Ground
VCC : 5V power input
CS : Chipselect for LCD,
SDA : LCD Data for SPI
SCL : SCLK for TFT Clock
RS/DC : Command/Data Selection
RESET : LCD controller reset, active low


CS (SD-CS) : Chipselect for TF Card,
CLK (SD-Clock): SPI Clock
MOSI (SD-DI) : SPI Master out Slave in
MISO (SD-DO) : SPI Master in Slave out
