any one can change STM32F103 code for NCS1.9?

user106325

Hello,

i've nRF5340-DK,  3 wire SPI oled model.

any one can change STM32F103 code  for NCS1.9?

the oled can light on, but no show text, maybe SPI recv Font incorrect.

the H code i've do change,  not sure if it's correct.

// #define OLED_SCL_Clr() GPIO_ResetBits(GPIOA,GPIO_Pin_0)//SCL
// #define OLED_SCL_Set() GPIO_SetBits(GPIOA,GPIO_Pin_0)
// #define OLED_SCL_Clr() gpio_port_set_bits_raw(sclk.port, (gpio_port_pins_t)BIT(sclk.pin));
// #define OLED_SCL_Set() gpio_port_clear_bits_raw(sclk.port, (gpio_port_pins_t)BIT(sclk.pin))

// #define OLED_SDA_Clr() GPIO_ResetBits(GPIOA,GPIO_Pin_1)//SDA
// #define OLED_SDA_Set() GPIO_SetBits(GPIOA,GPIO_Pin_1)
// #define OLED_SDA_Clr() gpio_port_set_bits_raw(mosi.port, (gpio_port_pins_t)BIT(mosi.pin))
// #define OLED_SDA_Set() gpio_port_clear_bits_raw(mosi.port, (gpio_port_pins_t)BIT(mosi.pin))

// #define OLED_DC_Clr()  GPIO_ResetBits(GPIOA,GPIO_Pin_2)//DC
// #define OLED_DC_Set()  GPIO_SetBits(GPIOA,GPIO_Pin_2)
#define OLED_DC_Clr() gpio_pin_set_dt(&dcdc, 0)
#define OLED_DC_Set() gpio_pin_set_dt(&dcdc, 1)
 		     
// #define OLED_CS_Clr()  GPIO_ResetBits(GPIOA,GPIO_Pin_3)//CS1
// #define OLED_CS_Set()  GPIO_SetBits(GPIOA,GPIO_Pin_3)
#define OLED_CS_Clr() gpio_pin_set_dt(&cs1, 0)
#define OLED_CS_Set() gpio_pin_set_dt(&cs1, 1)
 		     
// #define OLED_READ_FS0()    GPIO_ReadInputDataBit(GPIOA,GPIO_Pin_4)//FS0
// #define OLED_READ_FS0()    ((struct gpio_driver_data *)fs0.port->data)
#define OLED_READ_FS0()        spi_rx_one_byte()

// #define OLED_ROM_CS_Clr()  GPIO_ResetBits(GPIOA,GPIO_Pin_5)//CS2
// #define OLED_ROM_CS_Set()  GPIO_SetBits(GPIOA,GPIO_Pin_5)
#define OLED_ROM_CS_Clr() gpio_pin_set_dt(&cs2, 0)
#define OLED_ROM_CS_Set() gpio_pin_set_dt(&cs2, 1)

    Hi,

    I'm not sure I understand what your question is, or what code you are referencing.

    As far as I can see, STM32F103 is a microcontroller and not a OLED display. 

    Is the code you have posted part of nRF Connect SDK or did you write it yourself?

    What did you want us to change?

    Best regards,
    Jørgen

    Hi,

    thanks，

    At first I had no clue, i don't know where to start.

    but now,  i've slove it,  use spi,

    &spi3 {
        compatible = "nordic,nrf-spim";
        label = "SPI_3";
        status = "okay";
        sck-pin = < 0x2a >;
        miso-pin = < 0x2e >;
        mosi-pin = < 0x2b >;
    };
    static struct gpio_dt_spec dcdc = GPIO_DT_SPEC_GET_OR(DT_NODELABEL(dcdc), gpios,{0});
    static struct gpio_dt_spec cs1 = GPIO_DT_SPEC_GET_OR(DT_NODELABEL(cs1), gpios,{0});
    static struct gpio_dt_spec cs2 = GPIO_DT_SPEC_GET_OR(DT_NODELABEL(cs2), gpios,{0});
         
    Best regards
