Support for WA-128128-XLW..

hello @ryood @ryood !! I have the round 128*128 round white LCD ; where I am using ur code "https://github.com/ryood/STM32Cube_Test/tree/master/SW4STM32/Nucleo-F446_u8g2_Test1" to display on it.

I have initialized the LCD as follows and trying to print the characters ;but the LCD is not displaying anything ; Its showing some random dots

`int main(void) { / MCU Configuration--------------------------------------------------------/ / Reset of all peripherals, Initializes the Flash interface and the Systick. / HAL_Init(); / Configure the system clock / SystemClock_Config(); / USER CODE BEGIN SysInit / HAL_Delay(100); / USER CODE END SysInit /

/ Initialize all configured peripherals / MX_GPIO_Init(); MX_USART2_UART_Init(); MX_SPI1_Init(); / USER CODE BEGIN 2 / u8g2_Setup_ssd1327_ea_w128128_f(&u8g2, U8G2_R0, u8x8_byte_4wire_hw_spi, u8x8_stm32_gpio_and_delay); u8g2_InitDisplay(&u8g2); u8g2_SetPowerSave(&u8g2, 0); / USER CODE END 2 /

/ Infinite loop / / USER CODE BEGIN WHILE / while (1) { / USER CODE END WHILE /

/* USER CODE BEGIN 3 */
u8g2_FirstPage(&u8g2);
do
{
    u8g2_SetFont(&u8g2, u8g2_font_ncenB14_tr);
    u8g2_DrawStr(&u8g2, 0, 15, "thanks!");
    u8g2_DrawCircle(&u8g2, 64, 40, 10, U8G2_DRAW_ALL);
} while (u8g2_NextPage(&u8g2));
HAL_Delay(1);

u8g2_SetContrast(&u8g2 , 0x00);     //setting contrast to low..
HAL_Delay(6000);
u8g2_SetContrast(&u8g2 , 0xFF);     //setting contrast to high..
HAL_Delay(6000);

u8g2_ClearDisplay(&u8g2);       //clear LCD...
HAL_Delay(6000);

} / USER CODE END 3 / }`

Can u please suggest where its going wrong. Have attached the LCD display pic as well.

Hello @ryood , How to do this for three wire SPI?

Thank you!!

This project is for SSD1306 and does not work well on SSD1306.

The SPI connection is as shown in this diagram https://github.com/ryood/STM32Cube_Test/blob/master/fritzing/STM32Cube_u8g2_SSD1306_%E3%83%96%E3%83%AC%E3%83%83%E3%83%89%E3%83%9C%E3%83%BC%E3%83%89.png

Here is an article I wrote about this project. (Please use google, DeepL, etc. to translate.) https://dad8893.blogspot.com/2019/04/stm32-u8g2.html

Thank you soo much for the response @ryood It doesn't work for SD1306;How about SSD1327? I have made it intialize with SSD1327 with full buffer

[ryood]

Unfortunately I don't own an OLED SSD1327 and have never used it. If I know anything, I'll post it here or on my blog.

Okay.. Thank you!!
