spi lcd module lcd 12864 factory

This module is engineered for high volume production. It uses a "TAB" (tape automated bonding) or "COF" (chip on flex) style flex tail mated with a "COG" (chip on glass) display. The TAB connector is soldered directly to corresponding pads on your PCB using a hot-bar soldering machine. High volume contract manufacturers will be familiar with this type of construction and its assembly methods. Hot-bar soldering machines designed for prototype, rework or repair of TAB connections are available from equipment suppliers at reasonable cost.

This is an extremely low-power 128x64 graphic LCD display module. It has an integrated white LED backlight that illuminates the display easily in low-light conditions. This display is perfectly suited for hand-held or any application requiring low-power or a very a thin display. It has an integrated controller and the FFC tail is designed to mate with standard 18-conductor 0.5mm pitch ZIF connectors (typical would be Omron XF2L18351A/ DigiKey P/N OR754CT-ND).

Reason: Controller IC ST7565R used on dislay ERC12864FS-1 is hard to source because of the global chip shortage.We now use the compatible IC ST7567S as replacement. The part number is updated to ERC12864FS-1-S7.

ERC12864FS-1-S7 is 1.4 inch white background with 128x64 monochrome black pixels cog(chip on glass) lcd module,ST7565S controller,compact size,high contrast,wide operating temperature,wide view angle,white led backlight,fstn lcd,fpc connection,optional zif connector and led backlight connector.It supports 6800 8-bit,8080 8-bit parallel and 4-wire serial spi interface.

You may wish ERC12864SBS-1 could come with frame backlight without backlight wires ,The part number ERC12864SBSF03-1 should meet this requirment. Except the backlight structure,the other spec is the totally same with ERC12864SBS-1.

ERC12864SBSF03-1 is still not our general product ,we don"t have enough stock .You have to email ([email protected]) our sales to buy samples or orders. Besides the minimum order quantity is no lesss than 1000pcs per order.The production lead time is 5-6 weeks.

ESP chips can generate various kinds of timings that needed by common LCDs on the market, like SPI LCD, I80 LCD (a.k.a Intel 8080 parallel LCD), RGB/SRGB LCD, I2C LCD, etc. The esp_lcd component is officially to support those LCDs with a group of universal APIs across chips.

In esp_lcd, an LCD panel is represented by esp_lcd_panel_handle_t, which plays the role of an abstract frame buffer, regardless of the frame memory is allocated inside ESP chip or in external LCD controller. Based on the location of the frame buffer and the hardware connection interface, the LCD panel drivers are mainly grouped into the following categories:

Controller based LCD driver involves multiple steps to get a panel handle, like bus allocation, IO device registration and controller driver install. The frame buffer is located in the controller’s internal GRAM (Graphical RAM). ESP-IDF provides only a limited number of LCD controller drivers out of the box (e.g. ST7789, SSD1306), More Controller Based LCD Drivers are maintained in the Espressif Component Registry _.

LCD Panel IO Operations - provides a set of APIs to operate the LCD panel, like turning on/off the display, setting the orientation, etc. These operations are common for either controller-based LCD panel driver or RGB LCD panel driver.

esp_lcd_panel_io_spi_config_t::dc_gpio_num: Sets the gpio number for the DC signal line (some LCD calls this RS line). The LCD driver will use this GPIO to switch between sending command and sending data.

esp_lcd_panel_io_spi_config_t::cs_gpio_num: Sets the gpio number for the CS signal line. The LCD driver will use this GPIO to select the LCD chip. If the SPI bus only has one device attached (i.e. this LCD), you can set the gpio number to -1 to occupy the bus exclusively.

esp_lcd_panel_io_spi_config_t::pclk_hz sets the frequency of the pixel clock, in Hz. The value should not exceed the range recommended in the LCD spec.

esp_lcd_panel_io_spi_config_t::spi_mode sets the SPI mode. The LCD driver will use this mode to communicate with the LCD. For the meaning of the SPI mode, please refer to the SPI Master API doc.

esp_lcd_panel_io_spi_config_t::lcd_cmd_bits and esp_lcd_panel_io_spi_config_t::lcd_param_bits set the bit width of the command and parameter that recognized by the LCD controller chip. This is chip specific, you should refer to your LCD spec in advance.

esp_lcd_panel_io_spi_config_t::trans_queue_depth sets the depth of the SPI transaction queue. A bigger value means more transactions can be queued up, but it also consumes more memory.

Install the LCD controller driver. The LCD controller driver is responsible for sending the commands and parameters to the LCD controller chip. In this step, you need to specify the SPI IO device handle that allocated in the last step, and some panel specific configurations:

esp_lcd_panel_dev_config_t::bits_per_pixel sets the bit width of the pixel color data. The LCD driver will use this value to calculate the number of bytes to send to the LCD controller chip.

esp_lcd_panel_io_i2c_config_t::dev_addr sets the I2C device address of the LCD controller chip. The LCD driver will use this address to communicate with the LCD controller chip.

esp_lcd_panel_io_i2c_config_t::lcd_cmd_bits and esp_lcd_panel_io_i2c_config_t::lcd_param_bits set the bit width of the command and parameter that recognized by the LCD controller chip. This is chip specific, you should refer to your LCD spec in advance.

esp_lcd_i80_bus_config_t::data_gpio_nums is the array of the GPIO number of the data bus. The number of GPIOs should be equal to the esp_lcd_i80_bus_config_t::bus_width value.

esp_lcd_panel_io_i80_config_t::pclk_hz sets the pixel clock frequency in Hz. Higher pixel clock frequency will result in higher refresh rate, but may cause flickering if the DMA bandwidth is not sufficient or the LCD controller chip does not support high pixel clock frequency.

esp_lcd_panel_io_i80_config_t::lcd_cmd_bits and esp_lcd_panel_io_i80_config_t::lcd_param_bits set the bit width of the command and parameter that recognized by the LCD controller chip. This is chip specific, you should refer to your LCD spec in advance.

esp_lcd_panel_io_i80_config_t::trans_queue_depth sets the maximum number of transactions that can be queued in the LCD IO device. A bigger value means more transactions can be queued up, but it also consumes more memory.

Install the LCD controller driver. The LCD controller driver is responsible for sending the commands and parameters to the LCD controller chip. In this step, you need to specify the I80 IO device handle that allocated in the last step, and some panel specific configurations:

esp_lcd_panel_dev_config_t::bits_per_pixel sets the bit width of the pixel color data. The LCD driver will use this value to calculate the number of bytes to send to the LCD controller chip.

esp_lcd_panel_dev_config_t::reset_gpio_num sets the GPIO number of the reset pin. If the LCD controller chip does not have a reset pin, you can set this value to -1.

More LCD panel drivers and touch drivers are available in IDF Component Registry. The list of available and planned drivers with links is in this table.

esp_lcd_panel_draw_bitmap() is the most significant function, that will do the magic to draw the user provided color buffer to the LCD screen, where the draw window is also configurable.

Commands sent by this function are short, so they are sent using polling transactions. The function does not return before the command transfer is completed. If any queued transactions sent by esp_lcd_panel_io_tx_color() are still pending when this function is called, this function will wait until they are finished and the queue is empty before sending the command(s).

The 12864B Graphic LCD module is a 128 x 64 pixel LCD display with a blue backlight and white foreground. The display is fully programmable and can display a combination of both graphics and text. It can operate in both parallel and serial (SPI) modes which can be configured by the external pin PSB. In SPI mode only 3 data pins are required to drive this display. No potentiometer is required to set the contrast as this is pre set by the factory to optimum level.
