![]() ![]() ![]() NOTE: TFT35 SPI and MCP2515 multiplex a group of SPI1.uncomment overlays=spidev1_2 to release 'spidev1.2' to user space (For example: adxl345), spidev1.0 is used by MCP2515, spidev1.1 is used by tft35_spi.Uncomment overlays=mcp2515 to enable MCP2515 spi to canbus module (Theoretically, it can be multiplexed with tft35_spi and 'spidev1.2' at the same time, but mcp2515 needs strong real-time, it is better not to enable other SPI1 features when using mcp2515).CB1 will automatically identify the HDMI resolution, but if your HDMI screen cannot report the resolution through the EDID normally, we can forcibly specify the resolution of CB1 output by uncomment extraargs=video and set the actual resolution.īTT-HDMI7 resolution = 1024圆00: resolution = 800x480: Uncomment overlays=tft35_spi to enable TFT35 SPI screen.If klipper wants to use UART0 to control the motherboard, we need to set it to console=serial, now klippe can use UART0 as /dev/ttyS0. We can use MobaXterm to connect to CB1 by UART0 and debug. The default value is console=display, This means that the UART0 of CB1 is used as the debugging port by default.set fdtfile to sun50i-h616-biqu-emmc for CB1 eMMC version, set fdtfile to sun50i-h616-biqu-sd (default value) for CB1 normal version.Set as required as shown in the figure below.After the OS writes to the SD card, there is a FAT32 partition named BOOT, open BoardEnv.txt file with Notpad, Notpad++ or VSCode.Set WIFI_SSID as your actual wifi name and WIFI_PASSWD as your actual wifi password, The space character can be parsed normally without additional escape character.After the OS writes to the SD card, there is a FAT32 partition named BOOT, open system.cfg file with Notpad, Notpad++ or VSCode. ![]()
