Tool/software:
I have referred to several posts in this community to connect the Raspberry Pi with the DLP2000EVM.
-The pin map is as follows, and additionally, I have connected VINTF to the 3.3V on the Raspberry Pi.
- The DLP2000EVM is powered by an external power supply (5V 3A).
- The i2cdetect command shows the same results as others, so I believe the I2C connection is fine.
- I have enabled I2C in raspi-config.
- I have added the following lines at the end of /boot/config.txt(in rpi5 /boot/firmware/config.txt):
dtoverlay=i2c-gpio,i2c_gpio_sda=23,i2c_gpio_scl=24,i2c_gpio_delay_us=2
dtoverlay=dpi18
overscan_left=0
overscan_right=0
overscan_top=0
overscan_bottom=0
framebuffer_width=854
framebuffer_height=480
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=458773
hdmi_timings=854 0 14 4 12 480 0 2 3 9 0 0 0 60 0 32000000 3
However, when I run i2cset -y 3 0x1b 0x0c 0x00 0x00 0x00 0x13 i and i2cset -y 3 0x1b 0x0b 0x00 0x00 0x00 0x00 i, nothing changes.
Even using i2cget, it only returns 0x00.
Could you please let me know what might be the problem?
