ATOM Display Latency Checker Firmware

Overview

This firmware is to measure internal latency of display.

Requirements

• platformio Shell command
  • https://docs.platformio.org/en/latest/core/installation.html#piocore-install-shell-commands
• RLE compressed FPGA bitstream
  • You can generate it by running make within a GOWIN EDA project directory. (eda/atomdisplay)
• GOWIN EDA 1.9.8 or above (if you want to re-generate bitstream.)
• Seeed Grove Light Sensor
  • Connect it to the Grove-compatible port of the M5ATOM.

How to run the latency checker firmware.

1. Connect ATOM Display to the host PC and HDMI display.
2. Check the device name of the ATOM Display. (e.g. /dev/ttyACM0 )
3. Modify upload_port and monitor_port linese in the platformio.ini to the device name of ATOM Display.
4. run make at the test directory.
