valumi 1.3

A tiny crypto price ticker for the Waveshare 1.47" ESP32-C6 boards: live prices and charts from OKX, set up and controlled from your phone through the ticker's own web panel. One firmware for both boards, the plain ESP32-C6-LCD-1.47 and the ESP32-C6-Touch-LCD-1.47.

New in 1.3

• Plain board colours fixed. The ST7789 panel now also has its own gamma-correction table loaded at startup.
• New chart fill. One gradient across the chart, cut off by the line: bright under the peaks, dim in the troughs.
• Smoother animation. No more flicker when a page lands.
• A ticker with a single coin keeps polling its price. Before, the price went stale after the first fetch.
• Settings survive a rollback even when a newer firmware had saved fields this one does not know, and saved settings that cannot be read at boot are no longer overwritten.
• Web panel fixes: a coin added while another change is queued is no longer removed; the page waits for a restart properly; wrong firmware files are named as such before upload; a refused save puts the controls back.

Settings carry over when updating from the panel.

Install

Easiest: in your browser. Plug the board into a computer with a USB-C data cable and open the valumi web installer in Chrome or Edge. Click Install valumi, pick the board's port, and wait about a minute.

Or by hand, with esptool and the valumi-1.3.bin below:

pip install esptool
esptool.py --chip esp32c6 write_flash 0x0 valumi-1.3.bin

Updating

A ticker already running valumi updates from its own panel: Device → Firmware update, with the same valumi-1.3.bin. That keeps all settings. Installing over USB starts fresh.

If the board's port doesn't show up, try another cable (many carry power only), or hold BOOT while plugging it in.

Then

The ticker shows a QR code for its own Wi-Fi hotspot, VALUMI-XXXX. Join it with your phone, tap Sign in to network (or turn mobile data off and open http://4.3.2.1), and add your Wi-Fi. The ticker joins your network and shows its address and panel password; afterwards the panel is at http://valumi.local.

• Touch board: swipe between coins, hold a finger to pause, picture follows the board's orientation
