Generic e-paper (e-ink) panel driver for ESP-IDF, exposed through the standard esp_lcd panel interface. Adding a display is one descriptor, adding a controller family is one file. Ships SSD1680 support and the 2.9" GDEY029T94 panel, with full and fast partial refresh.
Driver for Chipsea CS1237 and CS1238 24-bit differential ADCs (weigh scales, load cells, bridge sensor). Features full PGA control, flexible sampling, scale calibration, temperature sensing, and offset diagnostics.
Point-to-point UDP datagram transport for ESP-IDF v6.0.x. One socket, one peer, one stream: a 12-byte header with sequence number and session, strict validation of every received datagram, zero-copy send and receive, and a receive timeout that never ends early. No tasks, no callbacks, no buffering, no retransmission: it reports loss and restarts, you decide.
