Description
hwd ver 1.0 that has Meshtastic support is obsolete.
I am requesting a separate firmware target for newer Elecrow CrowPanel Advance 4.3/5.0/7.0-inch boards using the STC8H1K28 controller ver 1.4 and 1.5 possibly as low as ver 1.2.
Hardware tested:
- Product/model: Elecrow DIS02170A 7"
- Printed board revision: 1.4 and 1.5
- SoC: ESP32-S3-WROOM-1-N16R8
- Display: 800×480 RGB
- Touch controller: GT911 at I²C address 0x5D
- Board controller: STC8H1K28 at I²C address 0x30
- Radio: SX1262
- SX1262 NSS/CS: GPIO 8, without a GPIO 0 jumper {now direct plug in}
The existing V1.0 Meshtastic target appears to support older hardware using a TCA9534 at address 0x18 and LoRa CS on GPIO 0. Replacing that target could break V1.0 panels, so I recommend retaining it and adding a separately named target for the newer STC8H1K28 revisions.
A test build for the newer hardware is working successfully. Confirmed results:
- Meshtastic UI boots normally.
- GT911 touch works.
- STC-controlled display brightness and sleep/wake work.
- Retention of screen timeout and screen calibration data after reboot
- Previous ESP_ERR_INVALID_STATE/I²C error 259 messages are gone.
- SX1262 transmits and receives using new GPIO mapping physical GPIO8 is now GPIO0 for SX module CS
Compatibility may extend from approximately V1.1/V1.2 through V1.5, but each revision’s STC address and GPIO mapping should be confirmed before listing the complete range as supported.
I have a working source diff and test firmware available and can provide serial logs or test additional changes.
I am working on further firmware improvement for this board.
