v3.5.1 Patch Release
CYD35C (3248S035C) Pin Mapping Fix
Fixed incorrect pin assignments on the 3.5" capacitive touch build target that caused CC1101 SubGHz radio to fail. If you're running a 3248S035C board, update immediately.
Changes
- CC1101 chip select corrected from GPIO 21 to GPIO 26 on 3248S035C (GPIO 27 is backlight, GPIO 26 is speaker pad — speaker disabled for SubGHz)
- NRF24 chip select moved from GPIO 4 to GPIO 21 to avoid conflict with CC1101 TX enable
- E32R35T gets its own splash screen watermark
- Flash instructions updated with CYD35C board and correct version
- All version references updated to v3.5.1
