OpenTR6260 PWM Support for Status RGB Strip with Tuya Compatibility

How can I get PWM dimming working on my Tuya-compatible TR6260 RGB strip controller instead of only full-brightness relay-style control?

Yes—TR6260/OpenTR6260 does support PWM, and dimming works once the pins are configured correctly on a recent build [#21725563][#21727114] For this strip, the working setup was GPIO1, GPIO2, and GPIO3 set to PWM with channels 1, 2, and 3 for RGB, and that config worked perfectly on a newly flashed unit [#21727066][#21727079][#21727136] If PWM on GPIO22 does nothing, it was likely an older firmware/build issue; the latest firmware fixed it [#21726568][#21726881][#21727555] If your config keeps reverting or won’t save, use the newer partition file `new_partition_0x6000.bin` [#21725563] Updates are flashed over UART, not OTA [#21725563]

just something AI noticed about this when checking something else:

drv_tinyir_nec.c currently treats the roles backwards compared with the normal IR drivers:

Code: Text
Log in, to see the code

But the rest of OBK’s IR code treats them as:

Code: Text
Log in, to see the code

is this correct and if so, is this an acceptable fix?

Topic summary

Discussion about OpenTR6260 PWM support for a cheap Tuya-compatible RGB strip controller. Initial flashing showed only relay-style on/off behavior and no dimming, plus configuration save issues that were traced to an incorrect partition file; a full UART reflash with the newer partition fixed saving. PWM was confirmed to work on TR6260, but the correct setup is to assign the RGB channels directly to PWM pins with proper channel mapping (GPIO1 red, GPIO2 green, GPIO3 blue; PWM;1 to PWM;3). Earlier firmware versions had PWM/toggle issues, later fixed in updated releases. The thread also covers residual LED glow when off, limitations in the SDK around PWM duty cycle, and later notes about OTA support, UART flashing quirks, and device template submission.
