It is released as a plugin that should be purchased from our store. It works pretty fast and also supports dozens of new OCR recognition languages. Does anyone know what the reset pin is on this MCU? It looks like 66f489 - My Tuyaconvert setup that successfully and reliably flashes cesmart and teckin sp-20s but this guy doesn’t seem to play ball. I hope by holding down reset on the mcu it will work. thoughts?Īll my research for people converting these to Tasmota has turned up a bunch of people afraid to brick it.
There appears to be documentation for TuyaMCU on configuring the registers for the set points. Seems at least someone flashed with serial at least once. The Inkbird module that the tywe3s sits on has 6 pins.Īlso seems like a similar model exists without the tywe3s.ĮDIT: I have gotten it flashed with tasmota by unsoldering the tyw3s and back together. Those 6 pins have direct continuity to the tywe3s's pins 1 GPIO015 - Only grounded through resistor r26 (value 102) as far as I can tell 2 GND - continuity to nearby GND test pad 3 EN - seems to pull up with heating LED 4 VCC - continuity to nearby 3.3V test pad 5 TXD0 - Pin4 of HT66F489 (PB7/STP/RX/AN1/SSEG27) 6 RXD0 - Pin5 of HT66F489 (PB6/STCK/TX/AN0/SSEG28 per data sheet)įrom my research, that means it should be the standard TuyaMCU 108(Rx) on GPIO1 and 107(Tx) on GPIO3. I have Weblog 4 on and can see TYA sends but no TYA messages received.
