[Question] Check model S3 working or not. #472

hoangtridung commented 2 months ago

In my place, I can only buy one of 3 model: ESP32-S3: N8R2, N8R8 or N16R8. https://shopee.vn/Esp32-ESP32-C3-ESP32-S3-WiFi-Bluetooth-Internet-B%E1%BA%A3ng-ph%C3%A1t-tri%E1%BB%83n-Type-C-k%C3%A9p-B%E1%BA%A3ng-l%C3%B5i-ESP32-C3-DevKitM-1-ESP32-C3-MINI-1-ESP32-S3-DevKit-C-N16R8-N8R2-N8R8-i.148048328.25082540763?xptdk=a69d8e82-b912-41c1-8686-ceb42d1b221a

Is it possible work with this firmware? PS: What about model: ESP32-C3 mini ?

The N8 build will work with those as it just won't use the SPIRAM

I flash the sample board (S3 N16R8 ) by command line:

_esptool.exe -p COM14 write_flash 0x0 Faikin-S3-MINI-N4-R2-bootloader.bin 0x8000 partition-table.bin 0xd000 ota_datainitial.bin 0x10000 Faikin-S3-MINI-N8.bin

Wiring to Daikin as:

(+5V) → HV( Shifter) Pin2 (TX) → HV1( Shifter) → LV1( Shifter) → GPIO44 Pin3 (RX) → HV2( Shifter) → LV2( Shifter) -->GPIO43 Pin4 (+14V) → DC-DC Regulator → VCC Pin5 (GND) → DC-DC Regulator → GND ___ LV <-- 3V3

And I can control almost feature on my Daikin, except for the powerful mode and preset. I test with Daikin model FTXS25EVMA and FTXS50EVMA. The minor problem: sometimes I cannot type anything to change the config on Web UI.

Thank you for your effort ! Do you plan to implement it on the C3 module in the near future?

Missing powerful mode is a known problem of FTXS. It looks like Daikin doesn't support it either; so probably there's no solution.
