SDI Shield with Arduino uno wifi rev2

PostFri Sep 27, 2019 9:36 am


I'm currently integrating an SDI BlackMagic Shileds on an Arduino uno wifi rev2

I'have issue to detect the SDI Shields. I tried default sketch provided and it's not working.
Each time I start the sketch there are an infinite loop on sdiTallyControl.begin() (regRead32())

I tried those connection with the Shiels :
1) SDA, SCL pinout of the wifi rev2
2) A4, A5 pinout of the wifi rev2
3) 0(RX), 1(TX) Serial port of the wifi rev2 (Adapting code to use BMD_SDITallyControl_Serial
4) SDA, SCL pinout of the wifi rev2 remap physically to the pin A4, A5 of the SDI Shields

The Shield is power by an 12V 1A alimentation.
During the boot the Shileds LEDs 2,3,4,5,6 light up very quickly and than only the LED 1 stay on.

The SDI Shileds is correctly detected on the compture via USB and it's configured in 1080i50 at 0x65 default adress

I tried to run I2C scanner with in the 1, 2, 3 connectivity scenario. The only detected address is 0x60 (even if I remove the SDI shield) which I suppose to be the Wifi module.

Does anyone have idea why the SDI Shiled does not reply over I2C or Serial ?
