I am using Da1469x MCU and social distancing project with Wira SDK 10.440.8.6 for our custom board.
Board has LCD with SPI communication and Pixart with I2C communication.
1. In custom board ST7735 LCD spi pins and their control pins are connected to P0_0 to P0_3. The problem is SPI communication is not happening in P0_1(MOSI) and P0_2 (SCLK).
2. If we connect only MOSI and SCLK pins to other gpio pins LCD is working fine only in battery, but if device connects to charge then lcd is misbehaving and not working properly.
3. Pixart needs one GPIO interrupt to run its algorithm.
If pixart interrupt is connected to GPIO P0_5 and P1_5 then fine pixart working properly, but
If the other gpio is connected to such as p0_17 then i am getting continuous interrupt where algorithm won't run properly.
