Hello everyone,
board consume too much energy when the acc wakeup and start to measure the tilt.
in Stop Mode : 5 uA
in Wake up : 280 uA
MCU setting for INT pin belong to acc : No pull up-down and rising-edge trigger
for CS pin push-pull and no pull up-down for MCU and for acc is pull up disconnection.
Is this current normal for operation according to code below
dev_ctx.write_reg = platform_write;
dev_ctx.read_reg = platform_read;
dev_ctx.handle = SPI1;
