Hi Guillem, Every register is 16-bits. It is a good sign that you can successfully read the STATUS register and the GENERAL_CONFIG register. Can you measure SDA and SCL during the write sequence to the DPOT_POSITION register and share a screenshot so I can verify that everything looks correct. Your assumption is correct, the total 16-bit write can be split into two uint8_t arrays. Best, Katlynne Jones
