Hello
Need some information about using Broadcom AEAT9955 magnetic encoder
After repatly reading data sheets and application note about i want to try programming the device with an Arduino uno instead of their prommer and app based on stm blue boards.
This device contains and permits many types of spi connections.
my interest is about to change de default resolution of 1024 counts per rev to 8000 cnts/rev
and align index with A .
For my limited skills about SPI communics. I decide d to use SPI3 protocol only for read and write registers without absolute readings by SSI CRC PARITY etc. because my need is only for an incremental with index.
Yesterday i've tried to create a bit banging method for test with DIN DOUT CLK without CS' because in this case of SPI3 must be held at LOW .
Analog old oscilloscope observation gets me data or address bits are stable during active low clk pulses and the MSB is held low on first clk pulse , whole addresses begins always with MSB at zero as data sheet listings and temporal graphics about ..Not tried to connect it because i've affraid about password on the chip with relative E2 prom settings .
My question is about if with this method have some chances to program it correctly?
