I test communication with:


        public void ReadDisplayStatus()
        {
            _data[0] = RDDST;
            var readBuffer = new byte[4];
            _cdIo.Write(false);
            _spiDevice.Write(_data);
            _cdIo.Write(true);
            _spiDevice.Read(readBuffer);
        }

readbuffer is always containing 0. So I suspect a wrong communication with spi … But without analyzer it’s difficult to understand what’s happened !
