Just FYI - deleting the 0xD9 and 0x10 has NO effect on data retrieved from LCD.
Here is modified readcomman I use to test. Works same as readcommd8 to process / retrieve data from LCD.
The important part is - I am using real hardware SPI on Due, no generic I/O SPI as some of the libraries are using.
[code] uint32_t readcommand16(uint8_t c, uint8_t parameter) {
#ifdef TRACE_TREE
TraceTree_EX(1, 1, 0, (char*)__func__, __LINE__ , __FILE__, "uint8_t readcommand8(uint8_t c, paramater ) ");
#endif
//while(1);
// writecommand_cont(0xD9); // woo sekret command?
// writedata8_last(parameter);
writecommand_cont(c);
#ifdef TRACE_TREE
TraceTree_ellipses(1, 1, 0, (char*)__func__, __LINE__ , __FILE__, " writecommand_cont(c); ",
4, "c command ", c, "paramater ", parameter);
#endif
//while(1);
return readdata16_last();
}
