_spiSettings uninitialized

Open Pablo2048 opened this issue 8 years ago • 6 comments

Hi Marek. Thank You for Your work, but it seems that I found a problem. In SPI transaction mode there is some initialization of _spiSettings missing in begin(...) method.

Are you getting an error or somethings not working?

I'm trying to port Your library to Arduino ESP8266 platform. My TFT is version with touch panel included, so beacuse small I/O pins count on ESP I have to share SPI between TFT and Touch, so I have to use transactions. I'm actually in testing phase so I found out that _spiSettings are not initialized in .begin() - after studying SPI.h from Arduino ESP8266 there is default setting (in object constructor) for _bitOrder LSBFIRST, but ILI9341 need MSBFIRST.

Hi Marek - fantastic work! I too am interested in a ESP8266 version (my new toy of choice is the Digistump Oak, which I hope I'll be working with for quite some time, and using for quite some projects). I have gotten the basic Adafruit library to work but yours looks far more useable and powerful. I would be happy to send you one if you're interested in looking at it. Pablo, if you're reading, have you had any luck?

Hi ppostuma - well, sort of. I have partially working code, but is way slower than optimized Adafruit variant (AS8).

I have a few ESP8266 myself and was thinking to port the library for it but unfortunately I have no time for it at the moment (other projects in the way).
