0.0 point should be left side on the picture and it seems all numbers reversed

Sermus commented 9 years ago

This seems to depend on screen module configuration. Someone before reported that colours are messed like screen controller swaps bytes in colours. You report inverted coordinate system. All my modules seem to work correct with color and and coordinate spaces.

Anyway, can you send me a photo of how my ui demo looks like for you. Andrey. Sent from my mobile device. 06 мая 2015 г. 20:31 пользователь "alonewolfx2" notifications@github.com написал:

ui demo ?

Sermus commented 9 years ago

Please refer to sample code section of read me file. Find code word UIDEMO )))

Did you manage to run the code in UIDEMO mode?

Can you try to invoke setRotation explicitly and see what happens then?

alonewolfx2 commented 9 years ago

i am using your old code from espressif dev kit. i tried last commit but i didnt make it work. its not working on my device. and i found my screen driver is ili9340(chinese seller said ili9341.) actually its not very different chip. its working adafruit ili9341 library just 2 line change. i saw new commit and hspi.c is different. and new code not working. 

data[0] = 0x48;     //C8       //48 68绔栧�//28 E8 妯��
    //transmitCmdData(0x36, data, 1);       // Memory Access Control for ili9341
    transmitCmdData(0x40, data, 1);          //Memory Access Control for ili9340
    transmitCmdData(0x08, data, 1);          //Memory Access Control for ili9340

how can i work with new code? any suggestion

Sermus commented 9 years ago

Espressif dev kit doesn't have my code for ILI9341. This is another guy's code.

So you're saying that the code from UDK you can make it work with these two lines change, but you can't make my code work with the same change. Did i get it correct?

alonewolfx2 commented 9 years ago

yes you are right.same change not work with your code.

Sermus commented 9 years ago

Hm, it's hard to say why just looking into code. What i'd do in this situation is connecting logic analyzer and capturing the actual SPI exchange. I did a lot of such debugging writing that lib.

firstly you defined cs pin to gpio15 but perfer used gpio4 can i change this? i am using esp-03 and gpio15 connected to gnd with 2k pulldown resistor. https://github.com/Perfer/esp8266_ili9341/blob/master/include/ili9341.h#L43 https://github.com/Sermus/ESP8266_Adafruit_ILI9341/blob/master/driver/hspi.c#L26

Sermus commented 9 years ago

Nop, it uses hardware CS line control which is possible only for GPIO15. If it's connected through 2k resistor (i mean not shortcircuited to gnd) you still should be able to use it as CS.

alonewolfx2 commented 9 years ago

i used 2k2 resistor soo problem isnt it. hmm. any idea ?

Sermus commented 9 years ago

Do you have 15k?

alonewolfx2 commented 9 years ago

i have 10k. i can connect together. 12k is enough?

Sermus commented 9 years ago

yes, it shall be absolutely enough

alonewolfx2 commented 9 years ago

12k resistor seems to solved all problem :) Thank you. its working now. screen orientation is right. also i will push pull request for ili9340 init. or maybe you can?
