    danirebollo reacted to igor in ESP8266 - Anyone here play with one?   
    Also in this category is the EMW3162.
    Not sure why the ESP8266 gets all the buz, when EMW3162 has ARM core, less expensive than CC3200.
     
    Anybody done a comparison between the CC3200,  ESP8266 and EMW3162?

    danirebollo got a reaction from bluehash in ESP8266 - Anyone here play with one?   
    I am programming a CC3200 embedded system to control a DSP and hosting a web: ESP8266 is not killer of nobody, he's in a completly different league, and CC3200 wins  
    But ESP8266 for IoT toaster or something could be enough and cheap.   Check this thread: https://e2e.ti.com/support/wireless_connectivity/f/968/t/394126

    danirebollo got a reaction from calinp in SSD1289 TFT trouble (init?)   
    Hello! 
    im trying to connect 3.2" ssd1289 TFT LCD with stellaris. I change successfully pins on high nibble from LCD (DB8-DB15) to different ports on stellaris (stellaris only have one full port: B. others have only a few pins and others share pins with jtag or other functions...), and now my problem is print on screen.
     
    I print horizontally arround large side (320) right up corner is 0,0 , and i can tell point to horizontal start (move to the left):  I can move start point to the left, but not to bottom. Always start at top even when i change start register. 
     
    Has anyone managed to control SSD1289?
     
    when I'm at home i put some code of my library.

    danirebollo got a reaction from reaper7 in LCDBPV2 3.2"TFT+TOUCH: Serial 4wire (speed!!) or 16bit parallel control. I2C touch and Backlight   
    Hello! i made this boosterpack some weeks ago! this is the upgrade of LCD BOOSTERPACK V1 ( http://forum.stellarisiti.com/topic/626-ssd1289-32-320x240-tft-16bit-parallel-interface-touch-libraries/ ). Old version only has parallel control, this new version has improved all things: Serial or parallel, i2c drivers for touch and backlight, better layout...
    Unlike LCDBPV1, LCDBPV2 is compatible with any MCU in the market. You only have to migrate some basic code about specific i/o of your MCU and is done!! (you have to do if I have not yet done... but if you ask me for this and i have mcu to develop i can do this).
     
    You can buy on my web (paypal) or on the tindie store
    Check out LCDBPV2 tag on my web: http://danirebollo.es/index.php/items?option=com_content&view=article&id=1&Itemid=1-lcdbpv2&showall=1
    You cand find some videos and other articles.

    For example, this is latest review i made between some MCUs on the market (better view on my web):
    MCU MODE FRAMES TIME FPS LOW LEVEL FUNCTION
    Chipkit MAX32 EHA 300 1.172 255 LATDSET(1<<y)  ;  LATDCLR(1<<y)
    Stellaris Launchpad EHA 200 1.553 128.78 HWREG(SCS_BASE +  ((SCS_PIN) << 2)) = SCS_PIN  ;  HWREG(SCS_BASE +  ((SCS_PIN) << 2)) = 0;
    Arduino UNO EHA 200 4.903 40.8 PORTD|=(1<<y)  ;  PORTD&=(~(1<<y))
    PIC16F877A EHA 200 7.863 25.44 bit_set(PORTLCD,bCS)  ;  bit_clear(PORTLCD,bCS)
    MSP430 EHA 200 11.64 17.18 P2OUT |=y  ;  P2OUT &= ~(y)
    Chipkit MAX32 Serial 50 15.12 3.31
    Stellaris Launchpad Serial 1 0.54 1.83
    Arduino UNO Serial 1 1.264 1.264
    MSP430 Serial 5 14.05 0.35
    PIC16F877A Serial 1 6.681 0.15

    yes!! everything works!!
    as analog device, you need to calibrate LCD touch to work well. Use calibration function (only first time) an later write these values into touch.c
