I recently bought the Adruino Leonardo board (new to Adruino board) to drive TFT 2.2 LCD from Adafruit.
I have connected the Leonardo board in my laptop which is having Windows 7 32 bit V1.4 OS and i am able to see the com port as (COM20). But when i try to upload the examples like TFTBitmapLogo and TFTDisplayText, I am getting below error after a long wait (nearly 3 to 5 minutes).
** This report would have more information with**
** "Show verbose output during compilation"**
** enabled in File > Preferences.** Arduino: 1.0.6 (Windows 7), Board: "Arduino Leonardo" Binary sketch size: 12,252 bytes (of a 28,672 byte maximum) Found programmer: Id = "B¨«"; type = Software Version = . ; Hardware Version = . avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?
I tried using Dlink USB hub in between Laptop and Leonardo board but still i got the same error.
Please provide a solution to resolve this error and upload the example.
The TFTBitmapLogo and TFTDisplayText examples are from Adruino IDE. I tried to upload a example code/program given by Adruino to check at the preliminary level. Since I got the below error, i am not able to proceed further.
avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?
Please help to resolve the error while uploading the example code.
After i re-installed the Adruino IDE and reset the PC and No other COM port except the Board, I am able to connect and upload the code. But when i upload the examples with TFTBitmapLogo and TFTDisplayText, the current display (2.2 inch LCD display - 1480) Flicker with as shown.
I have copied the logo.bmp in SD card and inserted in Adafruit LCD.
I just used the example code (TFTBitmapLogo) as it is with changes for Leonardo as below,
// pin definition for the Leonardo #define sd_cs 8 #define lcd_cs 7 #define dc 0 #define rst 1
I am able to display the image (*.BMP) reading from SD card and display in 2.2 inch LCD using Adruino Leonardo Board connected to PC (via USB cable). Thanks.
I would like to send a .bmp file from a Linux based processor board connected to Adruino Leonardo Board (via USB cable) using a code/program and display the image in 2.2 inch LCD.
Please help to achieve and provide sample code if it is available.
