Problem connecting Serial LCD.
I hooked Grove Serial LCD v.1.1 LCD23154P to serial port (white connector near the same I2C) mega328P v.3.0. without any shield.
Is that correct?
Then recorded in the catalog of the library of ARDUINO v1.0.4 software next files for serial LCD:
1.Hello! Example, еtс.
2. Serial LCD.h version at 15 march 2012 for arduino 1.0 IDE by Jimbo.we
3.Serial LCD.ccp by Jimbo.we
All files from recomended for Serial LCD v.1.1 LCD23154P from wiki page.
Then ARDUINO v1.0.4 uploaded “Hello! example” file
and got error:
Binary sketch size: 3.830 bytes (of a 30.720 byte maximum)
avrdude: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x55
avrdude: stk500_paged_load(): (a) protocol error, expect=0x14, resp=0x74
avrdude: stk500_cmd(): programmer is out of sync
Serial LCD on nothing only light both leds.
When you connect the 3-axis compas - everything works (without Serial LCD).
What did I do wrong?
