I just received my arduino pro mini 3.3v (http://www.sparkfun.com/products/9220
) and i am trying to upload the "blink sketch" to it.
First i tried it with my usb ttl programmer hooked up like this:
ttl rx - arduino tx
ttl tx - arduino rx
ttl 3.3v - arduino vcc
ttl gnd - arduino gnd
ttl rst - arduino DTR
board selected: arduino pro or pro mini (3.3v, 8 Mhz) w/ atmega328.
but i keep getting the error
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
Then i tried hooking it up to a arduino without chip and reversing the rx and tx but nothing works...
