I ve just wired everything perfectly tried to upload sketch with ttl usb adapter and i got this: avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0xe0
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xe0

any ideas?

Please show diagram of your connections

Are you sure that bootloader is installed on the board? Because pro mini doesn;t have USB, it can be sold without bootloader

3

Whats the bootloader?

4

the program in the chip that answers to your PC via ttl adapter

5

when i plug the ttl adapter the boards led start to blink with a 1sec delay aprox.

6

Do you press the reset button on the board in the beginning of upload?

7

yes i did that bc ive seen it in a thread but unfortunately it doesnt work

8

hard to tell more without a wiring diagram.

9

ive just wired the pins for uploading any code i mean not even blink works

Draw it !! Or take a sharp photo of your setup in daylight. Post it here.

Please post a sharp close-up photo of the chip on the Mini Pro The text on the chip should be readible; you might have to angle the camera a bit so it becomes readible.

Definitely a wire in the wrong place. My crystal ball told me.

15

Doesn't look like you have connected a TTL-to-USB adapter.

16

i did but unpluged it for u to see better

17

I think you will have to draw a diagram at last... you can draw it on a piece of paper by hand and then take a picture

18

plug it in then retake a photo
