I can't get my Arduino Pro Mini clone to sync with the FTDI FT232RL clone. I wonder If I do anything fundamentally wrong.
I use Windows Xp
Programming UNO R3 is no problem
The FTDI seemed to have installed well on Xp
I didn't change anything on the Xp settings
The IDE is set correctly to the Pro Mini 5V 328 version
No other things set in the IDE
Pins names are on FTD / Pro Mini
FTDI
Ardu Pro Mini
GND
BLK
CTS
GND
VCC
---
VCC
TX
---
RX
RX
---
TX
DTR
GRN
This connection is obvious:
VCC >> VCC
TX >> RX
RX >> TX
I also do:
GND >> GND
DTR >> GRN
CTS I either leave open or put on GND. I tried also switching RX and TX.
Do I do something fundamentally wrong or is there a possibility that something is defect?
==========================
There was a way to test the FTDI USB adapter via the IDEs serial monitor, but can't it. What to do that?
Thanks, it didn't work. My FTDI modul is probably defect then. Do I need to have a specific board setting in the IDE? I don't think so, or? As a cross check I did:
Removed the µP from the UNO
Connected the UNO
Short TX + RX
And I got the echo on the Serial Monitor successfully.
Via the UNO I can upload software to the Pro Mini successfully now. However, I had to connect TX-TX and RX-RX. Shouldn't TX connect to a RX?
BTW, I think I connected the FTDI the wrong way round and burned the chip.
