#183888 - RE:TTL to 232 cable? Responding to: ???'s previous message |
Hi Oliver!
The Evaluation board has an original cable that I connect in X2_1 and X2_2, the eval board has also this connections and works ok. For reasons of my application, I don't can drive the reset input. I force the reset disconnecting and connecting the power. This works also in the evaluation board (I put PSEN to GND and disconnect the power and connect again. The bootloader works). Perhaps there is some problem with 485 driver but I have also installed this driver in the eval board and... it works... |
