[RBBX] Cant Connect to ESC #188

Closed trashmaster9000 closed 8 years ago

trashmaster9000 commented 8 years ago

hi,

i set up the rbbx box to change settings on my ESCs. with my Atmel ESCs it works fine, but with my Silabs ESC (Turnigy 120A-HV-OPTO v2) i cant connect to the ESC. i tried all 3 Firmwares for the RBBX.

with a arduino nano and the 4Way-Interface FW (D Silabs BLH Bootloader) it works fine.

How do you connect the ESC with the box? Servo direct?

trashmaster9000 commented 8 years ago

yes, i connect the Servo plug (the short one for programming) direct to the box. i also connect 5v to 5v on the servo connector.

i tried all 3 firmwares (Bootl. 4way-if, Bootl. 4way-if servo direct and C2 4way-if)

4712 commented 8 years ago

If you use the servo port then only servo direct hex would work. But servo direct might fail with this specific ESC. So I would suggest to modify the box input scenario (increase R8 eg.) or to use another MCU pin (PINC5) as used for C2 interface connection.

i replaced R8 1kOhm with 10kOhm it works now.

thanks for the fast support.
