Mini-HowTo
Flashing Turnigy Plush(SiLabs) success, now with tutorial!
here is the new and improved tutorial written by me: http://oddcopter.com/2012/07/18/flas...heli-firmware/
it goes through the entire process of flashing popular silabs based ESCs (not just plush) using two methods. --------------------------------------------original post------------------------------------------- I didnt see any threads on this besides very few mentions in the ESC flashing thread, so i decided id post some info here. I found this thread on helifreak that talks about the BLHeli ESC firmware for SiLab based ESCs. it only shows a Turnigy plush 6A as compatible but the plush series has the same hardware except for the FETs so all plush should work. and as of the latest firmware version, it now has a Multirotor setting, yay! it also requires you to buy a 25$ programmer. but since im cheap, i found this max232 IC based programmer to tryout. i bought my plush 25A late 2011 an they are SiLbas based, so im gonna try this. what do ya guys think of this?! EDIT: here is some more programmer info(the expensive one): http://www.hacksmods.com/2012/05/sil...heli-flashing/ and some openpilot discussion: http://forums.openpilot.org/topic/10...abs-based-esc/ and a parallel port programmer(yikes!): http://silabs.org.ua/sp_en.htm |

this is what im going to try:
VDD/V33 from the scheme can be either from the internal vreg, or an external PSU. that is a Turnigy plush 6A, but my plush 25A looks the exact same except the pads are in the center of the board because the PCB is bigger, so any plush should be good. Also, any ESC with a SIL should work as long as you find where VDD/GND/C2CK/C2D are. |

yeah, so this didnt work out very well. these "DIY" programmers dont work and those pads on the ESC are a @#[email protected]#% to solder onto because they are so small and squeezed between the silabs and a vreg?
![]() anybody know of a way to connect with the pads without soldering? like a clamp type thing? id recommend to just spend the 25$ and get the usb programmer ![]() |

What advantages would their be for flashing a SILabs based esc, isn't the refresh rate already 490Hz? |

i dunno about the servo connector, but i didnt because the Silabs chip is 3.3v(5v tolerant pins) and the servo lead is 5v |

the diy programmer was the issue; i tired the max232 based one and the parallel port one. i got the wires soldered on much easier with magnet wire. i think they didnt work because they weren't supported or something maybe. i kept on getting no connection errors. hopefully the arduino one works better. |
