Tangoboard wiring #24

Hi Oliver a few, perhaps silly questions!

Just noticed in the connectors.md You have suggested 5 pin connectors, while the Tango board has 4 pin connectors for the Joints. What would be a modification in wiring? (Most external drivers have 6 wire inputs perhaps with 2 control inputs being ground.)
What is the jumpers, for, in the image below? Is it power select?
Is there a sample wiring image for say a 3 axis mill with maybe ,TB6600 or similar and how is the tangnano9k board powered?

Many thanks for your help.

in the future, i will add a GND pin to the stepper-outputs, because i have 'mks servo42c' drivers that need 5V logic power and i like to have all the needed pins on one connector.
With this two jumper , you can switch the voltage on the Input-Connectors between 5V and 12-24V power

Many thanks that makes sense. I could see the jumpers for your external drivers on your tango board short video. I will diagram my setup. Still don't understand how the Tangnano9k is powered and the purpose of the jumpers on the board. Maybe I will look at the schematic and see how it works. Also my test TB6600 drivers take 5v. control signals.

to power the fpga, you can use the 5V pins next to the spi-connector, or for directly via the USB port on the TangNano9K.

Thanks will do a git pull and try. Also doing a write up and wiring for the tango board. as I go along.

fixed, but you can normally ignore verilator errors

btw: your 'verilator' version looks a little bit too old: 'Unknown verilator lint message code'

maybe you have installed 'verilator' via package-system (apt), then you can remove it:

sudo apt-get remove verilator

the oss-cad-suite have it's own in a newer version

I never installed Verilator, I just installed litex

I guess I have to update that. This is all very new to me. Thanks for your help

SCLK -> CLK (SerialClock -> Clock)
CS -> SEL (ChipSelect -> Select)

sorry for the different names :(
