Hello, Forget all that mess. I got the stepper(s) tested and the coils match up but the red and green wires for the first coil need to be switched for the TMC2100 drivers that are on the Replicape. Although, they, the people behind the Replicape, are leaning on updated boards, one fellow said

[beagleboard] Re: Li-Ion instead of Li-Po?

Li-Po is a Li-Ion, just it has jelly/jello like chemical solution instead of liquid which makes them more leak resistant. These cells often have a temperature dependant resistor to both ID the battery (capacity) and reduce overcharging danger. Li-Po / Li-Ion cells should not be charged when

Re: [beagleboard] 1-wire not working

1w didn't work in that version of Linux. It works in 4.14 if you enable the dtb file in uenv.txt. So I think you'll have to update. It looks like it should support multiple devices, but we're only using one, so I haven't tried. Good luck. -j On Mon, Nov 18, 2019, 10:28 AM Fohnbit wrote: >

Since you have a custom power supply, I would look there first. Needs to be 5.0V plus or minus 0.25 Volts, with no spikes or transients that would ever go above 5.5V or below 4.5 Volts. The BBB's on board PMC is very serious about protecting the BBB. --- Graham == On Monday, November 18,
