EVC2 Beta Software

Release 1.0.0.10

  • Fixed an issue with IR35201/ASP1405I which would result in 2x higher output voltage than expected
  • Added preliminary support for IR35204
  • Requires firmware 0005 (or you get UsbIfVersion error)

EVC2 1.0.0.10: https://1drv.ms/u/s!Atmpv-6qHr_6s_Q_CroTXcUvUPhbdw?e=VCpRlj

Older versions below:

Spoiler

Release 1.0.0.9

  • Requires firmware 0005
  • Split I2C device configuration into one per device for easier maintenance
  • Enabled I2C write support
  • I2C device support list:
    • ASP1405I
    • IR35201
    • MP2888
    • uP9512
    • NCT3933U
  • UART support is still limited
  • Removed due to an issue with IR35201/ASP1405I on some configurations that would set output voltage to 2x requested

EVC2 1.0.0.9: Removed

First release 1.0.0.7

I successfully flashed the new firmware and was able to communicate with the evc2 over usb. However, with the new firmware I no longer get readings on the oled display. When plugging the same oled display into my other evc2 module (running the old firmware), the display works fine. 

Is anyone else having this problem?

In the release notes for firmware 0004 it mentions "Temporarily disables the OLED display"

Can we already use the hotwire feature? it's killing me to stare at this thing and not be able to use it hahaha

New software uploaded, see the top post.

Yes, it works. Check the end of this video for an example: https://www.youtube.com/watch?v=ohMSwZRtA8o

  1. Measure resistance between FB and VOUT to get R1
  2. Measure resistance between FB and GND to get R2
  3. Measure the voltage at FB which should be = VREF
  4. Connect SRCx to FB
  5. Connect VINx to VOUT
  6. Enter R1/R2/VREF values under DAC1 in the EVC2 software
  7. You should now be able to modify the voltage. I'd recommend starting with a small positive value which would decrease the output voltage.

Thank you so much! great info and well explained!
I'm having some trouble running the new software however; i've tried flashing the new firmware a second time but still get the  UsbIfVersion error and some .net framework error popups. on windows 10 and not really sure how to proceed.
Thanks!

It's because the software and firmware version doesn't match, 1.0.0.10 software requires firmware 0005. You can double check that the software version is correct under file properties of EVC2.exe. If it is, it would mean the firmware didn't flash properly for some reason.
