  When I put in my serial port in and try to connect, the program tells me "unable to connect to device: response from device is too short" ... any ideas on how to troubleshoot this for Mac computers?

  HI,
  We are trying to implement a potentiostat, and we came through a design that replicates our desired output provided in
  [ https://iorodeo.com/blogs/news/rodeostat-square-wave-anodic-stripping-voltammetry ], we are new to the potentiostat and trying to implement based on a sample output voltage and current values we have. Thus we like to know how to implement it in your potentiostat in a step by step manner,

  I think darktable would be a reasonable option https://www.darktable.org/

  You can find a list of supported cameras here https://www.darktable.org/resources/camera-support/

  There is some information of camera tethering here https://www.darktable.org/usermanual/en/tethering_chapter.html

  Oh gosh, you are right! I’m sorry for the delay but I was very busy. I have never thought to rotate the LED matrix because I thought I was right with that (otherwise, if not, no LED would have turned on). Thanks very much! I also take advantage of you for another issue. I have tried to load the arena configuration on the SD card but PControl doesn’t let me do that. Have you any suggestion? It seems that the controller doesn’t communicate to the SD nevertheless at the beginning (when the controller is switch on) PControl finds and initializes the SD card. I’m sorry because of all these questions!

  It looks like the RTL8195 has 3.3V IO. The potentiostat shield powers the MCP4261 with 5V. So you are connecting a 3.3V device to a 5V device - I think. I'm not sure if the IO pins on the RTL8195 are 5V tolerant, but you might want to check. Could be related to you issue.

  Note, the MCP4261's could be powered off of 3.3V. They have a pretty broad allowed input range 2.7 - 5.5V. This would require cutting one trace - the one going to the 5.5V on the shield - and rerouting this trace to to the 3.3V pin.

  The spec sheet for the MCP4261 can be found here. http://ww1.microchip.com/downloads/en/DeviceDoc/22059b.pdf
