Is it possible to change the Baud Rate? I'm running into issues when I go into the component and change the Baud Rate on the Serial Dat

Hey folks,

Would anyone be able to confirm whether or not the Firmata.tox (from the palette) will work with the Circuit Playground Express board running Firmata?

https://learn.adafruit.com/circuit-play ... a/overview

Also, it appears that the Firmata main site is down, maybe has been for a while?

Any tips or pointers on how to get sensor data from this board into Touch would be appreciated. Thanks :)

I am having trouble with the firmata componant from the pallette manager. I am trying to simply switch a digital pin on and off. I have selected mode as output for the pin in the pin modes tab, and have connected to the correct serial port. I even see my little arduino blink when i toggle the serial connection. This seems to happen on multiple arduinos (tried on two micros and two megas) with different usb cords and with both the current and older versions of standard firmata.

Any ideas?

Has anyone had any luck with getting firmata->Report Digital Pins to work ? 'Report Analog Pins' is reporting the analog pin values correctly, but 'Report Digital Pins' doesn't seem to update ever. The actual firmata functionality is working fine and I'm able to set the values of my output pins no problem. When I try and monitor 'Output 2 (CHOP) Digital' the values just remain at 0.

I'm using the default firamta tox that comes in the palette menu.

An issue I'm encountering is that the serial DAT's active parameter export is not working. When I disable/enable the export from null1 to serial1, everything works again. Also switching that export to a reference fixes it as well....

I'm on Mac OSX 10.14.5 and build 2019.15840

I also discovered another issue, it may be the reason that servo's aren't totally working...

on line 271 of the firmata extension, values are multiplied by 360. Typically, the arduino servo library expects 0-180.
