ATM90E26 FeatherWing (Huzzah) crashing

[MrPivato]

Hi! I am using an ATM90E26 Featherwing v1.5, with an Adafruit Huzzah.
The problem comes when I try the example skecth ATM90E26_Full_App.ino, I only updated it to run newer versions of ArduinoJson and WifiManager, as you can you can see here: My Fork.

When it tries to check the checksum, the result is a crash, but connection to WiFi and Thingspeak is ok.
Here is the error message

{"auth":"XXXXXXXXXXX","server":"api.thingspeak.com"}connected...yeey :)
Key:XXXXXXXXXXXX
Server:api.thingspeak.com

Checksum 2:FFFF

If anyone could help me solve this problem I would be grateful, thanks in advance!

In firmware interaction of the various parts is crucial. I haven't checked the code in your fork, but do you have the SPI/ UART jumpers set correctly ? Can your monitor transactions on the serial bus using a logic analyser ? Some images of your stack up and jumper settings will help with this issue. Looks like no values are being read from the ASIC hence the FFFF.

I am using the stacked version. Here is the image:

Hello @whatnick
Any tips?

[whatnick]

Could I please see the jumper settings underneath.

[MrPivato]

You mean here?

[whatnick]

Please set jumpers for SPI or UART mode as appropriate. No jumpers have been set. Here please check the PCB or code repo for the jumper options.
