#27357 Hi

Was wondering if anyone has had any luck with the Digole module mentioned above. For me (on a Sparkfun Thing), SPI and UART are no-go (nothing works). I2C writes work (i.e., I can display stuff fine), but I2C reads fail (i.e., I can't use the touchscreen). Module works fine on AVR, in all bus configurations, but almost nothing works on the ESP.

I've found some examples of success with the ESP while Googling (e.g., NodeMCU--I'm using Arduino, FWIW), but all seem to be I2C and non-touch versions. I'd love to hear from anyone who got the thing working in any other setting (and what they did).

Thanks!

PS. BTW, does anyone know what this solder "fuzz" is (or what it's called) and if it's normal or not (this is my Digole board -- sorry for poor pic quality, it's iPad via loupe :) ):
