Hi,

Did anybody try to connect the CJMCU-8128 with a wemos d1 mini pro?

I've uploaded the code from this project to the device and that sort of works but in the serial monitor I get some stange readings and I have to set the serial monitor to 115200, when set to 9600, it shows a lot of jiberish. The only thing it shows in delays is:

load 0x4010f000, len 1392, room 16 tail 0 chksum 0xd0 csum 0xd0 v3d128e5c ~ld v⸮⸮⸮

btw, when set to 9600 it shows: ⸮!⸮L⸮<1⸮1⸮⸮⸮

No real measurements as output and stated in the code.

Anybody any idea? Any help would be appriciated!

Kind regards

Richard

Hello Richard, with some delay I found your issue. You are right the reduction of the serial monitor is useless and confuse. So I commented out the line. For your purpose I suggest that you change the PIN to the corresponding I2 C Wemos I think it's D1 and D2 but I'm not sure. - It's on the line Wire.Begin(D1,D2) instead of wire.begin(21,22)

Hope you can follow and close the issue. Regards stefan
