Hello @Steve1
I had success with the following converter settings.
This creates a array size of 8192 - same as the stock icons and displays correctly using the DrawIcon() function from the Weather app.
// array size is 8192
static const uint16_t IconCloud64x64[] = {
0x0000, 0x0000, 0x0000, 0x0000, 0x0000,
Note: I had best results converting jpg using above converter. (png did not work for me and always created an all zero array.)
Thanks
Felix
