2 layer PCB

Well, I may need to design a board with ESP32 bare chip (not module) on a 2 layer board. Passing FCC is mandatory. Any pioneer can tell me if it is possible, any rules-of-thumb, or I'd better starting with 4 layers? The project is just at planning stage. It is better to make sure than sorry later. T...

Re: Windows eclipse make wrapper

Hello Angus,

Windows eclipse make wrapper

Under esp-idf\tools\windows, there is a nice Windows eclipse make wrapper, which replaces building command as make $@ V=1 | sed -E "s@ /([a-z])/(.+)/@ \1:/\2/@g" | sed -E "s@-I/([a-z])/(.+)/@-I\1:/\2/@g" | sed -E "s@-L/([a-z])/(.+)/@-L\1:/\2/@g" I understand the purpose...

Re: Merry Christmas!

Just raw pixels, so 128x160x2byes= 40960bytes/frame. Should do some compression but I just wanted to push it up before Christmas.

Re: compiled windows (64?) xtensa-esp108 toolchain

Hi ladyada, I'm able to run it under Cygwin environment, Thanks! However it seems I'm not able to run it alone outside Cygwin. It gives " *** fatal error - cygheap base mismatch detected - 0x180320400/0x180321400. This problem is probably due to using incompatible versions of the cygwin DLL. Se...
