Espressif SDK 1.2.0

smileyJust today a new release of the SDK from Espressif along with a patch.   I note they have brought back the watchdog controls. Tried it on our code and up to now it’s absolutely fine. Still no sign of the PWM_STOP() function I’m waiting for however.

There is a one-liner remark about memory optimisation. I can’t swear to it but I’m fairly sure I noted a marked drop in the amount of RAM used… the limiting factor for me for a while has been .text space and that was as high as 0x7c00 at one point – a bit of a worry as it only goes up to 0x8000. However between finally getting different types of array into FLASH and the updates I’m now down to 0x744e which is a lot more healthy! See the Espressif forum (downloads) for a complete list of changes. http://bbs.espressif.com/viewtopic.php?f=5&t=680
