also coming from linux + some bare-metal experience, esp-idf was absolutely horrifying.

fortunately it turned out that the s3 hardware (i've got a cardputer) isn't that crazy, and it is relatively easy, if almost completely untrodden, to program much of it from scratch (which is the familiar way to do embedded for me).

my iteration loop is ~30ms for a small program (i download directly to ram so as not to degrade flash).

people are now actively working on reverse engineering wifi, which so far has been the major reason to use espressif's software stack (their driver runs under freertos).
