Re: ESP32 Elliptic curve cryptography with micro-ecc, aes, sha example

Hi pcbreflux,

this is really cool.
Please, more of those examples.

Something like reading from an uart (e.g. rfid rdm6300 keys) and sending it as encrypted mqtt messages via wifi to a mosqitto server. ;)

Keep on publishing.

Best regards.

[solved]: freertos: c-example blink and cpp-example blink - invalid conversion error in cpp

Hi there, out of curiosity I just wanted to compare the usage of freertos within a blink example between 'c' and 'cpp'. So here are the examples. The c example works fine. The cpp example gives me some errors like this at gpio_set_direction(BLINK_GPIO_1, GPIO_MODE_OUTPUT); error: invalid conversion ...

Re: interface motor pwm - already supported and provided example?

Hi there, thanks for the hints. Actually, I saw Neil's video about ledc pwm which is quite informative (as well as Neil's book is). I read through the esp8266 reference manual as well for a motor pwm library. Is there a special reason why this interface is not provided yet? For me and many other pot...

Re: [Solved] Eclipse, C++ and the Standard Template Library

Howdy Neil, yeah, for lambda I took an additional dive here: http://en.cppreference.com/w/cpp/language/lambda By the way, you mentioned that the Xtensa toolsuite supports C++11. Is it likely that it will support c++17 in the near future? The reason why I ask is because I am interested in the feature...
