  1. ENC28j60 fail

    RogerClark

    There is a clock multplier on the clock frequency inside the STM32. ( It is set to 9 times multiplication, hence 72mhz which is the normal clock freq for this device)
  2. ESP32 in Pre-Order

  3. ESP8266 as an access point!

    RogerClark

    … same thing using the Arduino IDE. Programming for the ESP8266 is not the same as the STM32 or ATMega devices, as your code just get called by the OS in response to events. I think the loop() function on ESP8266 is actually called on a timer interrupt, so does…

    …a post that such processes are anti-Arduino, conceptually. For someone coming over to STM32duino from AVR, it is paradigm quicksand because not only are we STM32_centric, we may even be writing code to a specific uC within the STM32 product family. This is a g…

    Which one from stm32duino? If I search https://github.com/rogerclarkmelbourne/Arduino_STM32, I do not find anything related to Firmata. Yes this one, I think. As it mentions “including LeafLabs Maple, and Maple mini”. For the library, I don’t know it, I provid…

    [RogerClark – Wed Jul 05, 2017 4:45 am] – Actually, It looks like I need to manually merge if Serial because it removes isConnected, which some people may already be using in their sketches I think I need to keep isConnected by perhaps mark it as deprecated Ro…

    stevestrong

    Do not power the board form STlink, it does not give enough power. Do not connect the power wire from the STlink at all. Just use a separate cable from PC (or 5V adapter) to the mini USB socket. For the generic black F4 board (or mini variant) you may try my r…
