    Thank you!

    I have prepared a page for the “project” by ARMando here: https://hackaday.io/project/168941

    From now on every update will be only on this page.
    Obviously any info can also be requested from this thread.

    Then it is programmable with wiring and c ++ ?

    If you mean by Arduino IDE sure that yes…

    Here an example of a small program with Arduino IDE that simulates a processor 8080 with Basic interpreter on ROM and relative RAM:

    Sorry, but the specs?
    Clock 48 MHz, discovered
    Flash ?? I should see the DS of the ST ?
    Ram ? idem?
    EEPROM ?
    Timers ??

    Features in a nutshell:

    64Kbytes of flash memory
    8Kbytes of SRAM with HW parity
    CRC calculation unit
    55 fast I/O ports
    5 channel DMA controller
    Calendar RTC with alarm and periodic wakeup from stop/standby
    One 12bit, 1.0µs ADC (up to 18 channels)
    7 Timers
    Features two I2C, two SPI and two USART interface

    It only has the flash, the EEPROM can be simulated in a flash page.

    However starting from the datasheet for an object like this I think is the best way…

    I have to say I saw something ST32, but I don't know how much it looks like ARMando.

    The one you “linked” is the famous “Blue Pill” which is based on an STM32F103C8T6 which is an ARM Cortex M3 at 78MHz a 48 pin.
    What I used in ARMando is an STM32F030R8T6 which is a simpler ARM Cortex M0 to 64 pin.
    If I remember correctly, the STM32F030 series is the simplest of the whole STM32 family.
    The interesting thing about the STM32F030R8T6 is that it has well 64 pin, so a high number of GPIOs, and you can find it “around” at a very low cost.
    The STM32F103C8T6 and more “powerful”, and it also has a USB interface. I used it in the past for slightly more complex cards like this or also this.

    Facendo il confronto tra quello che ho citato e l’ARMando, sarebbe come dire un Arduino Uno e un Arduino due,
    Il mio interesse potrebbe andare su uncosoche non sia obsoleto come un ATmega328 e magari sta nella misura di non dover preoccuparsi dei salti di pagina, né quante nidificazioni di routine si possono fare. Sempre per restare nella misura media di un 64 Kb di flash.
    Potrei magari propendere per il Blue Pill, che sta comodo negli esperimenti sul tagliere (breadbord per gli inglesi).
    In ogni caso complimenti per il lavoro.
