    También funciona con los móviles Android

    Hardware real, configurado en la FPGA con sólo apretar un botón... así de fácil 🙂

    Y por supuesto, sólo utilizando herramientas libres

    Esta es la interfaz en la web
    Ahora se pueden hacer demos muy sencillas para el usuario: carga de programas de pruebas de la placa, carga de diferentes "ordenadores retros" (zx-spectrum, amstrad...) con sólo apretar un botón. ¡Imaginación al poder!

    Ejemplo de webapp para descargar circuitos con sólo un botón. Al pulsar Blinky7 se carga el circuito que hace parpadear el LED7, y con Blinky0 el LED0. Sólo hay que pulsar un botón y ya tenemos el circuito cargado!

    ...y ¡Ya se pueden carga bitstreams en la FPGA desde el móvil Android a través de la aplicación web!!!! ¡Qué gran hito!

    Esta no es la webapp final, sino una prueba de desarrollo. Inicialmente hay un bitstream que endiende el LED D0. Se carga otro que enciende el LED D7. El proceso tarda unos segundos

    Esta es la nueva Interfaz gráfica para hacer las pruebas

    Ya está implementada la grabación de bytes en la Flash! Estoy a un paso de grabar bitstreams directamente desde el móvil!

    Más pruebas con la WebApp para acceder a la flash de la FPGA en la #AlhambraII. Ya consigo borrar un sector de la flash, que es el paso previo para poder grabar datos y/o bitstreams!

    El acceso al FTDI lo estoy implementando a pelo en javascript, usando Webusb

    Pruebas de acceso a la flash de la Alhambra-II desde el móvil, usando una aplicación web. De momento se puede resetear la FPGA, leer el identificador del chip de la flash, y hacer lecturas de bytes de cualquier dirección

    Esta es la webapp de pruebas:
    obijuan.github.io/Web-iceprog/

    Es necesario usar un navegador que soporte webusb como por ejemplo Chrome

    mmm... FDTI driver issues it seems, but I know I installed the ftdi package? Can't find iCE FTDI USB device. Maybe permissions?

    Yep! Needed to add my user to the     tty group (like dialout group on ubuntu) for /dev/ttyUSB* on Void Linux.

    Step 1 is Software to talk to this thing I guess. Gotta get the Yosys, NextPNR & IceStorm tools installed it seems. ✅ #FPGA #openSource #alhambraII #ice40
