![]() these commands strings changed hex display. I trying communicate microcontroller through usb serial connection using labview's visa write commands. if change pin modes, commands digital, can activate leds using labview interface, "standard firmata" sketch. ![]() ![]() I try use these same commands using labview interface, cannot activate leds relying on analog commands power. using "standard firmata" uploaded on arduino, can activate leds using digital or analog (pwm) commands through "vvvv" interface. I have progressed using "vvvv" software, seeing how pin values, pin modes encoded firmata protocol. show how convert corresponding hexadecimal values lsb, msb bits unsure how use this. The old firmata home-page offered 1 example of labview program using firmata protocol however, scanning firmata report analog pin voltage values. ![]() The desired goal uploading arduino sketch firmata functionality arduino controlled host computer using labview interface enter firmata-commands (to activate relays, run bipolar stepper motor, read values encoder, etc…).ĭoes have experience firmata protocol, how implement using visa? I use labview interface control arduino microcontroller using firmata protocol.
