Hey Guys and thanks for your help. I'm a student at University of Trier (Germany) and i want to transfer this working Arduino IDE C-Code to Altair Embed.

#include <Wire.h> #include <Adafruit_MCP4725.h>  Adafruit_MCP4725 dac,dac1;                            void setup(void) {          Serial.begin(9600);              dac.begin(0x60);       dac1.begin(0x61); }  void loop(void) {             uint16_t i=200;              dac.setVoltage(i, false);       dac1.setVoltage(i, false); }

The i variable(see above arduino ide) should be replaced with slider properties in Altair Embed for real-time
changes(does Target Interface Block work for this?)).
The problem is also that the method "setVoltage"(Arduino IDE) needs an uint16_t datatype.
The "convert to" block in embed has no uint16_t type.

My embed vsm does not work see attachments. I'm thankful for ideas.
