Have you turned the Auxiliary DAC on ? It has its own power control bit and bit 5 (ADACS) in TOGBR1 hat to be set to turn the Auxiliary DAC on. I just did a quick test with a C123, and the following seems to work: twl3025_reg_write(TOGBR1, 1 << 5); // turn ADAC on twl3025_reg_write(AUXDAC, 1000); delay_ms(1500); twl3025_reg_write(AUXDAC, 0); twl3025_reg_write(TOGBR1, 1 << 4); // turn ADAC off Best regards, Dieter -- Dieter Spaar, Germany spaar at mirider.augusta.de
