偽代碼示例

下面所示為將初始寄存器值編程到 DAC43204 的 NVM 的偽代碼序列。此處給出的值基于在設(shè)計(jì)注意事項(xiàng)中所做的設(shè)計(jì)選擇。

GPI 至 PWM 的偽代碼示例

//SYNTAX: WRITE <REGISTER NAME (Hex code)>, <MSB
                DATA>, <LSB DATA> //Power-up current output on all channels, enables
                internal reference WRITE COMMON-CONFIG(0x1F), 0x1D, 0xB6 //Configure GPI for
                Margin-High, Low function WRITE GPIO-CONFIG(0x24), 0x01, 0xF5 //Write DAC margin
                high code (repeat for all channels) WRITE DAC-0-MARGIN-HIGH(0x01), 0xBD, 0x00
                //Write DAC margin low code (repeat for all channels) WRITE DAC-0-MARGIN-LOW(0x02),
                0x43, 0x00 //Save settings to NVM WRITE COMMON-TRIGGER(0x20), 0x00, 0x02
