Please be sure to answer the question. PURPOSE: Construction of digital-to-analogue converters using different techniques, namely the scaled resistors into summing junction, and the R-2R ladder. The STM32 DAC system is described in Section 1 of this document, while an application example focusing on 5 Msps sine wave generation is presented in Section 2. This IC comes in A 12-bit R-2R ladder digital-to-analog converter (DAC) circuit is used as an example through the critical stages of the education process, starting with theory and calculations, then moving on to circuit simulation and prototyping. 1° – Consult the manual of the STM32 that you want to use. The code is very straightforward and I've endlessly studied the datasheet, Google, various examples and tutorials. That looks like a terrific resource if you want to learn how to use the bare-metal Rust libraries from someone who actually knows what they’re talking about. Monolithic R-2R resistor networks are available from various resistor component manufacturers, making it easy to incorporate them into your designs. DACch1 out is PA4, DACch2 out is PA5. For example, if your TOP value is set to 255, the output will go high at 0, and then low again at some number between 0 and 255, so you get 256 possible positions, or 8 bit resolution (2^8 = 256). If anyone else is interested, it seems like the only suitable DMA channel that can drive DAC_1 is DMA2 channel 3. R-2R DAC Example (cont. As it can been seen, programming the DAC block is very straight forward. The DAC + may be configured in 8 or 12-bit mode. Applicable products. This is a 12 bit DAC converter.
