[ Infineon PSOC 62S4 PIONEER KIT Review]——DAC

• Basic Introduction

According to the manual, the PSOC 62S4 PIONEER KIT has a 12-bit DAC with a settling time of less than 2μs, which can be driven by the DMA controller to generate user-defined waveforms. The DAC output can be a resistor ladder output (approximately linear) or a buffered output using the operational amplifier in the CTBm block.

2. Introduction to main APIs

1.DAC initialization cyhal_dac_init()

2.DAC sets the reference voltage cyhal_dac_set_reference()

3.DAC output cyhal_dac_write()

PS:

1. I looked through the data sheet but couldn't find which pins can be set as DAC output pins.

Yes, it was acquired by Infineon Technologies...

Are these okay? P10[0] - P10[7], P11[0] - P11[7], P12[0] - P12[7], P13[0] - P13[7]

Initialization of P10_0, P10_1, P10_2, P10_3 failed

P10_4, P10_5, and P10_6 are connected to the temperature sensor on the development board, which is inconvenient to use

P10_7 is connected to the ambient light sensor on the development board, which is inconvenient to use

The remaining pins are not brought out on the development board

Can a 12-bit DAC be used as a reference power supply?

It depends on your actual needs

Here are some characteristics of the DAC from the data sheet:
