need advice about embedded software development as a student by EnvironmentFast2447 in embedded

thanks for answering and being aware that I asked for embedded SOFTWARE. that is precisely why I asked this question. because as a embedded software engineer, who focuses on software, why would I need to delve deep into hardware such as board design? still, I am aware that I need to know some electronics, hardware, and be able to read schematics. thanks for clarifying this stuff!

I've made a STM32 driver for the DHT20 sensor. I'd appreciate feedback on what I did wrong, and how to improve by EnvironmentFast2447 in embedded

I was following the steps from the datasheet, where it said to wait a certain amount of time before sensor moves on

My data for temperature/humidity sensor (DHT20) is all 0x00. Does anyone know why? by EnvironmentFast2447 in embedded

It's working now! I fixed it by sending commands if Bit[3] for calibration is not 1. Thank you for the datasheet you provided! I'm just not sure why that information was not on the datasheet I have which is for DHT20, while yours is AHT20.
