    MCU with WiFi and GREAT ADCs

    Hi, I have been looking all over the Internet and the MCU that best matches what I'm looking for is the ESP32. However, those ADCs specs are not enough for my project: I'm in need of a Microcontroller that has WiFi (integrated 2.4GHz antenna) and at least 12 input ADC pins (>=12 bit...

    which microcontroller should I use for my project?

    Hi, I'm fairly new to microcontrollers and have read multiple guides, although still asking the question. I have used Arduino for quite a long time and have developed some product concept. I am only 14 years old though. I am currently developing a wearable project, therefore size, weight, and...

    Synergy GUIX Stack Size requirement

    Using the SK-S7 Synergy kit from Renesas, I was working on the ThreadX GUIX example. In the application note that Renesas provides, it tells me to increase the stack size from 1024 to 2048. Why would I need to do that? I thought it was preferable to keep the stack size as small as reasonably...

    20Khz+ PWM high-wattage LED producing too much heat

    I'm working on dimming a high-wattage LED (50W--12V/4.17amps) with a 3.3V micro-controller. The solution that has worked so far is by using a low-side (PNP) MOSFET to drive the LED and a NPN transistor to drive the MOSFET via the 3.3V signal from the MCU. At 488hz PWM I can dim the LED light...
