Segmentation Fault with Flatten() in TensorFlow Lite for Microcontrollers on STM32F746NG

I’m building a CNN model to run on an STM32F746NG Discovery board following the “TensorFlow Lite for Microcontrollers” tutorials and the TinyML book. I know that the supported TensorFlow-Keras functions […]

How to Optimize Control Pins for Basic Movement Functions in a Robot Using L298N Dual H-Bridge?

Hello.I have a simple robot with two DC motors. Using the L298N Dual H-Bridge, what’s the minimum number of control pins I can use to give me forward, back and […]

Troubleshooting Frequency Dropout Issues in Instrument with Photodetector

Hello, I am working with a instrument where we frequently get the problem of frequency drop out, i.e. suddenly frequency signal goes missing i.e. goes to zero, this cause the […]

ESP32 indexOf() function not recognizing ‘PASSWORD’ in received RS485 message

Hi everyone, I have a problem with the string function indexOf() that I don’t understand. My board with the ESP32 module is connected via RS485 (on UART1) to another board. […]

Is it feasible to run MobileNetV2 for image recognition on an ESP32 with a 320×240 camera feed?

Hello,I have a question about the feasibility of running an image recognition model on an ESP32 to recognize a single specific object, such as a person, using a camera with […]

Fixing IndexError in Gesture Recognition with TinyML on ESP32

After resolving the previous issues in my gesture recognition project on the `ESP32` with `TinyML`, I’m now encountering a new problem. The program crashes intermittently with the following error: IndexError: […]

What causes HardFault_Handler errors and inaccurate predictions in STM32 air quality monitoring Sys?

I’m developing an air quality monitoring system on an `STM32F746` using `TinyML`. The system uses a temperature, humidity, and gas sensor to predict the Air Quality Index (AQI) via a […]

Improving Gesture Recognition Consistency on ESP32 with TinyML

Hello, I’m working on a gesture recognition project using `TinyML` on an `ESP32` with an accelerometer (MPU6050). My goal is to detect specific gestures (e.g., wave, swipe) using machine learning. […]
