🚀 Quick Start

Running Tests

Navigate to ESP32 examples directory:

cd examples/esp32

Build and run specific test:

# Build CAN test
idf.py -DAPP_NAME=can_test build flash monitor
   
# Build GPIO test
idf.py -DAPP_NAME=gpio_test build flash monitor

Run all tests:

# Build all test applications
./scripts/build_all_tests.sh

Test Configuration

Each test can be configured by modifying the respective test file:

Test sections: Enable/disable specific test categories
Hardware pins: Configure GPIO pins for testing
Performance parameters: Adjust timing and throughput settings
Error thresholds: Set acceptable error rates

Hardware Requirements

Most tests require minimal hardware:

ESP32-C6 DevKit - Primary development board
Jumper wires - For connections
Basic components - Resistors, LEDs, sensors (test-specific)

Special Requirements:

CAN Test: SN65HVD230/232 transceiver, 120Ω termination
SPI Test: SPI device or loopback connections
I2C Test: I2C device or pull-up resistors
Display Tests: Compatible display hardware
