8-Digit 7-Segment Display Driver STM32F103 · 74HC595 · SPI DMA · Timer IRQ Sep 2025 - Nov 2025 Github link: https://github.com/hieupham051100/74HC595-8-Digit-HX711

Drove an 8-digit 7-segment display through 74HC595 shift registers using SPI1.

Implemented Timer interrupt-based digit scanning with SPI DMA transfer to keep refresh stable.

Configured STM32Cube/HAL project with 72MHz clock, PA1 latch control, and CMake/ARM GCC build. ESP32 Modbus RTU Gateway to ThingsBoard ESP32 · ESP-IDF · Modbus RTU · RS485 · Ethernet · MQTT

Jan 2026 - Feb 2026

Github link: https://github.com/hieupham051100/ESP32-Modbus-RTU-Gateway-to-ThingsBoard

Built an ESP32 Modbus RTU master over RS485/MAX485, using UART2 half-duplex communication at 115200 baud.

Created a simulated 5-slave Modbus environment to test register/coil polling logic without real industrial devices.

Integrated LAN8720 Ethernet with MQTT telemetry publishing to ThingsBoard Cloud.

Used a Python-based Modbus simulator to test RS485 frame exchange, telemetry payloads, and dashboard data flow. CAN Bus Sensor Network & Logger STM32F1 · ESP32 · CAN Bus · I2C · Python Mar 2026 - Apr 2026 Github link: https://github.com/hieupham051100/CAN-Bus-Sensor-Network---STM32F1-to-ESP32

Built a two-node CAN system where STM32F1 reads BMP180/MPU6050 sensor data over I2C and transmits scaled payloads over CAN bus.

Implemented CAN frame packing with CRC-8 validation using standard IDs 0x120–0x122 for temperature, altitude, accelerometer, and gyro data.

Configured ESP32 TWAI with CAN transceiver to receive frames, verify checksum, decode payloads, and forward realtime logs over serial.

Used a Python CAN logger to visualize realtime CAN traces, pause/resume capture, and export .xlsx logs for offline analysis. Renesas RA6M5 I2C Sensor Stream RA6M5 · Embedded C · I2C · UART · HS3001 · ZMOD4510 June 2026 - June 2026 Github link: https://github.com/hieupham051100/Renesas-RA6M5-read-ICP10101-ZMOD4510

Implemented I2C0 bus recovery, timeout handling, device scan, and low-level read/write routines.

Read HS3001 temperature/humidity data, parsed raw bytes, and converted values to Celsius and humidity percent.

Output sensor readings as JSON-style UART logs for simple monitoring and debugging.
