ESP32 Programming - Classical CAN to Bluetooth Gateway
In this post, I will present a CAN to Bluetooth gateway based on the ESP32 processor. The above image shows my test setup using our ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module, a CAN-Bus Hub With 7 Ports And DC Power Connection, and the PCAN-USB Pro. As its description implies, the ESP32 module provides all necessary [...]
PCI Express Board Integrates 4 High-Speed CAN/CAN FD Ports
Kvaser has introduced their compact M.2 PCIe, a highly integrated embedded CAN Bus board that adds four high-speed CAN/CAN FD channels to any host computer with PCI Express connectivity and an available B or M keyed M.2 slot. The embedded board provides four distributed CAN CC (Classic CAN) or CAN FD transceivers, adding CAN CC and CAN [...]
Elevate CAN Bus Troubleshooting Skills - Online Training
It is in the nature of our business that we at Copperhill Technologies frequently receive requests for support. The most common problem is that beginners of the technologies run into problems getting their CAN Bus network going. There are a few steps that can be done to solve nearly 99% of the problems, and they [...]
ESP32: CAN Bus Programming with MCP2515 and MCP2517FD
For good reasons, the ESP32 processor is a prevalent choice for embedded hardware development. Besides considerable memory resources, it provides various hardware features for many applications, most prominently the Internet of Things (IoT). All that comes with more than reasonable price tags, specifically when you use one of the multiple ESP32 development modules. And since [...]
Linux Development Board, Integrates ARM Cortex-A7 Processors
The LuckFox Pico represents a cost-effective Linux micro development board based on the Rockship RV1103 chip, which supplies a straightforward and efficient development platform for embedded system designers. It supports a variety of interfaces, including MIPI CSI, GPIO, UART, SPI, I2C, USB, and more. Developing applications is convenient, and debugging is quick.Features The single-core ARM Cortex-A7 [...]
Discover IoT Development with ESP32 to Create Smart Devices
The ESP32 is a low-cost, low-power SoC (System on Chip) microcontroller with integrated WiFi and dual-mode Bluetooth. It has shipped over 100 million units as of 2018 and powers many WiFi devices on the market. This book supplies end-to-end coverage of building an IoT system from the ground up to secure data communication techniques from [...]
ESP32: Isolated CAN Bus Repeater and Baud Rate Converter
With this application, I am adding yet another example to the vast CAN library we developed over the years. The use of the Dual Isolated CAN Bus HAT with the ESP32 opens the door to a number of possible applications. The development of a CAN repeater and/or Baud Rate Converter came to mind first, because the [...]
ESP32 UART0, UART1, UART2 Access Using the Arduino IDE
In the following, I am using the ESP32 WROOM Devkit for this tutorial in combination with the Arduino IDE. For more information on programming the ESP32 using the Arduino IDE, please refer to “Getting started with ESP32 development board and Arduino.” The Arduino IDE uses the Serial class (assigned to UART0) to access the USB port [...]
Do NOT Install ESP32 by Espressif Systems Version 3.0-alpha1
Today, I experienced a little scare. As usual, I opened the Arduino IDE on my Windows-11 machine, and as a first action, I allowed the recommended updates. Not suspecting any significant problems, I added some code and compiled it, only to end up with multiple error messages. I found nothing wrong with the code I had [...]
Kvaser's Leaf Supports Classical CAN, CAN FD in Silent Mode
Every professional CAN Bus development, may it be Classical CAN, CAN FD, or higher layer protocols such as SAE J1939, requires a data monitoring device for proof of functionality. Kvaser has introduced such a device, the Leaf v3 interface supporting Classical CAN and CAN FD in optional Silent Mode. The Leaf series depicts one of the straightforward [...]
