Feb 12, 2023 · Hi everyone - looking for some help to get my project off the ground. My goal is to read CAN bus and/or ODBII PID data using an Adafruit ESP32 feather and a Waveshare SN65HVD230. I will upload a pic of the wiring schematic but I feel pretty confident in that, as well as the pinout from my OBDII connector. CAN high/low both measure ~2.5V with a multimeter …

Jul 3, 2018 · Hey all, This isn't my first Arduino project, but this is the first with the waveshare SN65HVD230. Here is ...

Apr 3, 2023 · Hi folks. I am using the IDE to program an ESP32 Devkit V1 and using it to communicate with a CAN bus via the SN65HVD230 transceiver board. I was initially advised to use DIO4 and DIO5 as the CRX and CTX pins respectively. This was a project by another user on GitHub. The issue is that no CAN data is being sent, I have checked with my Pcan analyser …

Jun 21, 2013 · Hi, all: I'm trying to build a network of three nodes using CAN bus. Two nodes are built using Arduino Uno with can-bus shields from sparkfun and the third node is an embedded system running linux system. The can-bus shield uses MCP2551 with MCP2515 and the embedded system uses SN65HVD230 instead. Right now, the two Arduino boards can …

Dec 26, 2023 · Hi to all and happy holidays (or Mary Christmas) I need your help about if I can connect my arduino 3,3v (esp32 s3) + SN65HVD230 CAN Bus Transceiver Controller 3,3V with a bus system that uses 24v And this Can I connect my H L channels from SN65HVD230 module directly to H L channels of the buss line I want to read? Have I to connect the two grounds …

Apr 7, 2024 · viel wichtiger sollte die Frage sein, können die CAN Baustseine MCP2515 und SN65HVD230 so wie gedacht kombiniert werden? Bezüglich Spannungsversorgung auf der einen Seite und Spannungspegel des Busses auf der anderen Seite. Hier sind viele Kombinationen denkbar und die Frage funktioniert das so wie gedacht. Ich sage es nur vorsorglich.

Jul 28, 2023 · You can use the SN65HVD230 which is 3.3V Vcc supply rated with UNO R4 ( for Arduino Due, check CAN bus with Arduino Due - openinverter.org wiki) without a level shifter, the result will not be different for the example you refered to (below is a screenshot of UNO R4 Minima without a level shifter). That does not mean you cannot use a level ...

May 9, 2024 · We are told to setup CAN communication in aurdino R4 minima using SNV65HVD230 converter . But when we use the header file provided for can communication in aurdino i.e CAN.h from github it does'nt seem to comply with our use case . and no connection is being setup between the converters. Kindly help in order to resolve this issue.

I am using 2 SN65HVD230-based CAN transceivers on one Arduino due board which supports 2 CAN protocols but I have to make a CAN bus for 4 SN65HVD230-based CAN transceivers using 2 Arduino due boards, how to make this con…
