The interface that saw the light of day around the mid-1990s was a joint effort of seven companies – Compaq, DEC, IBM, Intel, Microsoft, Nortel, and NEC.

Status information is shown on the OLED and used to control the PS4 LED and rumble function for a direct feedback to the "driver". Vise versa D1 R32 sends a messages with ID 0x20 containing a status of the front assistant system (autonomious breaking based on distance in front collected by the TOF sensor), status of tilt warning system (pitch and/or roll > 45° gathered by IMU). In the project IDs 0x10, 0x11 and 0x12 are used to transfer the information from the PS4 controller connected to D-duino32 over CAN to D1 R32 which calculates the steering/throttle and finally the left and right motor speed from it. So already by creating a message catalog some care is needed also for the order of IDs and not only payload. This ID is also equivilant with a priority (smaller ID has higher priority in case of concurrent abritration). The messages (or frames) are differentiated by network-wide unqiue IDs. If you are interrested how the bus abritration per ECU is handled and how the complete frame formate looks like, please have a look here. Here I used the standard format which uses up to 8 bytes per message as payload. The comminication over CAN between the ECUs happens by frames.

I guess the voltage regulator of the D1 R32 is just not capable enough to drive the shield, sensors plus the D-duino32. After applying battery power by the help of the regulator directly to the D-duni32, the problems were gone. I tried it by using V5 & GND from D1 R32, but struggled a lot with strange behaviours (especially about the CAN communication). The battery box and motors are connected to the shield and finally the D-duino32 is power by the help of a DC regulator (AMS1117-5.0V). Motor shield, TOF/IMU sensor are connected to the D1 R32 by I2C (SDA & SCL).

Afterwards both are connected to each other via CANH and CANL (no cross-over). They are going to be connected from their CRX and CTX to GPIOs of the MCUs (no cross-over). The used SN65HVD230 transceivers need to be powered by 3.3V and are using the same as signal level. The ESP32 has got an integrated HS CAN controller, so we just need to hook up a matching CAN transceiver on both MCUs, compare here. Here the major focus is the high-speed (HS) CAN connection - whereby "high-speed" tells us more about the electrical behaviour rather than the baudrate. So let's have a look what came out of the spare time activity.īut what is now about the CAN communication? Before we have a closer look at it, I would like give an overview about the wiring used for this build. After a small while everything was assembled. I picked up a tracked chassis with 2 motors from DOIT (T101 mini), a Wemos D1 R32, a D-duino32 with on-board OLED, a motor shield from Adafruit, a TOF sensor (VL53L0X) for distance measurements, an IMU (MPU9250) for tilt detection, a battery box, some screws & nuts, jump wires and last but not least two CAN transceivers (SN65HVD230).

An Arduino based crawler/tank!? Haven't we already seen dozens of them? Maybe, but not such a variant.
