CAN/USB management of 2 relays and some other things
|
|
===================================================
|
|
|
|
The device can also work as USB-CAN converter.
|
|
|
|
CAN protocol is quite simple. The node receives data to selected CAN ID, transmission done with the
|
|
ID = CANID + 0x100.
|
|
|
|
|
|
Pinout:
|
|
- PA0/1 - Relay0/1
|
|
- PA2..5 - Button0..3 (user buttons)
|
|
- PA6/7 - ADC inputs through resistive divider (0..5 and 0..12V)
|
|
- PA8..10 - PWM0..2 outputs (opendrain through SI2300, 5 or 12V)
|
|
- PA13/14 - SWD; the SWD pin +3.3V connected through 22Ohm resistor
|
|
- PA11. PA12 - USB DM/DP
|
|
- PB0..PB7 - CAN ID
|
|
- PB8, PB9 - CAN Rx/Tx
|
|
- PB12..15 - LED0..3 outputs (direct outputs without any protection!!!)
|
|
|
|
The pins LEDr0 and LEDr1 are indicated relay works (12V through 2.2kOhm resistor)
