A usefull thing made of chineese FX3U clone
|
||||
===========================================
|
||||
|
||||
Works over RS-232 (default: 115200, 8N1) or CAN (default 250000 baud).
|
||||
|
||||
You can see pinout table in file `hardware.c`.
|
||||
|
||||
## Serial protocol (each string ends with '\n').
|
||||
|
||||
```
|
||||
commands format: parameter[number][=setter]
|
||||
parameter [CAN idx] - help
|
||||
--------------------------
|
||||
|
||||
CAN bus commands:
|
||||
canbuserr - print all CAN bus errors (a lot of if not connected)
|
||||
cansniff - switch CAN sniffer mode
|
||||
|
||||
Configuration:
|
||||
bounce [14] - set/get anti-bounce timeout (ms, max: 1000)
|
||||
canid [6] - set both (in/out) CAN ID / get in CAN ID
|
||||
canidin [7] - get/set input CAN ID
|
||||
canidout [8] - get/set output CAN ID
|
||||
canspeed [5] - get/set CAN speed (bps)
|
||||
dumpconf - dump current configuration
|
||||
eraseflash [10] - erase all flash storage
|
||||
saveconf [9] - save configuration
|
||||
usartspeed [15] - get/set USART1 speed
|
||||
|
||||
IN/OUT:
|
||||
adc [4] - get raw ADC values for given channel
|
||||
esw [12] - anti-bounce read inputs
|
||||
eswnow [13] - read current inputs' state
|
||||
led [16] - work with onboard LED
|
||||
relay [11] - get/set relay state (0 - off, 1 - on)
|
||||
|
||||
Other commands:
|
||||
mcutemp [3] - get MCU temperature (*10degrC)
|
||||
reset [1] - reset MCU
|
||||
s - send CAN message: ID 0..8 data bytes
|
||||
time [2] - get/set time (1ms, 32bit)
|
||||
wdtest - test watchdog
|
||||
error=badcmd
|
||||
```
|
||||
|
||||
Value in square brackets is CAN bus command code.
|
||||
|
||||
## CAN bus protocol
|
||||
|
||||
All data in little-endian format!
|
||||
|
||||
BIT - MEANING
|
||||
|
||||
0, 1 - (uint16_t) - command code (value in square brackets upper);
|
||||
|
||||
2 - (uint8_t) - parameter number (e.g. ADC channel or X/Y channel number), 0..127 [ORed with 0x80 for setter];
|
||||
|
||||
3 - (uint8_t) - error code (only when device answers for requests);
|
||||
|
||||
4..7 - (int32_t) - data.
|
||||
|
||||
### CAN bus error codes
|
||||
|
||||
0 - `ERR_OK` - all OK,
|
||||
|
||||
1 - `ERR_BADPAR` - parameter is wrong,
|
||||
|
||||
2 - `ERR_BADVAL` - value is wrong (e.g. out of range),
|
||||
|
||||
3 - `ERR_WRONGLEN` - wrong message length (for setter or for obligatory parameter number),
|
||||
|
||||
4 - `ERR_BADCMD` - unknown command code,
|
||||
|
||||
5 - `ERR_CANTRUN` - can't run given command due to bad parameters or other reason.
