X - cmd, YZ - param.

Binary-oriented 	Param (hex)
commads:

CMD358_PING	1	xx

CMD358_WA	2	0x0001-0x7CF (1-1999)	write pwm A

CMD358_WB	3       0x0001-0x7CF (1-1999)   write pwm B

CMD358_WI	4       0x0001-0x7CF (1-1999)	write pwm I

CMD358_WO	5	0x0001-0x7CF (1-1999)	write pwm opamp

CMD358_RABI	6	xx			read pwm,dac,diag

CMD358_WDAH	7	0x0000-0xFFF (0-4095)	write dac a hex

CMD358_WDBH	8	0x0000-0xFFF (0-4095)	write dac b hex

CMD358_WCA	9	00-02 (1/4, 1/2, 3/4)	write vref comp a

CMD358_WCB	10      00-02 (1/4, 1/2, 3/4)	write vref comp b

CMD358_WCI	11	00-02 (1/4, 1/2, 3/4)	write vref comp i

(for cmd 9,10,11, when parameters other than 00-02, default 01 is used
and Ok replied)

Terminal-oriented 	Param (ascii)
commands

CMD358_PINGT 	'p'	xx

CMD358_WAT	'a'	1-99 			write pwm A 1-99%

CMD358_WBT	'b'     1-99 			write pwm B 1-99%

CMD358_WIT	'i'	1-99 			write pwm I 1-99%

CMD358_WOT	'o'	1-99 			write pwm opamp 1-99%

CMD358_RABIT	'r'	xx			read pwm,diag

CMD358_SAVE	's'	xx			save to flash

CMD358_DEFAULTS	'd'	xx			load defaults (flash preserved)

xx - any parameters (must present) (use 00 or other)

diag bits: 	01 - defaults loaded (manually or when no saved data)

		02 - modified values (when commands was)

		04 - flash error (erase or program) after "save" command

reply: Ok or Bad on cmd 1,2,3,4,5,7,8,'p','a','b','i','o','s'

(Ok replied if parameter is in range,

Bad replied if parameter is out of range)

reply: Ok on cmd 9,10,11,'d'

reply: 112233445 on 'r' cmd, 

where 11,22,33,44 - percentage of A,B,I,opamp pwm, 5 - diag byte

reply: 11112222333344445555666677 in hex on 6 cmd,

where 1111,2222,3333,4444 - value of A,B,I,opamp pwm,

5555,6666 - DAC A,B values, 77 - diag byte


Example:

Qpc358r00#	read in ascii

Qpc358a55#	write 55% pwm to A

Qpc358d00#	load defaults 

Qpc358s00#	save to flash

To save defaults to flash, use 'd' and then 's' command.

Binary oriented: 51 70 63 33 35 38 means Qpc358 in hex, 23 means # in hex

51 70 63 33 35 38 06 00 00 23	- read (cmd= 06)

51 70 63 33 35 38 09 02 00 23	- write vref3/4 to comp i (cmd= 09, param= 0002)

51 70 63 33 35 38 07 66 06 23	- write 0666 to DAC A (cmd= 07, param= 0666)

51 70 63 33 35 38 64 00 00 23	- load defaults (cmd= 64 'd')

51 70 63 33 35 38 73 00 00 23	- save to flash (cmd= 73 's')
