pv450+ESF INPUT

pfu · Post by **pfu** » Mon Nov 28, 2011 1:47 am

I got a application that PV450 will input fuel level by ESF . You know the ESF that 240ohms means empty and 33 ohms means full. I have got a case from forum, and flash into PV450 for test, but i find the data is not correct. when 33ohms, i got 78 raw analog input and 0% fuel level; when 240ohms, i got 384 raw analog input and 82% fuel level .It seems they are reverse. so who can help me ? the attachment programming is correct?

Hello pfu,

When did you download that configuration?

That configuration has an incorrect conversion table but it should have been replaced with the correct conversion table.

You can correct the table in the script manually or download the new configuration.

Code: Select all

// Fuel sender table
uint[][] es2f = {
	{  66,100}, // tolerance
	{  81,100},
	{ 110, 90},
	{ 136, 80},
	{ 162, 70},
	{ 186, 60},
	{ 211, 50},
	{ 243, 40},
	{ 271, 30},
	{ 308, 20},
	{ 348, 10},
	{ 385,  0},
	{ 403,  0}, // tolerance
}; // raw, percent
