hi,

if you had the same “problem” that i have. find the section below in opensprinkler.cpp
you have to add ~ in the pca9555 section so it will look like this reg = (reg&0xFF00) | ~station_bits[0]; // output channels are the low 8-bit

// Handle driver board (on main controller)
if(drio->type==IOEXP_TYPE_8574) {
/* revision 0 uses PCF8574 with active low logic, so all bits must be flipped */
drio->i2c_write(NXP_OUTPUT_REG, ~station_bits[0]);
} else if(drio->type==IOEXP_TYPE_9555) {
/* revision 1 uses PCA9555 with active high logic */
uint16_t reg = drio->i2c_read(NXP_OUTPUT_REG); // read current output reg value
reg = (reg&0xFF00) | station_bits[0]; // output channels are the low 8-bit
drio->i2c_write(NXP_OUTPUT_REG, reg); // write value to register

great. thanks it work perfectly

i think that i found the answer. it is in the branch ether4os32?

[rastafd]

i was afraid that was the answer :-).

i had a lot of trouble compiling the code whit Arduino ide on windows . son i took my linux computer and was able to add the tiny character “~” to reverse the trigger. and thanks for pointing me to the right file.

everything now is working.
the repository on github is not the 2.1.8 (6) only 2.1.8 (4) is that correct?

hi,

not exactly,

to activate the 8 stations whit my previous setup, pcf8574, the pcf8574 send low “0V” to active the relay board.

and now the pca9555, it send high “5V” to activate my 8 channel relay.

so previously, pcf8574, wen a activate a station the relay activated and now 9ca9555 the relay is always activated except wen a start a station.

does that make scene?

received the pca9555 and rewired everything. all seems fine except the trigger from the pca9555 seems to have change to high and before it was low.

is this normal? or i am missing something.

is there a easy fix.

thanks

The ecn26j60 will only work if i disconnect the 2 pfc8574, But i don’t have any relays working

For now the enc28j60 is not working . There is a pcf8574 x20 under the nodemcu for the button. The relays are connected to the red pcf8574 x22 that you can see. The way i understand it is when i receive the pca9555 and address it to x22 and remove the 2 pcf8574 the system will detect version 3.2 and the enc28j60 will work and the relays.

Thanks for the reply i will ordre some pca9555. Here a picture of my oppensprinkler. You did a great job.
The only thing missing is one siol moisture for each zone . That way it will be use for multiple plant watring

hi,

i have build a 3.0 version and wired a enc28j60 to it but it dose not work. i have to disconnect the pcf8574 then is work. how come?
its seems to work only if it detect a 3.2 version. but i don’t have a Pca9555 on hand only pcf8574 and pcf8575.

thanks
