Hello gang again, I have a quick question for the experts here. I have a progam loop that is intended to run in a tight loop, checking 6 different flow pulses (the pulses come in at 330 per liter of water pumped) I am trying to determine if the program loop is 'quick' enough to catch the one...

Hi gang, for my water project, I am looking at a variation of my design to date. I have decided to use the opensprinkler program, running on it's own RaspPi or equivilent 'arm' board, which gives me conveniant web access to the sprinkler system, and it's about the same price as me putting all...

So for my ongoing remote I2C project using P82B715 bus extenders, I am experimaneting with speeding up the main program running on a 40x2 from 8mhz to the full 64mhz (using i2c slow, 100kbps). I am running an i2c eeprom, clock, a matrix orbital 4x40 display set up for i2c, and the 715 extender...

Looking for some help on using 40 meters of Cat5 twisted pair with I2c (slow), with 3 nodes. I have both the P82B715 extenders, as well as the alternate P82B96 units as well. What will be hooked up I2C wise: Node1: 40x2, clock, eeprom, lcd, P82B715 (total capacitance = 50pf) 10 meters away...

I am continuing may household water contoller program using 2-40x2's, 1-20m2, and a long distance I2c 'cord'. Pretty well coded up all 4 program slots on the main 40x2, hoping I can cram in an irrigation controller in the main 40x2 before I completely run out of 'memory'. The main 40x2 has...

I am trying to configure an axe133 using the winstar 4x20 OLED to communicate as fast as possible with my main 40x2 which is going to run at 64mhz. I am hearing through other posts that the max speed is 4800 baud. If that is the case I need to slow down the main pic down to 32mhz as that is...

Just a quick question, I am building a picaxe project that will be ADC reading a series of 4-20ma sensors running off 24 volts. I want to put in an overvoltage protection circuit so I don't 'blow' any more of my picaxes (lol). I can't drop voltages with a resistance divider like most input...

Hi fellow campers, I am having some difficulty getting two 28x2's (5 volt) to chat with each other using I2C. Picaxe #1 is going to be set up to monitor water flow pulses (5 of them) and record to the scratchpad the cumulative flows (in liters, about 330 pulses per liter), as well as...

I know, this is a picaxe forum, not a Pi forum. However, I'm trying to set a a communication setup between a raspberry Pi running a webserver, through a wiznet 110Sr ethernet to serial converter board to my 40x2 running a water monitoring program. So there is a picaxe in the mix there...

Hi gang! I am a beginner experimenter with the picaxe system. I am doing some conceptual design to build a controller/monitor, preferably using either picaxes, or possibly also using a data acquisition device I bought a while back (DLP deisgns I/O20 usb data acquisition module) for a small...

Hi gang, I am in the process of building a water treatment system for my domestic well (actually, 2 wells). I have a salinity problem in at least one well, and I expect to have to use a reverse osmosis unit to remove the salinity (200-1000 ppm). I expect the salinity levels to vary during the...

I'm using a 40x2 in the programing Editor. Sometimes I notice that data will not populate in the debug window - even with substantial pauses placed in the program code. Is there a way to coax the data out into the debug window?? The pins window seems to work fine, just sometimes I have all...

HI folks - I need a hand on a problem I'm having. I'm trying to drive a series of 8 single coil 12V latching relays from a 40x2. As I'm somewhat short on digital outs, I stuck a MCP23017 I2c digital output in there to allow the picaxe to separatley control all 16 (2x8) coil leads through...

I have a quick question for the group. I have been putting together a picaxe project (40x2) to maintain 4 - 220AH 12V Lead Acid Battery banks for our cabin, which are powered by solar and generator. The design will include periodic battery discharge testing, individual bank...
