I need to use my trusty old school USB to RS232 cable on a Dell running WIN7 64 bit. Can anyone tell me where to find a driver for it that will run on a 64 bit? Thanks Gonzo

Chips 28X1 & 18M2 I am trying to set/clear some bits. At the moment I am setting/clearing separately e.g. Bit1 = 0 Bit2 = 0 and so on What would be easier would be to be able to do something like; Counter1 being a register B5 and above For counter1 = 3 to 11 BitCounter1 = 0 next counter1...

I am trying to invert a bit, in this case Bit4 The following code: Bit4 = Bit4 nand Bit4 Should I believe invert Bit4 as should: Bit4 = Bit4 nor Bit4 However the Programming Editor returns errors on both, but not on: Bit4 = Bit4 and Bit4 Bit4 = Bit4 or Bit4 What am I doing wrong????

Guys I am using a 28x1 @ 4 mhz. The program runs well, but i would expect it to run faster. Is there a table of average times it takes to execute commands? As an example; Do commands involving Scratchpad & Table take longer than Ram? I realise it is a "how long is a piece of string question"...

I have a USB010 cable purchased in 2005. This has not been used for 3 years. I have tried unsuccessfully to down to a 18M2. I have also tried to download to a test board that I have programmed previously. On the OPTIONS tab I can't "see" the USB/RS232 interface. Using the RS232 test I see no...

I have a project using a reading a SRF02 & 28x. It is a simple distance mearsuring program; reading the SRF02 & displaying the results. I need to look at the O/P of the SRF02. I inserted a bebug command to look at the output of the SRF02. This worked for a couple of days, then started...

Does anyone have a PICAXE Library entry for the 14M, 28X and 28X1?? Gonzo

Hi Guys, I am maninipulating 32 bits, obviously across 4 bytes. I need to run something like; Test: B0 = 0 For counter1 = 1 to 6 '7bits if bit[counter] = 0 then test2 bit[counet] = 1 Test2:next counter From my reading theis is not possible, or have I missed something? Gonzo

Hipy! I have been looking at interest at the threads on highn speed serial.... I am running a 28x Summerising what has been written; Conventional wisdom says that at a 4meg clock 2400 is the highest recommended by Reved. Correct? If you use the peek/poke method yo can run at 9600. Correct? If...

I need to build a radio link, High speed is not an issue. I was contemplating the XBee-Pro as distance & terrain are an issue at 150 metres,with some trees, but essentially LOS. A high gain aerial on one end is a possibility. Question has anyone used them? Has anyone an idea on range...

Has anyone used the Jaycar modules ZW3100 & ZW31002? What is their range outdoors?

I went thru this a while back... I need to generate a 40 khz pulse train for an ultrasonic measuring device for measuring the water in a tank. Previous advice was to use an external inverter, easy enough. That was until Mr Google found this gem...

I need to generate a 40khz pulse train for an ultrasonic device. I need in phase 7 out of phse outputs, obviously using 2 pins. I am using a 28x @ 4mhz Options include pwmout or pulsout commands. From the look of it pwmout will not be quick enough. Does anyone know how fast it will go? That...

OK Brains trust; I need to fill a bunch of memory with data, on one occasion with the same data. On another occasion with data form the serial port. I am looking for an instruction like poke (b0), temp1 ; where bo is the address into which the data in temp1 is to be stored. This is a standard...

Hi Guys. I have just purchased a PIC programmer. Can any one tell me mwhat the default settings are for the serial port, speed, stop parity, bits etc.

I intend to use a 28x in a project that require serial communications between devices. This is over a distance of 500 metres, so I am using RS422 chips on the serial i/p & o/p. Question; Do the serial i/p & o/p perform normally afet downloading the program. Or does the PICAXE overlay...
