    Re: Ethernet with microcontrollers

    + that statement.

    Using one of the wifi modules amgen hints at is by far the easiest way to extend TCP/UDP support to a microcontroller.

    Considering the popularity of the modules, they are...

    Re: Parsing strings received serially.

    Indeed it does; somehow did not stumble across the 2nd thread; Heckler's response looks pretty much what I needed.

    Thanks for the pointer.

    Hi guys,

    I Havent used PBP for quite a while, and I'm afraid my memory is getting rusty.

    I need some help with string parsing.

    I get a stream of data over the serial port in the format...

  5. Re: SEROUT,HSEROUT or DEBUG ? max 232 or no max232 ?

    Hi,

    Can I assume your wifi device is a variation of the ESP8266? If so, you would NOT require a MAX chip between the PIC and the Wifi module. Serout, Hserout should work, as also debug (the last...

    Re: Been away from PIC a long time

    Michael, to add to what Henrik said; the EPIC is a parallel port driven programmer; are you sure you still have a parallel port on your PC?!

    Your best bet would be to go in for a Pickit2 or...

    Re: Sharing my enthusiasm too!

    Right, that makes sense.

    If your project requires an ESP as well as Bluetooth, you might want to hold on the final design and migrate it to the expected-soon ESP32, which supports Wifi as well as...

    Hi Heckler,

    I have a couple of ESP01s, ESP01s with flash upgraded to 4mb, ESP07s and a nodeMCU board in my arsenal.

    Re: Sharing my enthusiasm too!

    Dave, I should have been more explicit in describing option 4; I just use the Arduino IDE, and directly program the code into an ESP8266, there's no physical Arduino involved.

    Re: Hex values to decimal

    Of course you can do the conversions in Excel; but again, how would you get the data into Excel in the first place? And if you do that, (using something like StampDaq or some such), then why not let...

    Re: Hex values to decimal

    Output the data serially on the UART or bit bang it out of a pin?

    Why involve a pickit3 at all, for just reading the stored data?

    Re: RS232 with multiple slaves

    At 2400 baud, and one-way comms, I would even try without the RS-485/422 driver, simply modulating the signal with a transistor (or a pair, to retain the polarity) at the transmitter end, at perhaps...

    Hi,

    Here's what had worked for me. Richard is right, you cant use HPWM for frequencies above 32.768khz.

    Set the registers as follows.

    TRISC.2 = 0 ' CCP1 (PortC.2 = Output)
