    Midas vs Winstar 16x2 OLED

    I'm considering getting another 16x2 OLED display. So I download the specs of the Midas units. They appear to have some nice functions compared to Winstar. Like... smooth horizontal scrolling and line shift selection. Have any of you guys used one of these? To confirm that they will do these...

    RTC with 2/3 day lenght time

    Thanks Ibenson (y) I think I learnt more about Picaxe with this build over the last month, than I had in the last 10 years. Most of my past builds used Picaxe's like a PLC. I just have a bit more time on my hands at the moment.

    RTC with 2/3 day lenght time

    This is the first half a project that I started working on a month ago. Although it still works as a free standing unit at this point. The other part will be external with sensors. Plus I wanted to say a thanks to all you guys that have help me along the way, with many posts and snippets that I...

    Bptr Symbol and S_W variable questions

    Thanks for input and thought into the matter guys. I'll give your layout a go Aries, and see how I find the application of it. The reason for asking the original question was to find a simple and tidy method of doing this. Without too much memory use. As you can imagine, if I have already used...

    Bptr Symbol and S_W variable questions

    Thanks Ibenson. I was hoping there may have been some tricks that others had came across in there use of these two functions. Its useful to have extra variables. But I find myself getting lost with the use of too many BPTR. It would make reading the code far easier if they could be assigned to...

    Bptr Symbol and S_W variable questions

    I'm wondering if there is a way to give a Bit Pointer locations a Symbol? The example below doesn't check out. But I was wondering if there is a way to do it, that I have missed. Symbol TEST = bptr = 50 Main: If @TEST = 1 then : Goto stuff Endif And also wondering if a Special Word variable...

    Using a voltage divider to measure battery voltage

    That's correct. I feed a variable bench power supply into the ADC pin. Then debugged it with a meter.

    Using a voltage divider to measure battery voltage

    I used ADC10. Here is the settings that I have tuned the ADC to. Its based on a classic Lithium Ion Voltage vs Capacity table. Driving a custom character on the display. The current drain is < 8mA. So load is not going to effect the readout at all. Its really just a general reference of the...

    Using a voltage divider to measure battery voltage

    Thought I better report back on my results. For those who might be interested. The ADC pin was directly connected through a 12K resistor to a 1S Lithium Ion 18500 cell. With a 10k tie down resistor on the ADC pin also. The Picaxe was driven off a boost regulator to take the 3.8v nominal cell, up...

    Using a voltage divider to measure battery voltage

    What happens in this case, when the ADC pin is powered by the batteries (e,g. 3.7v). If the Picaxe VCC (5v) is turned off, with a GND still connected. Will the ADC input pin be damaged, without the Picaxe having a supply voltage?

    Displaying Letters via lookup command

    I think it might be the 78M05. I forgot that I measured the 18M2 current with a switching regulator. Although the project will be running off a single 18650 cell. With a boost regulator to take it up to 5v. Could run it at lower voltage. But the little board I have is a CV CC charger, LVC/OVP...

    Displaying Letters via lookup command

    I was surprised how well the OLED "Internal Power mode" command works. #23 On/full brightness and #19 Off/dimmed. When I was just using the 18M2 on the OLED 16 x 2. It was draining 22mA @ 5v, 16Mhz. But when I went to internal power mode OFF, the current dropped to 3.7mA (with the 18M2). But...

    Displaying Letters via lookup command

    Thanks again for your explanation and the link. The reason I'm entertaining this approach is because I have found that using two processors (18M2 and the main 28X2) are drawing more current collectively, that I prefer. While I could run the OLED from the 28X2, but I have two pinsB that are...

    Displaying Letters via lookup command

    Another question guys, when I'm on the same project. With respect to an OLED display and driving it via Pulsout instead of serout. With the 18M2, the pinsB are used to drive pins D0 to D7 on the display. My question... Is it possible to use different pins from another group. dirsb = %11110110...

    Displaying Letters via lookup command

    Thanks again Alan, I must admit, I wasn't expecting it to hold time that well, from past experience with M2's. I was more surprised that it was gaining time though. I expected it to loose it. I assume it must be a hardware variance. I decided to take your advice anyway and purchase DS3231...

    Displaying Letters via lookup command

    I got around to just doing the clock part based around the Time Variable. It has turned out to be reasonably accurate with the 18M2. Although the biggest inaccuracy comes at night, where we are getting frosts. Through the day its lucky to loose a second @16Mhz. While at night the Picaxe's...

    Displaying Letters via lookup command

    Thanks Alan. I appreciate your insight into the concept. I know it is a wild idea. But if I told you why i'm going down this path, you would think I was loopy;) I do agree this will be difficult. Especially the logging in the outside unit. It too will back up the time information. I am planning...

    Displaying Letters via lookup command

    Thank you guys, Buzby. Unfortunately the 18M2 is hard wired, so using the Hserout isn't possible for me. Alan, I forgot about the prescaler. I haven't used it before. But it sounds like it maybe the only option for lost command time. Just for reference. This is for a clock of sorts. Most...

    Displaying Letters via lookup command

    Hi guys, I there a way to display Letters, when using lookup / pulsout. Rather than using a Serout command? I know of using - serout OLED, baud,(254,131,"",#hour,":",#minute,":",#second,"AM") But what I am wondering. Is there a way to place a Letter in the lookup...

    PICAXE on social media, what went wrong ?

    I'm not on FB or Twitter. But some more good Youtube tutorials on Picaxe's setup and syntax would have been welcome for me in the early days. And may still be useful for people thinking about, or just starting out with Picaxe. There are so many Arduino, Adafruit etc tutorials on Youtube.
