    Using TSOP31240 in parallel

    Corruption from reflections is more likely if using IR sensors of different models or manufacture. Their AGC response and signal latency is likely to have more adverse effect than bounced light. More likely a problem if busking it with random sensors rather than buying however many you need...

    Compact Date Storage & Retrieval

    I am sure there must be an easier way to do it ... but I have no idea how to. But here's T Ikeda's program converted into a Macro which makes it easier to install into a program, which is as far as I got ... #Define EPOCH 2000 #Macro EncodeJulianDate(wJdn, wYear, bMonth, bDay) ; Algorithm...

    Digitech XC4134 Serial to Ethernet

    As lbenson notes the PICAXE download circuit was designed for RS232 and should be fine so long as the 22K is in place. +/-6V through 22K is only +/-270uA which is not enough to damage the silicon despite the voltage notionally being out of spec. This is what I have used to block negative...

    Hippy status, rev 2.0

    I had the 3.1 version from 1995, probably for Win 95 - https://winworldpc.com/product/paint-shop-pro/3x That page suggests there's a 32-bit version but Win 10 won't let 'setup.exe' run. Maybe setup is 16-bit and if I can get it extracted I can copy the files over. That seems to be the...

    Yes, the way they did it wasn't great, could have been better. They appear to have taken the view that anyone buying cheap FTDI modules would have known they were fake because the only way they could be that cheap would be if they were fake; like the the "£5 Rolex" et al. The 'victim...

    Print layout (Slave) til Display OLED modul (16x2)

    Your input order differs from the AXE133 - You have "IN / 0V / V+" where AXE133 is "IN / V+ / 0V". IMO, though it makes the tracking trickier, it would be better to make them match. The order on the AXE133 matches standard servo wiring so it can be connected to boards with a 3-pin LCD output...

    Hippy status, rev 2.0

    That is a common definition but it has generally been accepted as 'any period longer than where the stop bit should be' which is what actually happened when a physical cable was unplugged, the connection broken. Most OS's support turning it on and turning it off, but some will offer a timed...

    Print layout (Slave) til Display OLED modul (16x2)

    And having automatic buffering of received data allows time for more leisurely output to the LCD, the use of 4-bit mode, more processing to be done on escape codes etc. The AXE133 was designed for minimal costs and that dicatated a PICXE-18M2 with the limitiations there are.

    Compact Date Storage & Retrieval

    I am not convinced it is worthwhile doing 'clever maths' when bit fields will cater for 127 years. #Picaxe 20X2 ; Date : 54321-9876543210 ; yyyyyyymmmmddddd #Macro MakeDateStamp(wDateStamp, wYear, bMonth, bDay) wDateStamp = wYear - 2020 << 4 | bMonth << 5 | bDay #EndMacro #Macro...

    Digitech XC4134 Serial to Ethernet

    That would be my opinion as well, or something similar. To have remote programming, so one can keep using Windows and PE6, there are three parts to the solution; something which runs under Windows and presents itself as a Virtual Serial Port which puts what is sent to it on ethernet, and...

    Using TSOP31240 in parallel

    The TSOP3120 datasheet shows the outputs are open-collector with an internal 30K pull-up to +V - https://www.vishay.com/docs/82492/tsop312.pdf - so parallel wiring is possible as inglewoodpete describes. If you had a lot of sensors and the paralleled internal 30K's were being reduced too much...

    Hippy status, rev 2.0

    My trusty XP system finally crashed and burned so I have got with the programme and am using Windows 10 as my primary home system. I will work my way through the sack of adapters I have acquired over the years and see what works and doesn't. for me.. I don't recall any problems with Prolific...

    Hippy status, rev 2.0

    You could well be right; not all chips or drivers support 'break signalling'. It can sometimes be possible to connect a button between the Download Serial In pin on the chip and +V, use that as a 'push to initiate download'. One could probably survive with that in the short term but not ideal...
