Well, I tried a couple of things myself before returning it to you. The calculator didn't power up, the red LED didn't turn on at all and several attempts at reflashing, also with the original setup that used to work before, were unsuccesfull. So something definately happened. When you returned it the first attempt at flashing was succesfull. Thanks again for re flashing the bootloader! |

Your ACT was the only one until now, that had to be reprogrammed, and this could indeed have to do with strange signals at the programming lines. I hope this will remain a single event. I don't like to get headache. Bernhard That's one small step for a man - one giant leap for mankind. |

RE: The HP 34E Ir with PANAMATIK ACT
Just for showing, that I am working on it and there has been some progress in making vinyl overlays.
These are is the designs for the HP-29E and HP-34E. HP-29E will be available first. If it is verified, that all button holes are suitable and the vinyl material is OK, we will order the next overlays. Bernhard That's one small step for a man - one giant leap for mankind. |

Nice job.
The overlays will sure add to the usefulness of the calculator. Would the next batch be the 67 :-) Tanks Bernhard |

At microcontroller speeds it's possible for Vcc to make contact before the Tx pin. USB is designed to be hot-plugged, consequently the power pins are longer and make contact before the data pins. I've installed a micro-USB receptacle inside the battery compartment and wired the connector so Gnd and Tx are connected to the long pins and are assured of making contact before Vcc. Micro-USB breakout board positioned with double-sided foam tape. https://drive.google.com/open?id=0B-GPxm...lpiQTJmWTA Silicone adhesive added for strength. https://drive.google.com/open?id=0B-GPxm...jJodjdJQkE All wired.

Cable unplugged. https://drive.google.com/open?id=0B-GPxm...k1oUzVPTG8 Cable plugged in. https://drive.google.com/open?id=0B-GPxm...ERMeTdUTVk Here's the problem. The ACT won't program when plugged into the 25. Unplugged it programs fine. Dave |

Haven't got answer for you, but did you see the first two pages of my PDF at Bernard's website, I only ask as it looks like you have a single malt on your last photo!
Cheers, Geoff |

Yes, I did. It's important to follow protocol. I believe the problem is because I have a 3.3V cable. I'll need to investigate. Dave |

Hello Dave, Your idea to place the USB/RS232 converter inside the calculator does not match with the constraint that the ACT 5-pin connector has to be connected AFTER the RS232 TX pin has been pulled to low level. See ACT manual description. I assume that the TX voltage level of your converter is undefined at power up and therefore you can enter the bootloader only by chance. The sequence must be: plug in converter, then start flash update application and select COM port, then connect to ACT with TX pin before or simultanuously to VCC. I'm sorry that this at the first glance elegant idea cannot reliably invoke the ACTs boot loader. To follow Geoffs protocol is however the correct idea.

RE: The HP 34E Ir with PANAMATIK ACT
Your up,late!
Catching up to speed on FRAM flashing. Could be 3.3v cable but nominal range is 3 to 5v if I am not mistaken. You say it flashes outside but not when plugged into the 25 PCA. could there be a draw in the chip to the PCA that is interfering? Cheers, Flux is your friend and protocols are important. P.s. Thanks for your work on the FRAM project, extremely helpful including the toolkit! |

Hi Bernhard, No, I'm following the constraints. I'm using a 3.3V FTDI cable and have followed the color-coding in my wiring to the new ACT. As you can see, Tx on the orange wire is connected to pin 5 on the USB connector and Gnd on the black wire is connected to pin 1. These are the long pins that make first contact, per the manual. When the plug is inserted fully Vcc makes contact and the LED lights every time. What happens is the downloader loses communication with the ACT at varying intervals during download. Also, that I can program the new ACT by unplugging it would indicate that the cable is wired correctly. I suspect the 25's PCB is loading down the 3.3V regulator in the cable. There are two possibilities that I will investigate that are due to a mix up I made when ordering the cable. The bottom line is I ordered the 50mA 3.3V cable rather than the 250mA cable. My cable might not have enough current to power the new ACT and the connected circuitry. The other possibility is that I need a 5V cable. I'm not familiar with the 25's circuitry but by hooking up a bench supply I can determine which condition is causing the problem. I think Harald used a 5V cable and had no issues. Dave |

(10-04-2015 07:03 AM)Dave Frederickson Wrote: No, I'm following the constraints..... You are right! If LED lights up then boot loader is entered. I delivered always 5V cables with the ACT update kit. This should work best, but I cannot guarantee whether the HP power supply doesn't interfere when the ACT is plugged in. Try! Bernhard That's one small step for a man - one giant leap for mankind. |

I offer the cable with USB/Converter together with the complete ACT Ir version with Update kit. Because I need the same soldering time like everybody else for preparing this version, it is more expensive. The detailed instructions in the manual are made for all ACT users, who want to save costs. Bernhard That's one small step for a man - one giant leap for mankind. |

Following the instructions in the manual I built one, but it probably would have been simpler if I had bought one, instead. I'm just trying to understand the products and pricing. Your website lists the 25E and 25E Ir upgrade kits at 80 and 139 euros. Is that with or without the programming adapter? I would not need to purchase another programming adapter for a second upgrade kit so I would expect to see pricing both with and without the adapter. Also, is the adapter available separately? Dave |

Hi Dave, 25E is without adapter , 25E Ir is with modified ACT and adapter. Please understand, this it primarily a repair kit for do it yourself. If you buy the Ir Version it includes the update kit as a bonus. The cheaper version doesn't give you update possibility, except you build it yourself. I do not sell USB/RS232 adapters seperately, because you can get them everywhere very cheap. I did not have a customer who bought two 25E Ir ACTs. If so, perhaps he will get two adapters, which indeed doesn't make sense. Bernhard That's one small step for a man - one giant leap for mankind. |
