Hi. Check the voltage on the button when it is pressed and not pressed.

ok, yes. i did just that. no go. i just got the last one finished. other then a single color oled supplied, it worked on the first go. no issues at all. i did have another dual color oled so i changed

Hi Amie, It does look like the PIC may be the problem. Provided you have loaded the same firmware it should be fine. You could try adding an external 10k? pull-up from RB2 (pin 23) to +5V to see if

the via is clean, and fine. the pic is being stubborn.

ok, here is what i have. ON the pin of 22 i have +5 on the pin 23 zero v. from the via pad to 23 to pin 23 have contact. no zero home. the pad has contact to pin 23 and nothing else, no short. no 5v

All understood. Yes, there should be a weak pull-up to VDD (5V) inferred in the firmware for RB0, RB1, and RB2 (Pins, 21, 22 and 23). If you measure the voltage between GND and the pin it should be

i will check fo b+ . so, you are saying there is B+ on pin 22 and 23? of the pic. the one in the picture is clean. and it works fine. i clean them all and use a 6x loop to go over any of the boards i

Hi, Before you change the PIC it may just be worth checking the voltage on each of the connections. There should be an internal weak pull-up resistor on the RB1 and RB2 lines and therefore with the

so, i have built several of these, only one is not working correct, so, i have ordered some of the pic16F1938 and going to replace it. nothing else has a issue. has to be a pic issue. also, on the via

Hello, i have put togethe 4 kits now, all work but one the bypass wont work properly, sometimes it will and then just wont, re booted several times, the wires are done right on the thru pads using

hi Hugo, look here: https://github.com/Dfinitski/N7DDC-ATU-100-mini-and-extended-boards/tree/master/ATU_100_EXT_board/ATU_100_EXT_board_User_Manual 73, Immo

Hi Immo, Thanks very much. In fact, I encounter this random issue even without the presence of HF ! I"m going to try to add these capacitors. In addition I have just ordered a new display. 73s

hi Christian, I had another issue with an ATU100, where the OLED made noise every 1080kHz up to 30MHz... Search the regulator on the back, then do a try... ( mine is a 0.96inch OLED) I know, where RF

Can you confirm that my interpretation is correct ? Could be usefull to install a 100nF capacitor on the buton as describe on this link :

Hi David, Can you explain a little bit more about capacitors installation. Thanks for your help because I have the same issue with the 1.6? and sometimes with the 1.5 version of firmware. 73s

Hello folks, just received an ATU-100 (not the "M") in my post box and am trying to figure it out.? There was no manual in the box and the web searches are returning only documents which don't

Hello,Thanks for responding. I ordered some BAT41 diodes that should arrive in the next couple days.?I'll let you know how it goes.?Thanks again for all of your help!RyanSent from my Verizon,

Sorry Ryan, I missed, that T2 of the bridge goes just to GND. So 0.2ohms should be ok... not 25, as I said first. Make another measurement across the diodes, both ways. You should see a difference,

hi Ryan, you should change them. Do the measurements again when both are desoldered to be sure, that not a capacitor has a short way… This also is possible. You will see. 73, Immo

Hello?Sorry. 87.2ohm on one side and 0.2 on the other side for both diodes.Sent from my Verizon, Samsung Galaxy smartphone
