Re: ATU-10: programming the PIC16F1454?
Hi Tony,
I can't understand your comment re the wire to supply the voltage to the programmer. All you need are the five connections from the PICkit 3 to the five points (J2) on the ATU-10 PCB. You shouldn't require any other wires. You do need to power up the ATU-10 board via its USB port so the PIC can get its supply. When it comes to the MPLAB suite you need the IPE app for programming the device, not the IDE which is used for creating the code to put on the PICs. If you've downloaded the suite it should be on your PC somewhere, normally both app shortcuts appear on the desktop during the installation unless informed not to. Start up the IPE, go to Settings/Advanced Mode and enter the password, 'microchip' if it's a fresh install. Click on Power, under voltage options 'power target from PICkit 3' should be selected already, select 3V375 from the voltage level drop-down options. Under programming options, the 'use low voltage programming' option is unchecked, and change the programming method drop-down to the one that says 'recommended'. Now click on the 'Operate' tab, the device drop-down selection should be the 1454, the tool should show the connected PICkit 3. Click on connect which should, after a short period, show the device ID of the connected PIC. Add the hex file to the appropriate file selection window below the row of big buttons and then click the 'Program' big button. Should only take about 10s or less to do its thing and there it is, one programmed 1454. You can now carry on with the build. Hope this helps get you sorted. All the best. Robbie M1ROK |
Re: ATU-10: programming the PIC16F1454?
Dear Robbie,
Thank you for the comments! My previous attempts were made WITHOUT the wire that would supply the voltage from the programmer, so the chip was powered with 3,3 volts throughout. (I've downloaded, installed and tried to run the MPLAB X IDE v6. It is SO huge - I was lost immediatelly. Where is the programming functionality there? I doubt it recognised my PICkit 2 clone either...) Warm regards, Tony |
Re: ATU-10: programming the PIC16F1454?
Tony, connections to the ATU-10 PCB were 1 to 1, 2 to 2, 3 to 3, 4 to 4 and 5 to 5. There's a 6 on the PICkit units but it isn't used here. Pin 1 on the ATU-10 PCB is marked with a 1 and is also a square pad so just keep all five connections in line between PICkit and PCB.
In MPLAB you can select family type as midrange, but on mine I didn't need to, just select the 1454 from the other dropdown - if it's not there then yes, select midrange family which should make it appear. If you've set power in the Advanced menu for 3V3, plus the other selectable option is set to the one that mentions 'recommended' (mine was defaulted to the other option), you should be good to go. That's assuming any previous attempts at programming the PIC whilst it was set at 5V haven't damaged the 1454... Robbie M1ROK |
Re: ATU-10: programming the PIC16F1454?
Dear Robbie,
I'm about to add a wire from the programmer's pad #2 to VDD pin of the PIC16F1454 chip, may be - temporarily - removing the LDO stab (to avoid possible damage by reverse voltage). I thought the programming fails because of undervoltage (3,3 vs 5,0 volts power). Am I wrong? Warm regards, Tony |
ATU-10: programming the PIC16F1454?
Hello!
My PICkit-2 has just arrived, neither the nor the recognise this clone. Only the (taken from ) handles the programmer and detects the PIC16F1454 chip (ID 3020). All I could do so far - is only to erase the initial (the "XPRESS" that came with PIC16F1454 from the DM164142 board) firmware. It tries to program but fails to verify the programmed contents. Could that be because the chip is powered with 3,3 Volts (from ATU-10) rather that with 5 Volts from the PICkit 2? Thank you in advance. Warm regards, Tony |

This is known problem of this tuner. You have to add decoupling caps and ferrite beads to the buttons wires

开云体育Thank you both for this additional info. Mine does have yellow relays. I'll cautiously test running TX through it when powered off, and see how the radio responds (I'm using an antenna that is resonant on 40m in my configuration, so I'll test there.)73, Joe KF7MIX On 5/24/22 19:38, VR2XLQ wrote:

Re: Bypass for ATU-100 with only one button?
Yes, if the relay is non-latched type (usually yellow in colour), it will be reset to off stage when no power is applied. Mine version is ATU-10, it uses latched type (white in colour). It keeps in the previous position when power off. The adv is it uses less power and keep the status, the trade-off is the cost of the relay. Not sure if there is any latched ATU-100 model on the market or you can change it to latched type relay yourself for a trial. 73 de VR2XLQ 在 2022年5月25日週三 上午6:06,Colin Kaminski <colinskaminski@...> 寫道:

Re: Bypass for ATU-100 with only one button?
The ATU-100 has non-latching relays. It should reset to a pass through configuration when off but I haven’t tested mine.? The bypass switch is momentary contact. The display shows when you are in tuning mode or bypass mode.? Colin K6JTH? On Tue, May 24, 2022 at 11:38 AM Joe - KF7MIX <joe@...> wrote:

开云体育I readily admit that I'm very much an amateur when it comes to schematics, so forgive me one more question:I notice that if I listen to a band with the ATU-100 in-line but powered off, the RX seems to be just as good as if I connect my antenna directly to the radio. Why is this? Is there danger in transmitting if the ATU-100 is powered off? Thanks for any details you can provide, 73, Joe KF7MIX On 5/23/22 20:09, Joe - KF7MIX wrote:
Excellent, thank you! I'll get in there and see if I can find that pad. In the schematic, is that a toggle switch? I can't find the schematic symbol online... is it saying that I'd switch that pad to ground to enable bypass (versus a momentary pushbutton)? |

Re: Bypass for ATU-100 with only one button?
Hi Joe, I have the button but when I was making it I just soldered a wire to the pad marked RB2. It is close to the processor chip on the side of the board close to the controls. I am pretty sure I just ground it with the switch. Here is the schematic. Colin? K6JTH |
Bypass for ATU-100 with only one button?
Joe - KF7MIX
Greetings all. I have a question, about an ATU-100 (pre-built Chinese version... I had to solder on new SO-239s, the ones it came with were horrible):
This version of the hardware only has one button connected, which is labeled "TUNE". It works for the TUNE and RESET functions, with long and short press. I'm testing it on both a G90 and an FTDX10, both of which have internal tuners (the G90's internal tuner seems to work quite well, but the FTDX10's internal tuner won't tune up on anything higher than 20m for me.) On the FTDX10, I really only want to use this for rare occasions when I need 17m,15m,12m, or 10m. For 80m/40m/30m/20m, the internal tuner works fine. However, this tuner has no "Bypass" button. Should I disconnect this little tuner when I'm not using it? Or do these types fallback into a bypass mode when powered off? Thanks for any tips or info. 73, Joe KF7MIX |

Re: ATU100 with memory
There are 256 bytes of EEPROM. You would need to have a frequency counter and make a lookup table. It’s not much room.? Colin K6JTH?
