reprogramming atu-100 #22

Open olson339 opened 4 years ago

olson339 commented 4 years ago

Need some help with the i2c reprogramming. I have a 1602 LCD with a i2c backpack. I used i2c scanner to find out the address, which is 3F. I changed the address using a PIC 3 and wrote the change to my ATU-100. Connected the LCD, background light comes on along with 16 square blocks on second row. I readjust the brightness but no readable display. I am using ver 3.0 of your frimware

Dfinitski commented 4 years ago

Hi. Your I2C address scanner gives you 7 bit address, but the tuner board uses 8 bit address. As you can reed in the manual, "The port extension board for display 1602 made on the PCF8574AT chip has the address 7E, on the chip with the “T” index - 4E. " So no any ambivalent understanding which address you have to use.

olson339 commented 4 years ago

so the scanner shows 0x3F. I enter 3F in cell 00 of the EEPROM. Should the entry be different

Dfinitski commented 4 years ago

Did you read my previous message ? What kind of chip is used in the "backpack" of LCD ?

olson339 commented 4 years ago

yes I read your previous message - the chip on the backpack is PCF8574AT

Dfinitski commented 4 years ago

Excellent, your I2C address is 7E.

olson339 commented 4 years ago

ok thanks

Dfinitski commented 4 years ago

Please check the indication while transmit a power. Tell me if you'll see something wrong.

olson339 commented 4 years ago

The tuner is working but I haven't added any buttons yet for auto/bypass

Dfinitski commented 4 years ago

Can you confirm this behavior ? https://www.youtube.com/watch?v=mUfD4gnzswc&t=1s

olson339 commented 4 years ago

I ran the tuner using my 7300. Display worked correctly from star, tune, operate

Thank you for the help. you can test the newest firmware https://drive.google.com/file/d/1sCYbo3DPGjM-r94aqZJpuZqGIvasgv6K/view if you want.

valantis-chios commented 4 years ago

Hi, I would like to inform you that the DIY kit that I bought has the same problem as described in the video. Firmware is 3.0. what do you propose to do? I am using lcd 16x2. I am waiting to receive pic programmer to check the hex and eeprom. Thanks in advance

Dfinitski commented 4 years ago

Hi, the 3.1 firmware version should work fine. Use a Pickit 3 to change the old firmware. If you will have some problems with 1602 LCD please tell me know ASAP.

Hi, What kind of chip is used in the I2C extender of your LCD display ?

valantis-chios commented 4 years ago

Hi, the chip is PCF8574T

Dfinitski commented 4 years ago

Thanks. I will order LCD with this chip and check this by myself. I can not find the problem in the code also other users report about good work with LCD.

One more thing, how does the type of display affect the tuning process?

Dfinitski commented 4 years ago

I is not matter, you can use the tuner even with no any displays, it is only an option.

Hi, I rewind tandem match and the problem with tuning seems to be solved ( maybe there was a short between filament and ferrite). But the problem with no swr indication still exist.

Dfinitski commented 4 years ago

The LCD will come to me next Thursday. I will see.

Hi. I have bougth randomly an LCD with PCB8574T expansion board on Ebay, I2C address is 4E. Everithing works good. I tried to find mistakes in the code also, many times, but I don't see anything wrong.

Dfinitski commented 3 years ago

People, watch this video https://www.youtube.com/watch?v=vWtbs4n4ewo&t=18s If somebody knows what is going on - tell me know, I will fix it.

valantis-chios commented 3 years ago

Hi, I have the same problem like no 2 and no 3 lcd( no swr indication). Tuning possess is ok. It really don't affect my transmission.

Dfinitski commented 3 years ago

Hi. Order the chiepest LCD on Ebay or Aliexpress, should to work. I don;t know what is the reason, so I can't resolve this problem. I don't have a strong expirience with this kind LCD, i have no idea what is going on. But definatelly those LCD have some differences.

owenaggi commented 3 years ago

help i dont understand what i have done i have the picket 3 and ext board i wanted to use it on low power when trying to reprogram i have some how deletet the pic and now when i try to program the pic picket 3 tells me that there is insuffichet memory please tell me a what i did wrong and if possable how to fix it

hello, I made a connection with 1602 LCD, I2C PCF8574T converter, but the 7805 transistor in the circuit supply is overheating, I could not solve this problem, why does the 7805 get hot? :(

Dfinitski commented 3 years ago

Hi. Everything works good but 7805 is hot ? What is the voltage rate of the relays ?

1602 LCD screen gets hot when I plug it in, No problem with oled display.

Dfinitski commented 3 years ago

So check the connection, power voltage polarity.
