Adafruit LoRa32u4 Pins #212

Open McrESP opened 1 year ago

McrESP commented 1 year ago

I'm using ATmega a 3.5" touch screen and a Adafruit LoRa radio as a remote gate and kennel opener. It works like a charm so thank you for providing all the tools needed to make it happen. But now I need to make it much more compact and portable by using a Adafruit LoRa32u4 and a battery backup. Here are the pins I'm using: // adapted from LCD_ID_Reader from http://misc.ws/lcd_information // controllers either read as 16-bit or as a sequence of 8-bit values

//-- Arduino UNO or Mega 2560 Plugged as shield

define LCD_RST A4

define LCD_CS A3

define LCD_RS A2

define LCD_WR A1

define LCD_RD A0

define LCD_D0 11

define LCD_D1 12

define LCD_D2 2

define LCD_D3 3

define LCD_D4 5

define LCD_D5 6

define LCD_D6 9

define LCD_D7 10

And here are the results from LDC_ID_readnew:

Read Special Registers on MCUFRIEND UNO shield controllers either read as single 16-bit e.g. the ID is at readReg(0) or as a sequence of 8-bit values in special locations (first is dummy)

Do these results look like the wiring is correct and if so is there a special for the 32u4?

Thanks for any help

prenticedavid commented 1 year ago

Your first regs look normal. But 0xDA, DB, DC look wrong. Are you sure that your wiring is correct ?

What ID is returned when you plug the Shield into a Uno ? Run LCD_ID_readreg.ino on the Uno. Compare the result of your custom wiring to the "known" result from the Shield + Uno.

David.

McrESP commented 1 year ago

David, Thanks for getting back to me so soon. I'm doing something wrong for sure. I double checked the wiring and it looked good. I don't have an UNO so I tested it on a MEGA2560 and the results are way different.

Any suggestions?

prenticedavid commented 1 year ago

I don't believe you. Have you plugged the Shield into the Mega2560 as Nature intended?

Have you used the defines that come with the library installation ?

David.

McrESP commented 1 year ago

You are absolutely right. I forgot to change to pins back to the MEGA2560 here is the serial output with the correct pins.

prenticedavid commented 1 year ago

There you are. A regular ILI9341. Which is 240x320 and very unlikely to be 3.5 inch diagonal.

reg(0x00D3) 00 00 93 41 ILI9341, ILI9488

Anyway, check your 32u4 defines. Run the sketch. When you get the same report as Mega2560 paste your defines.

I will write the appropriate SPECIAL for you.

David.

McrESP commented 1 year ago

You are correct, it's a 2.8" that i was testing with. Switching to the 3.5" now.

McrESP commented 1 year ago

David, Thanks for all the help with my project but I really screwed this up. I forgot about the logic levels on the 32u4 being 3.3v and the LCD levels being 5v. I only have 1, 8 bit logic level converter so I'm putting the project on hold till I receive another. Thanks again and everything works great on the MEGA.
