ATmega8515 I2C #28

Closed ITstreet1 closed 1 year ago

ITstreet1 commented 1 year ago

I just walk through the datasheet. There is no I2C for this MCU, or I am wrong?

And an additional question, by using your package support, can I burn the bootloader and use it just like any other ATmega MCU, say 328p?

MCUdude commented 1 year ago

The ATmega8515 (and ATmega162) does not have i2c support.

And an additional question, by using your package support, can I burn the bootloader and use it just like any other ATmega MCU, say 328p?

Yes, the Optiboot bootloader works exactly as you would expect from an ATmega328P.

Then, I believe I can use some softwire lib, but which pins should be suitable?

Sure, but that's not up to me to decide. The ATmega8515 is very old and does not have PCINTs on the ports. ATmega162 is newer, but both of these are not very common, so I doubt you'll find an Arduino library that will work for these.

One thing you can try is to port the TinyWire library used with ATtiny13/MicroCore: https://github.com/MCUdude/MicroCore/tree/master/avr/libraries/TinyWire

MCUdude commented 1 year ago

A quick Google search reveals that this library is generic and platform-independent. It may work with ATmega8515.

ITstreet1 commented 1 year ago

That one was in my mind. Thank you for your time. I just want to give it a try for an MCU I have. I will post a schematic later, just to have someone check if I made a thing or two wrong.

Schematic_Clicker ATmega 8515_2022-10-21.pdf Something like this. ;)

MCUdude commented 1 year ago

The schematic is a bit messy and hard to read but appears to be OK. I'm sure it will work as long as the schematic symbols are correct!

ITstreet1 commented 1 year ago

It is messy. It is half an hour design. LOL. It should use MikroE mikroBUS. As for I2C, I used two sets of pins just in case one won't work.

ITstreet1 commented 1 year ago

OK, So, it is soldered but stuck on the bootloader. I connected Nano with this one.

Nano - 8515

5V - 5V GND - GND D10 - RST D11 - MOSI/PB5 D12 - MISO/PB6 D13 - SCK/PB7

UPDATE!!!!

I found a solution here: https://forum.arduino.cc/t/avrdude-stk500_disable-protocol-error-expect-0x14-resp-0x10/590824

Besides, as I used Nano SPI lines from headers, rather than from ICSP, I uncommented line 81 -> #define USE_OLD_STYLE_WIRING

Also, I added a 10uF cap on RST and GND on Nano. The bootloader is done:

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

It's most likely a hardware issue. Are you trying to upload your code using your Arduino as ISP or using the onboard USB to serial adapter?

If you're using the ISP programmer, go to Sketch >Upload Using Programmer in the Arduino IDE menu

Ok, I burned the bootloader again using Nano. I have an LED on pin D0(PB0) which started blinking after the bootloader is burned. More like two fast blinks, than a sec delay. After restarting, it stopped. No simple blink sketch, all wires the same, nothing pulled out.

Case 1: Nano as ISP programmer.

avrdude: stk500_disable(): unknown response=0x12 the selected serial port avrdude: stk500_disable(): unknown response=0x12 does not exist or your board is not connected

Case 2: Nano as ISP programmer with a CAP on RST and GND.

avrdude: stk500_disable(): unknown response=0x12 the selected serial port avrdude: stk500_disable(): unknown response=0x12 does not exist or your board is not connected

Case 3: Using onboard CP2102.

It holds on Uploading... for a long time. Meanwhile LED on D0(PB0) is blinking the same way as I mentioned above. After a while it throws:

Settings are external 16MHz, BOD 2.7V, EEPROM retained, LTO disabled, and Bootloader YES(UART0). The programmer is left selected Arduino as ISP if that matters.

What else should I try?

Offtopic... I have almost the same issues on ATemaga328p, but the issue is closed. :( https://github.com/MCUdude/MiniCore/issues/215#issuecomment-1365378976

Well, I don't know what more I can do. The Optiboot bootloader is proven, and I have working boards with both the ATmega8515 and ATmega328PB and Optiboot works perfectly fine. You have custom-designed boards, and neither of yours works. I'm very sure it's hardware related, but since I don't have your hardware, there's little I can do other than look at your schematic.

But does the USB to serial adapter work? Does the echo sketch below work when you upload the program using your ISP programmer?

int incomingByte = 0;    // for incoming serial data

void setup() {
    Serial.begin(9600);    // opens serial port, sets data rate to 9600 bps
}

void loop() {
  // send data only when you receive data:
  if (Serial.available() > 0) {

    // read the incoming byte:
    incomingByte = Serial.read();

    // say what you got:
    Serial.print((char)incomingByte);
  }

}

How to check the communication between CP2102 and 8515? On 8515 I can not upload any sketches.

Any idea what hardware onboard to check and how?

How to check the communication between CP2102 and 8515?

Upload the test sketch I posted using your ISP programmer. Open the serial port at 9600 baud, and try to send something. If what you sent gets printed on the screen, it means the microcontroller receives the data correctly and sends it back correctly.

On 8515 I can not upload anything. Except for the bootloader.

Yes, you can. You can upload the sketch using your programmer.

I just couldn't upload a sketch using Nano as a programmer. The output I posted above.

Anyway, I resoldered both the 8515 and the CP2102, and now it works.

I must mention I already did it several times, and I use a Miniware soldering plate. Obviously, the QFN package is a little tricky to even see if is it ok soldered. But I don't think it caused the issue to upload a sketch using Nano as I can upload the bootloader. Something wasn't well soldered for sure.
