Thinary Nano Every support #125

Closed asferreira closed 3 years ago

asferreira commented 3 years ago

Thinary has a Nano Every "clone" board based on ATmega4808. There is a package in https://github.com/Thinary/ThinaryArduino that adds support to these boards to the Arduino IDE and it seems to work fine. Unfortunatelly, I wasn't able to use it in PlatformIO. I've tried to use the MegaCoreX ATmega4808 and I could build and upload the firmware but it didn't seem to work properly. Is it possible to add support to this board in the MegaCoreX package?

Thanks in advance.

I agree, it would be really nice to have support for those available from a proper core. Thinary is the best of the chinese clone manufacturers. Their nano clones have micro USB, and they make ones with 328PB's in addition to the normal P's......

@asferreira does the Thinary 4808 work with MegaCoreX in Arduino IDE? You say the firmware didn't seem to work properly. Have you tried to select your preferred settings in the IDE menu and ran "Burn Bootloader"? This sets the correct fuses. It might be related to the bootloader fuse bits being set when they shouldn't.

asferreira commented 3 years ago

No, it doesn't work in Arduino IDE also. In my tests I created a simple sketch that blinks the builtin led. It worked using the thinary package found in github on the Arduino IDE, but it didn't work with MegaCoreX on Arduino IDE or PlatformIO. I rewrote the sketch to use port registers instead of the Arduino PIN number and the program did work with MegaCoreX on both platforms. I also managed to work with the serial (USB) monitor, which was accessible using Serial2. The only setting I had to change was the programmer, which I set to JTAG2UPDI.

SpenceKonde commented 3 years ago

That sounds to me like it just uses a different pin mapping.... ?

It would appear that the pin mapping they use is a particularly stupid one, actually. Just with their 328pb nano.... (which didn't break out the new GPIOs) it;s a "snatch defeat from the jaws of victory" design: here's the variant file. https://github.com/Thinary/ThinaryArduino/blob/master/Thinary-megaavr/variants/nona4808/pins_arduino.h

asferreira commented 3 years ago

Indeed! Although the pin's labels printed on the board match with original Arduino Nano Every board mapping, they are mapped to different pins in the MCU. I just figured it out after looking into the pin_arduino.h file in the Thinary's github repo.

MCUdude commented 3 years ago

What happens if you use PIN_PC2 as the pin number, and not 13 when setting pinMode and toggling the LED pin?

MCUdude commented 3 years ago

I've pretty much finished implementing the Thinary Nano 4808 pinout. However, I'd like to re-map the serial numbering so it mimics the Nano Every better. I've ordered a Nano 4808, but it will take several weeks before it arrives.

I found this Nano 4808 pinout over at the Avrfreaks forum: ThinaryTemplate

I'd like to remap the serial pins to something like this. Thoughts?

I’ve been using the same pinout picture as reference to my tests with this board. It seems to be correct, so far! I have no objection regarding the serial pins remapping you proposed. In fact, the remapping defined in the Thinary’s package is quite weird, I didn’t get used with the serial monitor at Serial1.

I've pretty much finished implementing the Thinary Nano 4808 pinout. However, I'd like to re-map the serial numbering so it mimics the Nano Every better. I've ordered a Nano 4808, but it will take several weeks before it arrives.

I found this Nano 4808 pinout over at the Avrfreaks forum: https://user-images.githubusercontent.com/3238730/126153193-7ff5f476-540b-4509-9759-9dd2dccdfbcf.png I'd like to remap the serial pins to something like this. Thoughts?

I’ve manually installed the zip file from the branch nano-4808 on the Arduino IDE, but the nano 4808 board hasn’t showed up in the board list. I also noticed that the Arduino Nano Every board hasn’t appeared either.

I’ve just finished some basic tests and the board worked fine for most of them. Serial and I2C are working fine. Just one annoying thing about the serial interface it that when your program uses the serial monitor, it becomes very difficult to upload a new firmware to the board. I had to reset the board many times and try to upload again until avrdude could write the code. Unfortunately it seems to be expected due to the architecture of the us/serial interface used on the board. I’ve also observed some strange behaviors that I’m not sure if they were expected or not:

Is there any specific test you would like to be done? Let me know If you need something else!

There was a typo in the timer pin mapping that may have caused the weird behavior you experienced. Can you pull the latest change and try again?

I've seen users complain about this elsewhere too. It's just how they have implemented the jtag2updi firmware. Right now, it's only possible to upload to the nano 4808 using jtag2updi through Arduino IDE. I should probably make it possible to choose any programmer since the UPDI prin is exposed anyways. If I were to design the board, I'd probably just remove the jtag2updi chip altogether and use a serial bootloader just like on classic Nanos.

MCUdude commented 3 years ago

I think I've solved the issue where some pins were offset. But does Serial.print print to the serial monitor, or do you have to use Serial1 or Serial2?

I had to reset the board many times and try to upload again until avrdude could write the code. Unfortunately it seems to be expected due to the architecture of the us/serial interface used on the board.

The Nano 4808 pinout variant is using JTAG2UPDI as the default programming option. If you want to use a different programmer for it, connect one to the UPDI pin and upload using the programmer. You can quite easily DIY your own microUPDI programmer if you have an on Leonardo, Micro or Pro Micro lying around.

asferreira commented 3 years ago

I’ve downloaded and installed the updated version of the nano-4808 branch and now all pins are working. Serial monitor is mapped as Serial object. I didn’t need to use Serial1 or 2.

I just got my Nano 4808 in the mail, and everything seems to work correctly according to the pinout. I'm closing this issue and merging the nano-4808 branch into master.

Thinary Nano 4808 support is present in the latest 1.0.9 boards manager release!

tresvdoble commented 3 years ago

The servo.h library does not work with this card, is it planned to put this library that is compatible with the 4808?

adelin-mcbsoft commented 2 years ago

I'd like to make a suggestion for this particular board (Thinary MK II), which I've been testing lately and I'm quite satisfied with. So all in all, the board performs as expected with MegaCoreX.

The only (known) hardware bug, is that you cannot write it, if the Serial writes data to the USB faster than 1 second without delay. Which means that, unless you have a separate programmer (other than the JTAG2UPDI present on board) to write it, you could consider the board virtually bricked if you made the mistake to write to Serial continuously.

As per my previous experience with other boards, I know that you have to pull-up or down a GPIO to enable writing mode (for example, on Espressif Chips you have to pull-down GPIO_0 to enter in writing mode). Though I didn't dig further (yet), I'd expect that this board also expects some GPIO up or down for writing.

So I was thinking that this could be very helpful, as the Serial class could be modified in such a way, that it does not print/write (output) anything as soon as it finds that a specific GPIO (the one that enables writing in our case) has its state modified (up or down, as needed).

This way, there would be no output to the Serial USB anymore as soon as the GPIO state changed, and the board can be successfully written. No more bricked boards.
