Any general discussion around the firmware, what is does, how it does it etc.

i havent come across that problem. but im using my own custom stm32f407 board, i did find that the default board pin configuration is used and it crashed my board, i think if you go direct to the TS settings and reselect the blackstm32 and reboot may be a option to try before doing anything.

Well, reselecting STM32 board didn't change anything, so I selected Speeduino v0.1 (the original configuration it showed me after the flash) and it stopped communicating. Apparently it wrote that settings to the external flash and now it tries to use a different UART or something. After some some datasheet check I managed to write a quick flash erase tool, that brought the board back to life. And to my surprise, it's not all INVALID, but mainly BOARD DEFAULT. That means the flash didn't arrive clear, but with some data stored inside. There are still some INVALID I/Os, but I guess they should be user assignable.

EDIT: After manual setting programmable output pins to some port and back to disabled state, all the warnings went out. So it looks like, it will need a default tune to come with the speeduino library.

You are seeing invalid, because the STM32 pin mappings are usually in form of "PB0" or "PE5" etc. but arduino mega pin mappings are just number. Or A and number for analog pins and that's what the TS is expecting.

I did work around the issue by modifying the variant files in the core so that normal arduino pin numbers match what is the stm32 pin used for that purpose (because the board has the stm32 form factor). So in that case, when I now select pin3 for example in TS, it's correct pin in the board. And the I/O summary also works as it should. Also the critical pins like SPI and USB ones are mapped to pin numbers that you cannot access in TS, so you can't brick the board if for example you accidentally use USB pin for idle for example. Or select wrong board.

And would you mind sharing those modified files? I guess it would be useful for more people.

didn't think of the pin settings, I have my own pin defines so i didn't have the same problem.

Heureka, I've found the pin definition in the init.ino file. Now it makes all sense ;)

EDIT: It's way more complex. For example the Baro input doesn't work at all. I've found, that there is also several settings in .ini file for TunerStudio. Apparently the key is "Board default" settings, however in case of Baro input, it does nothing.
In init.ino file, there is
Code: Select all
pinBaro = PB1; //ADC12
so I would expect it should work, but it doesn't. It still takes a floating average from MAP value, even though I've set external Baro sensor to YES in pressure sensors calibration of TunerStudio.
Any ideas, where to look for the problem :( ? Thanks.

@Trinom The board defaults is what i usually use. I also always choose Black STM32F407VET6 V0.1 (Last one in the board list from TS) This one is compatible with my own board. The pinout is case 60: in init.ino see:

Be careful with programmable outputs/inputs these can make the board lockup in many ways. If you for example choose pin 20/21 for some other function the USB stops working. So Just disable them all if you starting to explore the firmware.

Thanks for the reply. I am aware of the settings in init.ino, but I don't need to change anything at the moment. My only trouble is, that the external baro isn't working for me and I don't know, why. It should use PB1, but I don't see any change in TunerStudio.
//******************************************
//******** PORTB CONNECTIONS ***************

// = PB0; //(DO NOT USE FOR SPEEDUINO) ADC123 - SPI FLASH CHIP CS pin
pinBaro = PB1; //ADC12
// = PB2; //(DO NOT USE FOR SPEEDUINO) BOOT1
At this moment, I have just a potentiometer hooked up between 3V3 rail and GND with output connected to whatever pin I need, so I can test all the inputs. The rest of the inputs work fine for me, only the baro input (PB1) doesn't. The input is set as "board default", which should not override any settings. In fact, it behaves as MAP input copy with floating average over huge amount of samples.
