Nice chart, should be very helpful. Thanks!

Awesome work!

Can you put it on github so we can subscribe to updates?

It is now up at github project:

Hey guys, anyone know how to access these alternative function especially from the JMISC connector???

Figure-2:

Fig-1 compiled from Table 28 and 29 of datasheet shows: 13 alternate functions for the default PB7. This is same as #1 @KurtE.

Fig-2 compiled from Table27 of the same datasheet shows: 16 alternate functions for the default PB7.

Why is there discrepancy?

Figure-3:

Fig-3 says that digital functions D0 (PB7) and USART1_RX function could be obtained using Arduino IDE.

To use the alternate functions available on the PB7 pin, we rely on the HAL (Hardware Abstraction Layer) libraries provided by STMicroelectronics. HAL functions configure the MCU’s registers internally, allowing us to enable features without needing to manipulate the registers directly.

Or you can cheat like heck :smiling_face_with_horns:
For example I have a sketch that works with the SPI pins that are on the JSPI
connector.

The test sketch is up at:
Arduino_UNO_Q/Test Sketches/fillrect_test/fillrect_test.ino at main · KurtE/Arduino_UNO_Q

The sketch has a function:

void set_gpio_pin_mode(GPIO_TypeDef *port, uint8_t pin, uint8_t af) {
  // Set the MODER = could be done in fewer steps
  uint32_t moder = port->MODER;
  uint32_t mask = ~(0x3 << (pin * 2));
  moder = (moder & mask) | (0x2 << (pin * 2));
  port->MODER = moder;

  if (pin < 8) {
    port->AFR[0] = port->AFR[0] & ~(0xf << (pin * 4)) | (af << (pin * 4));
  } else {
    pin -= 8;
    port->AFR[1] = port->AFR[1] & ~(0xf << (pin * 4)) | (af << (pin * 4));
  }
}

And in setup, I have:

  // Or for ST7796 3.5 or 4"
#ifdef USE_JSPI_PINS
  // they are pins c2, c3, d1
  set_gpio_pin_mode(GPIOC, 2, 5);
  set_gpio_pin_mode(GPIOC, 3, 5);
  set_gpio_pin_mode(GPIOD, 1, 5);

  pinMode(11, INPUT);
  pinMode(12, INPUT);
  pinMode(13, INPUT);
#endif

Which set those pins to SPI mode and I removed the default pins 11-13 as being
SPI pins.

But of course you still need the code that drives the pins.

Yeah i tried using the HAL library in the sketch but the arduino core doesn't allow me to do so, Do you have any working code to sue that??
