Arduino for STM32

watchdog ? When it expires you can do some stuff.

I don't understand your question?
What do you mean by "hold the boot" ?

Hi @trimarco232
LPUART1 has some constraint around clock vs speed.

/*
* Note that LPUART clock source must be in the range
* [3 x baud rate, 4096 x baud rate]
* check Reference Manual
*/

@fpiSTM just IMHO, I think we can use PA4-PA7 for the default SPI pins on c011 as the '8 pin' chip can't practically use SPI Right, physically not possible. But those file are automatically generated and have no info they shared the same pins so hard to change it. As usual, this is a default(generi...

Sketch has not been updated after SPI rework.

There is an issue in your setup as you used: Wire.setSDA(PA5); Wire.setSCL(PA4); But they are not I2C pins based on the PinMap_I2C_SDA array you provide. The "PYn_R" pin is remap pin that's all but when you remap some other "PYn" pins will not be available. About D14/D15 it exist...

Hi geologic Looking at the library, it seems you used Software SPI. https://github.com/adafruit/Adafruit-PN532/blob/f4e1a91afd0163d8601b243ddcbb2a580da6552a/Adafruit_PN532.h#L143-L145 Which relies on https://github.com/adafruit/Adafruit_BusIO/blob/master/Adafruit_SPIDevice.h So i guess there is an i...
