ChibiOS Free Embedded RTOS

Fixed in trunk.

Hi Wolf,
The hook has been added in trunk.
The function gets the instance pointer and the character.

Hi,
The errata states that issue occurs only after a simplex SPI transmission.
ChibiOS SPIv3 driver uses duplex for send and receive with DMA (the receive side acts to terminate a send transaction).
For polled a simple direct write of transmit register is followed by waiting on receive.

So it seems ...

Hi,
That special NONEMPTY pseudo value is for MCUs with large FIFO (e.g. H7).
One eighth of an H7 USART FiFO is 2 characters so in a use case with char by char input (like shell console) there is no input on each keystroke if a FIFO threshold is used.
The line idle takes care of re-enabling the ...

Hi Alex,
I have a prototype NUCLEO H753 board with 2 x Winbond W25Q512JV parts attached.
One is normal SPI connected the other is QSPI connected.
Both Winbond chips are on breakout boards with 10cm Dupont leads back to Nucleo.
This is not ideal of course and to make this work I put snubbers (47R ...

In The F4 series you also have DMA double buffer mode.
See Ref Manual 10.3.9 Double buffer mode .

So making use of this with the two DMA buffers allows processing (or copy out) of one DMA buffer while another packet is incoming on the other buffer. Not unlike what you would do with circular but ...

Fixed in trunk and 21.11.4

FYI #define BOARD_OTG_NOVBUSSENS has no effect on the internal STM32 boot loader (only on the ChibiOS driver).

AN2606 provides details on the internal STM32 boot loader.
See m
I expect from a quick look at AN2606 that you will need to have the VBUS pin connected for the STM32 boot loader to detect ...

Addressed the SPI dummy variables as well by allowing the entire driver structure to be located in non-cache.
Drivers now have this for allocation...

/** @brief SPI1 driver identifier.*/
#if STM32_SPI_USE_SPI1 || defined(__DOXYGEN__)
SPI_SPID1_MEMORY SPIDriver SPID1;
#endif

So just define ...

It can be closed now.
