Added an additional SPI API function dmaSendAsync which will start the a DMA send of a buffer and return immediately. The next time dmaSendAsync is called it waits if the previous transfer is not complete. Note the buffer is not copied, so ddouble buffering is needed to use this function

SPI update
...
- cleaned up commented out lines
- run-time optimized write and transfer functions
- run-time optimized non-DMA block read routine
- function call order within DMA routines tied to F4 structure - in line
with AN4031, chapter 4.3
- reworked send functions (currently not used, deprecated, but still)

- dmaTransfer adapted for TFT library usage

further optimizations
...
- extend read function to 16bit
- add repeated write the same byte/word a specified number of time
- revert increment option to dmaSend

added part from SD fat lib which enables SPI 2 device write access
...
taken from SdSpiSTM32F1.cpp - Victor's lib, and adapted to support device selection.
To be checked with other libs which are using the SPI lib.

Various changes to boards.txt and some libraries, so that things will compile under IDE 1.6.6 Note. There are still loads of warnings when you compile - which look like they may be caused by the IDE using a new version of GCC, but at least it now compiles

Continued with SPI setModule - still doesnt work when I tried setModule(2);
2015-07-08 11:14:57 +10:00
20a9214291
Some fixes. Works for SD example SPI 1, not tested with anything else. setModule not tested
2015-07-07 20:59:33 +10:00
2e13a1d57e
Initial attempt at SPI setModule - but it doesn't seem to work for SPI2 etc, even when not using setModule to select the SPI channel, when I tested with a VS1053 board attached to SPI2 and SD on SPI1
2015-07-07 07:27:09 +10:00

Alternative / better fix provided by @pico based on work by @victor_pv. Commented out AF REMAP of NSS in spi_f1.c

Added code to 'get' the gpio mode of a pin, and have used it in SPIClass::begin() to store and reinstate the pin mode of the SPI NSS pin. This is a work around for 'features' in the STM32 silicon, which seem to change the GPIO mode of the SPI NSS (hardware - 'Software Select' pin)
2015-06-10 10:25:22 +10:00

Added support for SPI 2 to VS1003 library, and made a change to SPI to support other libs being able to select which SPI they want to use (issue with const in transfer()

SPI updated to eliminate warnings
...
The same write function works for both 8bit and 16bit transfers, so
eliminated the 8bit one and that takes out warnings when the compiler is
not sure of the width. Tested with both ILI libraries (_STM and not STM)
2015-05-27 20:16:15 -05:00
e13b9a0709
SPI DMA functions.
...
Adds 6 new functions: DMA Transfer, DMA 8bit send, DMA 16bit send, write
16 bit int. and mode change to change between 8bit and 16 bit transfer.

Second attempt at SPI::DMATransfer. Now uses separate tx and rx buffers, and I also added code to wait for tx to complete and SPI to not be busy before exiting the function. Note. Operation of rx buffer has not been tested
2015-03-30 06:47:26 +11:00
5f9e8a04dd
Added first pas at SPI::DMATransfer(byte *buf, int length) - and updated ILI9341 lib to use DMA Transfer for fill rect

renamed top level folder STM32F1XX to STM32F1 to correspond to other top level folder names e.g. STM32F3 and STM32F4
