Roger Clark 0ec837f08c Fix for uninitialised vars in dmaTransfer and dmaSend (as detailed by victor_pv) 2015-07-28 12:00:16 +10:00
Roger Clark 07ba8f279a Updaded SPI with update from VictorPV 2015-07-26 04:58:12 +10:00
Roger Clark fc50831843 Continued with SPI setModule - still doesnt work when I tried setModule(2); 2015-07-08 11:14:57 +10:00
Roger Clark 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
Roger Clark 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
Roger Clark 501da92986 Added a line in SPI.cpp to default the bitOrder to MSBFIRST 2015-06-25 09:36:23 +10:00
rogerclarkmelbourne 7d7f113f63 improved vasillis's SPI 2 demo 2015-06-12 09:49:00 +10:00
Vassilis Serasidis 1a676200f7 Example of using the SPI_1 and SPI_2 ports on STM32F103. 2015-06-11 15:01:45 +03:00
Roger Clark 657d6dae02 Alternative / better fix provided by @pico based on work by @victor_pv. Commented out AF REMAP of NSS in spi_f1.c 2015-06-10 10:33:13 +10:00
rogerclarkmelbourne ece9c3681d 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
Roger Clark 2797907221 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() 2015-06-06 07:46:42 +10:00
victorpv d165e4d013 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)

victorpv 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.

Roger Clark 664e1c88ac 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
Roger Clark 5f9e8a04dd Added first pas at SPI::DMATransfer(byte *buf, int length) - and updated ILI9341 lib to use DMA Transfer for fill rect 2015-03-30 03:31:41 +11:00
Roger Clark e9f67b2f63 Added accessor function for the spi device to spi.h 2015-03-18 20:32:56 +11:00
Roger Clark ac742edbd7 Improved speed of SPI::write(byte) 2015-03-06 22:40:53 +11:00
Roger Clark 29ddd3beef Update SPI library properties file to fix issue caused by changing folder namne from STM32F1XX to STM32F1 2015-02-26 07:45:16 +11:00
Roger Clark 5f83c13285 renamed top level folder STM32F1XX to STM32F1 to correspond to other top level folder names e.g. STM32F3 and STM32F4 2015-02-24 20:13:04 +11:00
