SDCFile

Readme This is a C language project that demonstrates the serial peripheral interface (SPI). This project interfaces the ST7735R LCD and SDC to the microcontroller. main0 Low level test, it will leave the SDC unformated. main1 Simple file write and test, SDC needs FAT16 format. main2 Longer file write and test, SDC needs FAT16 format. main3 Will create a large binary file called Sound.bin. main4 Will stream Sound.bin to 12-bit DAC at 11.025 kHz. First run main3 to create Sound.bin. Then, connect PB20 (TExaS scope) to PA15 (DAC output) and run main4. Derived from Texas Instrument code spi_controller_multibyte_fifo_poll_LP_MSPM0G3507_nortos_ticlang spi_controller_command_data_control_LP_MSPM0G3507_nortos_ticlang spi_peripheral_register_format_LP_MSPM0G3507_nortos_ticlang

Hardware Required MSPM0G3507 LaunchPad™ Development Kit (LP-MSPM0G3507) We have tested 2 verions of the 160by128 pixel ST7735R with SDC Adafruit ST7735R Product ID: 358 HiLetgo ST7735 TFT and SDC Pin assignments The following shows the wiring for the Adafruit ST7735R. See the source code in ST7735.c for wiring other displays. SPI1 SCLK: PB9 is ST7735R LCD clock CLK SPI1 PICO: PB8 is ST7735R LCD data MOSI SPI1 POCI: PB7 is SDC data MISO GPIO Output: PB6 is ST7735R LCD chip select TFT_CS GPIO Output: PB15 is ST7735R LCD !RST GPIO Output: PA13 is ST7735R LCD RS GPIO Output: PA12 is SDC chip select CARD_CS Analog Output: PA15 is 12-bit DAC output Analog Input: PB20 is ADC input used by TExaS scope Output: PA0 is red LED1, index 0 in IOMUX PINCM table Output: PB22 is blue LED2, index 49 in IOMUX PINCM table Output: PB26 is red LED2, index 56 in IOMUX PINCM table Output: PB27 is green LED2, index 57 in IOMUX PINCM table Input: PA18 is S2 positive logic switch, index 39 in IOMUX PINCM table Input: PB21 is S3 negative logic switch, index 48 in IOMUX PINCM table LaunchPad Jumpers Remove J16 J17 J18: Disconnects light sensor from the microcontroller PA22 PA27 PA26 J4: Connects PA0 to red LED J5: Connects PB22 to blue LED2 J6: Connects PB26 to red LED2 J7: Connects PB27 to green LED2
