Back-light (HIGH or LOW)I notice that if I perform a SPI loopback test (by connecting MOSI and MISO directly and printing the result of SPI.transfer(...) to the serial monitor), no data is read from pin GP4, as per the #define. The actual MISO pin used by the Pi Pico is GP16 (I figured this out by probing all the possible SPI0RX pins). If I connect MOSI (on GP19) to MISO (on GP16, instead of GP4), the loopback test is successful.Why is the active MISO changed from what is defined in Setup23_TTGO_TM.h? You must be logged in to vote 5 replies This all comes down to choice of pins I think. The SPI default is GPIO 16 and GPIO 19. See here: is probably best to pick up the SPI class inatance direct from the TFT_eSPI library as otherwise the TFT_eSPI library may be working with a different set of pins to the default and cause problems. I happen to be using default pins so do not see the problem.Try this sketch: // We only use SPI interface for this exampleSPIClass& spix = SPI; // Create a class variable to hold the SPI class instance (default instance is SPI port 0 pins only)#include // Hardware-specific libraryTFT_eSPI tft = TFT_eSPI(); // Invoke custom libraryvoid setup() { tft.init(); // Initialise library (will also get SPI class instance) spix = tft.getSPIinstance(); // Set to instance used by TFT library (may be SPI port 0 or 1) tft.setRotation(3); // Show speed of fillScreen tft.fillScreen(TFT_RED); tft.fillScreen(TFT_GREEN);

Chosen SigmaDSP the SPI SCLK frequency can be set as high as 20 MHz. It requires four pins on your microcontroller, preferably a hardware SPI port; software SPI implementations are possible but will typically incur high overhead on a microcontroller.I2C is a slower protocol. Most SigmaDSP processors support a maximum SCL frequency of 400 kHz, although ADAU146x processors are specified up to 1 MHz. I2C requires two pins on your microcontroller, preferably a hardware I2C port; software I2C implementations also incur some microcontroller overhead.There are many other reasons why either I2C or SPI might be more suitable in your device. For simplicity we won't go into those reasons here. If you are not sure which to use, go ahead and post a question in the EngineerZone support forum. If you describe your application we can guide you through your choice.In the example code you can switch between I2C and SPI code by toggling #define USE_SPI in USER_SETTINGS.h. To save memory, code for the unused interface will be excluded by the compiler.Hardware ConnectionsLogic levels on your microcontoller must be the same as the IOVDD supply of your SigmaDSP, or level shifters should be used. The Arduino Uno uses 5V logic by default which is not directly compatible with SigmaDSP processors.It is recommended to connect your microcontroller to a working SigmaDSP evaluation board before attempting to program a custom board and verify working communications between the microcontroller and DSP. This allows you to separate the firmware debug process from the hardware debug

Device that decides when to trigger communication and which slave is the recipient of the message. SPI master devices are generally used in high-speed communication and the focus is to exchange data with other devices acting as slaves (e.g., sensors, memories, or other microcontrollers). This use case presents how to configure the SPI as a master device along with its pins to send data to two slave devices, one at a time. To achieve the functionality described by the use case, the following actions will have to be performed: System clock initialization SPI1 initialization Peripheral Pin Selection (PPS) initialization Port initialization Slave control functions Data exchange function 1.3.3.1 MCC Generated Code To generate this project using MPLAB® Code Configurator (MCC), follow the next steps: Create a new MPLAB X IDE project for PIC18F47Q10. Open the MCC from the toolbar. Information about how to install the MCC plug-in can be found here. Go to Project Resources → System → System Module and do the following configuration: Oscillator Select: HFINTOSC HF Internal Clock: 64_MHz Clock Divider: 1 In the Watchdog Timer Enable field in the WWDT tab, make sure WDT Disabled is selected. In the Programming tab, make sure Low-Voltage Programming Enable is checked.
