    SPI doesn't seem to be working properly

    Which MCU?

    Update multiple time for work

    Three suggestions: Try adding a delay() after Serial.begin(). Try slower speeds. Try another USB cable and port.

    Arduino Library to Energia

    Read the FAQ.
  6. @poulichp I confirm: Optional step - Format the image to 32-bit PNG with https://www.imagemagick.org/script/index.php Step 1 - Use the utility https://github.com/vaskevich/png2c to convert the PNG file into a C-array. Step 2 - Use the example LCD_screen_Logos from the EduBPMKII_Screen and adapt it to match the size of the image and the Kentec 3.5" SPI display. Image Screen
  7. The utility generates an 8-bit-coded C-array, not the 16-bit-coded C-array expected by the Kentec_35_SPI library. Have you tried the utilities I mentioned earlier?
  8. If the size of the image is 80x80 pixels, you need to process it accordingly and target an area of 80x80 pixels, as the Kentec 3.5" display is 320x240. The grLib library and the Kentec_35_SPI library for Energia may have different ways of dealing with images. Please have a look at the examples provided for the Educational BoosterPack, especially LCD_screen_Logos, for Energia. Among many other options: Offline https://github.com/vaskevich/png2c Online https://littlevgl.com/image-to-c-array The link provided http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/Graphics_Library/latest/index_FDS.html results in a 404 error.
  9. For SPI doesn't work as expected on MSP432 RED, see https://github.com/energia/msp432r-core/issues/9
  10. See Ultra-Low Power with MSP430 at https://embeddedcomputing.weebly.com/ultra-low-power-with-msp430.html

    HDC1080 with MSP430G2553

    The issue has been reported and solved. Three hints: First hint: The MSP430G2553 has two I²C ports. Try both of them. Second hint: https://github.com/energia/msp430-lg-core/issues/62 Third hint: https://forum.43oh.com/topic/13153-cant-get-bme280-to-work-with-msp430g2554/
