  1. Hi All, Many thanks for your earlier help! I would like to use a larger PNLC display, such as the 400x240 (LC027B7DH01). Does anyone know if I can use the BOOSTXL-SHARP128 module to drive this larger display? If so, what changes do I need to make to the library? Thanks in advance.
  2. Thanks. I think I have it working now. Will share on this forum as soon as I have run some tests. Cheers!
  3. Hi all, I have recently acquired a color click board (https://www.digikey.co.uk/en/product-highlight/m/mikroelektronika/color-click-board) and would like to get it working with one of my MSP430 Launchpads. A sketch already exists for the Arduino (https://github.com/raivisr/TCS3471-Arduino-Library/blob/master/TCS3471/examples/ColorSensor/ColorSensor.pde) I have tried porting it over to MSP430, but have been unsuccessful. Do you have any suggestions as to where I may be going wrong? Problems are with undefined references. Thanks!
  4. I also have the same problem. Using MSP-EXP430G2553 & HC-05. I too can send data from my mobile, but can't receive anything. Using Energia (same code as kellyshen)
  5. I've commented out all of the display stuff and disconnected the BOOSTXL-SHARP128. I'm not sure why it was drawing so much current with the BOOSTXL and myScreen functions?
  6. Thanks for your reply. Regarding burden voltage, I have tried switching to mA range and read 0.14 mA, so I don't think that's the problem. I read the same current (140 uA or 0.14 mA, depending on DMM range) when the BOOSTXL-SHARP128 is not physically connected to the Launchpad. The current goes down to sub-uA when I comment out all of the myScreen functions.
  7. Hi, I’m trying to get my MSP-EXP430FR5969 (or preferably MSP-EXP430F5529) to work with BOOSTXL-SHARP128 at a few uA when it is not selected or being written to, i.e. when it’s idle. My MSP430s consume only a fraction of a uA in lowest power mode, but as soon as I add myScreen.begin() to setup(), it all goes crazy. In my sketch (below), I have set all ports as outputs to ensure there are no floating inputs. This reduces current consumption from several hundred uA to ~160 uA. I then connected my BOOSTXL-SHARP128 to my MSP-EXP430FR5969 via jumper wires to LCD_DISP, LCD_CD, SPI_CLK, SPI_MOSI, and gnd. This is enough to enable me to write to the display (ignore the green LED - I disabled this later). I tied MISO to gnd, since it is an input and isn’t used – this reduces the current consumption further to ~140 uA. I’m guessing P1_7 was re-initialised somewhere in one of the function calls to be an input, even though I initialised it as an output in setup()? Interestingly, my code doesn’t write anything to the display when the module is plugged directly onto the MSP430, and the current consumption also shoots up to a couple of mA! Am I correct in thinking that even after I have initialised the ports as outputs (using PnDIR) and set the outputs to HIGH (using PnOUT), sketch functions can still use those ports as outputs, i.e. the output ports can still be switched between HIGH and LOW by code in loop()? I was expecting to get the current consumption (measured on J9) down to just a few microamps. Is there anything I’m missing? Thanks in advance for your help (and for responses to previous questions!)

  8. Hi, I've tried this also, but I get the following error message:
  9. Hi All, I've been trying to get my BOOSTXL-SHARP128 to work. I've done loads of searches, but I can't find a solution. Does anyone know how to get the module to display a simple "Hello!" type message using Energia? Please see my code - below. It just seems to display lots of lines and dots. Any ideas what I'm doing wrong? Any help would be much appreciated.
