Hello All, I’ve been having some issues with getting a display to work with a Particle Boron. I started with some more advanced code, but after having issues I decided to go back to the basics to see if there is just something that is being missed. This is the code that I have been flashing: #inc…

I suggest you post all your code. It depends what the SPIRead and SPIWrite were actually replaced with. Also, can you confirm you are on 0.9.0?

Hello All, I’ve made some progress today. No more red light so it seems as thought the firmware is running. I’ve been running the following code and it is printing the serial lines up until 113 then stops. Also tried drawLine and that does the same thing. Never makes it to print line 117. #include…

#define DISP_CS D15 #define SPI_DATA_CMD D16 Can you confirm your physical wiring - the hardware default for CS is A2. Try using DISP_CS A2 instead. I would also confirm SPI_DATA_CMD - DC/RS on the board - try moving this to D5 say. Have you looked at the Boron datasheet - I don't have one myse…

Hi, I appreciate your help. I’ve gone through a multitude of different configurations including the ones that you suggested. I think that there is some issue in the library that was ported that I just haven’t been able to track down. I’m seeing that it takes about 12 seconds for the Boron to start …

[image] shonky2: I’m seeing that it takes about 12 seconds for the Boron to start up from power on which would leave the display blank for that long with no feedback to the user. This is (most likely) because you have not specified SYSTEM_THREAD(ENABLE) so user code will not run until a cloud…

Hi, Thank you for pointing out SYSTEM_THREAD. I’ll check that out. https://www.newhavendisplay.com/nhd31225664ucy2-p-3537.html this is the display that is being used.

@shonky2 , looking at your code, I am perplexed as to why the D15 and D16 pins are considered valid. As @armor already pointed out, the valid pins are D0-D8 and A0-A5. The “default” hardware SPI pins are shows on the actual board (MIso, MOsi, SCK) and you can chose the CS and DATA_CMD pins within t…

[image] armor: I don’t have one myself, not sure what pin D15 and D16 are possibly A4 and A3. This is what @armor already pointed out. I'd also suggest you stick with the pin labels printed on the silk screen on the device.

@peekay123 @ScruffR Thank you all for re-stating. I apologize @armor that I dismissed it earlier. I kept referring back to the datasheet and was looking at the pin number and in my mind was connecting that to the Dpin because I had seen other code where the variables were getting defined and Dpin no…

Hi All, So I tried this and now I’m running back into the issue of the Red led single flash SOS. Not sure what would be next.
