Hi, ive been working on this spotify remote project for awhile and finally coming towards a close (I'm excited) and my serial monitor output has been fine the whole time but last night I connected my lcd for the fist time, ever since I did this my serial output stopped working. I have every single Dx pin filled, I havnt touched the serial pins yet, anyone have advice?
can you give details of the LCD and how it is connected?
upload a schematic showing the wiring and how the system is powered
does the LCD work by itself?
its an st7735 128*160 lcd and all the code for displaying the lcd work, its connected through spi but i cant remember what pins i connected the rst dc and cs pins too as im at work rn and cant check, i also have 2 other spi devices an sd card reader (lcd built in) and an nfc reader, the mfrc522 i think it is, everything works as intended but the serial monitor, Serial.println("loop"); wont print, im using api calls and used to get data out all the time but now i don't, also is there a way to get the lcd screen to update and now flash when it updates?
system is powered through usb and an external 3.3v power supply to the 3.3v pins
which Wemos D1 mini are you using ? give a link ?
I assume the SPI devices are using seperate CS or SS prins and you are not using GPIO1 and GPIO3 (used by USB for flashing and debugging)
upload a schematic showing the wiring and how the system is powered??
