spi_st7735 line 27

Hi,

sorry when I'm wrong.

First we declare 3 outputs: gpio_set_function(TPicoPin.SPI_CS, TGPIOFunction.GPIO_FUNC_SPI); gpio_set_function(TPicoPin.SPI_SCK, TGPIOFunction.GPIO_FUNC_SPI); gpio_set_function(TPicoPin.SPI_TX, TGPIOFunction.GPIO_FUNC_SPI);

These are CS = gpio17 pin22 SCK = gpio18 pin24 TX = gpio19 pin25

LINE 27 st7735.Initialize(spi,TPicoPin.GP16,TPicoPin.GP14,st7735.ScreenSize128x128x16);

What are GP16 and GP14 ?

Kind regards. Marcel

Hi,

[image: IMG_20231102_114243.jpg] [image: pcb 03.jpg] PCB is my own DIY.

Next ting is to dive into the CustomDisplay-unit! Also got uart Tx working. Rx, I have to do next.

Kind regards. Marcel

Hi, Michael!

just ran into this issue:

line 38 in https://github.com/cobaltBlueCloud/pico-fpcexamples/blob/main/uart_irq_demo/uart_irq.lpr

shows: received_string+=caractere;

should this be received_string:= received_string + caractere ?

Kind regards. Marcel
