I already tried but without any results, i have a ST7789V, with the TFT_SPI library it works well but not with the M5Stack library....

Hi casascius,
In fact I have a code where we call on the TFT_eSPI library and the M5Stack library which draw measurement instruments, here is an extract:

#include <m5stack.h>
#include <gaugewidgets.h>
#include <free_fonts.h>

It works with an IL9341 but not the others, I modified the TFT_eSPI library but without result ...

Good evening everyone,
Can we modify the M5Stack (Arduino) library to operate an LCD type ST7789V or other LCD in place of the Ili9341 or the Ili9342C ?

If so would you have an example?

Fred

I don't understand anymore, now it works but I changed the Libraie the same but obviously more complete.
I hope it will work in time ...
Thank you Felix

I don't know like Debog ESP32 + MCP2515 with Arduino.
On the other hand, is there any other pines for SPI ?

I have this:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00

Felix can you see my code ?

If I deactive
//M5.begin();
//M5.Lcd.setTextColor(WHITE);
it works, strange.

Hello Felix Thank you for advancing, yes I know I was wrong by writing the effective position9341 CS = 15 and MCP2515 CS = 5.
For the CS of the MCP2515 I tried from others GPIO E it returned to conflict with the M5Stack library ...

Hello everyone,
I have an ESP32 WROOM 32 with a TFT ILI9341 SPI and a CAN MCP2515 SPI, but I can't operate the CAN if the command m5.begin (); is active in the code, if it is //m5.begin (); The CAN works.
My question is how to make the TFT Ili9341 spi with the CAN MCP2515 cohabit?

Ili9341:
Miso (not connected) otherwise GPIO19
Mosi ===> GPIO23
CS =====> GPIO15
DC =====> GPIO2
Reset ===> GPIO4
SCLK ===> GPIO18

MCP2515:
Miso ===> GPIO19
Mosi ===> GPIO23
CS =====> GPIO5
SCLK ===> GPIO18

I tried everything but without success it looks like the M5Stack library is incompatible and blocks the CAN.
Can you help me ?

Regards,
Alfred from France, sorry for my english....
