[35p32fan]

Hi,
like to have output on the display of a esp32-2432s028r 2,8" Touch TFT 240x320

somebody here can tell me how
example code I found did not get compiled

thanks

@bidrohini

thanks for your help!

using: Debian 12 on x86_64

here is what I tryed

$ sudo apt install python3-virtualenv
$ rustup toolchain install nightly --component rust-src
$ cargo install cargo-generate
$ cargo install ldproxy
$ cargo install espflash
$ cargo install cargo-espflash


$ cargo generate --git https://github.com/esp-rs/esp-idf-template cargo
$ cd espdisplay
$ cargo add ili9341
$ cargo add embedded-graphics

$ espup install
$ . ~/export-esp.sh
$ caro clean
$ rm -rf .embuild
$ cargo build
