Noob Issue: Cant manage to get this building for the stm32f1xx_hal #168

Closed zacck closed 1 year ago

zacck commented 1 year ago

Description of the problem/feature request/other

My issue at the moment is that I can't get my source code to even build I run into a linker error when I try and declare the interface

My code

//! Print "Hello world!" with "Hello rust!" underneath. Uses the `embedded_graphics` crate to draw
//! the text with a 6x8 pixel font.
//!
//! This example is for the STM32F103 "Blue Pill" board using I2C1.
//!
//! Wiring connections are as follows for a CRIUS-branded display:
//!
//! ```
//!      Display -> Blue Pill
//! (black)  GND -> GND
//! (red)    +5V -> VCC
//! (yellow) SDA -> PB9
//! (green)  SCL -> PB8
//! ```
//!
//! Run on a Blue Pill with `cargo run --example text_i2c`.

thank you so much for your time!

You most likely need to run with --release - debug builds are often too large to fit in flash memory which is what the linker error is describing.

blaa commented 1 year ago

Yes. I've just set this up with stm32f1xx_hal and --release is required pretty much all the time. Without using write!, semihosting, etc. it's possible to get this to fit without --release.

With --release I'm at 13.7k which leaves plenty of space still.

jamwaffles commented 1 year ago

Great! Glad to hear it's working :)

blaa commented 1 year ago

Just need to add that I in fact have sh1106 oled - that almost (which is a bit confusing) works with ssd1306. Text was a bit shifted, but otherwise would be usable. I was starting to try to fix memory offsets when I found some info that it might be a different chipset.

If you have a FAQ section somewhere it might be worth noting there (?).

Still this issue is certainly worth closing. ;)

jamwaffles commented 1 year ago

Ah, in that case you might want to try the sh1106 driver which should work better with that IC.

blaa commented 1 year ago

Yeah, I did, works much better. Thanks for your work! My first time with embedded Rust and it seems great so far.

Cheers,
