marlinfirmware / u8glib-hal Goto Github PK

Could someone please add to the README.md page a description of exactly what use-cases this library is for, and whether it is required or optional for those cases? The blurb on https://github.com/MarlinFirmware says "Customized U8glib for use in Marlin 2.0"... which leads one to believe that it might be required for Marlin 2.0. But then the README says "AVR, Arduino & Due access to the library is not changed." Does that mean that the actual library functions are the same as regular U8glib, which might already be installed in the Arduino libraries? Or should this U8glib-HAL always be used for Marlin 2.0, in which case how to install it?
Also, what is "non-native". If that means "compiling in an environment other than Arduino", please spell that out. Thanks.

Don't know if this repo si still active I would like to know if it may be tollarated to change WIDTH define with LCD_WIDTH.

Related to MarlinFirmware/Marlin#14904

I may post a PR if it's ok

Add a library.properties file into this repository so Arduino IDE users can just drop this version of the library into their Arduino/libraries folder to provide Marlin with the correct U8glib-hal required to compile.

Example library.properties here https://github.com/MarlinFirmware/Marlin/files/6710738/library.properties.zip

Description

It looks like #6 bricked my ability to us my Blue Pill (STM32F103CB) with an SSD1306 OLED.
(28e15cd)

By default "U8glib-HAL" is being ignored when compiling for STM32F1 but I found that it did work anyway before the Changes in #6 were made.

Steps to Reproduce

1. Get new Marlin bugfix-2.0.x code and open in VS Code
2. Make the following changes in "platformio.ini"

• under [platformio]

  • env_default = STM32F1

• under: [env:STM32F1]

  • change "lib_ignore = U8glib-HAL" to "lib_ignore = ;U8glib-HAL"
  • change "board = genericSTM32F103RE" to "board = genericSTM32F103CB"

3. Make the following changes in "Configuration.h"

• "#define SERIAL_PORT 0" to "#define SERIAL_PORT 1"
• "#define MOTHERBOARD BOARD_RAMPS_14_EFB" to "#define MOTHERBOARD BOARD_MORPHEUS"
• "//#define U8GLIB_SSD1306" to "#define U8GLIB_SSD1306"

Expected behavior:

I expected the Code to Compile.

Actual behavior:

It didn't :)

####HOTFIX

Since an older Version did compile, I was able to find where the error comes from. Here is how to get it working:

1. Coplete: "### Steps to Reproduce"
2. Get U8glib-HAL code from: November 2018: https://github.com/MarlinFirmware/U8glib-HAL/tree/99e44fa4903174ce8660860ee166504e13d0483a
3. Replace "src" and "library.json" in "...\Marlin-bugfix-2.0.x.piolibdeps\U8glib-HAL_ID1932" with files from Nov 2018
4. Restart VS Code

Additional Information

I am not sure why #6 causes these weird errors.

how to use this library in arduino for stm32g474re?

Hello,

It seems the U8glib-HAL library for Marlin bugfix disappeared.

Compiling Marlin (VSCode + PIO) gives this error :

FDUnrecognizedStatusCode: Got an unrecognized status code '404' when downloaded https://github.com/MarlinFirmware/U8glib-HAL/archive/bugfix.zip

typing "https://github.com/MarlinFirmware/U8glib-HAL/archive/bugfix.zip" in a browser also gives a 404 error (and by the way this link is a broken link)

As a result, U8glib-HAL is not installed.

Never had this issue before... Was a "archive" or "bugfix" branch recently removed from this repo ?

Hi, so the REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is working fine, except the menu is erratic, sometime it will move to next item, sometimes it won't, sometimes it will jump four or five spaces after not doing anything.

Push click ok, display ok, just the scrolling issue

SKR v1.3, Marlin 2

Using stock CR10 LCD in ReARM+ramps1.4 (sl1pkn07/Marlin@8351042)

In the u8g_com_stm32duino_hw_spi_fn() function in u8g_com_stm32duino_hw_spi.cpp the SPISettings is initialized with SPI_CLOCK_DIV2 instead of a clock speed:

    case U8G_COM_MSG_INIT:
      u8g_SetPIOutput(u8g, U8G_PI_CS);
      u8g_SetPIOutput(u8g, U8G_PI_A0);
      u8g_SetPIOutput(u8g, U8G_PI_RESET);

      u8g_SetPILevel(u8g, U8G_PI_CS, 1);
      
      spiConfig = SPISettings(SPI_CLOCK_DIV2, MSBFIRST, SPI_MODE0);
      SPI.begin();
      break;

SPI_CLOCK_DIV2 is defined as:

// Compatibility with sketches designed for AVR @ 16 MHz could not
// be ensured as SPI frequency depends of system clock configuration.
// user have to use appropriate divider for the SPI clock
// This function should not be used in new project.
// Use SPISettings with SPI.beginTransaction() to configure SPI parameters.
#define SPI_CLOCK_DIV2   2
#define SPI_CLOCK_DIV4   4
#define SPI_CLOCK_DIV8   8
#define SPI_CLOCK_DIV16  16
#define SPI_CLOCK_DIV32  32
#define SPI_CLOCK_DIV64  64
#define SPI_CLOCK_DIV128 128

in the core. The SPI_CLOCK_x constant was intended to be used with the obsolete SPI.setClockDivider(divider) function.

I'm not 100% sure but I think the SPISettings should be initialized with a speed of 2500000 (works fine with the FYSETC MINI 12864).

Visual Code informs this library was updated 22 hours ago from 0.52 to 0.53 but the libaray is broken for all STM compiles I try, forcing a roll back to 0.52 resolves the issue:

The error is below:

It can also be seen as missing in .pio/libdeps/{env}/U8glib-HAL/src/clib/u8g.h
which I cannot explain, its there if I download the library manually from github
