Problem with PCF8812 #2421

bnv12345 · 2024-04-09T17:38:18Z

Hello. I'm trying to start a display from Siemens C55 (PCF8812). The display only worked when I replaced it in the file u8x8_d_pcf8812.c Initialization sequence.

_static const uint8_t u8x8_d_pcf8812_96x65_init_seq[] = {

U8X8_START_TRANSFER(), /* enable chip, delay is part of the transfer start /
U8X8_C(0x21), // PowerON, ExtCommandSet
U8X8_C(0x09), // Internal HV-gen x3
U8X8_C(0xB7), // Set Vop
U8X8_C(0x16), // Bias n=2 //15
U8X8_C(0x06), // Temperature coeff 2
U8X8_C(0x20), // StandartCommandSet
U8X8_C(0x0C), // normal mode, display non-inverted
U8X8_END_TRANSFER(), / disable chip /
U8X8_END() / end of sequence */
};_

I found this information on the Internet. Long-standing problem. The resolution is not yet specified correctly. It was also in the first version of this library.
Also changed the screen resolution-

_static const u8x8_display_info_t u8x8_pcf8812_96x65_display_info =
{
/* chip_enable_level = / 0,
/ chip_disable_level = */ 1,

/* post_chip_enable_wait_ns = / 100,
/ pre_chip_disable_wait_ns = / 100,
/ reset_pulse_width_ms = / 100,
/ post_reset_wait_ms = / 100,
/ sda_setup_time_ns = / 100,
/ sck_pulse_width_ns = / 100,
/ sck_clock_hz = / 4000000UL, / since Arduino 1.6.0, the SPI bus speed in Hz. Should be 1000000000/sck_pulse_width_ns /
/ spi_mode = / 0, / active high, rising edge /
/ i2c_bus_clock_100kHz = / 4,
/ data_setup_time_ns = / 40,
/ write_pulse_width_ns = / 150,
/ tile_width = / 12,
/ tile_height = / 9,
/ default_x_offset = / 0,
/ flipmode_x_offset = / 0,
/ pixel_width = / 101, // 96
/ pixel_height = */ 64
};_

Everything worked, but the five right columns are trash.

If I reduce this parameter (/* tile_width = */ 12) to 11, then there is more trash.

If you put (/* tile_width = */ 13) or more - the Arduino constantly reboots. Please, help.

Increasing the tile size will cause memory issues and indeed might lead to a reboot.

What is the actual pixel width of your display?

bnv12345 · 2024-04-14T16:00:55Z

This is a display from Siemens C55. Actual pixel size is 101*64

I have created a new constructor "U8G2_PCF8812_101X64".
Can you do a test, whether this works better?
The code is available in the latest beta release 2.35.17

You can download the latest U8g2 beta release from here: https://github.com/olikraus/U8g2_Arduino/archive/master.zip
Arduino IDE:

Remove the existing U8g2_Arduino library (https://stackoverflow.com/questions/16752806/how-do-i-remove-a-library-from-the-arduino-environment)
Install the U8g2_Arduino Zip file via Arduino IDE, add zip library menu (https://www.arduino.cc/en/Guide/Libraries).

PlatformIO:
platformio.ini (https://docs.platformio.org/en/latest/projectconf/section_env_library.html#lib-deps) should include

bnv12345 · 2024-04-16T10:28:04Z

The new library did not work because the display initialization was not changed. In the file u8x8_d_pcf8812.c you need to put

static const uint8_t u8x8_d_pcf8812_96x65_init_seq[] = {
  U8X8_START_TRANSFER(),             	/* enable chip, delay is part of the transfer start */
  U8X8_C(0x21), // PowerON, ExtCommandSet
  U8X8_C(0x09), // Internal HV-gen x3
  U8X8_C(0xB7), // Set Vop
  U8X8_C(0x16), // Bias n=2    //15
  U8X8_C(0x06), // Temperature coeff 2
  U8X8_C(0x20), // StandartCommandSet
  U8X8_C(0x0C), // normal mode, display non-inverted
  U8X8_END_TRANSFER(),             	/* disable chip */
  U8X8_END()             			/* end of sequence */
};

I wrote this in my first message. After the replacement this code everything worked great. There is no garbage.

Thanks for testing. I have added the missing init code in beta release 2.35.18

Unfortunately, this option without editing did not work either. I edited the u8x8_d_pcf8812.c file a little and everything worked again.
Added a function - static uint8_t u8x8_d_pcf8812_101x64_generic(u8x8_t *u8x8, uint8_t msg, uint8_t arg_int, void *arg_ptr)
And the last line of this file
return u8x8_d_pcf8812_96x65_generic(u8x8, msg, arg_int, arg_ptr); replaced with
return u8x8_d_pcf8812_101x64_generic(u8x8, msg, arg_int, arg_ptr);
