cepics

yes!!

cepics

in SD.h I changed:

    bool begin(uint8_t ssPin=SS, SPIClass &spi=SPI, uint32_t frequency=4000000, const char * mountpoint="/sd", uint8_t max_files=5, bool format_if_empty=false);

to

    bool begin(uint8_t ssPin=SS, SPIClass &spi=SPI, uint32_t frequency=1000000, const char * mountpoint="/sd", uint8_t max_files=5, bool format_if_empty=false);

and in sd_diskio.cpp:

    if (card->frequency > 25000000) {
        card->frequency = 25000000;
    }

to

    if (card->frequency > 10000000) {
        card->frequency = 10000000;
    }

.... and now seems to work!!

cepics

I trierd to modify the sd.begin() function in the used SD.h with the new frequency .... but no joy!!

still searching......

any ideas??

all the libraries are up to date....

I could upload the code with M5burner, but I need to modify the clock of the sd card in M5Stack.cpp from 40Mhz to 10Mhz to work with M5stack basic....

some tips?

tnks a lot

cepics

the first sketch works, with M5Stack basic, if I modify the M5Stack.cpp library from:

// TF Card
if (SDEnable == true) {
    SD.begin(TFCARD_CS_PIN, SPI, 40000000);
}

to

// TF Card
if (SDEnable == true) {
    SD.begin(TFCARD_CS_PIN, SPI, 10000000);
}

cepics

tnks a lot to answer!!!

but I can't find where the M5Stack.cpp file is invoked....

mumble mumble...

hi all
I'm trying to use M5Stack-SD-Updater on M5stack basic (V2.61), but after flashing the M5Stack doesn't see the sd card....
same process on M5Stack gray (v 2.4) works...

same behavior if I use M5Burner to burn lovyan launcher on the two controllers... with the same sd card, M5gray can access to sd and M5basic don't

I tried four different M5Stack basic unit ... same behavior!!

ideas?
tnks a lot!!!

cepics

Hi all, I have problems with lovyan launcher... now the app doesn,t open the sd of the stack basic..

when I burn lovyan launcher with M5burner in a M5stack basic, the sd fail... same proces on a M5Stack gray, works...

on a basic unit, with this sketch, sd fail!!

Hi all,
I'm trying to use the unit fader with an old M5Stick gray

but analog read on pin 13 or 25 seems to be impossible during WIFI operation.....

can I assign pin 13 or 25 to ADC1??

@macsbug said in ATOM Lite Display not display in smallHd 503:

1920/2,1080/2,24

No way to display something on the 503.... I tried all configuration:

// M5AtomDisplay display(); // 1280 x 720
M5AtomDisplay display(1920,1080,24); // 1920 x 1080 , 24bit
// M5AtomDisplay display(1366,768); // 1366 x 768
// M5AtomDisplay display(1920/2,1080/2,24);
// ( 480, 1920);(1920, 480);(1280, 720);(1024, 768);
// ( 960, 540);( 800, 600);( 640, 480);( 640, 400);
// ( 640, 360);( 512, 212);( 256, 192);( 320, 240);

when I connect hdmi cable to the 503, the monitor "feel" something (green led on and image settings in the "in settings page" of 503) but no image displayed.....

the same cable works in other setup....

Hi all,
someone with a working arduino code for M5UnitOLED using U8g2 Library?

Using this constructor, I can display things but it is a little triky to calcolate positions, rotates and mirror...

@m5stack said in Change I2C pin in M5GFX Library (to use With ATOM LITE):

if you wanna change the I2C pin. you could use this code.
#include <M5UnitOLED.h>

//M5UnitOLED display; // default setting

M5UnitOLED display ( 21, 22, 400000 ); // SDA, SCL, FREQ
