• Assemble the shell

    MakerM0 • 02/17/2023 at 07:23 • 0 comments

    I took the time to print the shell using a 3D printer, then sanded and painted it.

    It looks pretty good.

    If you use CNC, the effect will be better


  • add stopwatch function

    MakerM0 • 02/09/2023 at 08:39 • 0 comments

     The display of the stopwatch is controlled according to different keys;

  • Add shutter function

    Split GIF image in frames (ezgif.com)

    I use this website to convert gif files to multiple jpg files and then to .c files, use TMOS to update a picture every 100ms, and perform animations when the keys are pressed.

#include "img_shutter.h"

#include "hidconsumer.h"

#define IMG_NUM (img_shutter_96_height/img_shutter_96_width)

static uint8_t img_cnt = 0;
static uint16_t img_color;

static void init(void *data) {

  • Assemble the circuit

    MakerM0 • 01/28/2023 at 09:02 • 0 comments

    After a long time, finally there was time to continue the project, and I welded a complete set of boards.

    This is the schematic of CH582f board.

    Power on, firmware can be downloaded normally.

  • Test the 0.85 Inch Display

    MakerM0 • 12/05/2022 at 08:19 • 0 comments

    I have a 0.85-inch IPS display, GC9107, its resolution is 128X128, support SPI interface, for this I drew a PCB.

    After a period of waiting and debugging, I successfully used CH582M to light up the 0.85-inch display, and ported the µGUI.

    • MOSI------------PA14
    • SCLK------------PA13
    • CS---------------PA15
    • DC---------------PB4
    • BL----------------PB7
    • RST--------------PB15
