RT，当gd32h7在启用exmc驱动sdram、启用tli刷屏时，比如刷屏1024*600@rgb565，如果在启动tli之前，通过seggerRTT输出过任何内容，比如调试信息、启动信息、系统状态之类，哪怕只是无意义数据。在启动tli之后，哪怕是再也不调用任何seggerRTT相关代码，也能在seggerRTT的rtt-viewer中看到之前发送的内容被自动、重复、偶发性、周期不定、长度不定地反复发送。这个过程没有任何代码执行seggerRTT相关函数，是seggerRTT自发地。 在关掉tli后，问题消失；在出现问题后，用一个定时器比如10s后关闭tli，问题在10s后再也不出现；裸机、rtthread-nano、freeRTOS三种环境都能看到这个现象：只要启动tli开始刷屏，那么seggerRTT输出就会非常混乱。 比如，裸机代码： “ int main(void) { sys_cache_enable(); /* 使能CPU cache */ SEGGER_RTT_printf(0, "RTT TEST 0000: 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\r\n"); SEGGER_RTT_printf(0, "RTT TEST 0001:

我的一个lvgl工程从0x8000000启动,lvgl可以跑14帧,但我把lvgl工程写到0x800A000,用iap从0x800A000启动只有7帧? int main(void) { system_clock_config(); at32_board_init(); key_config(); 　if(gpio_input_data_bit_read(GPIOD, GPIO_PINS_12)==0 && gpio_input_data_bit_read(GPIOD, GPIO_PINS_13)==0){ flash_upgrade_flag(FALSE); } if(flash_upgrade_flag_read() == TRUE) { /* check app starting address whether 0x08xxxxxx */ if(((*(uint32_t*)(APP_START_ADDR + 4)) & 0xFF000000) == 0x08000000) app_load(APP_START_ADDR);//APP_START_ADDR＝0x0800A000 } 　while(1) 　}； } 以上是iap启动简化代码 int main(void) { nvic_vector_table_set(NVIC_VECTTAB_FLASH, 0xA000);//0x0800A000 nvic_priority_group_config(NVIC_PRIORITY_GROUP_4); MainState main_state = MAIN_STATE_INIT_ML307; crm_clocks_freq_type get_rcc_clock; MqttSetData data; volatile uint32_t last_mqtt_inti_time = 0; volatile uint32_t last_mqtt_pub_time = 0; volatile uint32_t last_signal_check_time=0; int ret=0; int i=0; int dir=0; char buffer[128]; uint32_t cnt=0; system_clock_config(); delay_init(); uart_print_init(115200); tmr7_int_init(239, 999); usart2_config(); gn03s_init(); lcd_struct = &lcd_dev_struct; lcd_struct->lcd_init(); tp_dev.init(); lv_init(); lv_port_disp_init(); lv_port_indev_init(); setup_ui(&guider_ui); events_init(&guider_ui); ml307r_init(); ml307r_on(); pwm_tmr3_init(); adc_dma_init(); SystemParamInit(); key_config(); // 初始化上下文 mqtt_init_param(&mqtt_param); ml307_init_context(&ml307_ctx); mqtt_init_context(&mqtt_ctx, &ml307_ctx); http_init_context(&http_ctx, &ml307_ctx); while(1) { tp_dev.scan(0); lv_task_handler(); home_ui(&mqtt_ctx,key_ret); setups_ui(&mqtt_ctx,key_ret); 　} } 以上是lvgl简化代码

[i=s] 本帖最后由 liyan123456 于 2025-4-24 19:28 编辑 [/i] 官方的例程LVGL V8.3.1 disp3 软件修改旋转无效果这是为什么呢,

前端时间在调试 GD32H7 ,可是发现使用TLI 时 还是存在问题，调了很久最后放弃了 由于H7 的架构 有多种内存块， 使用不当就存在问题 开始使用外部RAM存放显存， 一直没成功， 后来没办法使用内部RAM 单显存测试，还是不行，屏幕显示经常有马赛克， 感觉这个TLI 配置起来太麻烦了 有TLI 有2个图层 ， 使用的时候 即使用一个图层 ，2个图层还是必须要都要配置，不配置还不行 因为2个图层后面有个混合 更新输出的时候 也比较扯。 在使用LVGL 时，使用单格全屏显示缓存，我配置了TLI 的2个图层，仅使用1个图层输出， 然后再输出时使用 [color=#dadada][backcolor=#1e1e1e][font=Consolas,][color=#dcdcaa]tli_reload_config[/color][color=#b4b4b4]([/color][color=#dadada]TLI_FRAME_BLANK_RELOAD_EN[/color][color=#b4b4b4]);[/color] [/font][/backcolor][/color] 来触发TLI更新输出，但是有问题，无法显示， 这就很扯，首先也不知道什么时候更新完成？然后调用这个没有效果 有没有H7 的LGVL的例子学习一下？

void vApplicationTickHook(){ lv_tick_inc(1); } void test(void *pvParameters) { lv_ex_spinner_2(); while (1) { lv_task_handler(); } } 裸机运行正常，看一上午free的操作还是不懂，请教大神如何修改 下载视频
