esp-32-camera在esp-idf 4.2下编译错误

Postby edgeAI4cv » Thu Jun 17, 2021 12:27 am

编译环境为vs code+esp-idf extension v4.2, 按照git上要求把esp32-camera库拷到项目的components下;esp-idf build时报错:

../components/esp32-camera/target/esp32/ll_cam.c:199:5: error: implicit declaration of function 'esp_rom_delay_us'; did you mean 'ets_delay_us'? [-Werror=implicit-function-declaration]
esp_rom_delay_us(1);

发现是target文件夹中ll_cam.c中:

#if ESP_IDF_VERSION_MAJOR >= 4
#include "hal/gpio_ll.h"
#else
#include "rom/ets_sys.h"
#include "soc/gpio_periph.h"
#define esp_rom_delay_us ets_delay_us
static inline int gpio_ll_get_level(gpio_dev_t *hw, int gpio_num)
{
if (gpio_num < 32) {
return (hw->in >> gpio_num) & 0x1;
} else {
return (hw->in1.data >> (gpio_num - 32)) & 0x1;
}
}
#endif

这部分以及下面一个函数定义里:
esp_rom_delay_us(1);
引起的,不知道是esp-idf版本问题还是配置问题,清指教;

esp32-camera 基于 v4.3 做了些修改,你可以使用 IDF v4.3。
或者你直接修改下 ll_cam.c,在 #include "hal/gpio_ll.h" 之后加上 #define esp_rom_delay_us ets_delay_us。

感谢及时回复!

你提到的在esp-idf 4.2上打补丁的办法我前2天试过,运行你们的demo时第一次截图可以成功,但第二次就会报错:

I (1001) ov2640: Set PLL: clk_2x: 0, clk_div: 0, pclk_auto: 0, pclk_div: 8
I (1081) example:take_picture: Taking picture...
I (1181) example:take_picture: Picture taken! Its size was: 12268 bytes
I (16181) example:take_picture: Taking picture...
W (20181) cam_hal: NO-EOI
W (21871) cam_hal: NO-EOI

刚才我删除了4.2,安装了4.3,不作任何修改编译顺利完成,但刷到板子上还是报上面的同样错误;不知道问题在哪里?

另外,前几天我用platformio平台编译过这个demo,运行结果记得是正常的,每次都能截到正确图片;我现在想直接采用esp-idf平台。

第一个关于 delay 函数的问题已经修复,第二个问题看起来是找不到jpg标记头。可能是xclk配置得过高?
目前 camera 驱动还在更新中,不是很稳定,请更新最新的 [esp32-camera](https://github.com/espressif/esp32-camera) 再尝试一下。

我更新了esp32-camera,编译后运行程序报错变成另外错误,截图一次成功后,下一次报错如下,再程序自动重启,第一次截图成功,第二次报错,重启......

请问这个问题可以解决吗?或者哪个esp-idf的版本对应esp32-camera的哪个版本可以正常运行这个demo程序?

比较奇怪的是在platformio框架下可以正常执行,而它用的很陈旧的idf版本;

你先用 esp32-camera 的这个 commit:a5ccbec,结合 idf v4.3 也是可以的。

上面那个commit经实验跑这个demo没问题!多谢!

用的idf是4.2.2版;
