Can I use DMA for ESP32C3`IIC to drive ssd1306?
It has afterimage when I using ESP32C3`IIC to drive ssd1306 with 1 MHz. So I want to solve this problen with DMA. But in Technical Manuals, I can`t find IIC config in DMA, like this: 屏幕截图 2024-08-17 170549.png This is my code to write data: static esp_err_t ssd1306_write_data(void *sensor, const uin...

Re: printf格式化问题，编译结果和ide的语法高亮不一致（整型和长整型的认定）
