WebStandard-mode, Fast-mode (Fm), Fast-mode Plus (Fm+), and High-speed mode (Hs-mode) devices are downward-compatible. This means any device may be operated at a lower bus speed. Ultra Fast-mode devices are not compatible with previous versions since the bus is unidirectional. Bidirectional bus: Standard-Mode (Sm), with a bit rate up to 100 … WebMay 31, 2024 · I had a look inside the driver and it is using a very complicated thread safe ring buffer library to store the samples. This is the architecture as far as I could understand it: 1. DMA reads ADC and writes DMA buffer using linked list config (size related to conv_num_each_intr) When the linked list is complete an interrupt is raised. 2.
