WebJul 31, 2024 · SDIO also tends to be able to be clocked faster than SPI. Of course, your speeds will vary depending on what microcontroller you hook it up to. When we used SDIO instead of SPI on CircuitPython with the SAMD51 Grand Central, we got a speed increase of about 200% when reading data off the card WebSep 30, 2024 · You should have known that 128Mbit of data storage would be too tight. Your heart is racing. NOR Flash memory with higher capacities are not available in the same 8-pin package. And the cost is much higher. As a PCB redesign seems inevitable, NAND Flash furtively appears as a cheaper alternative. WebJul 25, 2014 · A quick flash question: Is there any difference between the QSPI Flash and an SD-Card from the perspective of the Cyclone V HPS? (Apart from the obvious ones, the SD-Card being removable and usually bigger). Does the HPS treat the SD-Card equally to the QSPI Flash or is there any difference? justice robert berliner democrat
