I have a fairly ambitious project where I'm using an ESP32's VSPI channel and hope to communicate with THREE SPI devices, all at different speeds. Admittedly, I don't know enough about how well all three vendors' SPI ... WebNov 7, 2024 · Hi @FrankBoesing. there is a check for min / max I2C frequency in place in function i2cSetFrequency.I admit I don't fully understand the boundaries check, but it seems to be dependent on APB clock (which is about 80MHz for ESP32) and a minimal ratio between APB and I2C clock of 100, hence the 800kHz maximum.

Furthermore, the model 4B is currently suffering supply chain issues. On the other hand, the Rock Pi boards are available, reasonably priced and considerably faster that the model 4B.
WebJan 31, 2024 · The maximum clock frequency with GPIO Matrix is 40MHz or less, whereas using all IOMUX pins allows 80MHz. So just choose the following SPI pins to have an 80 MHz clock speed: ESP32 SPI: 80 MHz pin configuration. To drive a display only MOSI and SCLK is required from the table. So let’s use the faster pins.
WebESP32’s SDMMC host peripheral has two slots. Each slot can be used independently to connect to an SD card, SDIO device or eMMC chip. ... Currently only integer fractions of 40MHz clock can be used. For High Speed cards, 40MHz can be used. For Default Speed cards, 20MHz can be used. Note. This function is not thread safe. WebImproving Overall Speed. The following optimizations will improve the execution of nearly all code - including boot times, throughput, latency, etc: Set CONFIG_ESPTOOLPY_FLASHFREQ to 80 MHz.
