Re: How sharing SPI for ethernet w5500, lora sx1276 and sdcard

Hello ESP_Sprit, I followed your recommendations and everything went well in the initialization of SDSPI_SDMMC, however, both the LORA and the W5500 showed totally strange behavior, and I found a little problem that I believe is related to your driver, in the case of LORA and SDCARD, I used the spi_...

Re: How sharing SPI for ethernet w5500, lora sx1276 and sdcard

Good night ESP_Sprite, I was able to successfully share the SPI for the W5500 and LORA, with the drive initialization at 20MHz and using the spi_bus_add_device() function, but I'm trying to integrate the SDCARD example that I'll leave the link below, and there's no example in it where I can configur...

Re: How sharing SPI for ethernet w5500, lora sx1276 and sdcard

Thanks for the reply, ESP Sprite. Just to finish my doubt, when I call the spi_bus_add_device() function, will I be adding the devices to the VSPI bus correct? as in the code used below! ESP_ERROR_CHECK(spi_bus_add_device(VSPI_HOST, &cfg_eth, &spi_handle[i])); spi_bus_add_device(VSPI_HOST, &cfg_lora...

How sharing SPI for ethernet w5500, lora sx1276 and sdcard

Good afternoon, I have a firmware doubt that totally implies my hardware design. I'm designing a PCB and I wanted to share the same SPI for ethernet w5500, lora sx1276 and sdcard, since HSPI or VSPI make it possible to use 3 CS slaves. However, looking at all the ESP-NETIF API for w5500 and the mqt...

Re: RMT peripheral clk_div how does it work?


Hi guys, I have exactly the same doubts as the author of the post and tried to reread the documents several times and there were some loose ends in relation to the clock_div with the reception timing being changed ... Could someone there at Espressif could give a hand ?
