SPI.setClockDivider(divider)
hi! Im using the ESP32-Wrover-Kit with the Adafruit screen library and a ADS1220 ADC, the library to this one was made by Protocentral. Connecting the ADS in the same SPI port than the screen and using another pin on CS this works well (because I will need the other pins for other parts of the proje...

Re: ESP-Wrover-Kit and ADS1220
Also if I attach an oscilloscope on SCK I can measure some 40MHz activity at the boot time, what is happening there?

ESP-Wrover-Kit and ADS1220
hi! I have an ADS1220 connected to the spi bus of the Wrover kit, wired as follows: ADS1220 || Wrover-Kit CLK > CLK MISO > SD0 MOSI > SD1 CS > CMD DRDY > IO16 The problem is when If I load any program to the board and the spi is connected, the board won't boot, I tried to disconnect the power from t...

Re: ESP-Wrover-Kit pin names in Arduino
I tried that to, but some pins don't follow the logic, I don't get anything from the pins
IO16, 17, 22, 36, 34, 39, 35, 32, 33 from the big row of pins, also how the pins in the SPI interface are addressed?
This should be specified somewhere, isn't?

ESP-Wrover-Kit pin names in Arduino
hi!
Don't know if this is already answered, I can't find it anywhere, how are the pins of the ESP32-Wrover-Kit (the big board with screen) named into the Arduino?

Re: ESP-WROVER-KIT USB input in hi-z and suspend mode
Found the answer for the second: I soldered a cable in the pin 59 of the FTDI chip and connected it to ground while I wa monitoring the USB connections on computer, it does nothing. So the suspend option is not used in the FTDI configuration, next is try to enable it.

ESP-WROVER-KIT USB input in hi-z and suspend mode
Hi! I´m making a power supply to power (among other things) the ESP-WROVER-KIT, this will run from a Li-Po battery then I will need to manage the charging of it. The BQ25895 (from TI) seems to be an interesting solution for the charging and management of the battery, this chip can detect automatical...
