Build tools for 32-bit Linux

Following instructions in the ESP-IDF documentation about Linux setup it is not possible to download the 32-bit version of the Linux build tools 1.22.0-61 (nice to have because I'm also running Xubuntu on a netbook). Currently I installed 1.22.0-59 (GCC 4.8.5) but with the latest Git update the comp...

Re: ESP32 as an SPI ADC sampler and Wi-Fi broadcast questions

Thanks for your answer, this sounds very interesting. Do you think it could be possible to have a preview of the SPI driver? While my question is about the timing I would like to be sure that SPI and GPIO are fast enough to control 4 devices (even using 4x GPIOs as chip select).

ESP32 as an SPI ADC sampler and Wi-Fi broadcast questions

I want to port an ESP8266-based (+ host CPU) solution to the ESP32. Currently I have a number (2-4) of high-speed ADCs controlled by a host CPU via SPI using 16-bit data words (hence need 2-4 hardware controlled CSn lines). Samples are then stored to an SD card or transferred via UART to the ESP8266...

ESP-WROOM-32 pin 32 (GPIO20)

Hi all, just start using the ESP-WROOM-32 (DevKitC and in a near to come custom board if some prerequisites are met). Want to know if there is a particular reason to tie pin 32 (IO20) to pin 37 (IO23) as seen in DevKitC/J schematics. According to the ESP-WROOM-32 schematics in data-sheet 10-29-2016 ...
