Hey all, So it seems like interrupts while in light sleep are a no go, because the CPU's (ESP32 dual core) are clock gated. Simply put, the cores don't receive clock pules. The only problem is we have an interrupt that is short and unlatched. It's just 2.5 uS in length. I tried to attach a light sle...

And I appreciate that, you'd know this better than me, but my suspicion is companies use the ESP32 because it's an MCU, with built in WiFi, BLE, for IOT and other devices. Pairing one ESP32 with another is much more expensive, time consuming, is more difficult to maintain, double the power consumpti...

Huh? Are you actually wondering what be the benefits could be of a more simple, smaller, cheaper SoC with lower power consumption?! Uh-oh... :D Well perhaps lower power consumption. Smaller and cheaper? Well STM32 has some absolutely tiny micro processors (with terrible software) that are in fact c...

Hello, We're using the ESP32-Pico-v3-02 for our project, to be mass produced this spring. As we look for a path for future upgrades, we're struggling with our ability to continue with the ESP32... There doesn't seem to be something in the pipeline that has: - Required: Dual Core (240 Mhz or higher) ...

Hello, I am seeing the same bug here on v4.3.7. Changing connection parameters consistently causes a crash with the following stack. Anyone else? Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled. Core 0 register dump: PC : 0x40015788 PS : 0x00060830 A0 : 0x80049eba A1...

Hello, I'm flashing firmware to another chip using the ESP32. It must be done in a single transaction with the CS line held low for the entire length of the transfer. After some digging, it looks like the SPI driver can only transfer a single transaction that is smaller than the amount of heap in in...

Were you ever able to solve this issue? Simply put BLE & Light Sleep has been broken since 4.4.x and still is here on 5.2.1. Intermittet crashes with RTCWDT_RTC_RESET. I've tried everything from "extra crystal current" to other boards, and everything in between. Something is just wrong and the CPU d...

We're using a combination of ESP32 (wonderful software guys, so much easier to work with than the STM32) and the STM32 for sound processing. The two MCU's are on I2S, 16 kHz, Left & Right channels, no MCLK. ESP32 as Master With the ESP32 as master, the BCLK appears to be a bit too slow. On the STM32...

Hello, We're running IDF v.4.3.5 with good results and was wondering about the following statement, that appeared in the v.4.4.x version of the documentation for esp-idf: On ESP32, touch wakeup source can not be used when RTC_PERIPH power domain is forced to be powered on (ESP_PD_OPTION_ON) or when ...

After hours with the logic analyzer, the timing doesn't even follow the spec sheet when sent from its windows configuration utility. I ended up using the following library and adding the needed delays with esp_rom_delay_us.
