Re: what is the resolution for measuring pulse width on esp32-s3 ?

Hi,

The maximum PWM frequency is 160 MHz, which means the period is 6.25 ns.

We will provide more information about options to select PWM frequency and resolution in the updated ESP32-S3 TRM. Subscribe to documentation update to get the latest release. Hope it helps.

Re: ESP32-S2 ,ESP32-S3 的 ULP-FSM 和 ULP-RISV-C 功耗如何

如题,查手册得知 ESP32-S2 和 ESP32-S3 有两个ULP,基于RISC-V架构的功能似乎更强一点。 RISC-V的ULP有更多的寄存器和乘法支持,功耗是否会大于FSM的ULP呢? 谢谢。 Hi, ESP32-S2 的技术规格书中已经提供两个 ULP 的功耗数据,请查看 4.6 章节“功耗特性”:https://www.espressif.com/sites/default/files/documentation/esp32-s2_datasheet_cn.pdf ESP32-S3 的技术规格书正在制作中,相关数据也会及时发布。 您可以通过乐鑫官网的订阅页面 https://ww...

Re: Documentation Requests/Feedback

Hi Everyone, I don't know if here is the best place to report errors in documentation. But I found one simple and single error in : ESP32 Technical Reference Manual version 4.1 12.4.6 I²S Master/Slave Mode "The I2S_RX_START bit of register I2S_CONF_REG is used to enable a receive operation. When I²...

Re: Document Requests/Feedback

Hi, I was wondering if there was an inconsistency in the documentation with respect to the ADC1 channel mappings. Here is what I see from the latest docs: page 34 of esp32_datasheet_en.pdf V2.8: ADC1_CH0 SENSOR_VP ADC1_CH1 SENSOR_VN ADC1_CH2 SENSOR_CAPP ADC1_CH3 SENSOR_CAPN Notice that ADC1_CH3 is ...
