Re: WROOM32 v1.0 vs v1.1 different trace antenna layout

Sorry to make you confuse. ESP-WROOM-32 provided by sales department now is v1.0. v1.1 is a better design. If you want to design your own module, you can use this reference design. Since v1.0 has been mass produced and has gained many certifications, we have no plan to MP v1.1 version again and will...

Re: ESP32 Price

The public price of ESP32 is not decided yet. It is ESP31B that we have once provided to those beta testers. We have stopped providing ESP31B, since even Espressif does not have stock now. So no one could use real ESP32 to have FCC report before July except ESPRESSIF. Thank you for the information t...

Re: Evaluation of ESP32

Sorry, our beta tester program has closed.

The chip will be in mass production soon in March. And you will find it on market during Q2.

Re: ESP32是一款什么样的芯片?和ESP8266有什么关联和区别

ESP8266 是单核 Tensilica L106 (32位MCU)的Wi-Fi芯片,主频最高可达160MHz。

ESP32 是双核Tensilica L108 (32 位MCU)的Wi-Fi芯片,主频更高可达250MHz,性能更强,内存更大有400KB SRAM。另外还集成了蓝牙BLE。

由于ESP32的MCU性能更强,内存更大,可以处理包括音频、视频在内的更复杂Wi-Fi应用。还可以应用在需要蓝牙和Wi-Fi共存的IOT场景中。

Re: Little Boy crying under Christmas tree

Sorry, there are so little beta samples to meet followers' need.
We have arranged new production. Maybe you will not miss it in Chinese New Year.

2. CPU响应中断时,通过查询中断控制模块判断是哪一个外设产生了中断
当 CPU 的中断源上只接有一个外设中断的时候,不需要通过查询判断是哪一个外设产生了中断。 但当多个外设接入同一个 CPU 中断源时,则需要先判断是哪一个外设产生的中断。
查询方法:可通过读取中断控制器的寄存器,获知哪个外设产生了中断。

这两个寄存器与外设中断的对应关系如下。
除此方法以外还可逐个查询各个外设内的寄存器,以判断哪个外设产生了中断。

Re: Translation Help

p31 1. 配置外设产 的中断 某 个 CPU 外部中断源 每一个外设中断都有一个对应的寄存器,将此寄存器设置为对应的 CPU 中断源序号,就可以将此外设配置到 CPU 对应中断源上。 函数原型如下: INTR_MAP_REG_A :外设中断对应的配置寄存器。 PRODPORT_INTR_MAP_0 :外设中断对应配置位在的配置寄存器中的位置。 xxx :CPU 中断源序号。 ‣ xxx 若为 6、7、15、16、29 时,表示外设中断并未配置到 CPU 任 中断源上。 ‣ xxx 不为 6、7、15、16、29 时,表示外设中断配置到了 CPU 对应中断源上。 配置寄存器名称、配置位名称与...

p31

外部中断源序号为 0 5、8 14、17 28、30 31。通过配置寄存器,可以将 44 个外设产生的中断接入这 27 个中断源。当多个外设中断接 CPU 的同 个中断源时,这些外设中断信号以 “或” 关系产生CPU 中断源信号,当 CPU 响应中断时,可通过两种 式查询具体是哪个外设产生的中断:
• 方式一 :查询中断控制器的寄存器,得知是哪 个外设产生了中断。
• 方式二 :分别查询可能产生中断的外设的部寄存器,判断是哪一个外设产生了中断。
