但由于esp32c3只有一个i2s,因此为了测试max98357不得不单独使用一个esp32c3模块,于是从何获取音源数据又成为了一个难题。经查询,初步确定了三个方案,a)直接读取SD卡或者文件系统中的文件播放; b)将一块esp32c3上inmp441的数据传输到另一块esp32c3上,再由其驱动max98357播放声音; c)直接调用他人的库,播放网络...

ESP32S3io复用:I2S和串口by learn123321 » Sat Oct 12, 2024 2:32 am 请问,我现在想接入两路I2S,和一路UART,但是我空余GPIO只剩余GPIO33-37,51,52,33-37给一路I2S,另一路复用GPIO10-14,GPIO17,18给串口可以嘛1 post • Page 1 of 1 Return to “硬件问题讨论” Jump to ...
Re: ESP32-S3 - I2S during Light Sleep by MicroController » Tue Feb 13, 2024 10:35 am There may be some combination of clock gating/'force PU' settings which could work, stopping only the CPU but nothing else. Light sleep however, among other things, clock-gates and powers down the...
I have success on ESP32-S3 I2S with polling using i2s_write. However, it doesn't ensure that the tx data is transported orderly. Interrupt would be a better option. I have tried on ESP32 I2S successfully with DMA and Interrupt. But since the IDF 4.4+ changed the register, for ex, I...

Hello Team, i am having troubles operating the I2S0 in PDM TX DAC Stereo Mode at high sample rates (>75kHz) on a ESP32-S3. First there is a little bug in the driver file i2s_pdm.c (ln 38): clk_info->bclk = rate * I2S_LL_PDM_BCK_FACTOR * ...
