Re: SD card 0x107 errors after Aug22 commit 0532d37

Re: And again someone who has problems with esp32 and sd cards

At last, after days of experiments, hours of disappointments, I did it! I've got 3Mb/s write speed in fat file system with 4-line mode: I (178) MAIN: Initializing SD card I (178) MAIN: Using SDMMC peripheral I (3185) MAIN: host.slot=1 host.max_freq_khz=50000 I (3185) MAIN: Mounting FAT...

Re: espefuse.py could not write efuse in Windows msys2

I had the same problem: could not complete 'espefuse.py set_flash_voltage xxx' on windows msys32. Process hung on 'Connecting........__ '. The esp-idf installation was made 9-aug-2017. I updated esptool from https://github.com/espressif/esptool today (8-sent-2017) and now the command is executed per...

Re: And again someone who has problems with esp32 and sd cards

Friends, can anybody say me about read/write speed of SD cards in practise? I've connected a SD card via SPI (esp-idf/examples/storage/sd_card) and have tried to write 1Mb, it took about 10 seconds per megabyte. Is it normal? I used microSDHC 32Gb and microSDHC 2Gb, host.max_freq_khz = 32000. SD Car...

Hi, Ritech, could I put an eye on your ported version of onewire.c?

Re: ESP32 TFT display library

Why did you commented out call to gpio_set_level() in spi_master_lobo.c? //gpio_set_level(handle->cfg.spics_ext_io_num, 0); GPIO.out_w1ts = (1 << handle->cfg.spics_ext_io_num); In this case we can't use GPIO 32,33 for PIN_NUM_DC. Maybe you have a reason to do so? I uncommented call to gpio_set_level...

Re: ESP32 TFT display library

I found why 'make makefs' does not work. 1) These files are absent: components\mkspiffs\component.mk components\spiffs_image\component.mk 2) Lines in components\spiffs_image\Makefile.projbuild .PHONY: flashfs .PHONY: makefs .PHONY: copyfs should be changed to one line .PHONY: flashfs makefs copyfs 3...

Re: A2DP Sink: how to get bit depth and sample rate

I have used 44100Hz / 16 bit as default, but I saw that 16000 - 48000Hz are possible. Is there a way to be notified what the SBC decoder actually found? To define sample rate I do check in callback for A2DP sink: in case of ESP_A2D_AUDIO_CFG_EVT I do: a2d = (esp_a2d_cb_param_t *)(param); uint8_t sb...

Re: A2DP Sink: how to get bit depth and sample rate

Hi Mike, I've gotten the A2DP example to work too, but when I play audiobook over Bluetooth I've got rattling sound on PCM5102 connected to esp32. It's rather hard to understand artists' words. I don't know in which direction to dig. I've got SBC stream (mcc.type==0) i2s is inited as: i2s_config_t i...
