Re: New ESP32-WROVER Ethernet Board

We would love to see the board design and BOM files to be shared though. Maybe a contantly updated GitHub repo would be useful. If nobody is going to sell it, I would rather put it together myself. Dont have a GitHub account, but there are a few solutions out there already. https://www.amazon.com/E...

Re: ESP 32 with OTA

Might be better if you gave some info as to what OTA "sketch" your talking about.
but odds are the information your looking for is in the code or in what you set up in menuconfig

Re: New ESP32-WROVER Ethernet Board

Hey Mike - what's the latest on this? We may have a need for such a product next year. Honestly, I just dont see enough people interested in it to put the resources (money) into making this a product for sale. It's going to cost quite allot to make these in batches to get the price down where peopl...

Re: error when trying to use I2C

ya... when it comes to reading you first write to the chip basically telling it Hey, i want to read from this register next, then you issue the restart, because if you'd issue a stop, you would have effectively told the chip were done, which we are not yet. After the restart, then you issue the read...

Re: error when trying to use I2C

Here is how I read a byte, and later how i read a word. esp_err_t readByte(uint8_t icAddress, uint8_t registerAddress, uint8_t *data) { esp_err_t espRc; i2c_cmd_handle_t cmd = i2c_cmd_link_create(); i2c_master_start(cmd); i2c_master_write_byte(cmd, icAddress << 1 | WRITE_BIT, ACK_CHECK_EN); i2c_mast...

Re: error when trying to use I2C

The best advise i can give when starting or using I2C on a new platform is use a I2C device that you can write to without having to read from. Reading is more difficult to debug on a new platform because you wont know if it's your writes or reads that are screwed up. Most guys don't have a logic ana...

Re: error when trying to use I2C

I should point out that the problem may legitimately be in the hardware, as our board is still in design. I just wanted to try to make sure my code was clean first.
Gotcha, depending on how long that will take, maybe just hook up any I2C device from sparkfun / adafruit or amazon.

Re: error when trying to use I2C

Just for giggles try increasing your ticks_to_wait, in i2c_master_cmd_begin. I think yous is way to short being a 1. Having it larger does not hurt. For instance, even if you set it for 1 minute (a total exaggeration) it would still exit as soon as it got the response back. https://docs.espressif.co...
