  This issue was resolved. It was a simple misunderstanding of mine. "angle8.read_status" method was only for reading version and address. To read other registers, another angle8 unit method or normal I2C read work as expected. I realized I had been asking help to wrong people for almost three months, though they were also in M5Stack. I finally got the answer telling me it was my simple mistake.

  The Vcc on the "Grove" interface is actually stepped up from the 3.3V supply by a tiny SGM6603 chip (on a StickC-Plus). This chip can only supply about 1A, 1.5 absolute max. So this peripheral may or may not be suitable for all M5 devices.

  I've been working in raw I2C write and M5Stack have told me that there is an issue with digital read functions with the EXTIO2 and the Stamp EXTI/O but won't tell me where the error is? Be careful when reading and writing to the EXT2 StampEXT as it is very easy to corrupt the I2C address register.

  Trying to read the UHF RFID without initializing all required parameters first (UHF Zone, Channel etc ..) will give you nothing back. Try the UIFlow examples for the UHF RFID unit first. There you will find all the parameters you have to set for your country using the unit (https://www.gs1.org/sites/default/files/docs/epc/uhf_regulations.pdf)

  Interesting project! I have a UnitV2 (and the older UnitV) as well but only little experience with. My approach would be the following: To recognise only a few well known vehicles you can classify the image of the whole plate including car front (and drivers face) instead of the individual numbers/letters on it. This can be done with the V-training or with the online classifier function. For recognising single numbers/letters you can try to classify individual numbers/letters and then "read" the x-coordinates of the returned boundary boxes in ascending order to convert into string and then compare to a list/database.

  @boomvalt I have the same issue. The ENV III Unit works well when connected directly to Port A, it displays the temperature, humidity, and pressure correctly, but when I connect the sensor to PaHub, the temperature and humidity have still correct values, but the pressure is static and shows a negative number something like -513233.2. I have two units and with both, I have the same results. Were you able to solve this issue? Regards. Alvaro B

  Hi, I am using Atom Lite. It's the one from ATOM Stepper Motor Driver Development Kit (DRV8825) I am using UIFLOW(LITE) v1.9.8 downloaded using the Burning Tool I checked if the Burnning Tool would update the UIFLOW version, but I did not download the newest Burning Tool version. That must have been a mistake. Now I downloaded the newest Burning Tool with UIFLOW 1.11.0 on board and it is working correctly. Thank you Felix. Much appreciated!

  @hwtaro9 Well, it is intended to transmit video generated from the M5Stack to a monitor. The RCA unit "could" receive if there was a video decoder in the M5Stack, which there is not. The unit itself is a passive connector only.

  Hello @dsrc12 you are correct, the GPIOs for Serial2 in the M5Stack (M5Core) examples are incorrect. It should be 16/17 as you already figured out yourself. I've created a pull-request which corrects the three M5Stack (M5Core) examples. To get past wait ethernet connect multiple conditions need to be met: a) the network needs to have a DHCP server b) the IP address range needs to be 192.168.x.x c) the DHCP server needs to be compatible with ESPoE Unit re b) in case your network doesn't use 192.168.x.x you can modify it in this function bool Unit_PoESP32::checkETHConnect() { sendCMD("AT+CIPETH?"); _readstr = waitMsg(1000); if (_readstr.indexOf("192") != -1) { return true; } else { return false; } } Thanks Felix

  As far as I am aware, they were having problems rebuilding the server. It could also be an issue with the Great Firewall of China.
