Thanks for the hint. That code won't compile: 'MLX90640_BadPixelsCorrection' was not declared in this scope. If you comment out the reference to MLX90640_BadPixelsCorrection it compiles and works OK. In the meantime I got a UIFlow version working more or less. Download from https://github.com/wsanders/WSThermalCore2Cam/blob/main/thermtest1.m5f. It's pretty crude but it autoranges OK if the temperature differences aren't too bad. Using ASCII art pixels because it's faster than drawing two rectangle (you STILL can't draw a borderless rectangle in UIFlow!) Sorry - I deleted my previous post accidentally. It was full of errors anyway.

It seems if I set the i2c rate to 100Khz this works.

Thanks lot @felmue, I really appreciate. I had guessed the output format can also simply be changed by writing to the ov2640 register. At least it says it on the main page, that the other settings would be available. Anyways, I am fine with working with jpg, but unfortunately I cannot reproduce the jpeg yet in an RGBA8 texture with the given resolution from the provided buffer (~8000 bytes). The photo taken is just white/grey. [image: 1667220436017-8224550e-e22d-41b3-90ed-9e59588730eb-grafik.png] [image: 1667220583609-0cf88125-bb78-4c0a-9827-97a54f63315b-grafik-resized.png] I am just sending the uint8_t buffer over Serial for (uint32_t i = 0; i<frame.size; i++) { Serial.write( frame.buf[i] ); }, and read the bytes to a texture, while filtering for Jpeg Start ff d8 and Stops ff d9 (which I find). [image: 1667221062882-ee39c219-d6c9-44ee-8297-692ab61868f1-grafik.png] The length / size of the buffer ~1000-3000 for the 160x140 resolution, seems suspiciously low though, compared to the relatively good image shown on the Core2 display. Hm.. I assume the buffer has to be uncompressed based on compression settings found in the Jpeg header bytes.. -- Got it working by decompressing jpeg

Oh I forgot, and this is how the Serial2 is initiated (MrCore2 and M5CoreInk) : Serial2.begin(115200, SERIAL_8N1, RX_PIN, TX_PIN,true); // Serial2.begin(9600, SERIAL_8N1, RX_PIN, TX_PIN); //Serial port 2 initialization delay(300);

@ajb2k3 tday I've loaded one of old firmwares with old M5burner and it is same...only LCD backlight is on all the time not a single thing being displayed on LCD, if I use ERASE option then backlight is off

Hi, I only have one switch available at the moment, but I will see if I can test with another one. Using the FTDI to set the IP without a full reprogramming would be ideal, but I might as well just reprogram it with a static ip. Thank you for the help!

Hello @nebosa check the ADS1115 datasheet (linked here under Related Link). Section 9.5.1.1 I2C Address Selection describes how to change the I2C address. Looking at the board of my AMeter I can see that it is partly prepared to select a different I2C address. One can move a 10 k resistor from one location to another to switch between 0x48 (default) and 0x49. To select 0x4A or 0x4B requires a bit more work, I am afraid. Below picture illustrates my modification to change the AMeter I2C address to 0x4B. [image: 1665964944391-m5stackameteri2caddr0x4b_20221017.png] Thanks Felix

Hello @wkearney99 I don't see 4-Relay module in UIFlow (yet). No, I don't think you can use the UIFlow for 4-Relay unit since the I2C registers are different. 4-Relay module uses register 0x10 to control the relay vs. 4-Relay unit uses register 0x11 to control the relay and LED (register 0x10 is a control register). Documentation for 4-Relay module. Documentation for 4-Relay unit. BTW: you could use the default I2C Master blocks (under Hardwares) to control the 4-Relay module. Thanks Felix

Thanks terry

Thanks

@teastain That was my hope too and I was disappointed to find it controlled by an esp32 but not wifi accessible :(

@gleon m5 core, m5stick and m5paper

@felmue Thanks for you fast reply Felix! I will.

Thanks

Its a 4A SMD fuse. I have a guide here on replacing the fuse is the SSR but it works the same for the Ammeter unit. https://www.hackster.io/AJB2K3/replace-the-fuse-in-the-m5stack-ssr-unit-477a23

Hello @xha1e PoESP32 is a unit and meant to be controlled via Groove serial connection using AT commands. May I ask what is the reason you'd like to modify the preinstalled AT firmware? That said, if you look at the schematic you'll see J2 (Download Socket) in the bottom right corner. J2 can be used with an USB serial adapter to modify the preinstalled AT firmware. Note: J2 is internal and not populated. Note: the preinstalled internal firmware can be altered / replaced using Arduino IDE. But please be aware that restoring the preinstalled AT firmware requires the ESP-IDF build environment (which is different from the Arduino IDE). Preinstalled AT firmware source code and build instructions can be found here. Thanks Felix

Hello @a1development I am glad to hear you got it working and thank you for reporting back. Thanks Felix
