@felmue thank you for the suggestion for Ext Port for Core2.

@ajb2k3 said in Cheap camera module for M5Stack Atom Matrix: https://shop.m5stack.com/collections/m5-unit/products/unit-cam-wi-fi-camera-diy-kit-ov2640 I was not able to have my Atom Matrix interact with the OV2640 Unit Cam... [image: 1695488224647-d87c87d2-d834-4fbc-b634-88cddafb3b29-image-resized.png] @Exie were you able to connect your Atom Matrix with the Unit Cam and have the Matrix retrieve the Unit Cam output?

@gavin67890 I was able to get it working with 32/33 just by assigning with uart1 = machine.UART(1, tx=32, rx=33) which it looks like is the same the guy did in the video

Hello @DanK actually there is an AMS1117 version with exactly the output voltage you measured: 2.85 V - coincidence? From the AMS1117 datasheet - feature list: Three Terminal Adjustable or Fixed Voltages* 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V But yes, the input voltage is probably on the low side. Thanks Felix

@gavin67890 Thanks Gavin, i will have a play when i get a chance, shame really as i was looking forward to a larger screen on the M5 but if nothing else i now have something else to play with!!

So, the 4.6V is consistent with the schematic for the Stamp-S3, I see. The EN is connected to VIN, not VCC, via a diode, which drops it a little below the 5V from USB. This is different from the Stamp-C3, but I guess that's fine.

@bram The EN is the Reset input and is pulled up normally, and brought down to reset the ESP. While it does seem odd that it is 5V, mine does the same thing! My (ahem) LilyGO T-Display S3 Reset pin is at 3.3, which makes more sense. -Terry

Hello @H-Gruber below code works for me using M5Stack Basic or Fire (running UIFlow firmware 1.12.3): from m5stack import * from m5ui import * from uiflow import * import module setScreenColor(0x222222) lan = module.get(module.LANBASE) label0 = M5TextBox(21, 24, "label0", lcd.FONT_Default, 0xFFFFFF, rotate=0) label1 = M5TextBox(22, 58, "label1", lcd.FONT_Default, 0xFFFFFF, rotate=0) label0.setText('Hello 1') lan.tcp_udp_config('192.168.144.1', 4711, 1, 2) label0.setText('Hello 2') label1.setText(str(lan.get_if_config())) lan.tcp_send_packet('1234') label0.setText('Hello 3') lan.socket_close() label0.setText('Hello 4') Thanks Felix

Could be alsorts like incorrect supply voltage, incorrect setting on the module or issues with the code.

@felmue said in CORE 2 and how to chain 2x paHUB2: HUB unit many many thanks. Thierry

error found the Framebuffer fb was being freed before the SSLClient could finish writing hence the corrupted drive image.

Has anyone had success with MicroPython SD card access on the CoreInk? I just installed the firmware that seems to be about 1 week old, but all I get is different error messages when trying to mount the SD card. With slot 1 or 2, I get: E (8624) sdmmc_common: sdmmc_init_OCR: send_op_cond(1) returned 0x107 With slot 2, I get: E (8049) spi_master: spi_bus_add_device(373): host not initialized E (8052) sdmmc_io: sdmmc_io_reset: unexpected return: 0x102 With slot 3, I only get OSError(16,), without additional info. If anyone has gotten the SD card to work on the CoreInk, which slot and pins do you use? Is there any other initialization necessary? -- Correction: it seems the only reason I get different error message is because I commented out sd.info(). With sd.info(), I still get the original error. So still no SD card support at all?

@felmue it worked flawless, thank you so much!

Hi @teastain, Cool, thanks. I went ahead and ordered at risk JST XH 2-pin from Adafruit, 2.5mm seems spot on for the connectors of GoPlus2. http://adafru.it/4872

Hi guys it looks like the Micro-RTSP library needs to be added to the project. Note: with that library I can compile the RTSP example; but I have not tested if the result actually runs properly. Thanks Felix

@ekalfwons : Hi, I'm struggeling now at the same point. Do you have a solution after that time now? Cheers, Olaf
