It's built like this image. My solar panel is a 5 volt 60mA panel. The battery is a 500mA lipo battery. The output on the right (in the image the dc-dc step up, my timercam is connected) in the image connects to the onboard connector of the Timercam. I've used the original plastic shipping case to construct a waterproof case for the components.

Hello everyone
Also bought Core 2 All examples do not work either.
I am a little desperate.

Thanks.

@ameero95 said in M5StickC Plus cant drive an Adafruit sensor module (3.3V) through the Grove port using the Grove to STEMMA QT adapter.:

STEMMA QT

try level shifter maybe?

Thank you.
I hope M5 or espressif can fix this bug soon.

Hi Paopao,
I am in your same situation, I have been trying to communicate UHF-RFID-UNIT with Aton Lite and I don't know the right code.
Could you spend the code to start my project?

Thank you

Have you checked the voltage drop of the batteries as each motor spins up?

The OV2660 version is EOL, but you can buy the OV7740 version here: https://shop.m5stack.com/products/unitv-k210-edge-computing-ai-camera-ov7740
(There are no noticeable differences between the 2 versions)

Yes if you google "m5stack timer camera examples" there are multiple examples ..

I have tried several but so far not able to get good resolution .. i think the software is not referencing the PSRAM corrrectly because the picture save process errors at about 450k.

I am going to try this tomorrow .. https://github.com/mumris/M5Stack-Timer-Camera-X

void drawJpgFile(fs::FS &fs, const char *path, uint16_t x = 0, uint16_t y = 0, uint16_t maxWidth = 0, uint16_t maxHeight = 0, uint16_t offX = 0, uint16_t offY = 0, jpeg_div_t scale = JPEG_DIV_NONE); void drawPngFile(fs::FS &fs, const char *path, uint16_t x = 0, uint16_t y = 0, uint16_t maxWidth = 0, uint16_t maxHeight = 0, uint16_t offX = 0, uint16_t offY = 0, double scale = 1.0, uint8_t alphaThreshold = 127);

As you can see you don't need the extra values because they're automatically SET, even
M5.Lcd.drawJpgFile(SD, "/wifi.jpg",110,40,100,100,0,0);
does not work though, Why are the libraries not working properly?

And while you guys fix the nylon 3D printed case design, please also add holes for the infrared emitter.

I see the IR emitter LED on the PCB but there's no holes on the case to let the light out.

And if you are wondering, yes, I do need it.

It would be helpful if you guys posted a file type better than STL so I can actually edit the 3D model myself. Like STEP or IGES.

Hello @ebr61168

I am out of ideas at this point in time, sorry.

Have you checked with M5Stack support or the shop / store you got your M5Paper from?

Thanks
Felix

Hi @felmue

Ok, but thank you for loking into it anyway.

Best regards
Kenneth

Hi @MauriceX111 I've also just got an M5 Paper v1.1 (my first experience of M5 or ESP32) and it is a very nice product but I'm also struggling to find out things... Very grateful that this community - and especially @felmue - are here, otherwise I'd be completely stuck!

Felix pointed me at the code that the device ships with.

Searching this, I found here the following code

// Battery _bar->setTextDatum(CR_DATUM); _bar->pushImage(498, 8, 32, 32, ImageResource_status_bar_battery_32x32); uint32_t vol = M5.getBatteryVoltage(); if (vol < 3300) { vol = 3300; } else if (vol > 4350) { vol = 4350; } float battery = (float)(vol - 3300) / (float)(4350 - 3300); if (battery <= 0.01) { battery = 0.01; } if (battery > 1) { battery = 1; } uint8_t px = battery * 25; sprintf(buf, "%d%%", (int)(battery * 100)); // _bar->drawString(buf, 498 - 10, 27); _bar->fillRect(498 + 3, 8 + 10, px, 13, 15);

So that doesn't help with finding out whether the battery is charging; but it does seem to be the best available way to represent the charge level.

HTH.

@felmue OK! I tied the very complicated TOF sensor because it is in-line code, no damned Library and...
...It works on C3.
The expected activity on the G1, G0 was as it should be.
So, thanks for your help, I will use this event as a plateau and work to trouble shoot the ENV myself, probably with in-line code, No Lib !!!
Vielen Dank!

Thanks @felmue. When I looked at your code I realised my mistake. I'd been treating the RGB LED as a simple LED, not an RGB. I should have read the spec sheet! It's all working as expected. I have also managed to get the M5Stamp attached to Blynk.
