Here we go, easy work-around for the faulty lcd.image(): from m5stack import * buffer = open("/sd/images/test.jpg").read() lcd.image_buff(lcd.CENTER, lcd.CENTER, buffer)

@carles-b Great. Glad you got it sorted out and can begin enjoying M5Stack 😀

@BricoMS Thank you for the answer. I thought, that the hardware/controller of M5Stick and M5Stack are the same and that MicroPhyton is just another way of displaying the blocks of UIflow. I do not understand why M5Stack made no "fair" advertisement/documentation. For me it would be "fair" if they would write "ESP32-based support BLE 4.2 and WiFi not compatible with UIFlow"" I think, for some (many ?) users the UIFlow possibility is an argument for M5Stack/Stick. regards K.D.

Hello @michael_o you are welcome. I am glad to hear you got it working and thank you for reporting back here. Cheers Felix

As mentioned in the other thread, the missing step is transferring the canvas framebuffer to the EPD. If your loop function is changed as below, it works as you expect. void loop() { for (int i=1; i<7; i++) { canvas1.drawString(testString[i],20,20); /* m5epd_err_t UpdateArea(uint16_t x, uint16_t y, uint16_t w, uint16_t h, m5epd_update_mode_t mode); */ M5.EPD.WriteFullGram4bpp((uint8_t*)canvas1.frameBuffer()); M5.EPD.UpdateArea(0,0,100,100,UPDATE_MODE_GL16); delay(1000); } }

@bobolink FYI to myself If you have an engineering background--part of Micropython-- module 'dba: calculate dBA (A-weighting decibels) from an input stream of digital audio samples module 'i2stools': function to efficiently extract sample data from a buffer filled by I2S Signal processing (logical shifts--fractional multiply) on the PCM samples instead of hardware volume control gets the job done also.

Hello @grundprinzip no worries. Thank you for sharing your conclusion. I appreciate it. Thanks Felix

Hello @Arno nice! Thank you for the feedback. I am glad to hear it works now. @Zontex @m5stack : Maybe it would make sense to add a note in the GoPlus2 description about the incompatibility with M5Core2? And if not happened already maybe think about a modified GoPlus2 version where the GPIO for IR_OUT can be chosen through a dip switch to allow it to work with M5Stack and M5Core2 devices? Thanks Felix

@world101 survey filled

Hello again I found that when I switch M5Core2 firmware back to 1.7.1.1 and use it with UIFlow 1.7.2 (online) the error goes away and PaHUB works as expected. Thanks Felix

Hello @Nili I am sorry, I guess I wasn't clear. What I meant is a simpler UIFlow app (w/o ESPNow) only for testing purposes to see if the issue happens over time as well. Re UIFlow M5Paper power blocks: If you looks at the sticker on the back of M5Paper you'll see three digital switches (labelled MOS). One is for everything (main) except RTC, one is for the ePaper (epd) and one is for the external 5 volts (extern) ports A, B and C. Unfortunately there is no such switch for the touch - it is powered whenever the main switch is on. A possible workaround (untested) could be to shutdown M5Paper and wake it up through the RTC by using the block 'Restart after seconds'. That should turn the main switch (and with that the touch) off and then on again from the RTC. Cheers Felix

Das ist ja mal richtig gut :-)

@world101 said in M5Paper and API Key: @ajb2k3 Actually, most of the time when I flash new firmware with M5Burner, it does assign a new API key to my device. Maybe that is because I always erase the flash before burning the firmware. I just tried it and it gave me a new API key. @k33g give it a try. The Erase button is in the upper right corner of M5Burner. Then burn the latest M5Paper firmware. I thought i was supposed to but for me, lately, it looked to always generate the same api.

Hello, I haven't seen the Russian Moderators in a while. I expect they are all busy trying to work out how things work. Please be patient.

I'm trying to push for a unified API but the problem is that some of the devices are slightly different and require slightly different commands. Please add your request for a unified API to the suggestions list.

I CAN flash using the following from the command line: /M5Burner_Linux/packages/tools$ python3 esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 750000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x1000 /home/david/Desktop/m5stack/M5Burner_Linux/packages/fw/atom/UIFlow_Matrix-v1.7.2.bin I can then connect in UIFlow if I hold the button on the Atom while plugging into USB. However, I still cannot get the M5Burner App to work. I still get the Javascript error when I click the Configruation Button.

Hello felmue, it's no problem - i've ordered one and will have it by the end of the week. I looked to the scematics too ( - a little, I'm no specialist) and I found what you said. And I found more things that make me problems. I think the voltage from the external input is converted to 5V DC like the USB power. So I cannot use my DC12V motors unfortunately - I have to change to 5V types. (Now I unterstand, why they are rotating with so less power and slow.) Thank you and regards K.D
