Hello @robouden

hmm, running UIFlow2 on my M5CoreS3 and measuring current on USB-C I get about 140 mA / 5 V.

Is your M5CoreS3 maybe charging the battery?

Thanks
Felix

Hello @smily77

no, AFAIK there is no specific 'how to' for M5Tab5 - only the generic about how to build your own Arduino library using Arduino library builder or how to use Arduino as ESP-IDF component. See links above.

Thanks
Felix

SoftwareSerial mySerial(1, 2);

void setup() {
  mySerial.begin(115200);
}

void loop() {
  mySerial.write("Hello world!");

Sorry, we are now fixing this problem. Please use 2.x temporarily, we will fix this problem in the future.

keep 2.x

Hi guys

the ESP32C6 is connected via SDIO bus to the ESP32P4 but unfortunately the GPIOs used in Tab5 differ from the GPIOs used by the ESP32P4 eval board.

In other words the pre-compiled Arduino library is setup to use SDIO GPIOs which do not match the Tab5 hardware.

So in order to use Arduino you'll need to pre-compile the Arduino library yourself using the Arduino library builder or setup the build system to use Arduino as ESP-IDF component. Both ways should allow to modify the SDIO GPIOs accordingly.

Note: the SDIO GPIOs used in Tab5 can be found here.

Thanks

@liujinyou Did you burn the correct version of UIFlow for your specific cardputer?
Did you erase the cardputer first before downloading and burning the latest cardputer UIFlow2 version?

Hi guys

please find some information and pictures of my M5Tab5 with soldered M5Stamp LTE-M module here.

Thanks
Felix

@wsanders
looks like some kind of version problem, have you upgraded all libraries to the newest version?
