Hello @pop-k

I am glad to hear that. Thank you for reporting back.

Hello @pop-k

it looks like newer ESP32 Arduino libraries added an overloaded begin() function to also allow to setup an I2C slave. Whether the begin() for an I2C master or slave is called is determined by the linker by looking at the parameter types.

I2C master: parameter types are int, int, uint32_t

bool TwoWire::begin(int sda = -1, int scl = -1, uint32_t frequency = 0U)

I2C slave: parameter types are uint8_t, int, int, uint32_t

bool TwoWire::begin(uint8_t slaveAddr, int sda = -1, int scl = -1, uint32_t frequency = 0U)

Now some unit libraries (including the one for unit scales) are calling the begin() like this:

_wire->begin(_sda, _scl, 400000UL);

where _sda and _scl are defined as uint8_t.

So the first parameter _sda is an uint8_t and the first parameter of the begin() for an I2C slave also is an uint8_t (whereas the first parameter for an I2C master is an int) therefore the linker calls the begin() of the I2C slave. But we need it to call the begin() of an I2C master.

In short, try to modify below line in file M5Unit-Scales/src/M5_Scales.cpp from:

_wire->begin(_sda, _scl, 400000UL);

to

_wire->begin((int)_sda, (int)_scl, 400000UL);

to force the linker to call the I2C master begin().

Hello @mchott

in UIFlow 1.10.x have you tried the MQTT blocks under Modules - COM.X - NB-IoT?

Thanks

Hello @Marelli7

looks like TouchZone has been renamed into Zone.

BTW: you can embed code with three ``` on a new line before and after the code. Makes it easier for others to copy your code than having to retype it from a picture.

Zone topHalf(0, 0, 320, 120);

Thanks

Hello @fly4fun

thank you and thank you for reporting back. I am glad you got it working.

Most of those functions return true if successful (and false otherwise).

Thanks
Felix

Hello @fly4fun

try to modify the M5Stack example like this:
replace:

#include <M5Stack.h>
M5.begin();
while (!extio.begin(&Wire, 21, 22, 0x45)) {

with:

#include <M5Core2.h>
M5.begin(true, false, true, true);
while (!extio.begin(&Wire, 32, 33, 0x45)) {

Thanks

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 @AEisele55

on M5Stack you can select Setup - Switch Mode - USB Mode and reboot.

However on M5Core2 this option is missing. Setup doesn't have a Switch Mode entry.(Tested with UIFlow firmware v1.10.6)

Thanks

Hello @Marelli7

my bad. I was looking at this example.

Have you tried to connect the push button to GND and the input pin?

Thanks
Felix

Hello @Marelli7

I think you need to switch the mode to all input before trying to read anything.

ioCon1.portMode0(ALLINPUT);

Thanks
Felix
