ipsych in UIFlow 1.7.1 is a Problem with the Core 2 and the grove port, a update to UIFlow 1.7.2 will solve the problem https://community.m5stack.com/topic/2672/uiflow-1-7-1

@fraramon
Try use the sd with the UIFlow IDE

@fraramon
Check the format of the SD-Card, ist must be FAT32

@ove said in UIFlow 1.7.1:

I installed UIFlow_Core2 version v1.7.1_core2 on my Core2 and now I have no power on port A.

If I add "power.setBusPowerMode(0)" in the Python tab before any Units are initialized the power is returned but I can not do this with blocks.
The power is restored until the Core2 is reset.

I detected a similar problem with the Core2 and UIFlow 1.7.1

Testing with the ENV- and the TVOC/eCO-units at port A of the Core2 drives it into the I2C-error message "I2C bus error(19)". After rolling back the Core2 to UIFlow 1.7.0 these units works with the Core2.

I think there must be a I2C-bug in UIFlow 1.7.1 for the Core2, at least for port A.

@lukasmaximus for my win10-pc the problem also seems to be solved, many thanks

@lukasmaximus on my IPad ist seems to work fine, the problem occured on a WIN10 pc, tomorrow i try it again on WIN10.

How many write operations are maximal at the EPROM possible?

@felmue said in Avoid M5Stack - it is a waste of time:

Hello @Efried

I think you might be correct, both modules seem to use UART2 (GPIO16 / GPIO17) to communicate. I am afraid you'll need to use a different UART port for one of the modules in order to have both working at the same time. The GPS module is already prepared for that. Please have a look here:

... this is the same with the M5GO CHG Base.

@kris the DAC is part of the python unit module. In UIFlow, if you select the unit DAC, you hav acces to the DAC elements.

On the </>Python tab you find the python code:

Critical bug with the word "global" at python code transformation from UIFlow 1.6.2

@world101
... i agree with you, there is a critical bug in UIFlow 1.6.2.

E.g. using the word "global" causes the python code transformation to replace the following text with all defined variables. Or defining a function with parameters causes a global definition in this function with the given paramater (look at my short test_global-program):

with variables: value, var01
var01 is set to "Bug with text global"

In function "dosomething" with given parameter "value" i placed an Execute-code block with following content:
# Test function for global error
# look for global error
# look for Global error

when switching to </>Python - page you can see that UIFlow made incorrect code transformation:

This code cann not run because:
Line 17: the identifier "value" is redifined as global
Line 27: the text after the word "global" is replaced by "var01, value" and the closing quotation mark is missing

As you can see, each time the word "global" appears, the following text is replaced by all defined variables (see lines 18, 19 and 27).

In line 20, the word "global" begins with a capital letter which doesn't lead to mistakes in code transformation.

Note:
With UIFlow 1.6.1 desktop version this problem does not exist!
