@felmue I assumed so and tested both cases - tx: 17 & 14; rx: 16 & 13. In case of GPIO 14 and 13, I am not getting the invalid pin error but not receiving any data from the serial device either.
I used UART count of available in place of Remain Cache as mentioned in this post - https://community.m5stack.com/topic/5714/uart-remain-cache-ui-flow-2-equivalent
@felmue I'm getting Invalid pin error with the UIFlow1 example using UIFlow2. I used tx=17 and rx=16.
Traceback (most recent call last):
File "<stdin>", line 23, in <module>
File "<stdin>", line 13, in setup
ValueError: invalid pin
@felmue @Hnerik-Schmidt could you share your working code? I'm having issue with M5Core2 + RS232F + UIFlow2.
I tried the below code to read from a serial port using RS232F module. I set the GPIO pins 16 and 17 to On on M5Core2. I just see None as the output.
I tried Execute mpy code that I found in another thread, but I get the same output "None".
@felmue That seems to have fixed the issue. Thanks for your help.
I'm testing out rfid scan feature on M5Dial. I have the blockly code as in the screenshot attached. When I run the code, the very first rfid card scan works fine in reading the content of the card. Recurring rfid card scan takes either 20-50 seconds or just don't get scanned.
And every now and then I get ETIMEDOUT error. I tried a while loop to look for a RFID card presence before reading from address 4. Seems to have helped with timeout error but still seeing significant delays beyond the first scan. Appreciate any help.
Note: The factory default program for M5Dial RFID works very well in scanning UID and displaying without any delays.
I have almost identical code for M5Stick Plus with RFID module attached. I didn't have this issue.
