@kuriko said in Cardputer V1 to Cardputer V1.1 Upgrade?:

@M5xcro
The hardware update of StampS3->S3A only includes the antenna and BOOT button, so I think it can be fully adapted.

Thanks you so much!

using the mentioned changes hello_world example did compile and got uploaded to my core2. However , nothing is shown on screen, screen remains black.

Hi,
I have exactly the same issue with the coremp135. Any solutions meanwhile?
I'd like to use it connected via USB Serial and also upload programs, but now way.

GPI26は DAC です。
GPI36は ADC です。
SENSOR_VP は GPIO36 として入力に使用します。
GPIO34 ~ 39. は 入力専用です。

The Problem seems to still persist. Had the same issue and solved it this way.
Thanks @Dan-Perren and @teastain for the solution!

If this broke your cardputer here is how to fix it:
Before plugging your cardputer in hold the GO button and then plug in the cable. Cardputer will enter the download mode and you can then flash everything you want!

@scroggyg Hi, the SIT3088 is a "converter" from UART to RS-485. To write/read the RS-485, use the UART1 (TX:20, RX:21).
The setup below works, although I have to store the arrays first somehow, before setting them into my text box (top_box), as the text appears briefly and then disappears ...but I can see I am receiving OK.
I got the tab5 yesterday ...and RS-485 was the first thing I wanted to test it.

New M5Stack user here..I encountered the same problem with a CoreS3 and getting the same "invalid timer number" error messages when trying to configure the IR Unit. The S3 was reflashed to UIFlow 2.3.3, but this did not resolve the problem.

yuyun2000's helpful suggestion didn't work either as timer_id does not appear to be in the constructor for the IRUnit. Is this a more fundamental software problem?

The IR Unit with UIFlow2 is completely unusable at the moment

Just tested another release of UiFlow (version 2.3.3) for the Tab5... Unfortunately, I am seeing the same results that I saw with Version 2.3.2... -16Kpa without any air tubes connected to the M5Stack Air Tube sensor... Along with the i2c driver install error...

Hopefully M5Stack Team is getting close to resolving the issue... I was planning to use the Tab5 project I was working on for the M5stack Innovation contest but it looks like that will not happen due to the issues I am running into with finding an air tube sensor that will accurately work with the Tab5... Oh well... Hopefully the M5stack team will release an upgraded Air Tube sensor soon that will easily work with the Tab5... Until then, I will keep searching for a solution....

@onlysaadat My new StamPLC is exactly the same. Registered the device with M5Burner, It's on-line in UiFlow2, Loaded a fresh StamPLC demo - demo initially logged in and just flashed the monitor page no matter what browser is used on multiple computers. Cleared the monitoring user per M5s directions.

Now I get an invalid token no matter what I do.

Did you ever get your device to work with the demo or figure out how to fix the invalid token?
