As far I can recall, things need to be configured are:
I still got the "--- Waiting for zero" message and it wont go any further.
By default the A&D Fx series scale won't automatically populate the measurement to the serial port you need to enable that.
If you enter the Cleanup mode you should be able to read the current weight from the scale. Are you getting anything?
I enabled it. Got the factory settings and the AutoTrickler settings. I also played with all settings but no change. When I enter the Cleanup theres a black screen and when the turn the nobe the stepper will start to run. But no display output. Maybe my scale is bad ? But communication works because the scale will correctly respond to the calibration mode.
There are two issues according to your description.
I´ve got 3,3V on RX and TX . RXD is 0V not changing. TXD got -5V
Yes its the latest firmware.
The 3.3v on RX and TX indicating your serial port is sitting idle. No message is received nor transmitted.
RXD and TXD should measure 12V if nothing happen. Reading 0 at TXD is certainly a bad thing. You need to check the cable (NULL modem or straight through) with the corresponding jumper position.
FYI I made a change from v1.0rc to connect PIN5 of J6 (RS232) to the GND. If you made the v0.3 the PIN5 is floating, for which you may need to solder a cable from PIN5 to the ground somewhere on the board.
Here are some solutions to diagnose the serial issue.
Hi I created a discord server for open trickler users. https://discord.gg/ZhdThA2vrW
Please feel free to join the server and let's work on the comm issue.
After some Digging on the Discord i got the Problem and the Fix. It was the v1.0rc Board and a FEMALE header
Glad the issue is fixed. Will close.
Hey, which settings do I need to change on the scale? Currently it stops at "Waiting for Zero". Allready changed the baudrate to 19200bps. So in the "settings" the scale calibration will work. Greatings
