Yanis said:So what could be wrong when using the SW102 ? Both displays use the same connections (P+, GND, Vin, TX and RX) so I guess the connector is intact. And yet, the SW102 doesn't work while the VLCD5 does. It's a mystery to me. Any idea ?
I found what the problem was !... and I'm really embarrassed about it : it was a wrong configuration of STVP. I chose stm8s105x5 instead of stm8s105x6... Now it works fine.
I focused on the hardware and didn't supect a software issue since STVP was saying that data was successfully written and verified.. It was indeed, but just not in a language the processor could understand I guess.
Thanks mbrusa, mctubster, Admiralrofl and Elinx for your help and sorry for the waste of time..
At least I can report about the compatibility of 20.1.C4 with the SW102 : it works fine, but the field weakening option seems to be missing from the motor menu (the menu ends with motor deceleration)
