I got a Dreamtech DTM0661 chip in a Voltcraft OLED clamp meter VC-590.
Anyone got at least the pinout of the interface to the MCU ?
Its like the DTM0660, but without LCD interface.
It´s connected to a EFM32TG842.
It hangs up in all AC modes. All other modes work fine.
We definitely need right to repair to have some chance of debugging.
