i have following problem and can't find a solution anywhere in the world wide web:
I have a digital multimeter with an USB port. I outputs data via an Serial to USB converter (PL2303).
On my PC i can decode the serial stream with the Supplier-Software. The protocol is compatible with the voltcraft-vc820 like seen in sigrok and QtDMM and sadly not simply ascii. I have an arduino mega with the USB Hostshield 2.0. There was an arduino library called "pfodMeterPaser" whcih is sadly not available anymore, but
can decode the serial stream of the VC820 and therefore the compatible stream of the BT-90EPC. The problem is the library needs an serial interface for communication and i just have the USB Host Shield connected to the Serial to USB Converter PL2303 connected to the Serial inside the Multimeter. I want to access the int or float number the multimeter sends inside my arduino sketch for further processing. Any ideas or solutions on how to proceed? I hope i gathered all necessary information.
Best regards and thanks or reading .
PS: I hope this is the right sub-forum
