Good morning (o; As I decided to develop a GPIB device based on STM32F MCU I did a first setup based on a Nucleo-F207ZG board with attached 75160/161 transceivers... In my test code I just check for DAV and set NRFD and NDAC accordingly.... Interestingly...when I send for example a *IDN? query to my test device, which doesn't send back any data (not yet ;o), I don't get any errors in ibterm....so is this normal that ibterm doesn't wait for data and just closes the communication? Currently I just send out the received commands/Data out the USB CDC device... Sending *IDN? I get in my USB console: CMD: 40 CMD: 3F CMD: 25 DAT: * DAT: I DAT: D DAT: N DAT: ? CMD: 3F CMD: 20 CMD: 45 Or does it misread EOI and therefore closes the communication? thanks in advance richard _______________________________________________ Linux-gpib-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-gpib-general
