Hi Pete, Where is the source code containing this driver? almCreateEZ4Controller("ALM1", "IP1", "$(ALM_ADDR1)", 4, 200, 500) Mark From: Tech-talk <tech-talk-bounces at aps.anl.gov>
On Behalf Of Siddons, David via Tech-talk I have a setup with two identical USB devices. They connect as ttyUSB0 and ttyUSB1. I tried to set up an asyn interface using the following commands: drvAsynSerialPortConfigure("IP1", "/dev/ttyUSB0", 0, 0, 0)
asynSetOption("IP1", -1, "baud", "115200") asynSetOption("IP1", -1, "bits", "8") asynSetOption("IP1", -1, "parity", "none") asynSetOption("IP1", -1, "stop", "1") asynSetOption("IP1", -1, "clocal", "Y") asynSetOption("IP1", -1, "crtscts", "N") drvAsynSerialPortConfigure("IP2", "/dev/ttyUSB1", 0, 0, 0) asynSetOption("IP2", -1, "baud", "115200") asynSetOption("IP2", -1, "bits", "8") asynSetOption("IP2", -1, "parity", "none") asynSetOption("IP2", -1, "stop", "1") asynSetOption("IP2", -1, "clocal", "Y") asynSetOption("IP2", -1, "crtscts", "N") # almCreateController(AllMotion port name, asyn port name, board address, # Number of axes, Moving poll period (ms), Idle poll period (ms)) almCreateEZ4Controller("ALM1", "IP1", "$(ALM_ADDR1)", 4, 200, 500) almCreateEZ4Controller("ALM2", "IP2", "$(ALM_ADDR2)", 4, 200, 500) This fails, saying port ALM2 cannot be found. If I try to connect the second one also to ALM1, it complains that ALM1 is already registered. If I comment out the first device, the second one (with port ALM2) comes up fine. How should I be doing this? Pete. |
