Good day everyone,new at this forum but had an epic ISA system for the past threeyears.On the blue side up site, under transponder,it says that senddata(2,0,0x0b) will produce a -dash-on display 0.Does not work for me.I have defined display 0 as beeing 1 digit like in the example but i fail to see how this senddata would produce a - .From the manual, the documentation of that command is notvery clear and gives examples of point outputs.Can anyone help here ?It does sounds very nice to have '-' displayed on the 7 segmentoutputs display and would love to make this work.thanksRegards,Daniel

Hi!senddata syntax is as follows:senddata(,, )module is the module number. I think it's always 2. row corresponds to the ICM7218 chip, each chip can drive 8 digits and you have four of them on every display module. So, on your first module you have row 0 to 3, on the second 4 to 7 and so on. data is one byte large. The leftmost 4 bits are describing which digit you want to select, the other 4 bits describe the data you wanna send. So, if we want to blank phisical digit 14 (that's the 6th digit on row 1) the leftmost 4 bits in the data parameter would be 0b0110. To dash a digit the 4 rightmost bits are: 0b1110. Together this would appear as 0b01101110 or in HEX: 0x6E When we don't want to have a decimal point we have to inject bit 7: 0b11101110 or 0xEE in HEX.the full command would be: senddata(2,1,0x6E) with decimal point or senddata(2,1,0xEE) without.For exact data that you can send look into the ICM7218 datasheet. regards,steve

Thanks Steve...got it to work...daniel
