dear all,oosggn oosggn oosggn oosggn oosggn oosggn i wanted to increase the number of serial ports, by using USB port inoosggn oosggn oosggn my board, how can we do that any 1 has idea?oosggn oosggn oosggn oosggn oosggn oosggn well i will use a usb to serial convertyer device, but for that ioosggn oosggn oosggn will require driver right?so where can i get that?oosggn oosggn oosggn oosggn oosggn oosggn well in desktop windows that converter is automatically detected, OSoosggn oosggn oosggn assigns a COM port Number also automatically, but to activate it inoosggn oosggn oosggn win CE what will i have to do? or which COM port it will take it as?oosggn oosggn oosggn oosggn oosggn oosggn any suggestions will be greatly appreciated.oosggn oosggn oosggn oosggn oosggn oosggn thanxoosggn oosggn oosggn john |

| 1 | rickli | Following possibilites do exist : - ask USB chip manufactorer for driver or source code - search microsoft site for drivers (suppose you have windows CE) - search internet for source code of drivers for linux for chips you are going to use in USB to serial h(at)ck them and adapt to windows CE - use multiple UART micro with usb device implemented and write driver for that device - use multiple UART micro (such as m32C mitsubishi) and connect it to your device by com port and use special protocol to access individual ports on that micro - use few ( let say atmel) micro where one is master and connected to pc via usart and provides connectivitiy to other slave mciros (each having separate uart) via SPI . Again special handling is required . - any other variants not mentioned |
