#108592 - USBXpress and other examples on SiLabs Responding to: ???'s previous message |
I'm beginner so probably I'll use USBXpress, but it will be good? USBXpress encapsulates complicated details of USB, such as enumeration and packet splitting. You can enjoy USB communication without hustle. However, it still holds basic USB characters. Developing on USBXpress provides a good opportunity to learn on USB characters without worrying about USB complexity. In this link, I summarized the difference of USB from RS232C. "Differences from RS232" http://www.8052.com/forum/read.phtml?id=101960 At the same time, USBXpress has many limitations. When you face its limitations, I recommend you to migrate to home-brew USB project, based on SiLabs USB examples. because I want to convert signal to SPI, SMBus,RS232 and 1-wire. These serial protocols share almost same characters. Replacing front end handler, they can be implemented over the same USB communication structure, either USBXpress or home-brew one. 'F32x equips SPI, SMBus and UART peripherals. 1-wire is implemented by bit-banging or 1-wire bridge chip. 1-wire bridge chip on Maxim/Dallas http://para.maxim-ic.com:80/Default_1...oducts.htm Where I can find usb_bulk example. On www.silabs.com. But where? SiLabs three USB examples, USB_bulk, USB_INT and HID_Example, are included in the latest IDE update, downloaded from this "Software Downloads" page. See C:\SiLabs\MCU\Examples\C8051F32x\ after installation. http://www2.silabs.com/tgwWebApp...nloads.htm Another USB example on SiLabs site "USB FM Radio Reference Design" http://www.silabs.com/tgwWebApp...MRadio.htm AN264SW - including firmware source http://www.silabs.com/public/do...N264SW.zip Tsuneo |
