How to transfer data of SPI bus and I2C bus over Serial bus - Raspberry Pi Forums

-

is possible use uart , spi bus on raspberry pi?

how can data spi , i2c buses on uart?

there software called "radio skypipe 2" windows accepts data either through serial bus or through tcp.

want try on serial bus , on tcp.

if got feeling bit confused, here bit of info may clear mind.
  1. i2c, spi, , usart specific hardware interfaces of pi, independent of each other.
  2. only usart, used communicate other systems, used serial interface, uses 3.3v digital levels, can add chip converts txd , rxd signal rs232 levels, long distance connections.
  3. i2c, "ic ic communications bus", used pi "talk" specific "i/o expansion ic's", such i/o expanders (for gpio's) or adc's , serial eeprom store small amounts of data permanently
  4. spi mean special peripheral interface, has similar function i2c, i2c provides "bus" pi can talk multiple devices, spi used talk 1 other device, small lcd screen, faster i2c


yes, can read data i2c device (like adc), , send on usart serial line system, i2c isn't communications bus in sense usart serial communication port is, question asking bit strange.

pi can read data i2c, or spi device, , sent on serial channel yes, no i2c device "sends" data pi forwarded usart.

hope helps.

hi, what's correct implementation sort of thing ? i want add list. content list user entered textbox. contents of textbox put inside list, 1 below other.....i started venture using rowcount property, can't work....i wanted simple alert see current rowcount....i have following code.... import mx.controls.alert; import mx.controls.listclasses.listbase; public function addme():void { alert.show(string(showlist.rowcount)); } but constant value of 7. don't understand how ? you want length of dataprovider. rowcount refers control's visible rows. has nothing data. to add item, use dataprovider api, probablyadditem(). tracy More discussions in Flex (Read Only) adobe
