A problem about UART in BF533! - aileenferng - Jan 18 9:29:39 2008
Hello! My program is that I want to control SONY D100 which is a camera by BF533 by the RS232. For example, I can send command just like "88010605050301FF" which is hexdata from BF533, then the camera will tilt. Now I can control the camera by PC.And the ADI BF533 can also communicate with the PC by the terminal program, for example the Windows Hyperterminal.But the camera cannot communicate with the BF533. I use UART and non-DMA, polling mode. I donnot know why. Thank you very much!

The configuration of UART port of PC and UART port of BF533 might be not the same. If you can control the camera from hyperterminal( PC) then u can be control camera from BF533. U need to check Tx and Rx line of UART is goes to Rx and Tx line of camera. Plz refer the schematic of BF533 Ezkit. Let me know is it working or not. Hope this helps!! ----- Original Message ----- From: aileenferng To: a...@yahoogroups.com Sent: Friday, January 18, 2008 1:01 PM Subject: [adsp] A problem about UART in BF533! Hello!

This is typical problem. Check Tx from BF533 is connected to Rx of camera. Satish Godbole, Group Co-ordinator (DSP), Wavelet Group, Unit No. 10, Plot No. 59, Amchi Colony, N.D.A.
