Posted on May 17, 2011 at 12:07Hello. I'm using a upsd3212c with vcc=5V And interface 74AHC00 with vcc=3V Will TTL-levels reliably drive the inputs of the uPSD? That is, will a 2.4V signal from logic be interpreted as a hi, or do I need the 0.7Vcc r...
Posted on May 17, 2011 at 11:55Hello. Thank you for your answer. I test it at the DK3200 and working ok. But it doesn´t work on a microcontroller what i buyed. I tested the oscillator. Thank you .
Posted on May 17, 2011 at 11:55Hello. I am using uPSD 3200. I'm trying to use the channel PWM4, but frequency calculations don't match. I write: PWMVP (0xAA) = 0x02 // Variable PWM Period Reg PWMVPW (0xAB) = 0x01; // Variable PWM Pulse Width sfr PSC...
Posted on May 17, 2011 at 11:54Hi, I have a question about memory access. I´m loading the example AN1560 in evaluation board with the uPSD3234A. The memory map of my system looks something like: Legend: MF =Main Flash SF=Secondary Flash MF == 0x800...
Posted on May 17, 2011 at 11:54Hello, We are trying to implement a debug system of the code for upsd323x . In that we have mapped boot flash as code & primary flash as data in a combined space mode. How should set the initial value of the VM registe...
