How are you fixing setup violations? If you are shortening data path to meet setup check, I don't see why that will produce new set up violations. If the data travels fast, then fixing setup may produce hold violations .
hi i trying to receive data with usart on stm32f4_discovery board. my code do send data with my configuration,but it does't receive anything as what realterm said:( .i check the RXNE flag also ... but it does not set either . does any body khnow how to handle this ? i try so many examples on the net ... still facing (...)
STA doesn't check the functionality of a design. It verifies the design against a set of timing constraints. In your case it would analyze timing from the nearest launch edge to the rising edge of the divided clock, i.e. the period of the launch clock +/- the clock skeew between the two clocks.
- Are there some error messages while simulating? - Are you using variables? Then you could try to set all variables to "nominal" - You can try to check if the solution is available by creating for example a data table with the gain.
It is not related to compiler version problem i think you need to set TXC bit manually while you are using simulator. In real time it sets automatically for successful data transfer, so if you set your TXC bit I think you will able to run your UART simulation
hi friends, I am trying to interface spi in SSP at LPC2478. but I can't able to interface . I am using Keil 5 . I have check with debugger all control register set correctly but i cannot move the data from temperory register to SSP1DR i dont know what is reason . can anobody pls explain interfacing details and example code.
set uart receiving interrupt at the interrupt vector you can check received data and save on register rest of time you can implement portd blinking hoped this will help you
Hi, I have a question on how to simulate this situation. I have a working UART with parity checker that I synthesized to a Spartan 3 FPGA. If the parity check is incorrect, a signal will be set to high. This signal I routed to an LED on the FPGA board. I use Putty on Windows to communicate with the serial port and enter (...)
This is an experiment to check if digital data transmission was done accurately or not. Ok, so here's what is done: The part where the value is lower than the value set at trigger level is detected, then the number of samplings of the finer offsets are set, and only those parts were horizontally shifted and (...)
Hi, check the data sheet, think you will find many of those ports are mulit-functional and you need to set or change other parameters as well as just input/output; example Analogue or Digital. Also check for any CONFIG parameters that affect the port pins.
hi i use only microchip basically, to use spi you have to configure two register SSPSTAT and SSPCON.SSPCON register is used to set the spi mode if either slave or master, the sampling, the rising or the falling edge clock...etc The SSPSTAT register is used to check if the data was sent or not.pretty easy in case of pic microntroller. i did a (...)
During the DFT insertion stage, we check for the DRC rules such as: Clocks are controlled Asynchronous set/reset are controlled Clock gating cells are enabled bidirectional pins are set to in/out during shift etc.. But which are the DRC rules which are checked only in ATPG step and not in Scan (...)
We can set the SPI freq by changing the values of TMR2 prescaler value. Timer2 Output / 2 Ref: PIC18F4550 datasheet page no. 199 chk SSPCON1 register BIT SSPM3:SSPM0: Master Synchronous Serial Port Mode Select bits Note: 4: PR2 = 0x00 is not supported when running the SPI module in TMR2 Output/2 mode.
PIC 16f1527 datasheet 22.1.1.7 Asynchronous Transmission set-up: set the CKTXP control bit if inverted transmit data polarity is desired. But BAUDxCON register not have CKTXP bit?
thanks for your reply. i check all register and flag that i set are correct . this same codein is worked in old model wavecom gsm modem but new model gsm modem wavecom modem not work for tis same code .
The part of data set you posted is not a set of integers. These are rational numbers. Try to plot your data set and check if it looks like origin (dont pay attantion to values, just shape). Maybe your noise added is very great. Or post the full code
Basically it looks OK although I do not have the same compiler to check it. I would note that you set the "uart_receive_flag" every time a character arrives, regardless of whether it caused an overrrun error or not. If the UART is not configured properly it may still receive data and you correctly reset it to clear the (...)
If possible, check out the timing for the LCD clock. 50us high clock should be enough when using 4MHz PIC clock. Also, I'm not aware of mikroc programming and the available functions, but I see no configuration in your code for the Lcd_Init() function. How do you set 4-bit or 8-bit data transfer mode? From your code I understand you're (...)
any state is possible, so you need to set it up to your desired state or clear the files on start.... or you can check from data sheet on the Function register file summary they do state the thresholds!
Hi All I have a very simple question that I "kind of" know the answer to. But I would like to see what you guys think. I have a series of digital data for example 001110001100000111100. I want to count how many 0 to 1 transitions are present in the data. For the data set in the example, I should get 3. The simples (...)
