Hi, Normally, you wouldn't add so much of logic to the reset condition in RTL and you wouldn't use the sequential clocking block always @ (posedge or negedge) for signals other than clocks and resets. If you want to sample the address pins , assign the incoming address to a register on the rising edge of clock and then in an always_comb (...)
Yes, because you are building HUGE arrays of registers, and not memories, becuase your "memory" signals do not bahave like proper memories: To make it infer a memory, you need to register the write data and read address. You cannot used the read data to immediatly write back to ram. I suggest reading some code guidelines on how to infer a (...)
Hi all, Im actually checking the Bluetooth connectivity among the RN42 BT card (as a Master) and HC06 card (as a slave). Im using Coolterm platform in order to register the RN42 commands to manage the connectivity. It seems everything is working properly using different commands, until I entry the BT connectivity command (C,<address>), which
I want to enable Reverse Loopback Mode (pre - CDR) in Arria 10 Transceiver PHY. In the User guide of the same, it is seen that I should perform a read-modify-write to address 0x2E1 to set bit 0 to 1?b1 for "serial loopback mode". But in the excel sheet for register map, it is given that 0x2E1 enables the rx_seriallopbken feature in the transceiver.
Visiting website: They offer a free trial version. Evidently you need to register first. They ask you to fill in email address and several more fields. The tab 'Free tools' lists several items.
You are using single byte read. Sure, it will be slower than sequential reading. The address counter register are self incremental. But only inside page size. For 24C64 memory page size have 32 bytes lenght. So, the auto incremental counter limited only with 5 bits. So, to make it works, you should take in accaunt this limitation. Basically, I reco
Hi guys, I have read about how Linux kernel manages memory itself and figure out that it uses Virtual address. To transform from Virtual address to Physical address it uses PAGE TABLE. But, where is PAGE TABLE stored? I have already found some articles in Internet taking about this problem but have not had any answers make me feel (...)
Hello, I am wondering whether the possibility of readback a specific address (for example 0000,000) from FPGA to the PC? Notice that the first for digits are Frame address and the rest three digits are the bit address. I think to its possibility via UART interface, but I am not sure about it. Kind helps are cordially appreciated. (...)
Hello every one, i am an engineering student and i have been given a project, i want to communicate with ADS1292R with my Arduino UNO, I have used the data sheet connections provided on page no 60. i am using 4 wire SPI configuration, and for a good starting point, i just want to read a ba
Hi, What i did: Googled for "kxtf9-4100 datasheet" Download Open Read. On page 12 it begins with the interface description. And there is the address. On oage 15 there is the register description. It took me about one minute. Why can't you do the same? Klaus
Hello, I want to know how i can change the register base address of a PS peripheral, DDR in vivado. I have checked in address editor but there is no provision to enter a new address.
Hi all, I am learning C language for PIC microcontroller and I am trying to write some data in general purpose register ( using 16F628a). Example in assembly language: TEMP1 EQU 10; declare address 10h as TEMP1 MOVLW b00001111; MOVWF TEMP1; May I know how can to declare address and store it like this code?
I complied the code for using ADC of lpc2138 in keil4. its hex file is generated but i cant simulate it in proteus. i included header file and all memory locations are correct still it is showing the error " attempt to read undefined register at address E0060010". What is wrong with the simulation?
I am trying to program a SI5338 with a FPGA. In the datasheet it is mentioned to program SI5338 through I2C. But it seems the protocol is a bit different than typical I2C. I think after sending SI5338 address (1110000) we dont need to send the address of the memory. Anybody has worked with SI5338 to help me about reading and writing to SI5338?
Anything that has memory will infer a latch. Should be read "A memory in combinational always block". I guess. There are some applications where you intentionally infer a latch, e.g. in some cases, a transparent latch is better suited as address register in a multiplexed processor bus than a flip-flop.
I have interfaced MCP7940M with AVR. I know working of I2C where in case of RTC write we use following sequence: 1. Start 2. Slave address+Write bit 3. register address 4. register data 5. Stop And of course after each byte there is ACK or NACK But actual confusion is in RTC read Definitely first two steps (...)
I need to configure pin AP0_14 for digital output. To achieve this I need to write 0 to bit 14 of 16-bit Port Mode register. The physical address of this register is: 0xFFC103C8 What should be the exact statement to write to this register using the physical address ? Please see section (...)
Hello, I am writing RTL for a module, which interfaces with a different chip on the platform. As part of the flow, this hardware module needs to do 10 register reads from the third party chip. Read flow is => Module writes address, valid and rw signals on the first cycle and the read data is available from the third party chi
Hi, 0x90 = read address 0x91 = write address If I use arduino uno to read the registers from AD7746, should I use 0x90 or 0x91?
You can't physically make hardware (synthesis) that can compare for X, that means both 0 or 1 are okay, basically the hardware generated is don't care so ends up being removed. I really dislike comparisons done using don't care values. If you have a don't care condition e.g. address decoding. // using a don't care condition on
