Connetc 2 Arduino to same SRAM
Hi everybody. I wuold like to start some experiments with SRAM.
I would like to create a simple computer using 2 Arduino connected to a breadboard where there is a SRAM chip.
The first Arduino, the “CPU”, will execute some code and generate several datas (for example a Game of Life) that it will write into the SRAM chip.The second Arduino, the “VDC” (Video Display Controller) will read from the same memory the datas and will display them into an LCD.
My question is: how can I connect the two Arduino to the same RAM?
Is there a way to tell an Arduino not to access the RAM when this is busy ( for read/write) with the other Arduino?Don’t ask me with I don’t use the same Arduino for both tasks: in this experiment I would like to learn how to share the chips between mCs.

If you take apart a classic gameboy cartridge it basically just has an addressing chip and a ROM chip on it. Would it be feasible to take out the ROM and instead connect the addressing chip and the rest of the addressing pins directly to a set of SRAM chips? For example you'd have a circuit powered by the arduino that would write into the SRAM chips connected to the gameboy through the cartridge and when it's done you could turn on the gameboy and it would read from the SRAM banks. This would mean two circuits have only the SRAM ...I am testing a board that has external SRAM. Apparently the SRAM is relatively sensitive to the soldering heat from the manufacturing process, and so careful testing must be done to check integrity of SRAM for newly manufactured boards. What is the best (bare-metal) way to test SRAM? I have a driver that initialises the SRAM for read/write access. My first thought is to run tests such as: 1) Set all bits in SRAM to 1, and check that the SRAM was properly written. 2) Write the digits of Pi in SRAM, and check that the write was done properly. ...Hi, I would like to store data in a 16kByte SRAM. When the memory of the SRAM has for example reached 10kByte it must send it to a FLASH sd- memorycard of 1GB. Meanwhile the SRAM is still storing new data in the SRAM cells. Does someone knows if reading and writing simultaneously in SRAM is possible ? And is there a maximum write/erase cycle for SRAM? (not mentionned in ATmega datasheet) Thank you !I have seen IC2 chips such as EEPROM - 24LC256 http://ww1.microchip.com/downloads/en/devicedoc/21822e.pdf and SRAM 23A256 http://ww1.microchip.com/downloads/en/devicedoc/22100c.pdf that could be connected to the Arduino for increased memory and I have a few questions. If you have written a sketch that needs additional memory would these chips perform well or would the Arduino have to run relatively slow to utilize the chips resources? I realize you could use a SD card instead of EEPROM but, would EEPROM be faster or slower? Would the SRAM be helpful and quick for storing chunks of data before transferring to a SD card? All knowledge is welcome, ...Hi, Can someone please expalin to me how the Arduino decides on flash or Sram? e.g. I have written a 4k program to the atmel328P which has 32k flash, 2k Sram amp 1k EEprom. The IDE shows the amount of flash available but the code runs in Sram. I need some clarification on this isue. Thanks.I use a Atmega88 as a power controller in a larger system with another processor. I have some state information in SRAM that I'd like preserved on the AVR side. What I've observed is that if the other processor uses the serial programming interface (SPI) of the AVR to simply read Flash or EEPROM data of the AVR, when the AVR runs again, the SRAM contents are not affected. (when I disable clearing of SRAM at init in CV-AVR). But when the other processor reprograms that AVR (uses chip erase/write program memory/write EEPROM memory commands) then it looks like the ...Hello, I have Hex files to program on a BQ4010MA-150 I have tought that it would be easier to remove the chips from the boards they are on to program them They are Sram 8Kx8 and my Hex Files reflect that Any Ideas... I would make a shield to insert the sram chip... ThanksHere is the problem. Code is located in 0x1000_0000 (Chip select 0), it is an external flash. The program can boot off there and run. I need to be able to write to the flash. I tried appending the keyword "__ramfunc" and it just jumps to the area 0x4 (Not sure what error that is). I am a computer scientist, with no formal computer engineering training. And i am the sole person working on this project. So i am a bit out of my league. I have a flash driver written, and i am able to get the Manufacturer ID and Device ...I have an STM32 dev board with some external SRAM. I would like to execute my code from that external SRAM, but my processor only supports booting from the Flash, internal SRAM or System memory (a part of the internal SRAM). What is the easiest way to run code from an external SRAM? Notes: I load code with OpenOCD through JTAG, and I use GDB.First, I'm a geologist, not an EE guy; I can do simple sketches, but this stuff is way over my head. In short, I'm using the Arduino Pro in an electronic flow controller for educational river models we build (see www.emriver.com. A pro programmer wrote some nice code for me as a favor (in C++); it works, but we're bumping against memory limits; we have several large arrays, most of which are used to run "hydrographs" -- simulation of a flood; a curve that starts small, climbs to a max, and then tapers off. I am cleaning up and refining things because he's ...Hello I'm trying to access SRAM 62256 but all I get is 0xFF or some random data. SRAM is connected as in the schematic. MCU is a PIC18F452, xtal 8MHz (HS). Here is code for reading and writing: Code:I have an ARM Cortex 3M (reference manual here) connected through the FSMC (Flexible Static Memory Controller) to a Spartan 6 FPGA. In turn, the Spartan 6 is connected to some external SRAM. I need to production test the SRAM. As I see it, I have two options: - Write an SRAM driver directly from the FPGA (without involving the Cortex). - Route the Cortex memory pins through the FPGA to the memory. Reading through the specs of the SRAM, it seems that writing an SRAM driver for the FPGA is a relatively difficult task. I am therefore inclined to ...Hi Im looking for SRAM even 1 kb would do, preferably SPI . So any of you guys know of any chips easily available. Microchip 23k640 SRAM SPI would be perfect but i cant find it anywhere. RegardsDear all, Here i have some doubt please help me. I am interfacing 1Mb SRAM to LM3S3748 processor using SPI protocol. For this i used 4 GPIO pin and configured as SPI protocol. I can able to write and read data from memory location of SRAM separately. My doubt is that in LM3S3748 limited in built RAM is there so i cant store all my ...guys, i want to know about the size of sram that we have used on arduino, how to do that?I've been thinking about doing something like this for several years. Every so often there is some discussion on this forum about using multiple memory chips in parallel. When the CS came out I purchased some extra 23K256 SRAM chips. I figured I'd want to learn how to use the 23K256 chips that are on the C3 so I might as will have some extra for other Propeller projects. I also wanted more memory to use with my machine vision project so I attempted an eight chip/bit SRAM driver. I stacked the eight DIP chips on top of each other and soldered the common ...I've heard from friends that using an Arduino Uno with a removeable chip (vs. the configuration in which the chip cannot be removed) I've heard that with the standard Arduino Uno,one can program the chip, upload the sketch, pull it out of the Arduino and then connect it to a breadboard (or wire up with soldering) to replicate Arduino functionality in something that's tiny. My question is what are the limits of using this chip vs. an Arduino. I'm trying to save on size primarily and cost secondarily. Can I pull out the chip and wire it to sensors, motors ...Hi All, Recently we tried to add a SRAM on EBI1 CS0 to act as the framebuffer on 9263. We found that: 1. without any initial code to SMC1 CS0, only use the reset value (0x01010101 for SETUP,...,0x10001000 for MODE), the SRAM is accessable, but can not BYTE access 2. write 0x0 to 0x70000000, it only change the high half byte. The 0x70000000 read as 0x0000FFFF. 3. change the SETUP to 0x02040204, the system will down Anybody use SRAM on EBI1 and can share piece of init code? Thanks a lot.Hello all, I am looking to expand the memory I have available in an AT Mega 1281. I understand the datasheet offers considerable information regarding this (which I've read) but I was hoping to get some recommendations for a 64K SRAM chip and an octal latch that people have used. Over at Mouser and Digikey, I found it difficult to find 64KB SRAM. It was either more or less than I needed. And some was arranged in 16-bits instead of 8-bits, which I think is what is needed with an AVR. I have one further question - once the compilar ...I have been experimenting with the SparkFun TCM8230MD camera and my Arduino. My goal is color object tracking but for now I am just learning the basics about interfacing with the camera and working with the data stream. Since the camera runs at 27MHz and Arduino at 16MHz, I created a frame buffer "shield" for the cam to write to and the Arduino to read from using a SRAM from an old hard drive and some binary counters. The cam writes directly to the SRAM at 30 frames per second in any resolution, synchronized by the cameras vertical, horizontal and data clock ...
