Hi, I interfaced a Micron MT9T001 with Spartan3 evaluation board, I can save a fragment of image on SRAM, and now deciding which USB controller to use so that I can transfer the raw image data to PC directly from the sensor. The bandwidth for the output data needs 30MB/s (640*480*98fps). I used FT2232 before but it supports up to 1Mb/s only, so I am finding a IC USB controller that can support...


SMT32F207 FSMC interfacing SJA1000, SRAM, Compact Flash

Hello, I would like to use the STM32F207 in order to interface up to 8 can channels by means of the SJA1000 can controller IC. In addition there is need for Compact Flash interface, plenty of external ram and flash memory. The Flexible Static Memory Controller (FSMC) peripheral seems that it could handle these requirements, but I'm not familiar with STM32 and so I have some questions. First ...

I need some idea to realize a structure like this: MCU LCD CONTROLLER TFT LCD I'm using a 32 bit MCU (ARM7 or Cortex-M3), supposed to drive external FLASH and SRAM. The TFT LCD has to be a QVGA-sized panel with no internal dedicated controller, has the company does not want to be be tied to a specific display model. We have this model to try with: http://www.data-modul.co


Reading PCMCIA cards while connected in a different system

I'm looking for a way to read data from a PCMCIA PC SRAM card while it's in a device. This might sound extremely weird, but basically, the device writes data to the card, but we'd like to read it without using the device's protocol. Is there any way to do this ? Or can we replicate the writes to a different card that we can read ? Any help is appreciated ! Wim

Hi! Sorry if this is not the right group for the question but it seems to be the closest to the topic I could find. The problem is this: I'm trying to implement a simple processor-based project on the NanoBoard using Altium Designer. I'm using TSK51 and external memory chip (128K SRAM) on the NanoBoard and my task is to connect them by writing a VHDL memory controller. I've created a...

Hi, I am working on a small design using Intel 386EXTC processor. The design has a 512KB Flash and a 512KB SRAM. The processor user manual says "The chip-selects generated by this unit can simplify external "glue logic" by providing signals that can be connected directly to the chip-enable inputs of external memory and I/O devices." My question is if I am using 8bit memories, is it possi...

I am trying to drive a 320x240 LCD using an ARM microcontoller and some SRAM, all for an average of less than 1mA. I cant find an ARM7 MCU with a 320x240 driver (bw, 1-bitter STN, slow refresh). Where can I find an external LCD driver that can do all this for 40uA or lower? Or better is there an ARM7 mcu with a built in LCD driver to match this lcd? The MCU must have an external memory inte...

Newbie question : Suppose that the Atmel AVR internal flash memory is to small to store my new asm program into it, and suppose that you can't make your program smaller than what it is (graphics are in SRAM, did it all in ASM and so one. ps: this is a theoretically question).
