I am helping to port Mecrisp Forth to the PSOC and am having trouble loading my program to the eval board. I am using the $4 CY8CKit-49-42xx board with the more functional 4245 device. I started with a UART loopback program and modified it to be "bootloadable" which means it can be used with the bootload on this board. This is firmware on the board that accepts commands to flash a pro...


USB2.0Mass Storage controller + 8051 Low Power?

I have been trying to find a device with a MPU core and a USB 2.0 interface. Prefer if the MPU is 8051 but it doesn't matter. Must be low power with suspend currents under 30uA. I have seen the Cypress units and they are almost perfect but the wake-up time is ~5ms. My current design is up and running in around 120us after wake up. It is a data logger so it wakes up as fast as every 10ms ...

Hi Guys, I have attempted to perform a USB Bulk read transfer over an EZ-USB FX2 development board. Vendor requests work fine, but using the usb_bulk_read() functions returns the following error message: "usb_submit_async: submitting request failed, win error: The parameter is incorrect" So far, we have established that the problem is on the peripheral (8051 FX2) side, and *not*...

Hi, I'm using the Cypress CY7c67300 (a.k.a EZ-Host) chip in a dual-role (eg. both USB host and device) application.

When I monitor the serial line with an oscilloscope I can see the following: - I send a proper COMM_WRITE_...

Hi all, I am trying to temporarily disable my EP6 slave FIFO which is set to auto-in during data stream, and I am running into trouble no matter which approach I take. A little background: I'm grabbing data from a camera whose Line Valid (LV) signal clearly indicates when there is valid data, since it's only active when Frame Valid (FV) is also active. So, my current approach is to direc...

Hi Folks - I'm looking at a quick project that needs: - 16-bit AD data acquisition, - Ethernet connectivity - modest processing requirements (32-bits best) - ideally contemporary ARM supported by lots of toolchains RTOS etc. I'd love to use Actual Fusion (but only 12 bits) or Cypress PSoC (but no Ethernet). Quick look around shows lots of 12-bit solutions. Tern has high res AD but old x...

Im looking to encorporate usb2 into my embedded app. At of all the solutions, the Cypress FX2 IC, seems the best, it has an 8051 core with usb2. Has anyone used this? Jungo sells firmware for this chip (WinDriver), but is it meant to work along side of my application firmware in the same 8051?? It has very little ram, so Im guessing the jungo driver runs exclusively on it, and my applic...

I am using a Cypress EZ-USB FX2LP (low power version of the FX2) on a 4-layer PCB that I've designed. I have created a very simple GPIF waveform that wiggles a couple of control signals and reads/writes data via the 16-bit data bus. I am only implementing the single read and single write waveforms at this time. Once I started testing my firmware I noticed that the values on the data bus ...

But NOT using EZ-USB which I suspect is messing my programme up. Perhaps it does not allow for the extra memory in the FX2LP. I have written code to download a program (in hex or iic format) to RAM or EEPROM, but that was when the FX2 was running vend-ax (or our software, which is derived from it). I just need to get a file handle and then use some library functionto send 0xA0 command...
