Hi.! Can I use my CY7C68013A development board as a USB to I2C adapter to modify old printer chip eeproms? I have some replacement .bin files I need to flash onto the old chips. If anyone knows how to and which software can be used I would really appreciate it :P.
best regards,
Henrik
Show LessI have a project with the CY7C68014A that I am having difficulties getting the device to boot correctly. When the PC sees the device it says that the Device Descriptors Failed. When I checked the clock I noted that it was not working so I replaced it. When I hold reset# low clock will return the device is recognized by the computer as being there but fails the Device Descriptors. If I could get some help about what conditions need to happen prior to enumeration it would be great. Best I can tell 3.3V comes up, Oscillator stabilizes at 24Mhz then Reset# is released. At some point I know that the device will look for the EEPROM on the I2C Bus for firmware.
Show LessOur product based on cy7c68013a.
Most of them are Normally operating well. But some product did not be recognized about 2~3 times out of 10.
Power source, reset timing, i2c clk, data lines were good. However,there was someting very strange about i2c data voltage abnormal.
There was no pull up, or data transaction, but voltage level about 1.4v with pull down sometimes.(our voltage level 3.3v)
I haven't seen this symptom. Would you tell me how to debug this symptom? Wold you tell me how to solve this problem?
Show LessIs there an unique chip identifier for CY7C68013A? How to read it if there is ? Thanks
hello
i'm using CY7C65213 in parallel with TI battery charger, without programming issues with "usb serial utility" the CY7 makes conflict with the BQ battery charger, that normally detect automatically the charger type. If i do a programming of the CY7C65213 , enabling BCD, then all is solved. i would like to use the chip without "USB programming " in mass production of my boards. How to do? is there a way of do such programming issues trough attached MCU(attached to cy7c65213) instead of USB host ?
thanks!
Show Less我想这样使用CY7C68013A的CLKOUT输出37.125KHz的时钟,
请问能输出这种频率吗?
如果能,怎么样才能输出这个频率呢?
如果不能,其它pin可以输出这个频率吗?怎样输出?
I have referred the datasheet of CY7C65213 IC as they mentioned that it will support for RS232/RS422 and CY7C65213A supports for RS485 communication.Based on this information I have bought the CY7C65213A breakout board,it contains only two pins (TXD and RXD) for communication.But for RS422 communication has to need 4 datalines (TX+,TX-,RX+,RX-).In datasheet they mentioned two circuits for RS232 and RS485 only.
Can anyone share the circuit connection for RS422 to the CY7C65213 breakout board and clarify that breakout board supports which type of communiaction?
Show LessHi. Trying to develop a new product based on the FX2LP so recently purchased the CY3684 kit. The docs appear to be out of sync with the current software but believe we have the demo code working.
The first usb example is the bulkloop binary. Seems to echo to the host the sent packet of data.
We do not see any LEDs blinking nor the display counting up or down as per the docs.
Is our kit DOA or the latest firmware no longer uses the LEDs to permit other custom FX2LP boards to use the same demo code?
Believe our jumpers are correct. Will review the Keil code today but this should have worked in a few minutes. Now have to debug factory ready code?
If yes, where is the older but led supporting firmware we can download to continue our learning process. One that will match the documentation.
Out of the box experience has been poor. Well written docs but if the example or software do not match then the whole process is a waste of our valuable time.
Show LessHi,
Another day, another question ... 🙂
We are finalizing our Firmware.
One question regarding the Descriptor Name.
We want to display something like that :
"STMicroelectronics STiceX emulator"
I create the dscr.asm accordingly.
But the display of the device.name is corrupted (file attached) ??
Could you verify my dscr.scm ?
I tried numerous things but always strange name is displayed (Note that it seems to work if i reduce the name lenght ...??).
I'm using Eclipse, SDCC and your framework based onto bulkloop example.
Regards.

Hi,
We are wroing on a reference design using a PSoC 62 and a CY7C65215 as USB-UART bridge to debug. While usign the last one in bus powered mode we have noticed that if we connect the 5V USB to the CY7C65215 while there is no power on the PSoC 62 there is current flowing on the 3V3 supply of the PSoC (main supply of the PSoC). So basically the USB-UART bridge is pulling something up. Functionality is softwarewise is ok and debug messages work perfectly fine.
We have also noticed the opposite: if there is no 5V USB supply on the CY7C65215 side, then there is current flowing trough the 5V USB supply to ground when we connect 3V3 to the PSoC.
Is this the expecting behaviour of the CY7C65215 in bus powered mode? or do we need to configure anything else on the PSoC side? Configuration is ok per what we see on the serial configuration utility. Find attached some screen shots fo the schematics.
Thanks in advance
Ariel
