I would need some information about the planned lifecycle of the Fujitsu FR60 family, and the Softune toolchain.

I am aware that this (a public forum) is not the place to discuss such things openly.

So, can somebody point me to a place where/whom to ask ?

Thank you !

Hello All, Me and my friends are build a project and there is a chip which is obsolete that could not find on the market. The part number that we are looking is CY128P160-167AXC. Can anyone give us any suggestions on where to find the chips?

thanks!

Hello Team Infineon,

I am here to ask for your recommendation on
the best  dev kit or Evaluation Board that comes with touchscreen kit or
Infineon MCU that can control 3.98 inch LCD touchscreen and more features,
in order to develop touch screen device.

kit / MCU Specifications in need :

-supports LCD : 3.98 inch, 320X480, RGB, 40pin 
(client considers ILI9488, a-Si TFT LCD single chip driver : https://focuslcds.com/content/ILI9488.pdf )

-supports 2D graphics acceleration

-supports single touch feature (capacitive)

-supports PWM controllers for buzzer feature for audio

-better than Arm Cortex-M0+
-32-bit MCU
-6x USART, timers
-ADC, DAC
-comm. I/Fs
-1.7-3.6V
-RAM size : 144kB or better
-Flash size : 256kB or 512kB
-compatible to use NAND flash of size 4~8MB
(in order for the device to support user interface in
three different languages(Korean, Chinese, English))

-preferably has easy development environment to develop the LCD touchscreen device.

The client was considering the following ST-micro MCU before,
because of its simple guidance to the sample project guide.
https://www.st.com/en/microcontrollers-microprocessors/stm32g0b1ke.html 

If you can recommend MCU or/and evaluation board that can support above feature with design guidance for LCD touch device project, that would be greatly appreciated to share it with the client.

As always, thank you for your considerations to help and bring our business forward.

Hi,  There,

We are using CYUSB3KIT-003 (the P/N of the chip is CYUSB3014) to design a camera. We need to send a leader and a trailer as single transfers before and after each frame. So I used the override mode to add the leader and trailer. I modified the AN75779 to test the override mode.

I add the leader in the GPIF CB function and the trailer in DMA CB function. I also added 2 states in the GPIF state machine: SOF0 and SOF1 to get the SOF signal from the camera (it’s a pulse 5ms before FRAME VALID signal ) to interrupt the CPU. In these 2 interrupts, I add the 52 bytes Leader of the frame. The resolution of my design is 1920*1200 Mono8 (1 byte per pixel) and the frame rate is 30 FPS. I set the buffer burst size to be 18K (18*1024). So there should be 125 transfer of 18K blocks, one leader and one trailer for each frame. I used AMCap to start the transfer though I know there will be no video in the viewer. I only need to see the USB traces.

But the trace I got is not as my expectation. The data blocks will sometimes be 124, and sometimes there will be one data block between the leader and trailer. The app will stop running after several seconds with an EP_UNDERRUN error. You can see the details in the attachment.

Please kindly give me some help.

Thank you much in advance.

Hello Everyone:

      We are not able to set 'WEL' bit in Status Register 1, or even read back what is written in Memory. We are using a FPGA to interface with Serial Flash S25FL256S... . Below is the sequence of operations.

• Power up
• Wait for Tpu of 300us
• Read JEDC ID (Instruction 0x1F). Correct data is read back.
• Issue WREN (Instruction 0x6)
• Issue Erase Flash Array (Instruction 0x20, address bits[23:0] = 0x0)
• Wait for 11 seconds
• Issue Status register read (RDSR Instruction 0x05), reads back 0x0. Expect WEL (bit 1 to be set since WREN was issued).
• Issue Page Program (PP, Instruction 0x2, address[23:0] = 0x0, 4 Bytes of data).
• Wait for 2 ms (for page program to complete).
• Read Status 1 register, reads back 0x0.
• Read Flash Array (Instruction, 0xB, address [23:0] = 0x0, ), reads back 0xFF all bytes. So data could not be stored.

    I am attaching some waveforms showing the operations.  The file names of waveforms indicate the type of operation being performed. These waveforms are from Xilinx Vivado ILA. The signal names are mapped as below.

SCK:                      jb_cp_mem_clk_OBUF

CS#:                      cp_pMem_csN_OBUF

IO[3:0]:                cp_mem_in_OBUF[3:0]

Below is some information about the operations shown in the waveforms.

1) Read JED ID & Issue WREN.jpg:    This file shows that reading of JEDEC ID is working. After reading the ID, we are issuing 'WREN' Instruction to set the 'WEL' bit.

2) Erase Flash Array (P4E).jpg:     Before writing we are erasing the sector at address 0x0.

3) Read Status register 1, RDSR1 .jpg:    Reading Status Register 1, read back data is 0x0.

4) Page Program & Read Status Register.jpg:   Write data to memory and read Status Register 1, read back data is still 0x0, WIP bit not set.

5) Read Status Register & Read Flash Array.jpg:  Read status register and read data from memory. Status register is still 0x0 and data read from memory is all 0xFF. Four bytes were written and four bytes read back.

     Did we miss anything from the datasheet? Are we doing something incorrectly? Please help!

Thank you so much.

Best regards,

In the appnote: "AN_1802_PL52_1803_235257: Part II: Using the LLC calculator with Rules of Thumb (ROT) and fast
verification with LTspice A guide for adapting the LLC calculator to design rules based on exact mode analsyis of LLC converter", a future part III aimed at resonant components selection and criticity, such as max current issue in low resonant capacities, is often quoted. Is such document available?

Thanks

Hi Cypress,

I recently looking into the 4700S series, but i found that there are not much code example for this series, only 8 of them. 

I tried to follow those examples from PSoC4 such as 4200 series etc. but they are significantly different now.

Is there any resources you can share?

The way Cypress update or extend your component library is quite hard to do the sustaining process. All the functions and components are part specific, which is not quite user friendly, just my opinion.

Anyway, please see if you can share any helpful tips. Thanks!
