Hi Team,
I'm working on GLCDC RX72N.
I have came across the TCON setting for signal generation.
TCON0 and TCON1 is used for only => Vsync
TCON2 and TCON3 is used for only => Hsync
I have attached manual snap for the reference.
My understanding is correct, or I can use TCON0,1,2,3 for any signal generation like Hsync, Vsync, DE.
Hi Jef/Renesas support team,
waiting for your response!!
My setting are configured as mentioned below for the signal generation.
TCON0 - Vsync
TCON1 - Hsync
TCON3 - DE
Based upon the above setting I'm getting image as below. what caused the misalignment of image(x,y position) ?
Below image which I got LCD

Thanks
Hello Vishal,Thank you for reaching out. In order for me to help you better, can you please provide the resolution of your LCD and screen format that you have set in your RX72N?Regards,JefIf this response, or one provided by another user, answers your question, please verify the answer.

Hi Jef,
Thanks for the quick response.
I have attached the timing characteristic as below. If you need any further information please let me know.
I have used the RX72N Envision Kit LCD timing characteristic as well but the same result.
Hey Vishal,Would like to know if this issue is intermittent or shows this every time regardless of the output?Can you also please share your config that you have set-up?Regards,JefIf this response, or one provided by another user, answers your question, please verify the answer.

Thanks for response,
I have used the same setting as per the RX72N Envision kit, I'm concerned about the Hsync, Vsync and DE synchronization. I'm Using Channel A.
In above message I have mentioned that I'm using Hsync on TCON1, Vsync on TCON0, DE on TCON3.
Hsync connected to pin P12, Vsync is P13 and DE is PJ1.
For Hsync TCONSTHy1, TCONSTHy2 and For Vsync TCONSTVy1, TCONSTVy2 are dedicated registers.
SEL[2:0] has mentioned for vertical and horizontal has specific TCON.
Below image is TCONSTVy2 register setting.
Below image is TCONSTHy2 register setting.
Above images have clearly mention that TCON0/TCON1 are for vertical setting and whereas TCON2/TCON3 are for Horizontal setting.
In my case I attached TCON1 to the Horizontal.
I hope you understand my issue.
Hello Vishal,Let me try to investigate and get back to you. I appreciate your patience.Regards,JefIf this response, or one provided by another user, answers your question, please verify the answer.

Hello Vishal,May I know why you are using TCON 1 for Horizontal? I suggest you calibrate your display using QE for Display. Kindly check out this application note : R20AN0487EJ0110. Also, you need to match the output pins with the following:Regards,JefIf this response, or one provided by another user, answers your question, please verify the answer.

Thanks for your response. I will check into that.
I have one more query regarding frame buffer toggling.
In Application note of RX72N QE for display has a function called R_GLCDC_BufferChange for frame buffer 1 and 2 toggle, but not available in RX72N Envision kit sample code.
My requirement is to toggle the frame buffers, so could you please help me with the full defined function.
I have attached snap of application note.
Vishal
