Discussion - EVE / Eve Screen Designer - 480 x 272 resolution

« on: August 10, 2020, 01:31:45 PM »

Hello,

How can I generate code for an 4.3" LCD with 480 x 272 resolution? Can't find this resolution in the program.

I am using NHD-4.3-480272FT-CSXN-CTP from New Haven Display

Hello,

Thank your for your answers. I have written to the email address regarding the hardened displays against EMI/EMC.

About the software timeout, we have already added such a recovery case (see the below link). I would be happy if you can comment for further improvements.

Hello,

Due to EMI issues, the connection between FT813 and New Haven TFT controller IC sometimes gets broken.
We end up with a black or white screen. FT813 doesn't give any errors regarging this case.

See below link for details

How can we handle this error?

Discussion - EVE / Eve Screen Designer Code Hangs - additional error handling required

« on: June 16, 2020, 05:11:14 PM »

Hello,

Due to EMI issues, sometimes our application hangs at ESD_WaitSwap() function

We traced the problem to below function EVE_Cmd_waitFlush.
while ((rp = EVE_Cmd_rp(phost)) != (wp = EVE_Cmd_wp(phost))) needs a break addition.

Our application has a part that produces 320V, 1.2A for a couple of seconds. The coprocessor doesn't give any errors but the code hangs at the above while loop.

We implemented the following case, your comments on to why and how to get rid of / handle this error are welcomed.
Our board is NHD-3.5-320240FT-CSXN-CTP from New Haven (has an FT813 on it)

Code: [Select]

bool EVE_Cmd_waitFlush(EVE_HalContext *phost)
{
	uint16_t rp, wp;
	uint16_t flushCnt = 0;

	eve_assert(!phost->CmdWaiting);
	phost->CmdWaiting = true;
	while ((rp = EVE_Cmd_rp(phost)) != (wp = EVE_Cmd_wp(phost)))
	{
		flushCnt++;
		if(flushCnt >= 200){
			flushCnt = 0;
			eve_stop_flag = 1;
			eve_printf_debug("[ERR-394]flushCnt >= 200\n");
			break;
		}

		// eve_printf_debug("Waiting for CoCmd FIFO... rp: %i, wp: %i\n", (int)rp, (int)wp);
		if (!handleWait(phost, rp))
			return false;
	}

	/* Command buffer empty */
	phost->CmdWaiting = false;
	return true;
}
