I'm trying to understand the USB setup. I have a board that has a USB connector connected to the DP and DM pins on the PSOC5. I copied the code from the USBFS example and it runs, but hangs when trying to check the configuration. That appears to be because the Windows 10 computer does not recognize the USB device. It shows up in device manager under "Universal Serial Bus controllers", as "Unknown USB device (Device Descriptor Request Failed)". I am not sure if this is a hardware or software issue. The various documents seem to indicate that I have to find and install a special Windows device driver for the USBFS. I followed the instructions to install it but when I selected the .inf file, I got a message that a compatible file was not found. (That was when trying to install the driver from the unknown USB device entry in device manager.)
In general, why should I need a special device driver? I want to produce a product that creates a com port for anyone who installs it into windows. Why won't the Ftdi drivers work? Is there any path to making them work?
But, from reading, I am not at all sure that this is a driver problem.
Help please.
Thanks Russ

Show LessHi
I am trying to create a simple program to read 10 bytes on UART through DMA and then write it again to the UART using DMA.
I added blinking LEDs in the DMATxISR and DMARxISR as visual indication that the ISR is being called.
It works for DMA Rx, but fails in DMA Tx.
I tried to use memcpy() to copy the Rx buffer into the Tx buffer to engage DMATx, but it doesn't work. I can only send using PutArray().
I attached my project,
I wonder if you can help me out find the mistake.
thanks
Show LessHi.
I'm a student. I have a PCB with the SAK-TC214L-8F133 chip on it. I would like to be able to connect to it using Memtool. I see Memtool supports this layout. I have a USB-UART converter.
How should I connect from the hardware side? Connect TxD from the converter to P14.1 (ASCLIN0_RXA) and RxD to P14.0 (ASCLIN0_TX)? I did that, but Memtool does not detect the chip. Do I need to short any configuration pins to VCC/GND?
I will be grateful for your help.
Hi,
I was recently working with TC387.
I need to save some variables during standby mode, and after waking up, their value should not be initialized. I found the DLMU in the user manual, it is described as follows:
The data tested is defined in data section lmudata_cpu0, and the variable is successfully mapped.
Then before getting into standby mode, i changed the variable value to 0xAA.
At last, the standby mode gets into(the standby RAM is correctly selected).
But after waking up, the variable is still initialized with 0x55.
So could someone tell me why DLMU performs different from what the user manual has said, did i ignore something important?
Thanks!

Show LessHello,
I am curious to know does IAR IDE, programmer tools support in Linux(Debian)OS.
I know its not a right forum to ask here.
It would be really helpful to know this.
Thanks

Show LessHi guys , I want to use freeRtos with psoc4 and my mcu is cy8c4248azi and I followed this guide : have a only one difference guide uses freeRtosV9.0.0 I used freeRTOSV202012.00
https://iotexpert.com/psoc4-freertos-port/
and I got this errors :
Do you have any idea what is the problem?
Show Less大家好 :
关于ADC和DMA 有几个疑问,想得到帮助。
1.官方例程TLE9879_DMA_ADC1中,adc_ch_result[DMA_CH0_NoOfTrans]数组设置为8,但是IFXCONFIG里面,图1所示序列模式勾选了14个(7个通道+7个通道4重复采集),那么这个地方,DMA在传数的时候,是不是把前几个就给覆盖了?
2.DMA配置里,ADC1->RES_OUT7.reg这个配置是干嘛用的?
3.DMA完成中断触发条件是什么,是完成一个通道还是完成整个一次多通道扫描?
4.采集的数为什么设置为32位的,ADC是12位的。
5.如果我想测量2通道的ADC的数,一个P2.4的电压+一个VDH的电压,循环扫描,实时更新,该怎么配置。
因为资料较少,看了半天文档也是不明所以,希望得到解答。
