问答

目前用ARM v9的4根线对接了GD32的4个针（vcc、gnd、dio、clk），另外一个数据线接到pc的usb口上。这样下载没有问题，但是用串口助手调试uart时，找不到找不到串口。请问有办法吗？谢谢目前的连线： [url=/data/attachment/album/202408/14/115230vio6d61i1dp11pow.jpg][img]/data/attachment/album/202408/14/115230vio6d61i1dp11pow.jpg[/img][/url][url=/data/attachment/album/202408/14/115230vio6d61i1dp11pow.jpg][img]/data/attachment/album/202408/14/115230vio6d61i1dp11pow.jpg[/img][/url]

有没有前辈有相关的例程呢，小弟我这边一直调试不通，官方给的代码也只有同步采样的，并没有涉及到多重adc交替采样，希望大佬们不吝赐教

再调试过程中发现再使用串口0收发数据时，如果调用复位函数NVIC_System_Reset()就会导致程序网络不通，而且也没有复位重启，串口0停止收发数据就不会出现这个问题，而且其他串口均不存在这个问题，怀疑是不是串口0有调试串口的功能，还是别的什么原因导致的。

J-Link GDB Server failed: Device name 'AT32F403AVGT7' not recognised. Please check http://www.segger.com/supported-devices.html for the supported device names. For more details, see the JLinkGDBServerCL.exe console. PS：Segger_AT32MCU_AddOn.exe 这个也安装了，为啥在AT32IDE中用Jlink调试时仍然显示找不到芯片 求大佬帮忙

目前用keil ，想换其他的或者IAR 用哪个版本比较合适。 主要能够方便用的。 eclipc 如果有环境搭建教程也可以推荐下。 谢谢！

使用keil调试hc32l130f8ua时，SystemInit函数中的M0P_SYSCTRL->RCL_CR_f.TRIM = (*((volatile uint16_t*) (0x00100C22ul)));报错没有读的权限 *** error 65: access violation at 0x00100C22 : no 'read' permission void SystemInit(void) { M0P_SYSCTRL->RCL_CR_f.TRIM = (*((volatile uint16_t*) (0x00100C22ul))); M0P_SYSCTRL->RCH_CR_f.TRIM = (*((volatile uint16_t*) (0x00100C08ul))); SystemCoreClockUpdate(); _HidePinInit(); }

需要用到两个IIC接口（一个作为master，另一个作为slave）、调试接口、一个GPIO口做控制信号谢谢！

大神好！mcu型号：GD32E2308，ide：iar 9.30.1，仿真器：GD-LINK（cmsis-dap)，调试中无法停止Timer13计数。我试了两种方式，一是直接修改寄存器DBGMCU CTL0的位TIMER13_HOLD，二是调用函数dbg_periph_enable(DBG_TIMER13_HOLD);都不成功，CTL0总是全0，请问该如何做才能在调试中停止Timer13计数？谢谢！ 搜索 [align=left]复制[/align]

仔细看了《HC32L110_HC32F003_HC32F005系列的MCU开发工具用户手册Rev1.0.pdf》关于uart的部分，是这样描述的： [i][color=#000080][color=#000][font=TimesNewRomanPSMT][size=14.04pt]3.1.4 UART [/size][/font][/color][font=宋体][size=14.04pt]接口[/size][/font][/color][/i] [i][color=#000080][font=TimesNewRomanPSMT][size=11.04pt]STK [/size][/font][font=宋体][size=11.04pt]在板调试模块预留了 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]1 [/size][/font][font=宋体][size=11.04pt]组 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]UART [/size][/font][font=宋体][size=11.04pt]接口，需要使用 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]MCU [/size][/font][font=宋体][size=11.04pt]串口功能时，请将 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]UART [/size][/font][font=宋体][size=11.04pt]接口 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]CN8[/size][/font][/color][/i] [i][color=#f00000][color=#000080][font=宋体][size=11.04pt]上的信号通过飞线连接至 [/size][/font][font=TimesNewRomanPSMT][size=11.04pt]MCU [/size][/font][/color][color=#000][font=宋体][size=11.04pt][color=#000080]对应串口引脚。[/color][/size][/font][/color][/color][/i] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000][color=#f00000]查看了原理图，好像和开发板的对不上，比如：调试板上没有CN3,PCB板的部分电路和开发板的也不一致。[/color][/color] [/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt]我理解了半天，也没搞明白该怎么接。比如：[/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt]1.提供的样例程序是用P35,P36端口作为uart1_tx和uart1_rx的，但检查了线路，丝印为CN2上的P35，P36已经和MCU对应的引脚原本就是连着的。(PCB板上画的是CN7,CN8,但开发板的丝印上却是：CN2,CN3,每个引脚实际上都已经连到CN2和CN3上了)[/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000]2.查看原理图，貌似是通过飞线，把P35替换掉CN2的io的pin上，把p36插到cn2的clk上，然后用串口线连到调试板的J5的：gnd，Txd，Rxd上。我把uart_int的程序编译烧进去后，这样跳线接了一下，但没任何反应。[/color][/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000]请专家指点，该怎么接，才能调试uart的串口通讯？[/color][/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000]PS:我已经把调试板和开发板掰开了。[/color][/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000] [/color][/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000] [/color][/size][/font][/color][/color] [color=#f00000][color=#000][font=宋体][size=11.04pt][color=#f00000] [/color][/size][/font][/color][/color]

最近在用GDE230这款芯片，在调试外设时，串口，SPI,I2C,定时器，都没问题，但是只要综合起来，就会有一大堆问题，按照ST的开发流程，踩雷断腿搜索 [align=left]复制[/align]

我是一个新手，我IIC程序都编译成功了，DSView捕获波形的时候SDA没有波形，应该是没有往里面写入寄存器地址和数据，如果往地址0x02写入0xaa,不知道怎么往里写入.[img][/img]

什么型号单片机支持OCD调试

这两天在调试tft屏上带的触控功能ic---ADS7843，但是无论用STM32F107的GPIO模拟spi或是SPI3，读出来的数据都是oxfff
