在配置完成IIC从机模式后，主机向从机发送9位数据，在从机收到数据后主函数的代码会跑不到，不知道在什么地方造成了阻塞，接收完毕会产生多次的STPDEF中断吗，但是IIC从机模式的故障应该也不会影响到主函数的运行才对，有没有懂的大佬帮忙分析一下谢谢，代码如下[color=#dadada][backcolor=rgb(30, 30, 30)][font=Consolas,

这段代码执行的是SPI收发功能，使用仿真器debug时会停在spi_i2s_data_receive处（等待接收标志位），但是如果把datasize改成8bit就能正常收发数据，请问是什么原因呢? uint32_t Spi_Transfer16(SPI_BusDef *spi, uint16_t *TxBuf, uint16_t *RxBuf,uint16_t len) { uint32_t ret= 0; Spi_Nss(spi->Nss, 0); spi_master_transfer_start(spi->Periph, SPI_TRANS_START); for(int i = 0; iPeriph) & SPI_FLAG_TP)); spi_i2s_data_transmit(spi->Periph, TxBuf[i]); RxBuf[i] = spi_i2s_data_receive(spi->Periph); } while (RESET == spi_i2s_flag_get(spi->Periph, SPI_FLAG_TC)); Spi_Nss(spi->Nss, 1); return ret; }

[i=s] 本帖最后由 66ccff 于 2024-8-12 08:34 编辑 [/i] 我想在ubuntu上开发hc32，clion编译环境已经搭好了，但是hc32没有对应的openocd，无法下载调试有大佬指导一下吗

[i=s] 本帖最后由 lsfsxfljj 于 2024-7-29 14:57 编辑 [/i] [attach]2280622[/attach]见参考的是HC32M120J6TB电机驱动MCU板，原理图名为MD_CTL_M120_LQ48_Rev1.0。连不上JLINK，发现里面有MD口R6接地了，R6修改到接5V；C3从100nf修改到470nf。仍然连不上。仔细观察MCU无虚焊，2个板子都是同一情况。

03x系列带VCCLDO引脚的芯片，系统实际只有5V和3.3V供电，可以不用芯片内部LDO，直接在AVDD引脚上给5V或者3.3V吗？

求一份 eclipce 开发autochips ac7811 环境设置配置教程。

跪求大佬资料分享！！

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！

GigaDevice MCU 想自己写bootloader烧录程序，不知道怎么写。请教各路大神。

Hi 各位大牛，一个项目上用到GD32F305ZET6这款单片机，最近遇到个很困惑的问题描述如下： 1、QFP-144pin封装，只用到PA0（wakeup pin），ADC、I2C、UART以及少部分GPIO作为输入输出，12M的无源晶振作为MCU时钟，3.3V供电； 2、常温环境下，上电运行一切正常，跑了一段时间后发现MCU已经跑死，不响应外围IO上的高低电平信号，UART等接口均无响应； 3、按下NRST复位开关，MCU仍没有任何响应； 4、加看门狗后发现出问题时，看门口也无法复位； 5、电源供电，NRST电路等均按照手册要求设计，时钟波形均测量正常，并且没有发现异常case； 6、没有找到导致MCU跑死的必发路径，询问原厂FAE说可能是cache有问题，所以即使复位NRST管脚也不会重新加载cache，单问题是什么情况会导致cache异常，除cache外还有没有其他可能异常点； 综合看起来像是硬件上出问题了，这种情况还是第一次遇到。 以上，请各路大神帮忙看一下什么问题，谢谢!

307大家有在rt-thread中用flashdb保存参数的吗？为什么kv越多越慢呢？ 由于设备参数太多，估计有2000--3000条。运行日志也需要保存下来。所以我用了w25q32，采用flashdb来保存参数和日志。 但是实际使用中发现flashdb随着参数写入的增多，写入速度越来越慢，读取速度也越来越慢。不知道大家遇到过没有，如何解决这个问题呢？或者有其他嵌入式好用的KV数据推荐吗？

有国民技术mcu交流的群吗
