stm32硬件I2C..初学者,在写HMC5883电子罗盘的驱动,用的硬件I2C,不管怎样硬件I2C总是会卡死,我是改的野火的EEProm里面硬件I2C的代码,调试中经常会卡在各种While循环里。。。要死要死的,昨天百度了
程序会一直停在`while(I2caRegs.I2CSTR.bit.XRDY == 0)`。这个问题通常是由于I2C总线上的通信没有...
// I2caRegs.I2CMDR.bit.MST = 1; //Set to Master mode // I2caRegs.I2CMDR.bit.FREE = 1; //Run in FREE mode // I2caRegs.I2CMDR.bit.STP = 1; //Stop when internal counter becomes 0 // I2caRegs.I2CMDR.bit.STT = 1; //Send the start bit, transmi...
sudo find / -name libi2c.so.0 通常,这个库文件应该位于/usr/lib/或/usr/lib/x86_64-linux-gnu/(对于64位系统)等目录下。 确认系统的环境变量是否包含了libi2c.so.0的路径: 你需要确保LD_LIBRARY_PATH环境变量包含了libi2c.so.0所在的目录。你可以通过以下命令来查看和设置这个环境变量: bash echo $...
return 用法求助bit I2CWaitAck(void) //返回为:1=有ACK,0=无ACK{ SCL=0; SDA=1; //设置SDA为输入 I2CWait(); SCL=1; I2CWait(); while(SDA) { SCL=0; return false; } SCL=0; return true;}以上是一个IIC等待应答的程序,ture 1.不太明白里面return的用法,请高手讲一下,谢谢! 扫码下载作业...

如果你是希望在G2553上实现一个I2C主机的话，可以参考430ware中的msp430g2xx3_uscib0_i2c_06例程，代码如下：#include <msp430.h> unsigned char TXData;unsigned char TXByteCtr;int main(void){ WDTCTL = WDTPW + WDTHOLD; // Stop WDT P1SEL |= BIT6 + BIT7; // Assign I2C pins to USCI_B0 P1...

This is tbe first result of googling "raspberry pi reboot not working" for me. From memory, I also had a rpi0w also bahaved the same. Unfortunately it is now dead so I could not test with it. It only booted off an microSD card. The symptomes are: rpi unable to reboot, just ...
