Any ideas on how to control the I2C stop condition on the CYW20719B2 under MTB 1.1 and SDK 1.4? Currently the wiced_hal_i2c doesn’t seem to allow that. Is there an API that can be exposed or a hidden parameter of the current API's that will allow control of the I2C transaction. ...

但根据Example_2833xI2C_eeprom.c例程中的注释: // If a message receives a NACK during the address setup portion of the // EEPROM read, the code further below included in the register access ready // interrupt source code will generate a stop condition. After the stop // condition is...

if you set a stop condition, it needs a little bit time the time is specified as 4,7µs in standard mode and 1,3 µs in Fast Mode only after that time the bus is free. i think you can try to read the I2CSTAT register.If all is ready, the status is 0xF8 else...
When code commands the transmission of the stop condition it initiates the process in the controller but the time that it takes for it to complete depends on the synchronisation of the clock domains used by the I2C controller and the CPU's clocks, the speed of the I2C bus (e...
The use of this so-called "repeated start" is common in I2C. A Stop condition ALWAYS denotes the END of a transmission. Even if it is issued in the middle of a transaction or in the middle of a byte. It is "good behavior" for a chip that, in this case, it disregards the ...
I2C_sendStartCondition(I2CA_BASE); I2C_sendStopCondition(I2CA_BASE); return(I2C_SUCCESS); } 发送函数如上,根据例程修改的。放在主函数中循环运行。 上面一共是两个问题: 1.为什么置位了STP没有正常发送; 2.为什么会重新START; 主要关注点在1,我想问I2C在什么情况下会不发送STOP到...
