Your example is quite strange because you want to write also into the device register 0x1a. did you try i2cset -y 1 0x1a 0x1a 0x01 0xf8 i sorry for late response. Both Its I2C address and register address are 0x1a. I am using wm8960 Audio Raspberry Hat. I will try "i2cset -y...
设备驱动和设备通过名称"nuc970-i2c0"匹配相等(具体可以参考之前写的一篇文章: ,调用探测函数nuc970_i2c0_probe(...)进行驱动注册。 4.2 i2c probe(...) AI检测代码解析 staticintnuc970_i2c0_probe(structplatform_device*pdev) { structnuc970_i2c*i2c; structnuc970_platform_i2c*pdata; structresource*res...
Whilst this can be easily (but somewhat slowly for the second device) achieved via (a 'C' system call to) i2cset such as in this example (diagnostic output from my program): Code: Select all i2cset -y 1 0x3a 0x01 0x43 0x4c 0x31 0x20 0x4c 0x43 0x4d 0x31 0x36 0x30 0x32 ...
Example of overriding the first 4 bytes of EEPROM chip data with new data in a single I2C write transaction performed withi2csetand then withi2ctransfer. Read the content of the first 4 bytes: $ sudo i2cset -y 1 0x57 0 $ sudo i2cget -y 1 0x57 0x00 $ sudo i2cget -y 1 0x57 0x...
Setting pins and the board is redundant in the I2SCodecStream. Is there an alternative I2S stream setup or shall I try to modify your codec stream code so that if the board is already initialized it does not do it again? I took ino example from AudioDriver. ...
For example, multiple OLED displays or multiple BME280 sensors? There are several solutions. change the device I2C address; use an I2C multiplexer. Changing the I2C address Many breakout boards have the option to change the I2C address depending on its circuitry. For example, that a look at ...
I am trying to use I2C with the S32K144 EVB. I decided to start with the flexio_i2c_s32k144 SDK example project from the S32SDK_S32K1xx_RTM_3.0.0. After facing several issues, and debugging the project, I have found the following: When compiling the flexio_i2c_s32k144 SDK...
