Hi,
I am using Quectel SC20 module with android version of 7.1.2. I am currently using the SC20 Smart EVB kit. I want to test the I2C and SPI on the EVB, as I want to interface an external peripheral to the SC20 module. Please do provide me the link for the demo apk for I2C and SPI, using which I can test I2C and SPI. Any help will be highly appreciated.
Thanks,
for I2c, you can use standard interface on user space.
for spi, there are spidev for test. how to use this? you can reference to these documents (path: kernel\Documentation\spi)
