I am in a process to interface some external slave device to the esp8266EX Launcher using HSPI.Currently I am using the spi driver found here https://github.com/MetalPhreak/ESP8266_SPI_Driver and it seems to be working pretty well. I am controlling the CS line manually through software.
The problem is, whenever I transfer two bytes of data, between each byte transfers, there is 8 dead clock cycles as shown in the image attached below. So basically, I want to get rid of those dead cycles and send the 2 bytes in a row, like this:
1. Make CS Low
2. Send 2 bytes of data
3. Make CS High
Any suggestions or help regarding this would be greatly appreciated.
