Hi all, 8051 micro is very new to me. Does anybody in this forum kind enough to help me to create a routine to perform A/D and D/A so that it can be interfaced to a serial A/D or D/A converters using SPI protocol? or may be somebody can instruct me to the right site on the internet? The project I am working on requires that a standard 8051 micro to interface with the MAX187 ADC. Thanks in advance Jimmy Sayavong jsayavong@perkinselectronics.com
Btw. i have i2c ADC and had read the ADC manual and implement it. but what i confuse is, its still not working, it didnt send any message to my Com-terminal. Yes, you are confused. What on earth does the ADC have to do with serial communications?. Divide and conquer. You have coded the whole thing and do not know what works and what not. Take the serial comm parts only, disable the rest. Then try to send a character (use emulator - simulator or whatever you have) and when that works start working on making the content of the comm the ADC results. Erik
