I've been itching to buy an Infineon board these past two days, and I regret not cutting off my hands in advance on Double Eleven. Now I'm mainly choosing between [b]KITXMC48AUTBASEV2TOBO1 and KITXMC4...
[i=s]This post was last edited by dontium on 2015-1-23 11:26[/i] For TMS320F2802, I measured ADCREFP and ADCREFM to be 1.01V and 0.48V respectively, and the AD sampling is always 1768. Why is this?...
I am using the EK-LM3S811 development board. During the process of porting uCOS, I tested two pins, PB1 and PC5 (JTAG pins are not reused). I was able to download and debug several times, but suddenly...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
