I spent half a day repairing the board yesterday, only to find that the original code could not run normally. I followed it step by step and finally found that it was an interrupt problem. The problem...
I asked three questions about ads1232 in a row, but no one answered. It seems that the so-called experts really don’t exist. I am a rookie and just came to the company for internship. I just want to a...
Why can't TACCR0 be assigned a variable? For example: TACTL = TBSSEL_2 + TBCLR; TACCTL0 = CCIE; TACCR0=X; TACTL|=MC_1; where X is an unsigned int type variable, and the compiler used is IAR5.3?...
CD4046 is selected as the frequency multiplier, and the input frequency 50HZ is multiplied by 256 times to control AD sampling, but the output frequency keeps jumping. And later when debugging, I dire...
If 12864 uses parallel driver, many I/O ports will be occupied. If serial driver is used, many I/O ports can be saved. Can anyone write a serial driver for 12864? Can you upload it? Thank you!...
