The pins CAP1_QEP1, CAP2_QEP2, and CAP3_QEPI1 of F2810 are used as GPIO signal input terminals. I set:GpioMuxRegs.GPAMUX.all = 0x00;GpioMuxRegs.GPADIR.all = 0xFF00;GpioMuxRegs.GPAQUAL.all = 0x0000;(1)...
[i=s]This post was last edited by jordanwys on 2014-7-3 09:40[/i] Due to the jitter of the motor (the resonance area of the stepper motor, it has been debugged for a long time, but it is still impossi...
I would like to ask how much data lwip UDP can receive at a time. I don't know which parameter controls the size of the received data. I can now receive 4KB of data, but if it is larger (such as 5K), ...
I use the msp430afe253 chip. When I used the SD24 interrupt before, I needed to pause the operation before entering the interrupt. At that time, the clock source was set to SMCLK. Later, I accidentall...
