Thanks to the above, it works after adding the op amp. Now it is switched to voltage mode, but the light is not on again. I adjusted the LED current to a very low level, and the light is on. Later, I ...
Dear experts, please help me. When I use the SPI master-slave routine of MSP430F6638, the data UCA0TXBUF of the master is indeed increasing. When I debug the slave, I find that it does not enter the U...
How long does it take to perform a multiplication operation in EVC? I used a function to measure that it takes nearly 10 microseconds, which is too time-consuming. Does anyone have any solution to the...
We are all adults, we should have some ability to distinguish right from wrong!!!This morning, when I turned on my computer, a L-shaped full-screen advertisement popped up, saying something like "360'...
Dear XDJM:At present, the FPGA section adopts a porridge forum style. I personally feel that this style cannot quickly satisfy the forum friends who come to the FPGA section to obtain or exchange info...
