The most impressive thing about 430 is its low power consumption! In addition, it is a 16-bit microcontroller. Coupled with the power of IAR, developing 430 becomes a breeze.
It has a wide range of pe...
Hello everyone:As shown in the figure, the voltage at point A is 5.8 Vp-p, and the voltage at point B is 6 Vp-p. If the capacitive reactance of C1 and C2 is ignored,how can I calculate the effective v...
How to generate a smooth curve by randomly clicking any number of points on the screen? It seems to be a quadratic spline algorithm. I wrote one myself but it doesn't work well. I hope someone who kno...
I don't often visit the forum. Add my QQ=762827135. I bought a TI original eight-core DSP evaluation module in April this year. I sell it for 2300RMB. I can also exchange it for a Freescale car, a qua...
The C2000 SPI sends 8-bit data, but the manual does not contain any specific instructions on how to do it.
When using F28035 to drive the serial 12864, I used SPI. After a long time of debugging, I co...
