Description: Welcome to the software files for the ADS8361 to TMS320F2812!
There are two project files in each of the folders McBSP, SPI and Both. Mode II and IV are explored using the McBSP port alone, as well as the SPI port. These projects are located in the SPI and McBSP folders.
Modes I and III are explored using both McBSP and SPI. In Mode I, the M0 and M1 pins are controlled by use of the jumper on the evaluation module. A0 is controlled by the DX pin of the McBSP port. In Mode III, the A0, M0 and M1 pins are controlled via GPIO functions of PortF.
The \"SRC\", \"CMD\" and \"INCLUDE\" files in the archive are from \"C28x Peripheral Examples in C\" (document # SPRC097). If you have questions about this or other Data Converter products, feel free to e-mail us at:

Description: 本源码维MSP430F149控制IIC协议的AD芯片DAC5571，并再1602液晶上显示数据
MCU的P1.0、P1.1 端口与DAC5571 的SDA、SCK端口连接，通过在两个GPIO上模拟
I2C时序从而实现对DAC的操作。可以看到，DAC5571
的输出端Vout连接到了跳线座P7 的第 1 脚。如果用短路帽将跳线座J1 的 2 脚
和 3 脚连接，则DAC的输出直接驱动LED，可以通过LED亮度的变化直观地观察到
DAC输出电压值的变化；如果用短路帽将跳线座J1 的2 脚和1 脚连接，则可以用
MSP430 内置的ADC对DAC输出的电压进行采样转换，对ADC和DAC电路同时进行应用。-MSP430F149-dimensional control of the source of the AD Agreement IIC chip DAC5571, and another 1602 on the display data LCD MCU of P1.0, P1.1 ports of the DAC5571 and SDA, SCK-port connectivity, through two GPIO on I2C timing simulation in order to achieve DAC operation. Can be seen, DAC5571 output Vout is connected to a jumper P7 Block 1 foot. If the cap will short-circuit jumper J1 Block, 2 pin and 3 pin connection, the DAC output to directly drive LED, through the LED brightness can be visually observed changes in DAC output voltage changes in value If the cap will short-circuit jumper Block J1 2 feet and 1 foot to connect, you can use the built-in ADC of the MSP430 output voltage DAC sampling conversion of ADC and DAC circuit applications at the same time.

Description: STM32作为主控芯片，72Mhz，利用DMA+PWM实现驱动WS2812，创建16个并行800kBit / s数据流的想法如下：
使用定时器每1.25us创建一个800kHz的时基和一个DMA请求。
使用2个比较模块在低位时间（350ns）和高位时间（700ns）下创建DMA请求
1.25us DMA请求将GPIO端口的所有位设置为高电平
350ns DMA请求将数据从帧缓冲区传输到GPIO端口。如果该位为0，GPIO引脚将变为低电平，否则将保持高电平。
700ns DMA请求将所有GPIO引脚设置为低电平。
重复步骤1到3，直到发送所有位。
这产生脉冲周期为1.25us，脉冲宽度为350ns或700ns的脉冲流，具体取决于脉冲表示的位值，通过DMA将数据传输到GPIO端口意味着每16个LED每位需要一个字（两个字节）。每个LED 24位，每16个LED 24个字（48个字节）。(The idea to create 16 parallel 800kBit/s data streams is the following:
Use a Timer to create an 800kHz time base and a DMA request every 1.25us.
Use 2 compare modules to create DMA requests at the low bit time (350ns) and the high bit time (700ns)
The 1.25us DMA request sets all bits of the GPIO port high
The 350ns DMA request transfers the data from the frame buffer to the GPIO port. If the bit is a 0, the GPIO pin will go low, otherwise it will stay high.
The 700ns DMA request sets all GPIO pins low.
Repeat steps 1 to 3 until all bits have been transmitted.
This creates a stream of pulses with a pulse period of 1.25us and a pulse width of either 350ns or 700ns depending on the bit value the pulse represents.
Transferring the data via DMA to the GPIO port means that per 16 LEDs one half word (two bytes) is needed per bit. At 24 bits per LED that makes 24 half words (48 bytes) per 16 LEDs.)
