below.Figure 1:opa857 Block diagramThere is three distinct blocks in this diagram: Transimpedance Block Reference Voltage Block Current mirror block (test block) The transimpedance block has the selectable gain configurations:4.5k? and 18.2k? When taking into consideration the attenuation due to a 500? Load. Since There is only one switch, and the parallel combination of the RF2 with RF1 is 4.5k?. The schematic is simplified to ensure, the resulting value is represented cl

the open source community. Its shortage is only open software source code, and not open hardware schematic, but this does not affect the creators of its favor.7.udoo-Freescale i.mx6 ARMLike the Raspberry Pi, Udoo is an arm-architected Linux board, and a second ARM processor is installed on the board to emulate the Arduino Due.The Udoo has a dual-core and four-core two-version arm cortex-a9 CPU with an arm sam3x processor like the Arduino due. The Udoo also includes OpenGL accelerators, 54 digit

STM32 UART Single-line half-duplex mode (cube version) 1. IntroductionIn some cases, a three-wire serial communication is required (only one of the signal lines), which requires a single-line half-duplex mode for communication. In this case, in the process of data protocol transmission, the signal end needs to switch back and forth in the input and output mode. Alternatively, the transmit and interface of the control port can be short-connected. In this case, STM32 provides the Half-duplex funct

bit reserved, low 16 can be read at any time, 1 means the corresponding configuration bit is activated latch, 0 means can be activated, activation is a fixed write shunThe order. Latches can not be used indiscriminately, if a function register of a port is locked, then the function of the port can not be changed before the next system reset, which is advantageous in some cases, especially if the program is heavyWhen defining the functionality of certain GPIO ports, it is necessary to ensure tha

1. In the pinout option, all the system used pins are configured, including two osc,jtag/swd, BOOT0/1, so that all unused pins can be set to analog, otherwise it will not download the program.2. For the JTAG has been configured for other functions, but unable to write the program, the boot0 changed to 1 and then press reset and then the emulator is good, because boot0 changed to 1, does not start from flash, JTAG pin will not be initialized, When usin

Iis-iis Concept Related1. IIS (Inter-ic Sound bus), also known as I2S, is a serial digital audio bus protocol proposed by Philip. Currently, many audio chips and MCUs provide support for IIS. The IIS bus processes only sound data. Other signals, such as control signals, must be transmitted separately. To keep the chip's pinout as small as possible, IIS uses only three serial buses. These three lines are: data lines that provide time-sharing, field sel
